ABSTRACT:
A domestic ice-cream maker has a vertical cylindrical evaporator flanked by other parts of a refrigeration unit and a drive motor. A freezing support is removably located in the evaporator and a paddle in the freezing container is connected to the drive motor by a drive in a hinged lid covering the evaporator. The support is locked in place by freezing of moisture between it and the evaporator and released by a defroster associated with the evaporator which melts the moisture when ice-cream making is completed. The evaporation coil is situated in the space between inner and outer cylindrical vessels, the space being filled with a heat exchange liquid. The material being frozen may be aerated by providing air passages exiting at the trailing edges of the paddle adjacent the bottom of the container.
