I. Core Materials and Characteristics
PU (Polyurethane) : Mainstream material, in compliance with FDA food certification, non-toxic and odorless, oil-resistant, wear-resistant, cut-resistant, with good low-temperature toughness (-40℃), easy to clean, suitable for meat, baked goods, and frozen foods.
PVC (polyvinyl chloride) : It has a low cost, a smooth surface, and can withstand temperatures ranging from -10 ℃ to 80℃. It is suitable for fruits, vegetables, and packaged foods, but its oil resistance and low-temperature resistance are relatively weak.
Silicone rubber: Heat-resistant (-60℃ to 200℃), non-stick, suitable for baking and high-temperature steaming scenarios.
PE (Polyethylene) : Chemically stable, resistant to acids and alkalis, used for the transportation of beverages and dairy products.
Teflon (PTFE) : Ultimate anti-sticking and high-temperature resistance, suitable for high-adhesion and high-temperature materials (such as chocolate, sugar coating).
Ii. Key Performance Requirements
Safety and compliance: The materials must be non-toxic and non-migratory, and meet food contact standards such as FDA and EU 10/2011 of the European Union.
Hygienic and easy to clean: Smooth surface without pores, seamless joints, washable/high-pressure rinsible, corrosion-resistant, and less prone to bacterial growth.
Mechanical properties: High tensile strength, flex resistance, anti-aging, smooth operation without deviation, suitable for high-speed and turning transportation.
Environmental resistance: Heat resistance, oil resistance, acid and alkali resistance, anti-slip, anti-stick, suitable for freezing, cooking, oil stains and other working conditions.
Iii. Common Structures and Customization
Basic structure: Surface layer (food-grade coating) + skeleton layer (polyester fabric, providing strength) + bottom layer (anti-friction, anti-static).
Customization options
Patterns: Anti-slip and anti-stick (such as rhombus, grid, gauze pattern).
Attachments: Skirt, baffle, partition (leak-proof, large-inclination conveying).
Color: White (general), blue (aquatic products/fruits and vegetables), green (baking), etc.
Size: Width, thickness and length can be customized as required.
Iv. Precautions for Use and Maintenance
(1) Installation and Commissioning
The roller is calibrated in parallel with a moderate tension (if it is too tight, the wear will be large; if it is too loose, it is prone to deviation and slippage).
The joint is seamless and smooth. Hot vulcanization or high-frequency welding is preferred to avoid material accumulation and fracture.
The idlers and frames should be clean and free of burrs to prevent the belts from being scratched.
(2) Daily cleaning
Before work: Wipe the surface clean of dust and impurities with a dry cloth.
After work: Clean the residue and oil stains with warm water and food-grade neutral detergent, then rinse with clean water and dry. Do not use strong acids, strong alkalis, wire brushes or high-pressure direct injection into the joints.
Regular: Conduct a deep cleaning weekly, inspect the joints and wear, and maintain with food-grade silicon-based anti-sticking agent.
(3) Operation Management
Overloading and starting with materials are strictly prohibited. Avoid scratches from sharp objects.
Control the ambient temperature (PU: -20℃ to 80℃), and keep away from heat sources (≥1 meter).
If the deviation occurs, adjust the roller or tensioning in time. Repair any minor damage immediately to prevent it from expanding.
(4) Storage
After cleaning, roll it up and place it in a dry and well-ventilated area with a temperature ranging from -18 ℃ to 40℃ and a humidity of 50% to 80%. Protect it from direct sunlight, rain, acids, alkalis and oil stains. Turn it over once every season.
V. Selection Suggestions
Select the material by material:
Meat/oil stains → PU (oil-resistant).
Baking/high temperature → Silicone rubber or PU high-temperature resistant type.
Fruits and vegetables/beverages → PVC or PU (water-resistant).
High viscosity/sugar coating → Teflon or PU anti-stick pattern.
Select the structure according to the working conditions
Large inclination Angle/leak-proof → Add skirt and baffle.
High-speed/turning → High-strength polyester frame, seamless joints.
Priority compliance certification: Request FDA and EU food contact certificates to ensure material safety.
