Food conveyor and material handling — system overview
Conveyors and material handling systems link individual machines in a food processing line, moving product between processing stages. The appropriate conveyor type depends on the product characteristics (size, shape, fragility, temperature, stickiness), the required transfer speed and direction (horizontal, inclined, vertical), and the hygiene requirements of the application. The main types include: flat belt conveyors (general-purpose product transport; product-contact belts in PU or PVC food-grade material); modular belt conveyors (plastic interlocking belt segments — easier to clean, maintain, and modify than flat belts; suitable for washdown environments); screw conveyors (enclosed rotating screw inside a tube or trough — for powders, granules, and pumpable food materials; protects product from contamination); bucket elevators (vertical elevation of product in enclosed buckets — for fragile products or where product must be handled gently during vertical transport; also used for bulk grain, sugar, and other solid raw materials); vibratory feeders and conveyors (electrically driven vibration moves product along a trough — gentle, can be used for fragile or irregular products, also for controlled feeding and metering); and pneumatic conveying systems (product is transported in an air stream through pipes — for powders, granules, and small pieces; positive-pressure or vacuum systems available). In food processing, all food-contact conveyor surfaces must be constructed from materials approved for food contact.
Frequently asked questions
What belt material should I specify for food-contact conveyor belts?
Food-contact conveyor belts must be made from materials approved for food contact under the relevant regulations for your target market (EU Regulation 10/2011 on plastic food contact materials; US FDA 21 CFR Part 177; or equivalent). Common food-grade belt materials include: polyurethane (PU) — the most widely used for food-contact flat belts; PVC (food-grade formulation, increasingly restricted in some markets due to plasticiser concerns); thermoplastic polyester (PET); polyolefins (polyethylene, polypropylene); and modular polypropylene or polyethylene interlocked belts. For raw meat and fish applications, look for smooth, continuous surfaces that minimise bacterial harbouring; for high-temperature applications (oven conveyors), fabric-reinforced silicone or PTFE belt materials may be required. Ask suppliers to confirm the regulatory compliance of the belt materials for your target market.
When is a pneumatic conveying system preferable to a mechanical conveyor?
Pneumatic conveying is typically preferred for powders and fine granules (flour, starch, sugar, milk powder, instant coffee, spice powders) where dust containment is important, where the product must be conveyed over long distances or around bends (pipes are more flexible in routing than mechanical conveyors), and where hygiene and closed-system handling are required. Pneumatic systems are harder to clean than mechanical conveyors if product changes or allergen management cleans are required — wash-through cleaning cycles or dedicated lines may be needed. Mechanical screw conveyors or bucket elevators are generally preferable for fragile products that would break up in a pneumatic air stream, and for coarse or abrasive materials that would cause excessive pipe wear. Discuss the product characteristics and production flexibility requirements with the supplier when selecting between pneumatic and mechanical conveying options.
