DEVICE FOR GENERATING ICE, USING A DOUBLE-WALLED CYLINDRICAL EXCHANGER, OF WHICH AN INNER WALL IS A BI-MATERIAL WALL

摘要

The invention concerns a device for generating ice, in particular ice in the form of flakes, comprising: - a double-walled exchanger (1) having an inner wall (13) and an outer wall (12) between which a refrigerant flows, the inner wall (13) being cylindrical and being in contact with the refrigerant and being intended to carry the ice that is being formed; - and a mechanical assembly (2), (20), (21 ), (22), (23) mounted inside the exchanger, intended to detach the ice formed on the second surface of the inner wall, characterised in that the inner wall is made from two distinct materials, of which a first material forms a first surface (130) suitable for food contact, intended to carry the ice that is being formed, and a second material that forms a second surface (131) in contact with the refrigerant.
