PROCESS FOR FREEZING OR CHILLING ABSTRACT Chilling or freezing a substance into small pellets is disclosed. A substance such as liquid egg falls gently from only a small height onto the surface (12) of liquid nitrogen. The discharge nozzle (13) is prevented from freezing up by a flow of ambient or heated air over it. The surface of the boiling nitrogen is kept smooth by imparting a velocity to the nitrogen with an impeller (20) or by running the nitrogen along a trough. The pellets are consistent as to final temperature, and the process is efficient as to nitrogen use. The process can be used with other thick, creamy substances.
