Abstract:
An ice cream making machine, comprising:an evaporator system having a refrigerant input, and a refrigerant output, the evaporator system having an interior surface defining a cooling chamber, the cooling chamber having an ice cream input and an ice cream output, the evaporator system having an outside surface, the outside surface and the interior surface defining an evaporator chamber, the refrigerant input being below the refrigerant output, the refrigerant input and the refrigerant output being in fluid communication with the evaporator chamber, the evaporator chamber being configured to have an auxiliary evaporator portion, the auxiliary evaporator portion being an outward vertical protrusion on an upper portion of the outside surface, the auxiliary evaporator portion located above a primary evaporator with respect to gravity, the primary evaporator completely surrounding the interior surface;a compressor having a compressor input coupled to the refrigerant output and a compressor output; anda condenser having a condenser input coupled to the compressor output and a condenser output coupled to the refrigerant input, whereby a refrigerant travels from the condenser through the evaporator system and to the compressor, the refrigerant being a liquid in the primary evaporator, thereby providing superior cooling in the evaporator.
