The selection of the best conveyor belt for cookies requires a comprehensive consideration of material properties, process requirements and hygiene standards. The specific selection suggestions are as follows:
I. Material Selection
PU (Polyurethane) conveyor belt
Advantages: Oil-resistant, non-toxic, easy to clean, complies with food safety standards, and suitable for direct contact with food.
Applicable scenarios: Conveying of foods with high requirements for softness, such as bread and candies.
Teflon (PTFE) conveyor belt
Advantages: High temperature resistance (up to 300℃), strong non-stick and wear-resistant properties, and high dimensional stability.
Applicable scenarios: For the transportation of baked goods (such as cookies and puff pastry cookies), when rapid cooling is required.
Other materials
PVC: Suitable for common food, it is wear-resistant and corrosion-resistant but has poor heat resistance and is easily affected by oil stains.
Silicone: It can withstand high temperatures (up to over 200℃), but has poor flexibility and is prone to chip accumulation.
Ii. Key Performance Requirements
High-temperature resistance performance
The baking temperature of cookies is usually between 180 and 200℃. High-temperature resistant conveyor belts (such as Teflon or PU belts with anti-stick coatings) should be selected.
Anti-stickiness
The surface of the biscuits is moist and prone to adhesion. It is necessary to choose a conveyor belt with a rough surface texture or a non-stick coating (such as diamond checkered).
Easy to clean
Biscuits tend to accumulate debris after cooling. The conveyor belt should be easy to clean, disinfect and replace. A seamless design is recommended to reduce gaps.
Size and Strength
Customize the bandwidth and length based on the equipment parameters to ensure the carrying capacity and avoid cracking due to excessive stretching.
Iii. Other Precautions
Heat dissipation performance
High-temperature environments will accelerate the aging of materials. It is recommended to choose conveyor belts with good air permeability (such as those with ventilation holes).
Antibacterial property
When in long-term contact with food, choosing antibacterial synthetic materials can reduce the risk of bacterial growth.
Customized service
Customize the conveyor belt structure according to specific process requirements (such as roller printing forming, cooling conveying, etc.) to ensure compatibility with the equipment.
