Method for controlling and optimizing the cycle for production of ice cream depending on the mixtures used

An apparatus for controlling and optimizing the cycle for production of ice cream based on an ice cream mixture used in the apparatus, said apparatus comprising:

• a freezing cylinder exchanging heat with an evaporator of a refrigerating circuit, said evaporator having an inlet, an outlet, and refrigerating gas;
• an electric motor;
• a stirrer/scraper element rotatable inside said freezing cylinder and actuated by the electric motor;
• a processing element adapted for executing a software program;
• sensors for detecting, continuously, temperature values of the refrigerating gas at the inlet and at the outlet of said evaporator;
• and
• means for detecting, continuously, power values of the electric power used by said electric motor;
• wherein said temperature values and said power values are continuously input into said processing element;
• and
• said software program processing said temperature values and said power values so as to provide an output signal to drive an impulse solenoid valve for introducing continuously hot gases taken from an exhaust of a compressor into a main stream of refrigerating fluid.
