Frequently Asked Questions
Q:
What is the temperature range of the Jiangsu Huada spiral conveyor belts?
The spiral conveyor belts are engineered to operate stably in extreme temperatures ranging from -40°C to 50°C, making them ideal for spiral freezers.
Q:
Are these spiral conveyor belts compliant with food safety regulations?
Yes, they are fully HACCP and FDA compliant. The design is non-toxic, PTFE-free, and certified under ISO 9001:2015, FDA 21 CFR 177.2600, and EHEDG EL Class.
Q:
How does the belt design reduce cleaning and maintenance time?
The sanitary design features quick-release tensioners and hinges that make the belt Clean-in-Place (CIP) ready. This reduces the cleaning cycle time to just 25 minutes, saving up to 50% of cleaning time compared to industry standards.
Q:
What materials are used in the construction of the spiral conveyor belts?
They are constructed using marine-grade 316L stainless steel with an electropolished finish (Ra ≤0.6μm) to ensure high corrosion resistance and hygienic food processing.
Q:
Can the airflow and belt width be customized for specific freezing systems?
Yes, the open area ratio is customizable from 45% to 85% for optimized airflow, and the belt width can be customized (e.g., 800mm width) to fit various tray systems and compact freezer designs.
Q:
How do these belts prevent food products from sticking during flash-freezing?
The belts utilize a micro-bump surface anti-stick design, ensuring zero product loss and smooth discharge even during high-volume Individual Quick Freezing (IQF) processes.
