Stainless Steel Spiral Freezer Belt

A spiral freezer belt is the mechanical core of any spiral freezing or cooling system. It continuously transports products through a vertical helical path, from ground-level infeed to multiple stacked tiers, while high-velocity refrigerated air circulates freely through the open mesh at every level.

Designed for demanding food-processing environments, the belt must maintain reliable tracking and smooth link engagement at operating temperatures as low as −40°C. It also needs to handle continuous production loads without excessive sagging or misalignment, while withstanding daily CIP chemical cleaning cycles for long-term service.

EPFilter manufactures stainless steel spiral freezer belts in food-grade SS304 and SS316, available in three major drive configurations to suit different spiral conveyor designs. Whether you are building a new spiral freezing system or replacing an existing belt, we can provide customized solutions to match your equipment and production requirements.

Key Features

Low-Temperature Performance: Designed for reliable operation in freezing and cooling environments down to −40°C.

Stable Belt Tracking: Engineered for smooth running, consistent link engagement, and reliable conveying through multiple spiral tiers.

Heavy-Duty Construction: Stainless steel structure supports continuous production loads and demanding operating conditions.

Food-Grade Materials: Available in SS304 and SS316 stainless steel for food-processing applications.

CIP Cleaning Compatibility: Suitable for regular cleaning and sanitation requirements when the selected material and design match the cleaning chemicals and conditions.

Flexible Drive Options: Available in three major drive configurations for new installations and replacement projects.
