The freezing process
The products to be frozen are placed on a conveyor belt which spirals through the freezer. The cryogen is sprayed horizontally out of vertical headers mounted in the corners of the box.
Since the cold gas flow is not injected directly onto the product, spiral freezers are typically not as effective as straight freezing tunnels. However, they still provide relatively rapid freezing, high process efficiency and continuous production.
Performance
- production rates range from 400 kg/hr to 4500 kg/hr
- the lowest operating temperature is usually -73°C
