9. A method of sanitizing an ice cream dispenser comprising the steps of:

providing an ice cream dispenser including a nozzle wherein the nozzle of the ice cream dispenser is formed of a conductive metal material;

providing a clean in place system, the clean in place system including a water tank including a heater disposed therein and a control interface disposed on the tank, the control interface connected to operating circuitry of the ice cream dispenser;

performing a set up procedure;

performing a rinse cycle preparation cycle;

performing a rinse cycle;

performing a heat preparation cycle wherein water in the tank is circulated in the tank and the heater is activated heating the water in the tank to a temperature of from 160 to 185 degrees Fahrenheit;

performing a heat cycle wherein the heated water is cycled to the ice cream dispenser for a predetermined amount of time sanitizing the ice cream dispenser.

10. The method of claim 9 wherein the setup procedure includes the steps of:

coupling the clean in place system to the ice cream dispenser;

disconnecting mix lines from product bags of the ice cream dispenser;

attaching connections to an outlet of the tank;

attaching connections to bag adapters of the ice cream dispenser;

attaching connections to a spigot of the ice cream dispenser;

connecting a water source to an inlet of the tank; and

connecting a power source to the clean in place system.

11. The method of claim 9 wherein the set up procedure includes the step of loading sanitizer into a compartment of the tank.

12. The method of claim 9 wherein the rinse cycle preparation cycle includes the steps of:

opening spigots and air bleed lines of the ice cream dispenser;

feeding water to the tank through an inlet into the tank;

closing a valve at an outlet of the tank;

turning on pumps associated with the ice cream dispenser flowing water to bag connections of the ice cream dispenser.

13. The method of claim 9 wherein the rinse cycle includes the steps of:

flowing water from the tank through bag connections through pumps of the ice cream dispenser to cylinders and out through spigots;

directing connections at the spigots routing the water to a switch valve and to a drain;

enabling and disabling beaters of the ice cream dispenser.

14. The method of claim 9 wherein the heat preparation cycle includes the steps of:

closing a water valve at an inlet of the tank;

activating the heater;

16. The method of claim 9 further including a drain cycle including the steps of:

closing a water valve at an inlet of the tank;

deactivating the heater;

actuating a switch valve to a drain and the tank;

opening a drain valve to the tank;

running pumps until all of the water has been removed from the tank.

17. The method of claim 9 further including a final rinse cycle including the steps of:

opening a water valve at an inlet of the tank;

actuating a switch valve to a drain;

running pumps of the ice cream dispenser flowing water through the ice cream dispenser cooling the ice cream dispenser to room temperature.

18. The method of claim 9 wherein the rinse cycle further includes heating the water to a temperature of from 110 to 120 degrees Fahrenheit.
