ABSTRACT:
A cabinet freezer efficiently utilizes a liquid cryogen refrigerant in conjunction with a spiral conveyor which conveys a product load through a temperature gradient within the freezer. The freezer has a lower inlet and an upper outlet for the conveyor and food load thereon. The escape of cryogen vapors created in the freezer from the liquid cryogen is controlled such that at least about 80% of the vapors exit through the upper outlet which is at the warmest zone established as a part of the temperature gradient in the freezer.
