Structure Analysis
- Stainless Steel Chain Base Stainless steel roller chain construction resists moisture, condensed water and rust inside cold tunnels. Single or double strand designs are available.
- Low-temperature Modified Nylon Rollers (Core Component) Made of cold-resistant PA material with self-lubricating property. The rollers remain flexible at sub-zero temperatures without cracking. Rolling contact with guide rails reduces driving resistance.
- Extended Outer Pins Extended solid pins protruding from outer plates are used to hang baking trays and material supports. Suspended conveying enables cold air circulation around products.
Key Features & Advantages
Excellent Low Temperature Resistance Nylon rollers stay tough under deep freezing conditions. Stainless steel components withstand condensate and ice water corrosion in cold storage.
Low Running Resistance Rolling friction saves power consumption and creates lower noise compared with sliding conveyor chains.
Optimized Air Circulation for Fast Freezing Suspended layout allows cold air to fully pass through goods, improving freezing uniformity and efficiency.
Protect Guide Rails Moderate-hardness nylon rollers prevent scratches on stainless steel tracks and extend service life of equipment.
Food Contact Safe Easy to clean and sanitize, compliant with food processing requirements.
Limitations
Nylon rollers are prone to aging above 60℃; only suitable for cold conveying, not high-temperature drying lines.
Avoid heavy impact and sharp objects to prevent roller damage.
Regular inspection of pin wear is recommended under long-term heavy load.
Typical Applications
IQF dumpling & meat freezing tunnels, fruit & vegetable cryogenic lines, aquatic product freezing equipment, bakery cooling conveyors, spiral freezer supporting chains, tray suspension freezing systems.
