Each stage carries its own requirements, and the versatility of the plastic modular belt platform means that a single product family can satisfy all of them with appropriate variant selection. The following stage-by-stage breakdown reflects real-world application experience in UK snack manufacturing environments.<\/p>\n \n \n \u2460 Raw Ingredient In-Feed<\/h3>\nPotatoes, maize grits, and raw nuts arrive at the in-feed stage covered in moisture, soil residues, and irregular shapes. A flush-grid or raised-rib plastic modular conveyor belt with high open-area percentage (38\u201352%) provides drainage while the positive-drive sprocket system delivers consistent speed control essential for feeding slicers and extruders at accurate rates. The belt’s stiffness prevents sagging under bulk loads, while polypropylene’s chemical resistance handles potato starches and enzyme cleaners without swelling or degradation.<\/p>\n<\/div>\n \n \u2461 Fryer Exit and Thermal Transfer<\/h3>\nContinuous fryers operate at oil temperatures of 160\u2013185 \u00b0C, and product exiting a fryer belt still carries residual heat of 100 \u00b0C or above. The post-fryer transfer conveyor must handle this thermal load without belt elongation or module distortion. Food-grade polypropylene with stabiliser additives retains its mechanical properties at sustained temperatures up to 120 \u00b0C, making a plastic modular belt in PP the standard choice at this critical transfer point. A perforated flat-top design here allows excess oil to drain back into the fryer collection tray, reducing product greasiness and improving yield at the checkweigher.<\/p>\n<\/div>\n \n \u2462 Seasoning Drum and Coating<\/h3>\nAfter frying or baking, snacks enter rotary seasoning drums where powdered flavours \u2014 salt, vinegar, paprika, cheese powder \u2014 are applied. The in-feed and discharge conveyors of these drums operate in environments saturated with fine flavour dust and adhesive oil mists. A plastic modular belt with closed-top surface prevents powder accumulation between modules, while the material’s non-reactive chemistry ensures that acidic flavour compounds (vinegar, citric acid) cause no belt degradation over extended production campaigns. Maintenance teams report that flat-top PP belts in seasoning areas last up to 40% longer than the fabric alternatives previously installed.<\/p>\n<\/div>\n \n \u2463 Cooling Tunnel and Air-Blast Zones<\/h3>\nSnacks must reach a stable low temperature before packaging to prevent moisture migration inside sealed bags. Cooling tunnels use forced-air or refrigerated air-blast systems that blow cold air through the product bed. A perforated plastic modular conveyor belt with 35\u201350% open area allows maximum air circulation both above and below the product, reducing cooling dwell time and enabling faster line speeds. Because PP is dimensionally stable across both hot and cold temperature excursions, the same belt specification used on the fryer exit can traverse the cooling tunnel without re-tensioning adjustments, simplifying maintenance planning.<\/p>\n<\/div>\n \n \u2464 Checkweigher and Metal Detection Infeed<\/h3>\nRegulatory compliance and retailer specifications require every snack pack to pass through a checkweigher and metal detector before release. These machines demand ultra-precise, vibration-free product presentation. Acetal (POM) plastic modular belt modules, with their superior dimensional consistency and low coefficient of friction, provide the smooth, controlled product transfer these inspection machines require. Critically, acetal is non-magnetic and has low metallic content, minimising false-positive metal detector triggers that disrupt production flow and generate unnecessary waste rejection.<\/p>\n<\/div>\n \n \u2465 Packaging Machine Accumulation<\/h3>\nBefore vertical form-fill-seal (VFFS) or multihead weigher in-feed, snacks are accumulated in a buffer zone to absorb speed differentials between upstream processing and downstream packaging. Side-flexing plastic modular belt configurations allow curved accumulation tables to be built within a minimal factory footprint \u2014 a significant advantage in UK snack facilities where floor space carries a high premium. The modular architecture allows conveyor width to be varied at the table exit to match the multihead weigher bucket geometry precisely, reducing broken product and improving fill accuracy.<\/p>\n<\/div>\n<\/div>\n<\/div>\n <\/p>\n \n Customer Success: Northern England Crisps Manufacturer<\/h2>\nReal-world installation results from a Yorkshire-based snack food producer<\/p>\n <\/p>\n \n \n \n +23%<\/div>\n Line OEE Improvement<\/div>\n<\/div>\n \n -68%<\/div>\n Unplanned Belt Downtime<\/div>\n<\/div>\n \n 14 mo<\/div>\n ROI Payback Period<\/div>\n<\/div>\n \n 3 lines<\/div>\n Converted in 6 Months<\/div>\n<\/div>\n<\/div>\n A mid-sized crisps manufacturer based in West Yorkshire, supplying own-label product to three major UK retail chains, was experiencing persistent belt failures across their two-fryer production facility. The existing woven wire conveyor belts on the post-fryer transfer sections were failing every 8\u201312 weeks due to oil-impregnated wire fatigue, requiring full line shutdowns of 4\u20136 hours per replacement. Each shutdown event was costing an estimated \u00a311,000 in lost production value. The maintenance team was also spending approximately 30 hours per month on belt tension adjustments and hygiene audit remedial actions related to wire belt harborage points.<\/p>\n Ever Power specified PP flat-top plastic modular belts with 38 mm pitch for the fryer exit and post-fryer transfer sections, and perforated PP modular belts for the cooling tunnel. Within the first 90 days, unplanned stoppages attributable to conveyor belt failure dropped by 68%. The site’s BRCGS audit score for conveyor hygiene improved from a ‘C’ observation to zero hygiene-related non-conformances. The total project cost was recovered within 14 months, and the site has since converted a third production line to the same plastic modular belt platform.<\/p>\n<\/div>\n <\/p>\n \n \n “We used to dread fryer belt change days. With the Ever Power plastic modular belt, one person can replace a damaged section during a scheduled break. The whole team’s attitude to maintenance has shifted because it’s no longer a crisis event.”<\/p>\n \u2014 Engineering Manager<\/div>\n West Yorkshire Crisps Producer, UK<\/div>\n<\/div>\n \n “The hygiene performance of the plastic modular conveyor belt system was immediately obvious at our next BRC audit. The auditor specifically noted the open-hinge design as best practice for preventing oil residue accumulation. It directly contributed to our Grade A certification.”<\/p>\n \u2014 Quality Assurance Director<\/div>\n Peanut Snack Manufacturer, East Midlands, UK<\/div>\n<\/div>\n \n “We specified Ever Power modular belts across our new extruded snack line in Scotland. The lead time for custom-width belt sections was shorter than any other supplier we evaluated, and the technical support during commissioning was genuinely impressive. We haven’t had a single belt-related downtime event in 18 months of operation.”<\/p>\n |
