ABSTRACT:
In a vacuum cooling apparatus, a hollow receptacle is provided, for containing a plurality of containers for containing materials to be cooled, the containers being slidably fitted in the receptacle one after another. The receptacle has through-holes formed therein at intervals corresponding to the dimension of the container which is measured in the axial direction of the receptacle in such a manner that the receptacle through-holes are arranged in the axial direction of the receptacle. Each of the containers has a container through-hole formed therein so that the container through-hole is allowed to communicate with the receptacle through-holes. Seal members also are provided, allowing the inside of each container to communicate with the outside only through the receptacle through-hole and container through hole. A depressing unit inserts the containers into the receptacle from one end, and vacuum source units, coupled to a series of ones of the cylinder through-holes closest to the depressing unit, provide progressive stages of evacuation to cool food in the containers.
