ABSTRACT:
An ice cream-making machine with an ice cream-making vessel which can be inserted in and removed from a substantially cylindrical cooling chamber with a circular cross-section that is not completely closed on itself due to the presence of a slot extending along a generatrix of the cylinder. The side wall of the chamber includes an outer layer, a stratum of elastically-yielding material, ducts for circulating a refrigerant fluid, and means for enlarging the chamber by opening the slot against resilient means to allow the insertion or removal of the ice cream-making vessel. Thus, effective contact between the ducts for circulating the refrigerant fluid and the ice cream-making vessel is always ensured and the performance of the machine is optimized.
