ABSTRACT:
In a process for freezing liquid or semiliquid food products in the form of essentially uniform pellets, the nonfrozen food product is introduced into a container. The product is agitated within the container, while a liquid cooling gas is sprayed over the product. The partially frozen food product is then removed from the container before it is completely frozen and after formability has been achieved, and is formed into essentially uniform pellets which are completely frozen outside the container. An apparatus for carrying the process into effect comprises a container, an agitator mounted within said container, spray nozzles opening into the upper part of the said container for spraying the underlying food product in the container with a liquid cooling gas, a forming device for forming the partially frozen food product removed from said container into essentially uniform pellets, and a freezer for completely freezing the pellets thus formed.
