A freezer having a freezing compartment and a porous conveyor belt far conveyingarticles through the freezing compartment. A vaporizer is provided to vaporize a stream of liquid cryogen. Vaporized cryogen is directed against the belt as a plurality of jets to blow accumulated ice off the belt. The vaporizer is located within the freezing compartment so that the cooling potential of the cryogen is not wasted and the vaporizer can serve as a preferential condensation site for the moisture.
Cette invention concerne un congélateur en continu composé d'un compartiment de congélation et d'une courroie transporteuse poreuse faisant défiler des articles dans le compartiment ci-dessus. Un vaporisateur de liquide cryogène dirige une série de jets de cryogène vaporisé contre la courroie pour la débarrasser de la glace accumulée. Le vaporisateur est placé à l'intérieur du compartiment de congélation afin d'exploiter le pouvoir réfrigérant du cryogène et de constituer un site préféré de condensation de l'humidité.
