Hygienic Conveyor
Food-grade conveyors that move product between machines, lift it where needed and keep each section of the line running at a matched pace.

Short answer: A hygienic conveyor moves food between processing steps, lifts it where machines sit at different heights and evens out the flow so each machine gets product at the right pace. The configuration depends on the product (fragile, sticky, wet, dusty), the height difference to overcome, and how the line will be cleaned.
How it works
A conveyor consists of a frame, a carrying element (belt, modules, buckets or a screw), a drive with speed control and the transfer points at each end. Product is loaded from a hopper, chute or the previous machine, carried along or up, and discharged into the next step. Side guides, flights and cleats keep product in place on inclines. Speed control lets operators match the rate to upstream and downstream machines, and sensors can stop or slow the conveyor when a buffer is full.
Hygienic design is mainly about access: frames that leave space to clean underneath, belts that can be lifted or removed without tools, and surfaces that let water and debris run off rather than collect. For wet areas, motors and bearings are placed or protected so that washdown water does not reach them.
Which configuration fits
| Form | Suits | Watch out for |
|---|---|---|
| Flat belt | Packs, dough, sorting tables | Sticky products may need special belt surfaces |
| Modular plastic belt | Wet, oily, frozen products, inclines | Hinges need attention during cleaning |
| Bucket elevator | Snacks, nuts, grains to weighers | Fragile products: gentle filling and discharge |
| Screw conveyor | Powders, grains, pastes | Enclosed; plan access for cleaning |
What we need from you to quote
- Product, piece size, temperature and how it behaves (sticky, fragile, dusty)

Where it sits in a line
Conveyors connect most equipment on this site, such as raising product to a multihead weigher, linking a continuous fryer to seasoning, or feeding a food freezer. In packing areas they carry packs through an in-line checkweigher and food metal detector.
Common configurations
- Option A
Flat belt
a continuous PU or PVC belt for packs, dough pieces and inspection or sorting tables.
- Option B
Modular plastic belt
interlocking plastic modules for wet, oily or frozen products and inclines with flights.
- Option C
Bucket elevator
buckets on a chain or belt lift snacks, nuts or grains vertically to weighers or silos.
- Option D
Screw conveyor
an enclosed screw moves powders, grains or pastes horizontally or at an angle.

Frequently asked questions
Which belt type should I use?
Flat belts suit dry, packed or delicate products and are smooth to clean. Modular plastic belts handle wet, oily and frozen products and steep inclines. Bucket elevators and screws suit bulk solids and powders. Product behaviour and cleaning method decide the choice.
Why does conveying cause product breakage?
Drops between belts, sharp direction changes and speeds that do not match the next machine cause most damage. Short transfer points, gentle inclines and buffer sections reduce breakage, especially for chips, crackers and fried snacks.
How are conveyors cleaned?
Hygienic designs use open frames, few horizontal ledges, tension release for lifting the belt and sloped surfaces that let water run off. Some include belt-washing stations. Tell us your cleaning routine so the design supports it.
