How an Industrial Cooling Tunnel Works
Products enter the cooling chamber on a conveyor and move through a controlled stream of chilled air. The refrigeration system removes heat from the product while the conveyor determines residence time inside the tunnel. In the ZS-CT3, the reciprocating conveyor extends the travel path within a compact machine footprint.
Best-Suited Products
The ZS-CT3 is suitable for products that require controlled cooling or solidification after heating, filling, molding, coating or baking. Typical applications include chocolate, confectionery, bakery products, creams, balms, salves, ointments, wax-based products and other compatible heat-processed materials.
Why Use a Reciprocating Conveyor?
A reciprocating conveyor creates a longer product path by moving products back and forth inside the cooling chamber. This increases cooling residence time without requiring the tunnel itself to become proportionally longer, which can be useful where factory floor space is limited.
Cooling Tunnel vs Ambient Cooling
Ambient cooling relies on surrounding room conditions and typically offers less control over cooling time and temperature. A refrigerated cooling tunnel provides a dedicated controlled cooling environment and continuous conveyor flow, making it more suitable for production lines that require repeatable cooling before packaging.
