Abstract:
A beverage dispensing system, comprising:a housing; a container defining a cooling chamber; a bath of cooling fluid disposed within the cooling chamber; a cooling unit including an evaporator coil extending from the cooling unit into the cooling chamber, whereby the evaporator coil is submerged within the bath of cooling fluid to freeze the cooling fluid thereabout, thereby producing a frozen cooling bank; sensor units whereby each sensor unit is positioned within the cooling chamber at a different location about and at a desired distance from the evaporator coil to provide output corresponding to the size and shape of the frozen bank; and a control unit operatively linked with the sensor units and the cooling unit, whereby, responsive to the output of the sensor units, the control unit controls the operation of the cooling unit to regulate the growth of the frozen cooling bank.
