Home » Freezer » Spiral
Spiral freezers are essentially a circular spiral freezer that convey the product from the top to the bottom or visa versa to allow the materials to be exposed to a freezer environment for a set period of time with all product seeing the same residence time for freezing. The spiral is contained in a refrigerated box or cage and the inlet and discharge are the only means for the product to enter or leave this continuous endless spiral. The cooling method for spiral freezers can be direct expansion refrigeration such as Freon or ammonia through evaporator coils or direct impingent using cryogenic gases Co2 or Nitrogen.
