Abstract
A frozen confection dispensing apparatus includes a refrigeration system. A variable frequency drive is connected to the refrigeration system. A beater motor is connected to the variable frequency drive. The variable frequency drive calculates the beater motor torque and regulates the refrigeration system activation. The variable frequency drive varies a speed and/or torque of the beater motor regulating a size of ice crystals and overrun of a frozen confection product.
Claims19
A frozen confection machine comprising:
- a refrigeration system;
- a controller communicatively coupled to the refrigeration system;
- a variable frequency drive communicatively coupled to the controller and to the refrigeration system;
- a beater motor connected to the variable frequency drive;
- wherein the variable frequency drive calculates a beater motor torque and transmits a data indictive of the calculation to the controller, and
- the controller is configured to:
- regulate the refrigeration system activation;
- and
- provide a command signal, based on the transmitted data, to the variable frequency drive to vary a speed of the beater motor regulating a size of ice crystals of a frozen confection product.
