ABSTRACT:
A spiral type freezer constructed and operated to introduce refrigerated atmosphere into the bottom of the insulated chamber and circulate the atmosphere in a circulation flow from the bottom of the chamber to an exit on top of the chamber, the refrigerated atmosphere producing a thermal gradient from the bottom to the top of the chamber so that the freezer is operated non-isothermally.
