Abstract:
1. A method of manufacturing ice cream machine, comprising: providing a liquid ice cream to a cooling chamber in a cylindrical evaporator having a refrigerant input, and a refrigerant output, the cylindrical evaporator having an interior surface defining the cooling chamber, the cooling chamber having an ice cream input and an ice cream output; and providing refrigerant to the refrigerant input, the refrigerant traveling to an evaporator reservoir having a reservoir input and a reservoir output, the reservoir input being coupled to the refrigerant output, the refrigerant accumulating as a vapor in the evaporator reservoir, the refrigerant flooding the evaporator in a liquid form due to the evaporator reservoir thereby providing superior cooling in the cylindrical evaporator; and removing frozen ice cream from the ice cream output.
