ABSTRACT:
Machine adapted to be incorporated in a refrigeration chamber of a refrigerator to make ice cream, comprising means for containing an ice cream mix in an agitation vessel and agitating the same, and means for causing an air layer on the outer surface of the agitation vessel to move. The provision of the air layer moving means is effective to promote heat exchange between the outer surface of the agitation vessel and the cold air in the refrigeration chamber by forcedly moving the air layer which might otherwise interfere with the exchange of heat between the outer surface of the agitation vessel and the cold air in the refrigeration chamber.
