ABSTRACT:
In order to freeze articles in containers, the side of the containers against which the material to be frozen would normally contact is provided with a frozen coating consisting of a lining material having a lower melting temperature than the material to be frozen. The article, after being frozen in the container, may be easily removed from the container by heating the container to a temperature between the melting point of the lining material forming the coating and the material of the article such that the article will be loosened with respect to the container without any melting (or distortion) thereof. An apparatus for carrying out the method comprises a first cooling coil for cooling the containers, a nozzle for providing the internal surfaces of the containers with a frozen coating consisting of a material which is easier to melt than the material to be frozen, a filling tube for introducing the material to be frozen into the cooled containers, and a second cooling coil for freezing the content of the containers.
