Beverage dispenser

A dispenser system, comprising:

• a beverage syrup source;
• a carbonator coupled to a source of carbon dioxide gas and to a water source to produce carbonated water;
• a cooling unit that cools beverage syrup delivered from the beverage syrup source;
• an agitator disposed in the cooling unit wherein the agitator circulates cooling fluid contained within the cooling unit;
• a dispensing station coupled with the beverage syrup source and the carbonator, whereby the dispensing station combines the beverage syrup and the carbonated water to produce a dispensed product;
• a sensor that measures an operating parameter of the dispenser system and outputs a signal representative thereof;
• and
• a controller that monitors the signal output by the sensor, whereby the controller operates the agitator at a lower speed when the signal output by the sensor indicates the dispenser system is operating in a desired stable state, and further whereby the controller operates the agitator at a higher speed when the signal output by the sensor indicates the dispenser system is not operating in the desired stable state.

A method of controlling a dispenser system, comprising:

• providing an agitator operated to circulate cooling fluid contained in a cooling unit of the dispenser system;
• measuring an operating parameter of the dispenser system;
• outputting a signal representative thereof;
• operating the agitator at a lower speed when the signal output by the sensor indicates the dispenser system is operating in a desired stable state;
• and
• operating the agitator at a higher speed when the signal output by the sensor indicates the dispenser system is not operating in the desired stable state.
