In the food processing industry, each stage has different conveyor belt needs. From raw material transport to finished product packaging and shipping, the belt must meet hygiene, safety, temperature resistance, and efficiency standards. The following explains each stage and gives material selection suggestions.

Raw Material Transportation

Purpose: Move raw materials like flour, sugar, oil, fruits, and vegetables from warehouses or storage tanks to steps such as mixing, blending, and crushing.
Requirements: Non-toxic, oil-resistant, easy to clean, and compliant with food hygiene standards (e.g., US FDA).

Optional Belts:
PU Belts: Direct food contact, oil-resistant, hydrolysis-resistant, cut-resistant, used in high-sanitation environments.
PE Belts: Cold-resistant (down to -400C), corrosion-resistant, FDA-compliant, used in tobacco and high-temperature food environments.

Cleaning and Disinfection
Purpose: Move raw or semi-finished products to cleaning and disinfection equipment.
Requirements: Smooth, crack-free, easy to clean, resistant to disinfectants.

Optional Belts:
Silicone Belts: Anti-stick, corrosion-resistant, good for frequent cleaning.

Cutting and Mixing

Purpose: Cut and mix raw materials on the belt.
Requirements: Smooth, residue-free, non-slip, no contamination.

Optional Belts:
PU Belts: Cut-resistant, easy to clean, good for bread, candy, and similar processing.

Cooking
Purpose: Move ingredients to steaming, baking, or frying.
Requirements: High-temperature resistance (over 120°C), anti-stick, easy to clean.

Optional Belts:
Silicone Belts: Resistant to -60°C to 250°C, good for sticky foods like dough and chocolate.

Packaging
Purpose: Move finished products to the packaging machine.
Requirements: Choose belt type based on food (e.g., seafood, snacks) to keep product intact.

Optional Belts:
PE Belts: Flexible, good for high-speed packaging lines.
PVC Belts: Low cost, durable, good for lightweight packaging.

Storage and Distribution
Requirements: Belts are not used directly, but selection must ensure hygiene throughout the process to avoid contamination (like plasticizer migration).

General Standards for Food-Grade Conveyor Belts
Material Safety: No organic solvents, toxic, or hazardous metals.
Surface: Smooth, no cracks, no dirt buildup.
Temperature: Prevent spoilage at high heat.
Cleanliness: No dirt or water stains on contact surfaces, reduce cross-contamination.
Friction: Low, to keep conveying efficient.

Comparison of material properties

Type	Features	Application Scenarios
PVC	Strong weather resistance, low cost	Lightweight packaging
PU	Oil-resistant, cut-resistant, suitable for direct food contact	Baking, meat processing
PE	High temperature resistance, non-toxic, non-flammable	Tobacco, high-temperature food transportation
Silicone	High temperature resistance, anti-stick	Bread, candy, and other high-viscosity foods
