ABSTRACT:
A method of and an apparatus for the cooling of articles or materials in which the objects to be cooled are passed in succession through a precooling zone and a deep-cooling zone. A first cold-gas stream traverses the precooling zone in counterflow to the objects and is cooled by indirect heat exchange with a refrigerant while the objects in the deep cooling zone are cooled by direct heat exchange with a second gas stream produced by gasification of a liquefied gas. The second cooling-gas stream, after at least partial heat exchange with the objects or materials in the deep-cooling zone, is fed to the first gas stream prior to the cooling thereof by the indirect heat exchange.
