A clean in place assembly for a soft serve ice cream dispenser includes an ice cream dispenser. A clean in place system having a water tank including a heater disposed therein is attached to the ice cream dispenser. A control interface is disposed on the tank. The control interface is connected to operating circuitry of the ice cream dispenser. A nozzle of the ice cream dispenser is formed of a conductive metal material and includes a notch formed therein circumferentially about a portion of the nozzle and includes radiused surfaces that extend to portions of the nozzle that house O-rings.

Automated clean in place system for soft serve machine

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.

Inverter motor drive for frozen confection machine and process for controlling a frozen confection machine

A frozen confection dispensing apparatus includes a freezer section having a base product. A dispensing section is connected to the freezer section. The dispensing section includes a mixing cylinder and a plunger movably positioned within the mixing cylinder, the mixing cylinder including at least one injection port. A flavoring section includes a plurality of flavor syrups connected to a specified injection port. A stepper motor is connected to the plunger and moves the plunger within the mixing cylinder. A control mechanism is connected with the stepper motor and syrup pump selectively moving the plunger wherein a syrup dispense rate and timing is sequenced by the control mechanism with the stepper motor driven plunger wherein mixing of the base product and flavor syrup is precisely controlled.

Integrated motor drive system for soft serve dispenser

An improved refrigeration compressor actuator is described for a chilled food dispensing apparatus. The actuator is connected to a temperature sensor located near or at the evaporator unit of the apparatus. The temperature of the apparatus is controlled by a compressor actuator that measures the temperature from the temperature sensor and is responsive to the rate of change in temperature per unit time.

Chilled food product dispenser and method with adaptive control of refrigeration system

A soft serve dispensing machine includes a refrigerator cabinet. A door is hinged to the refrigerator cabinet. A freezer compartment is defined in the refrigerator cabinet and receives a soft serve product mix. Product pumps are linked with the soft serve product mix for moving the product to a dispensing portion of the soft serve dispensing machine. The product pumps are positioned proximate the front portion of the refrigerator cabinet and above the freezer compartment. A removable inner door panel is moveable between stored and deployed positions. In the deployed position, the door is in an open position and the inner door panel is attached to the refrigerator cabinet and defines a seal relative to the refrigerator cabinet and cold air within the freezer compartment is maintained in the freezer compartment while the product pumps are accessed.

Inner door system for soft serve machine

A frozen confection dispensing apparatus includes a freezer section and a dispensing section connected to the freezer section. A mixing section is attached to the dispensing section. A user interface allows a user to select a desired flavor. A flavoring section includes a plurality of flavor syrups connected to at least one of injection port within the mixing section. A motor assembly turns a shaft and includes a mixing blade to regulate flow of frozen confection product within the mixing section as well as to blend or homogenize the frozen confection product and flavor syrup at the point of dispense.
