Abstract:
An ice cream machine, comprising:a cylindrical evaporator having a refrigerant input, and a refrigerant output, the cylindrical evaporator having an interior surface defining a cooling chamber, the cooling chamber having an ice cream input and an ice cream output; an evaporator reservoir having a reservoir input and a reservoir output, the reservoir input being coupled to the refrigerant output; a compressor having a compressor input coupled to the reservoir output and a compressor output; and a condenser having a condenser input coupled to the compressor output and a condenser output coupled to the refrigerant input, whereby the refrigerant includes a liquid in the cylindrical evaporator, the refrigerant accumulating as a vapor in the evaporator reservoir, thereby providing superior cooling in the cylindrical evaporator.
