ICE GENERATING DEVICE, IMPLEMENTING A DOUBLE-WALL CYLINDRICAL EXCHANGER, INCLUDING A BI-MATERIAL INTERNAL WALL

摘要

The invention relates to a device for generating ice, in particular ice in the form of scales, comprising: - a double wall exchanger (1) having an inner wall (13) and an outer wall (12) between which a refrigerant, the inner wall (13) having a cylindrical shape and being on the one hand in contact with the refrigerant and on the other hand to carry the ice forming; a mechanical assembly (2), (20), (21), (22), (23) mounted inside the exchanger, for unsticking the ice formed on the second surface of the inner wall, characterized in that the inner wall is made of two distinct materials of which a first material forms a first surface (130) suitable for food contact, intended to carry the ice in formation, and a second material which forms a second surface (131) in contact with the refrigerant.
