Abstract: Methods and apparatus for freezing a product. The product is frozen in a treatment container which contains a vibrating support. The vibrating support is capable of receiving a film of a cryogenic liquid. A heated temperature probe, located just before the outlet of the treatment container, measures the temperature at that location. The supply system for the cryogenic liquid has a proportional valve. A data acquisition and processing unit receives the temperature information and controls the opening of the proportional valve.

Abstract: The invention relates to a device for freezing articles, that comprises a conveyor with a porous belt maintained in position inside the device by drums, and a means for impregnating the belt of said conveyor with a cryogenic liquid, wherein the impregnation of the belt is carried out by partially or totally immersing the belt in a bath of cryogenic liquid, characterised in that it comprises a means for pressing the belt of the conveyor onto one of said drums.

Abstract: The invention concerns a method and an equipment for making ice cubes of liquid or pasty products comprising a honeycomb conveyor belt transporting the product to be processed along a path passing through at least the following three zones: a zone for metering and depositing the product to be processed in the cells; a cold input zone where preferably a cryogenic liquid solution completes the freezing of the ice cubes; and a stripping zone. Further, the honeycomb belt is bottomless, and located in an upstream zone opposite a cooled surface acting as a base of the partial mold formed by the cells, so as to harden the part of the product in contact with the cooled surface, thereby producing the base of the ice cube.
