Frequently Asked Questions (FAQ)
What is the operating temperature range of Huada spiral conveyor belts?
Our stainless steel spiral conveyor belts are engineered for ultra-low temperature efficiency, operating reliably within a temperature range of -40°C to 50°C. They have been tested for over 5000 thermal cycles.
Are these spiral freezer belts certified for food safety?
Yes, our belts are fully compliant with stringent food safety standards, holding ISO 9001:2015, FDA 21 CFR 177.2600, and EHEDG EL Class certifications.
What materials are used to manufacture the belts?
The belts are constructed from premium 316L stainless steel with an electropolished finish (Ra ≤0.6μm) and feature a non-toxic PTFE-free coating to ensure optimal hygiene and corrosion resistance.
How much faster is the freezing process compared to traditional belts?
Thanks to their customizable open area ratio (45-85%) and optimized airflow design, Huada spiral belts deliver up to 30% faster freezing compared to traditional belts.
Are these belts suitable for Seafood IQF processing?
Absolutely. For Seafood IQF (like shrimp and scallops), we provide a tailored solution featuring a 60% open area combined with marine-grade stainless steel to resist corrosion and prevent sticking.
How long does the cleaning and maintenance cycle take?
The cleaning cycle time is significantly reduced to just 25 minutes (CIP ready). The inclusion of quick-release tensioners helps reduce overall cleaning time by 50% compared to industry standards.
