SOLD | CES Cryogenic Spiral Freezer

Spiral freezing systems using liquid nitrogen (LN2) as a refrigerant. The CES spiral freezer consists of a freezer-belt encircling a rotating drum. The freezer-belt enters at the bottom of the drum at the infeed location and wraps in a helix to the top, where it makes a discharge. The belt returns through an automatic tensioner, take-up and anti-flip device. The heart of the structural system is the cage or the drum. The drum is driven and acts as a friction drive for the contacting inside edge of the belt and performs the vast majority of the work. The injection system and its controls will depend on the cryogenic refrigerant used, the size of the spiral freezer and the products to be cooled or frozen.
