Ice cream machine optimized to efficiently and evenly freeze ice cream

A frozen custard making system, comprising:

• a compressor having a compressor input and a compressor output;
• a condenser having a condenser input and a condenser output, the condenser input being coupled to the compressor output;
• and
• an accumulator/heat exchanger having a first input coupled to the condenser output, a first output coupled to an evaporator input, a second input coupled to an evaporator output, and a second output coupled to the compressor input;
• and
• an evaporator system having an evaporator input and an evaporator output, the evaporator system having an interior surface defining a cooling chamber for chilling a custard product, the evaporator system including an auxiliary evaporator for collecting vapor refrigerant, whereby the vapor refrigerant is substantially eliminated from the evaporator in an area by the cooling chamber.

An ice cream freezing machine, comprising:

• an evaporator having a refrigerant input and a refrigerant output, the evaporator having an interior surface defining an interior cooling chamber;
• the evaporator including an auxiliary evaporator, the auxiliary evaporator avoiding accumulation vapor in the evaporator in an area by the interior cooling chamber;
• a temperature sensor coupled to determine a temperature associated with the evaporator and to generate a temperature signal;
• a control circuit coupled to the temperature sensor, the control circuit providing indicia if the temperature signal is below a threshold;
• a compressor having a compressor input and a compressor output, the compressor input being coupled to the refrigerant output;
• a 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 to the compressor.
