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.
Claims4
A machine for making ice cream and similar cold products comprising a removable ice cream making vessel, a support structure with a base housing, and a substantially cylindrical cooling chamber mounted on said base housing for receiving said removable ice cream making vessel, said cooling chamber having a side wall, at least said side wall of said cooling chamber having a circular cross-section which is incompletely closed on itself whereby it defines a slot extending along a generatrix, said side wall including an outer substantially cylindrical resiliently deformable layer, a stratum of elastically yielding material fixed inside said layer, ducts for circulating refrigerant fluid fixed within said stratum, and means for enlarging said cooling chamber by widening said slot against the resilient reaction of said outer layer, said cooling chamber being mounted on said base housing by means of a first vertical pin located in correspondence with said slot and a second vertical pin in a position diametrically opposite said first pin.
