  • Patent number: 3952538
    Abstract: A portable, convenient to use, self-contained apparatus for freezing liquids, such as ice cream, without the necessity of using ice and salt. The apparatus includes a housing with a heat conductive wall therein defining a cooling chamber of generally circular cross-section having an open upper end. A refrigeration device is contained in the housing and cooperates with the heat conductive wall over substantially the entire extent thereof for uniformly cooling the inner surface of the wall. A liquid container of generally circular cross-section corresponding to the shape of the cooling chamber is removably positioned within the cooling chamber in closely spaced relation with the uniformly cooled surface of the heat conductive wall and is adapted for rotation relative thereto. A drive mechanism provided in the housing is disengageably connected to the liquid container for rotating the container within the cooling chamber to thereby provide agitation for the liquid in the container during freezing thereof.
