Huayi Smart Equipment designs commercial kitchen and food processing equipment for overseas buyers who need conveyors that actually fit production, cleaning, and maintenance work. A conveyor looks harmless on a quotation sheet. On site, it decides line speed, drainage, operator reach, and whether the sanitation team can finish cleaning before the next shift.
I have seen good washing machines and cutters lose capacity because the connecting conveyor was treated as an accessory. The belt was too narrow for wet vegetables. The motor sat in the spray zone. The transfer height forced workers to lift trays by hand. After two weeks, the plant manager was not complaining about the main machine. He was complaining about the conveyor between machines.
Start with product, capacity, and cleaning method. Leafy vegetables, frozen dumplings, raw meat, bakery trays, and packaged meals do not need the same conveyor. A wet vegetable line may need a perforated modular belt, drip collection, and side guards. A bakery cooling line may need open mesh, low belt tension, and airflow clearance. A packing conveyor may need stable side pressure and a working height around 850 mm to 950 mm.
Huayi Smart Equipment usually asks for target output in kg/h or packs/min, product size, product temperature, belt width, available floor length, washdown frequency, and voltage. A 600 kg/h vegetable line and a 60 packs/min ready meal line can both use stainless conveyors, but their belt speed, drainage, and operator positions are different.
Conveyor design should be checked together with washing, cutting, cooling, inspection, and packing equipment.
Belt material is not just a catalogue choice. PU belts are common for dry or lightly wet food contact work because they are smooth and support routine wipe-down cleaning. Modular plastic belts are better when drainage, curves, or sprocket drive are needed. Stainless mesh belts fit hot, oily, or oven-related sections, but they need careful edge control and cleaning access.
For direct food contact, buyers should ask for FDA food-contact declaration or EU 1935/2004 documentation where applicable. For equipment sanitation, NSF/ANSI 2-2025 is often used for food equipment construction principles, while EN 1672-2:2025 is useful for hygiene design of food machinery. The practical inspection is simpler: no fabric edge exposed, no cracked flights, no hidden screw pockets, and no dead zone under the return belt.
A conveyor with a 400 mm belt can look fine in a video, then fail with real product. If sliced vegetables spread after washing, the useful belt width may fall to 300 mm. If the line needs 800 kg/h and the product bed depth should stay below 60 mm, belt width and speed must be calculated before ordering. For many inspection sections, practical belt speed sits around 3 m/min to 12 m/min so workers can see defects.
Transfer points need the same attention. A height gap above 80 mm can bruise soft fruit or flip small packs. A poorly matched discharge chute can pile product at one side and overload the next machine. Huayi Smart Equipment checks transfer height, drop distance, guide rail shape, and belt overlap before final layout, especially on washing, cutting, blanching, cooling, and packing lines.
Food conveyors should drain, not hold water. The frame should avoid flat horizontal shelves where foam and product residue stay after cleaning. For wet rooms, the conveyor frame usually needs 304 stainless steel, sloped surfaces, sealed bearings or protected bearing housings, and tool-free belt lifting where possible. Floor clearance should allow cleaning under the conveyor; 150 mm clearance is a useful minimum in many plants.
Washdown motors and electrical parts must match the environment. A dry packing room may accept lower protection, but a vegetable washing area or meat room usually needs IP65 or higher, with cable entries away from direct spray. The sanitation team should be able to remove guards, open return rollers, and inspect the underside without fighting the machine.
Conveyors often cross hygiene zones. That is where mistakes become expensive. Raw material conveyors should not pass over ready-to-eat product. Waste belts should not run next to clean product without physical separation. Where cooked or washed product moves forward, the line should reduce hand contact and avoid splash from floor drains or raw-side traffic.
ISO 14159:2025 gives hygiene requirements for machinery design, and ISO 13857:2019 remains useful for safety distance checks around moving parts. A food conveyor should therefore be checked for both hygiene and guarding. Fingers should not reach nip points, but guards should still be removable for cleaning. If safety and cleaning fight each other, operators will remove the guard and leave it off.
Good conveyor integration reduces product damage, cleaning time, and manual handling between process steps.
A useful RFQ should state product name, product size, product temperature, moisture level, target capacity, belt width, belt speed range, loading method, discharge height, working height, room temperature, cleaning chemical, and available utilities. For example: washed leafy vegetables, 600 kg/h, belt width 600 mm, speed 3 m/min to 10 m/min, working height 900 mm, daily foam cleaning, 380 V three-phase, wet room, IP65 motor.
The RFQ should also ask for frame drawings, belt material certificates, bearing type, motor power, emergency stop positions, drain pan design, spare belt list, and recommended cleaning procedure. These items look boring, but they prevent the common export problem: the conveyor arrives, runs well for one day, then becomes the dirtiest and hardest-to-clean part of the line.
Belt width should be based on product spread, bed depth, and capacity. A nominal 400 mm belt may only give 300 mm useful width for wet vegetables. Buyers should calculate kg/h, product thickness, and belt speed before confirming the frame.
Modular plastic belts are often better for wet, draining, or curved sections. PU belts are useful for smooth direct-contact work. Stainless mesh belts fit hot or oily sections. The right answer depends on product moisture, temperature, cleaning method, and transfer design.
NSF/ANSI 2-2025, EN 1672-2:2025, ISO 14159:2025, and ISO 13857:2019 are useful references for hygiene, food equipment construction, and safety distance checks. Buyers should also apply local electrical and food-contact material rules.
Cleaning access decides daily sanitation time. If the return belt, bearings, and underside cannot be inspected, product residue will stay after washdown. Tool-free lifting, sloped frame surfaces, and 150 mm floor clearance make a real difference.
A food conveyor is not a filler item between two larger machines. It controls product handling, cleaning time, safety guarding, and the true rhythm of the line. For more food processing equipment references and export project support, visit smarthuayi.com.
