The emulsifier is the conductor, but miss a single instrument \u2014 the filler, the seamer, the labeler \u2014 and the performance never reaches the audience.<\/p>\n <h2>Core Equipment in a Mayonnaise Production Line<\/h2>\n <p>The equipment you select for each stage turns on three variables: your formula type (full-fat, low-fat, or vegan), your target throughput, and your packaging format. The three workhorses below form the backbone of most lines.<\/p>\n <h3>Vacuum Emulsifier: The Heart of the Line<\/h3>\n <img decoding=\"async\" src=\"https:\/\/www.levapack.com\/wp-content\/uploads\/2026\/08\/mayonnaise-production-line-3.webp\" alt=\"Vacuum Emulsifier\" style=\"width: 512px !important; height: auto !important; display: block !important; margin: 24px auto !important; border-radius: 12px !important; box-shadow: 0 10px 25px rgba(0,0,0,0.15) !important; max-width: 100% !important;\">\n <p>The vacuum emulsifier is the most expensive and most technically demanding single machine on a mayonnaise line. It integrates mixing, high-shear emulsification, vacuum deaeration, and temperature control into one vessel \u2014 and the quality of what happens inside it determines everything downstream.<\/p>\n <p>At its core, a rotor-stator homogenizer spins at tip speeds of 10\u201350 meters per second, shearing the oil phase into micron-scale droplets as it enters the water phase. The vacuum environment \u2014 typically -0.06 to -0.09 MPa \u2014 is not a luxury; it is a functional necessity. Without vacuum, air becomes entrained in the emulsion, causing oxidation, off-flavors, and a shortened shelf life. Oil dosing rate is a critical productivity lever: industrial systems can introduce oil at up to 3 kg\/s without breaking the emulsion.<\/p>\n <p>Commercial emulsifiers range from 100-liter pilot units to 2,000-liter production vessels, built from SUS304 or SUS316L food-grade stainless steel. Key configuration choices include variable-frequency drives for independent control of the anchor agitator and the high-shear head, a triple-layer jacketed tank for heating and cooling, and integrated CIP spray balls for cleaning between batches. A typical emulsification cycle runs 20\u201330 minutes under cold process conditions (5\u201325\u00b0C), after which the mayonnaise is ready for transfer.<\/p>\n  <div class=\"bp-stat-grid bd-reveal\"> <div class=\"bp-stat-grid-header\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M3 3v18h18\"\/><path d=\"m19 9-5 5-4-4-3 3\"\/><\/svg> <span class=\"bp-stat-grid-title\">Mayonnaise by the Numbers<\/span> <\/div> <div class=\"bp-stat-grid-body\"> <div class=\"bp-stat-cell\"> <div class=\"bp-stat-num\">2\u201310 \u03bcm<\/div> <div class=\"bp-stat-label\">Oil Droplet Size<\/div> <\/div> <div class=\"bp-stat-cell\"> <div class=\"bp-stat-num\">10k\u2013100k<\/div> <div class=\"bp-stat-label\">Viscosity (cP)<\/div> <\/div> <div class=\"bp-stat-cell\"> <div class=\"bp-stat-num\">3.5\u20134.2<\/div> <div class=\"bp-stat-label\">pH Range<\/div> <\/div> <div class=\"bp-stat-cell\"> <div class=\"bp-stat-num\">20\u201330<\/div> <div class=\"bp-stat-label\">Cycle Time (min)<\/div> <\/div> <\/div> <\/div>\n <h3>Pasteurization Systems: When and Why You Need One<\/h3>\n <p>Not every mayonnaise line requires a pasteurizer. Traditional full-fat mayonnaise \u2014 with its low pH of 3.5\u20134.2 and high oil content \u2014 is naturally hostile to pathogens like Salmonella and E. coli. The acid does the preserving. What needs pasteurization is the raw egg ingredient, which responsible manufacturers source as pre-pasteurized liquid yolk or egg powder.<\/p>\n <p>Pasteurization at the product stage enters the picture with low-fat and starch-based formulations. These recipes replace some of the oil \u2014 and some of the egg \u2014 with starch and hydrocolloids like xanthan gum. The starch slurry must be cooked to activate its thickening and binding properties. This is where a Scraped Surface Heat Exchanger (SSHE) comes in: the product enters at 20\u201325\u00b0C, is heated to 80\u201390\u00b0C for 3\u20135 minutes, then rapidly cooled back to 5\u201320\u00b0C. The SSHE’s rotating blades prevent the viscous starch mixture from scorching against the hot wall.<\/p>\n <p>The rule of thumb is straightforward: if your recipe relies on egg yolk for emulsification and vinegar for preservation, you are on the cold path. If starch or gum carries part of the functional load, budget for a pasteurizer.<\/p>\n <h3>Filling Machines: Matching Your Packaging Format<\/h3>\n <p>The filling machine is where your packaging decision becomes a hardware decision \u2014 and mayonnaise is an unforgiving product to fill. With a viscosity of 10,000\u2013100,000 centipoise, it is roughly ten thousand times thicker than water. Gravity fillers will not work. Piston fillers are the standard choice for viscous products, delivering volumetric accuracy within \u00b11% at speeds of 20\u201360 containers per minute. Rotary piston fillers handle higher throughputs; servo-driven models offer recipe memory and quick changeover between container sizes.<\/p>\n <p>The filling head design must also account for mayonnaise’s thixotropic behavior \u2014 it thins under shear and thickens at rest. The filler exploits this by keeping the product under shear during dispensing, then allowing it to set inside the container. Filling temperature is held at 5\u201325\u00b0C; any warmer and the emulsion risks destabilizing.<\/p>\n <h2>From Emulsion to Package: Filling and Sealing Integration<\/h2>\n <p>Here is something the industry rarely discusses openly: most content about mayonnaise production lines stops at the emulsifier. Search for “mayonnaise production line” and you will find pages of detail about rotor-stator geometry, oil droplet distribution, and vacuum levels. Then, almost as an afterthought, a single sentence: “The product is then filled and packaged.”<\/p>\n <p>That sentence hides half the line \u2014 and arguably the half where more quality failures start.<\/p>\n <h3>Filling Systems for Viscous Products: Getting Mayo into the Container<\/h3>\n <img decoding=\"async\" src=\"https:\/\/www.levapack.com\/wp-content\/uploads\/2026\/08\/mayonnaise-production-line-1.webp\" alt=\"Filling Systems for Viscous Products\" style=\"width: 512px !important; height: auto !important; display: block !important; margin: 24px auto !important; border-radius: 12px !important; box-shadow: 0 10px 25px rgba(0,0,0,0.15) !important; max-width: 100% !important;\">\n <p>Mayonnaise does not pour. It does not flow predictably. It must be pushed, metered, and placed \u2014 and once inside the container, it must be sealed before oxygen can begin its work.<\/p>\n <p>The choice of filler type depends on container format and line speed. Piston fillers dominate for jars, bottles, and cans, offering the displacement precision needed for thick emulsions. For flexible pouches and sachets, vertical form-fill-seal machines integrate filling and sealing into a continuous motion. Net-weight fillers, which use load cells under each filling station, provide the highest accuracy for premium products where overfill represents real cost.<\/p>\n <p>A frequently overlooked consideration is the physical distance between the filler and the sealer. Mayonnaise begins oxidizing the moment it leaves the vacuum environment of the emulsifier. The shorter the conveyor between filling and sealing, the less oxygen exposure \u2014 and the longer the shelf life. In a well-designed line, filling and sealing stations sit within a few meters of each other on the same conveyor.<\/p>\n  <div class=\"bp-insight bd-reveal\"> <div class=\"bp-insight-body\"> <div class=\"bp-insight-headline\">The shorter the distance between filler and sealer, the longer the shelf life.<\/div> <div class=\"bp-insight-sub\">In a well-designed line, filling and sealing stations sit within a few meters of each other on the same conveyor \u2014 minimizing oxygen exposure from the moment the emulsion leaves vacuum.<\/div> <\/div> <div class=\"bp-insight-icon\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M15 14c.2-1 .7-1.7 1.5-2.5 1-.9 1.5-2.2 1.5-3.5A6 6 0 0 0 6 8c0 1 .2 2.2 1.5 3.5.7.7 1.3 1.5 1.5 2.5\"\/><path d=\"M9 18h6\"\/><path d=\"M10 22h4\"\/><\/svg> <\/div> <\/div>\n <h3>Sealing and Closure Systems: The Shelf-Life Gatekeeper<\/h3>\n <p>A mayonnaise jar that leaks \u2014 or worse, one that does not visibly leak but lets in enough oxygen to turn the surface rancid within weeks \u2014 is a recall in the making. The sealing system is the last machine to touch the product before it reaches the consumer.<\/p>\n <p>For glass jars, the standard is a screw capper applying metal or plastic lug caps at a controlled torque \u2014 typically 0.5\u20131.5 N\u00b7m for a standard 28 mm finish. Many lines add an aluminum foil induction sealer before capping: an electromagnetic field heats a foil laminate bonded to the jar rim, creating a hermetic barrier that doubles as tamper evidence.<\/p>\n <p>PET bottles and jars follow a similar pattern \u2014 foil induction seal plus screw cap \u2014 but require tighter process control because plastic threads deform more easily under torque. For metal cans, the closure technology is fundamentally different: a double-seam seamer rolls the can body flange and lid curl together into an interlocking fold. Seam integrity is measured by three parameters: seam width (1.25\u20131.45 mm), seam thickness (1.50\u20131.70 mm), and body hook overlap (\u226555%). A single seam that falls outside these tolerances can fail weeks after shipping \u2014 and by then, the entire batch is at risk.<\/p>\n <p>Flexible pouches use heat sealing, with jaw temperature, dwell time, and pressure calibrated to the specific film laminate. The common failure mode here is seal contamination: a droplet of mayonnaise on the sealing area prevents proper fusion, creating a weak point that bursts under transport pressure.<\/p>\n <h2>Can Packaging for Mayonnaise: What Production Managers Need to Know<\/h2>\n <p>Metal can packaging for mayonnaise occupies an interesting position in the market. It is not the dominant format \u2014 glass jars and PET bottles own most retail shelf space. But for export markets, foodservice, and premium gift packaging, cans offer distinct advantages: zero light transmission (no photo-oxidation), excellent oxygen barrier, no breakage risk in transit, and ambient-temperature storage without refrigeration.<\/p>\n <p>If you are considering can packaging for your mayonnaise line, the engineering requirements differ meaningfully from jar and bottle lines.<\/p>\n <h3>Can Types, Lining, and Seam Integrity for Mayo<\/h3>\n  <div class=\"bp-compare bd-reveal\"> <div class=\"bp-compare-grid\"> <div class=\"bp-compare-col\"> <div

products corrode bare metal. Every can destined for mayonnaise must carry an internal lacquer coating, typically epoxy or phenolic resin, applied at 6\u201310 grams per square meter. Without it, the product attacks the tinplate or aluminum, leaching metallic ions into the emulsion and discoloring the surface.<\/p>\n <p>Double-seam quality control deserves special emphasis in a mayonnaise line. Unlike a screw cap that you can inspect visually for cross-threading, a double seam hides its defects inside a folded metal structure. Production managers should budget for a seam inspection station \u2014 either a manual tear-down rig with a seam micrometer, or an automated vision system for higher-speed lines \u2014 and implement a sampling schedule (typically one can per seamer head per hour). The cost of this inspection is trivial compared to the cost of recalling a container shipment where 5% of the seams failed.<\/p>\n  <div class=\"bp-checklist bd-reveal\"> <div class=\"bp-checklist-title\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M12 22s8-4 8-10V5l-8-3-8 3v7c0 6 8 10 8 10z\"\/><\/svg> Seam Inspection Rule <\/div> <div class=\"bp-checklist-row\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M22 11.08V12a10 10 0 1 1-5.93-9.14\"\/><path d=\"m9 11 3 3L22 4\"\/><\/svg> Manual tear-down rig with seam micrometer, or automated vision system <\/div> <div class=\"bp-checklist-row\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M22 11.08V12a10 10 0 1 1-5.93-9.14\"\/><path d=\"m9 11 3 3L22 4\"\/><\/svg> Measure all three parameters: width (1.25\u20131.45 mm), thickness (1.50\u20131.70 mm), overlap (\u226555%) <\/div> <div class=\"bp-checklist-row\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M22 11.08V12a10 10 0 1 1-5.93-9.14\"\/><path d=\"m9 11 3 3L22 4\"\/><\/svg> Sample one can per seamer head per hour \u2014 every hour the line runs <\/div> <\/div>\n <h3>Vacuum Sealing and Nitrogen Flushing for Extended Shelf Life<\/h3>\n <p>Even a perfectly seamed can contains oxygen in its headspace \u2014 and oxygen is what turns oils rancid. Two methods address this. Vacuum sealing draws a negative pressure (-0.04 to -0.06 MPa) inside the can immediately before the seamer closes it, reducing the oxygen available for oxidation. Nitrogen flushing goes further: a jet of food-grade nitrogen (purity \u226599.5%) displaces the headspace atmosphere before sealing, pushing residual oxygen below 3% \u2014 and in high-end lines, below 1%.<\/p>\n <p>For mayonnaise, nitrogen flushing matters most when the formulation includes unsaturated oils \u2014 sunflower, rapeseed \u2014 that oxidize faster. The incremental equipment cost is modest next to the shelf-life gain: a product that might show rancidity at six months in a standard-sealed can can reach twelve months or more with nitrogen flushing.<\/p>\n <p><em>Most filling equipment suppliers focus on one stage \u2014 either the filler or the seamer \u2014 but few offer an integrated solution that covers both. For production managers evaluating can packaging for viscous products like mayonnaise, suppliers such as Levapack provide custom can filling and seaming lines that combine servo-driven piston fillers with vacuum and nitrogen-flush double seamers, configurable for tinplate, aluminum, or composite cans at speeds from 20 to 60 containers per minute. The advantage of a single-source line is that filling and sealing parameters are calibrated together, eliminating the integration risk of matching equipment from separate manufacturers.<\/em><\/p>\n  <div class=\"bp-cta-mid bd-reveal\"> <div class=\"bp-ctamid-icon\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"m22 2-7 20-4-9-9-4Z\"\/><path d=\"M22 2 11 13\"\/><\/svg> <\/div> <div class=\"bp-cta-mid-content\"> <div class=\"bp-cta-mid-text\">Need a custom can packaging line configured for your product?

Hot processing makes economic sense when the business model depends on lower raw material cost \u2014 starch is cheaper than egg yolk \u2014 or when the target market demands low-fat variants.<\/p>\n <h2>Key Factors When Investing in a Mayonnaise Production Line<\/h2>\n <p>By this point, the technical landscape should be clear. What remains is the commercial checklist \u2014 the questions to answer before you send a request for quotation.<\/p>\n <p><strong>Target throughput.<\/strong> A small-scale line producing 500 kg per day needs fundamentally different equipment than a 5,000-liter-per-hour industrial plant. Define your daily or hourly target before comparing machine specs. A line that is undersized on day one constrains growth; a line that is oversized wastes capital and floor space.<\/p>\n <p><strong>Formula type.<\/strong> Full-fat, low-fat, vegan, flavored \u2014 each pulls a different set of equipment. A full-fat line skips the pasteurizer. A low-fat line needs one. A vegan line replaces egg with plant-based lecithin, which may require adjustments to the emulsifier’s shear profile.<\/p>\n <p><strong>Packaging format.<\/strong> Glass jars, PET bottles, metal cans, or flexible pouches \u2014 the decision dictates your filler type, your sealer or capper, and your labeling system. It also affects shelf life, shipping cost, and retail positioning. Make this decision before you buy any equipment.<\/p>\n <p><strong>Target market regulations.<\/strong> FDA, EU, and export-market food safety standards impose different requirements on material traceability, CIP validation, and allergen control. Equipment that passes one jurisdiction’s audit may need modifications for another.<\/p>\n <p><strong>Single-source integration vs. multi-vendor assembly.<\/strong> A line built from a single manufacturer’s equipment carries lower integration risk \u2014 filling and sealing parameters are pre-calibrated, service responsibility is consolidated, and commissioning is faster. Multi-vendor lines can offer best-in-class individual machines but shift the integration burden onto the buyer. Weigh this trade-off against both your capex and your timeline.<\/p>\n <p><strong>After-sales support and spare parts.<\/strong> A production line is a multi-year asset. Evaluate warranty terms, technical support availability, and spare part lead times as carefully as you evaluate machine specifications. Levapack, for example, backs its can packaging machines with a 16-month warranty and round-the-clock technical support \u2014 a benchmark worth measuring against.<\/p>\n  <div class=\"bp-cta-end bd-reveal\"> <div class=\"bp-ctaend-icon\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><rect width=\"20\" height=\"16\" x=\"2\" y=\"4\" rx=\"2\"\/><path d=\"m22 7-8.97 5.7a1.94 1.94 0 0 1-2.06 0L2 7\"\/><\/svg> <\/div> <div class=\"bp-cta-end-content\"> <div class=\"bp-cta-end-title\">Discuss Your Production Line Requirements<\/div> <div class=\"bp-cta-end-sub\">Get a tailored equipment recommendation from our packaging engineers.<\/div> <a href=\"https:\/\/www.levapack.com\/it\/contatto\/\" target=\"_self\" class=\"bp-cta-end-btn\">Talk to an Engineer<\/a> <\/div> <\/div>\n <p style=\"margin-top:2em;font-size:14px;color:var(--text-primary);font-style:italic;\">References: ProXES \u2014 Industrial Mayonnaise Processing Plants; IBC MACHINE \u2014 Mayonnaise Production Line; Silverson \u2014 Mayonnaise Manufacturing; Guanyu Mixer \u2014 Mayonnaise Production Line Costs; Foodsure Machines \u2014 Set Up A Mayonnaise Production Line; Levapack \u2014 Custom Can Packaging Line Designs.<\/p>\n <\/article><\/div><\/body><\/html>","protected":false},"excerpt":{"rendered":"<p>Mayonnaise Production Line Guide \u2014 From Emulsification to Finished Package Mayonnaise Production Line Guide \u2014 From Emulsification to Finished Package A mayonnaise production line is not<span class=\"excerpt-hellip\"> [...]<\/span><\/p>","protected":false},"author":1,"featured_media":75738,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"none","_seopress_titles_title":"Mayonnaise Production Line: Build the System Behind Every Smooth Batch","_seopress_titles_desc":"Explore the equipment, processing methods, and packaging options behind a mayonnaise production line\u2014from vacuum emulsification to filling, sealing, and labeling.","_seopress_robots_index":"","footnotes":""},"categories":[181],"tags":[],"class_list":["post-75739","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-mml-blog"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/posts\/75739","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/comments?post=75739"}],"version-history":[{"count":1,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/posts\/75739\/revisions"}],"predecessor-version":[{"id":75743,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/posts\/75739\/revisions\/75743"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/media\/75738"}],"wp:attachment":[{"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/media?parent=75739"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/categories?post=75739"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/tags?post=75739"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}

The emulsifier is the conductor, but miss a single instrument \u2014 the filler, the seamer, the labeler \u2014 and the performance never reaches the audience.<\/p>\n <h2>Core Equipment in a Mayonnaise Production Line<\/h2>\n <p>The equipment you select for each stage turns on three variables: your formula type (full-fat, low-fat, or vegan), your target throughput, and your packaging format. The three workhorses below form the backbone of most lines.<\/p>\n <h3>Vacuum Emulsifier: The Heart of the Line<\/h3>\n <img decoding=\"async\" src=\"https:\/\/www.levapack.com\/wp-content\/uploads\/2026\/08\/mayonnaise-production-line-3.webp\" alt=\"Vacuum Emulsifier\" style=\"width: 512px !important; height: auto !important; display: block !important; margin: 24px auto !important; border-radius: 12px !important; box-shadow: 0 10px 25px rgba(0,0,0,0.15) !important; max-width: 100% !important;\">\n <p>The vacuum emulsifier is the most expensive and most technically demanding single machine on a mayonnaise line. It integrates mixing, high-shear emulsification, vacuum deaeration, and temperature control into one vessel \u2014 and the quality of what happens inside it determines everything downstream.<\/p>\n <p>At its core, a rotor-stator homogenizer spins at tip speeds of 10\u201350 meters per second, shearing the oil phase into micron-scale droplets as it enters the water phase. The vacuum environment \u2014 typically -0.06 to -0.09 MPa \u2014 is not a luxury; it is a functional necessity. Without vacuum, air becomes entrained in the emulsion, causing oxidation, off-flavors, and a shortened shelf life. Oil dosing rate is a critical productivity lever: industrial systems can introduce oil at up to 3 kg\/s without breaking the emulsion.<\/p>\n <p>Commercial emulsifiers range from 100-liter pilot units to 2,000-liter production vessels, built from SUS304 or SUS316L food-grade stainless steel. Key configuration choices include variable-frequency drives for independent control of the anchor agitator and the high-shear head, a triple-layer jacketed tank for heating and cooling, and integrated CIP spray balls for cleaning between batches. A typical emulsification cycle runs 20\u201330 minutes under cold process conditions (5\u201325\u00b0C), after which the mayonnaise is ready for transfer.<\/p>\n  <div class=\"bp-stat-grid bd-reveal\"> <div class=\"bp-stat-grid-header\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M3 3v18h18\"\/><path d=\"m19 9-5 5-4-4-3 3\"\/><\/svg> <span class=\"bp-stat-grid-title\">Mayonnaise by the Numbers<\/span> <\/div> <div class=\"bp-stat-grid-body\"> <div class=\"bp-stat-cell\"> <div class=\"bp-stat-num\">2\u201310 \u03bcm<\/div> <div class=\"bp-stat-label\">Oil Droplet Size<\/div> <\/div> <div class=\"bp-stat-cell\"> <div class=\"bp-stat-num\">10k\u2013100k<\/div> <div class=\"bp-stat-label\">Viscosity (cP)<\/div> <\/div> <div class=\"bp-stat-cell\"> <div class=\"bp-stat-num\">3.5\u20134.2<\/div> <div class=\"bp-stat-label\">pH Range<\/div> <\/div> <div class=\"bp-stat-cell\"> <div class=\"bp-stat-num\">20\u201330<\/div> <div class=\"bp-stat-label\">Cycle Time (min)<\/div> <\/div> <\/div> <\/div>\n <h3>Pasteurization Systems: When and Why You Need One<\/h3>\n <p>Not every mayonnaise line requires a pasteurizer. Traditional full-fat mayonnaise \u2014 with its low pH of 3.5\u20134.2 and high oil content \u2014 is naturally hostile to pathogens like Salmonella and E. coli. The acid does the preserving. What needs pasteurization is the raw egg ingredient, which responsible manufacturers source as pre-pasteurized liquid yolk or egg powder.<\/p>\n <p>Pasteurization at the product stage enters the picture with low-fat and starch-based formulations. These recipes replace some of the oil \u2014 and some of the egg \u2014 with starch and hydrocolloids like xanthan gum. The starch slurry must be cooked to activate its thickening and binding properties. This is where a Scraped Surface Heat Exchanger (SSHE) comes in: the product enters at 20\u201325\u00b0C, is heated to 80\u201390\u00b0C for 3\u20135 minutes, then rapidly cooled back to 5\u201320\u00b0C. The SSHE’s rotating blades prevent the viscous starch mixture from scorching against the hot wall.<\/p>\n <p>The rule of thumb is straightforward: if your recipe relies on egg yolk for emulsification and vinegar for preservation, you are on the cold path. If starch or gum carries part of the functional load, budget for a pasteurizer.<\/p>\n <h3>Filling Machines: Matching Your Packaging Format<\/h3>\n <p>The filling machine is where your packaging decision becomes a hardware decision \u2014 and mayonnaise is an unforgiving product to fill. With a viscosity of 10,000\u2013100,000 centipoise, it is roughly ten thousand times thicker than water. Gravity fillers will not work. Piston fillers are the standard choice for viscous products, delivering volumetric accuracy within \u00b11% at speeds of 20\u201360 containers per minute. Rotary piston fillers handle higher throughputs; servo-driven models offer recipe memory and quick changeover between container sizes.<\/p>\n <p>The filling head design must also account for mayonnaise’s thixotropic behavior \u2014 it thins under shear and thickens at rest. The filler exploits this by keeping the product under shear during dispensing, then allowing it to set inside the container. Filling temperature is held at 5\u201325\u00b0C; any warmer and the emulsion risks destabilizing.<\/p>\n <h2>From Emulsion to Package: Filling and Sealing Integration<\/h2>\n <p>Here is something the industry rarely discusses openly: most content about mayonnaise production lines stops at the emulsifier. Search for “mayonnaise production line” and you will find pages of detail about rotor-stator geometry, oil droplet distribution, and vacuum levels. Then, almost as an afterthought, a single sentence: “The product is then filled and packaged.”<\/p>\n <p>That sentence hides half the line \u2014 and arguably the half where more quality failures start.<\/p>\n <h3>Filling Systems for Viscous Products: Getting Mayo into the Container<\/h3>\n <img decoding=\"async\" src=\"https:\/\/www.levapack.com\/wp-content\/uploads\/2026\/08\/mayonnaise-production-line-1.webp\" alt=\"Filling Systems for Viscous Products\" style=\"width: 512px !important; height: auto !important; display: block !important; margin: 24px auto !important; border-radius: 12px !important; box-shadow: 0 10px 25px rgba(0,0,0,0.15) !important; max-width: 100% !important;\">\n <p>Mayonnaise does not pour. It does not flow predictably. It must be pushed, metered, and placed \u2014 and once inside the container, it must be sealed before oxygen can begin its work.<\/p>\n <p>The choice of filler type depends on container format and line speed. Piston fillers dominate for jars, bottles, and cans, offering the displacement precision needed for thick emulsions. For flexible pouches and sachets, vertical form-fill-seal machines integrate filling and sealing into a continuous motion. Net-weight fillers, which use load cells under each filling station, provide the highest accuracy for premium products where overfill represents real cost.<\/p>\n <p>A frequently overlooked consideration is the physical distance between the filler and the sealer. Mayonnaise begins oxidizing the moment it leaves the vacuum environment of the emulsifier. The shorter the conveyor between filling and sealing, the less oxygen exposure \u2014 and the longer the shelf life. In a well-designed line, filling and sealing stations sit within a few meters of each other on the same conveyor.<\/p>\n  <div class=\"bp-insight bd-reveal\"> <div class=\"bp-insight-body\"> <div class=\"bp-insight-headline\">The shorter the distance between filler and sealer, the longer the shelf life.<\/div> <div class=\"bp-insight-sub\">In a well-designed line, filling and sealing stations sit within a few meters of each other on the same conveyor \u2014 minimizing oxygen exposure from the moment the emulsion leaves vacuum.<\/div> <\/div> <div class=\"bp-insight-icon\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M15 14c.2-1 .7-1.7 1.5-2.5 1-.9 1.5-2.2 1.5-3.5A6 6 0 0 0 6 8c0 1 .2 2.2 1.5 3.5.7.7 1.3 1.5 1.5 2.5\"\/><path d=\"M9 18h6\"\/><path d=\"M10 22h4\"\/><\/svg> <\/div> <\/div>\n <h3>Sealing and Closure Systems: The Shelf-Life Gatekeeper<\/h3>\n <p>A mayonnaise jar that leaks \u2014 or worse, one that does not visibly leak but lets in enough oxygen to turn the surface rancid within weeks \u2014 is a recall in the making. The sealing system is the last machine to touch the product before it reaches the consumer.<\/p>\n <p>For glass jars, the standard is a screw capper applying metal or plastic lug caps at a controlled torque \u2014 typically 0.5\u20131.5 N\u00b7m for a standard 28 mm finish. Many lines add an aluminum foil induction sealer before capping: an electromagnetic field heats a foil laminate bonded to the jar rim, creating a hermetic barrier that doubles as tamper evidence.<\/p>\n <p>PET bottles and jars follow a similar pattern \u2014 foil induction seal plus screw cap \u2014 but require tighter process control because plastic threads deform more easily under torque. For metal cans, the closure technology is fundamentally different: a double-seam seamer rolls the can body flange and lid curl together into an interlocking fold. Seam integrity is measured by three parameters: seam width (1.25\u20131.45 mm), seam thickness (1.50\u20131.70 mm), and body hook overlap (\u226555%). A single seam that falls outside these tolerances can fail weeks after shipping \u2014 and by then, the entire batch is at risk.<\/p>\n <p>Flexible pouches use heat sealing, with jaw temperature, dwell time, and pressure calibrated to the specific film laminate. The common failure mode here is seal contamination: a droplet of mayonnaise on the sealing area prevents proper fusion, creating a weak point that bursts under transport pressure.<\/p>\n <h2>Can Packaging for Mayonnaise: What Production Managers Need to Know<\/h2>\n <p>Metal can packaging for mayonnaise occupies an interesting position in the market. It is not the dominant format \u2014 glass jars and PET bottles own most retail shelf space. But for export markets, foodservice, and premium gift packaging, cans offer distinct advantages: zero light transmission (no photo-oxidation), excellent oxygen barrier, no breakage risk in transit, and ambient-temperature storage without refrigeration.<\/p>\n <p>If you are considering can packaging for your mayonnaise line, the engineering requirements differ meaningfully from jar and bottle lines.<\/p>\n <h3>Can Types, Lining, and Seam Integrity for Mayo<\/h3>\n  <div class=\"bp-compare bd-reveal\"> <div class=\"bp-compare-grid\"> <div class=\"bp-compare-col\"> <div

products corrode bare metal. Every can destined for mayonnaise must carry an internal lacquer coating, typically epoxy or phenolic resin, applied at 6\u201310 grams per square meter. Without it, the product attacks the tinplate or aluminum, leaching metallic ions into the emulsion and discoloring the surface.<\/p>\n <p>Double-seam quality control deserves special emphasis in a mayonnaise line. Unlike a screw cap that you can inspect visually for cross-threading, a double seam hides its defects inside a folded metal structure. Production managers should budget for a seam inspection station \u2014 either a manual tear-down rig with a seam micrometer, or an automated vision system for higher-speed lines \u2014 and implement a sampling schedule (typically one can per seamer head per hour). The cost of this inspection is trivial compared to the cost of recalling a container shipment where 5% of the seams failed.<\/p>\n  <div class=\"bp-checklist bd-reveal\"> <div class=\"bp-checklist-title\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M12 22s8-4 8-10V5l-8-3-8 3v7c0 6 8 10 8 10z\"\/><\/svg> Seam Inspection Rule <\/div> <div class=\"bp-checklist-row\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M22 11.08V12a10 10 0 1 1-5.93-9.14\"\/><path d=\"m9 11 3 3L22 4\"\/><\/svg> Manual tear-down rig with seam micrometer, or automated vision system <\/div> <div class=\"bp-checklist-row\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M22 11.08V12a10 10 0 1 1-5.93-9.14\"\/><path d=\"m9 11 3 3L22 4\"\/><\/svg> Measure all three parameters: width (1.25\u20131.45 mm), thickness (1.50\u20131.70 mm), overlap (\u226555%) <\/div> <div class=\"bp-checklist-row\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"M22 11.08V12a10 10 0 1 1-5.93-9.14\"\/><path d=\"m9 11 3 3L22 4\"\/><\/svg> Sample one can per seamer head per hour \u2014 every hour the line runs <\/div> <\/div>\n <h3>Vacuum Sealing and Nitrogen Flushing for Extended Shelf Life<\/h3>\n <p>Even a perfectly seamed can contains oxygen in its headspace \u2014 and oxygen is what turns oils rancid. Two methods address this. Vacuum sealing draws a negative pressure (-0.04 to -0.06 MPa) inside the can immediately before the seamer closes it, reducing the oxygen available for oxidation. Nitrogen flushing goes further: a jet of food-grade nitrogen (purity \u226599.5%) displaces the headspace atmosphere before sealing, pushing residual oxygen below 3% \u2014 and in high-end lines, below 1%.<\/p>\n <p>For mayonnaise, nitrogen flushing matters most when the formulation includes unsaturated oils \u2014 sunflower, rapeseed \u2014 that oxidize faster. The incremental equipment cost is modest next to the shelf-life gain: a product that might show rancidity at six months in a standard-sealed can can reach twelve months or more with nitrogen flushing.<\/p>\n <p><em>Most filling equipment suppliers focus on one stage \u2014 either the filler or the seamer \u2014 but few offer an integrated solution that covers both. For production managers evaluating can packaging for viscous products like mayonnaise, suppliers such as Levapack provide custom can filling and seaming lines that combine servo-driven piston fillers with vacuum and nitrogen-flush double seamers, configurable for tinplate, aluminum, or composite cans at speeds from 20 to 60 containers per minute. The advantage of a single-source line is that filling and sealing parameters are calibrated together, eliminating the integration risk of matching equipment from separate manufacturers.<\/em><\/p>\n  <div class=\"bp-cta-mid bd-reveal\"> <div class=\"bp-ctamid-icon\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><path d=\"m22 2-7 20-4-9-9-4Z\"\/><path d=\"M22 2 11 13\"\/><\/svg> <\/div> <div class=\"bp-cta-mid-content\"> <div class=\"bp-cta-mid-text\">Need a custom can packaging line configured for your product?

Hot processing makes economic sense when the business model depends on lower raw material cost \u2014 starch is cheaper than egg yolk \u2014 or when the target market demands low-fat variants.<\/p>\n <h2>Key Factors When Investing in a Mayonnaise Production Line<\/h2>\n <p>By this point, the technical landscape should be clear. What remains is the commercial checklist \u2014 the questions to answer before you send a request for quotation.<\/p>\n <p><strong>Target throughput.<\/strong> A small-scale line producing 500 kg per day needs fundamentally different equipment than a 5,000-liter-per-hour industrial plant. Define your daily or hourly target before comparing machine specs. A line that is undersized on day one constrains growth; a line that is oversized wastes capital and floor space.<\/p>\n <p><strong>Formula type.<\/strong> Full-fat, low-fat, vegan, flavored \u2014 each pulls a different set of equipment. A full-fat line skips the pasteurizer. A low-fat line needs one. A vegan line replaces egg with plant-based lecithin, which may require adjustments to the emulsifier’s shear profile.<\/p>\n <p><strong>Packaging format.<\/strong> Glass jars, PET bottles, metal cans, or flexible pouches \u2014 the decision dictates your filler type, your sealer or capper, and your labeling system. It also affects shelf life, shipping cost, and retail positioning. Make this decision before you buy any equipment.<\/p>\n <p><strong>Target market regulations.<\/strong> FDA, EU, and export-market food safety standards impose different requirements on material traceability, CIP validation, and allergen control. Equipment that passes one jurisdiction’s audit may need modifications for another.<\/p>\n <p><strong>Single-source integration vs. multi-vendor assembly.<\/strong> A line built from a single manufacturer’s equipment carries lower integration risk \u2014 filling and sealing parameters are pre-calibrated, service responsibility is consolidated, and commissioning is faster. Multi-vendor lines can offer best-in-class individual machines but shift the integration burden onto the buyer. Weigh this trade-off against both your capex and your timeline.<\/p>\n <p><strong>After-sales support and spare parts.<\/strong> A production line is a multi-year asset. Evaluate warranty terms, technical support availability, and spare part lead times as carefully as you evaluate machine specifications. Levapack, for example, backs its can packaging machines with a 16-month warranty and round-the-clock technical support \u2014 a benchmark worth measuring against.<\/p>\n  <div class=\"bp-cta-end bd-reveal\"> <div class=\"bp-ctaend-icon\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"><rect width=\"20\" height=\"16\" x=\"2\" y=\"4\" rx=\"2\"\/><path d=\"m22 7-8.97 5.7a1.94 1.94 0 0 1-2.06 0L2 7\"\/><\/svg> <\/div> <div class=\"bp-cta-end-content\"> <div class=\"bp-cta-end-title\">Discuss Your Production Line Requirements<\/div> <div class=\"bp-cta-end-sub\">Get a tailored equipment recommendation from our packaging engineers.<\/div> <a href=\"https:\/\/www.levapack.com\/it\/contatto\/\" target=\"_self\" class=\"bp-cta-end-btn\">Talk to an Engineer<\/a> <\/div> <\/div>\n <p style=\"margin-top:2em;font-size:14px;color:var(--text-primary);font-style:italic;\">References: ProXES \u2014 Industrial Mayonnaise Processing Plants; IBC MACHINE \u2014 Mayonnaise Production Line; Silverson \u2014 Mayonnaise Manufacturing; Guanyu Mixer \u2014 Mayonnaise Production Line Costs; Foodsure Machines \u2014 Set Up A Mayonnaise Production Line; Levapack \u2014 Custom Can Packaging Line Designs.<\/p>\n <\/article><\/div><\/body><\/html>","protected":false},"excerpt":{"rendered":"<p>Mayonnaise Production Line Guide \u2014 From Emulsification to Finished Package Mayonnaise Production Line Guide \u2014 From Emulsification to Finished Package A mayonnaise production line is not<span class=\"excerpt-hellip\"> [...]<\/span><\/p>","protected":false},"author":1,"featured_media":75738,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"none","_seopress_titles_title":"Mayonnaise Production Line: Build the System Behind Every Smooth Batch","_seopress_titles_desc":"Explore the equipment, processing methods, and packaging options behind a mayonnaise production line\u2014from vacuum emulsification to filling, sealing, and labeling.","_seopress_robots_index":"","footnotes":""},"categories":[181],"tags":[],"class_list":["post-75739","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-mml-blog"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/posts\/75739","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/comments?post=75739"}],"version-history":[{"count":1,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/posts\/75739\/revisions"}],"predecessor-version":[{"id":75743,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/posts\/75739\/revisions\/75743"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/media\/75738"}],"wp:attachment":[{"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/media?parent=75739"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/categories?post=75739"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.levapack.com\/it\/wp-json\/wp\/v2\/tags?post=75739"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
