The spiral quick-freezer is a piece of rapid-freezing equipment characterized by a compact structure, a wide range of applications, a small footprint, and high freezing capacity.

The spiral quick-freezer works on the principles of conduction, convection, and heat transfer. It rapidly freezes food by exposing it to a stream of extremely cold gas—usually liquid nitrogen or liquid carbon dioxide—which quickly draws heat away from the product.
Food enters through the infeed and moves along a spiral conveyor system. A rotating drum drives the mesh belt upward or downward in a spiral motion. This keeps food in full, continuous contact with high-speed freezing air during transport. Freezing air extracts surface heat, causing a rapid temperature drop. Convective heat transfer ensures even cooling throughout the product. Once fully frozen, food exits through the discharge opening.
The entire process runs on a single continuous belt. The spiral conveyor belt maximizes contact with the cold source. Constant tumbling during spiral movement accelerates freezing. This enables deep freezing to be achieved in a relatively short time.
