ABSTRACT:
The present invention includes a counter top unit for dispensing the partially frozen beverage and, at one or more locations remote from that unit, two syrup supply canisters, a source of CO.sub.2, and a condenser and compressor unit that provides refrigeration coolant to the counter top unit. Supply and return lines carry the refrigeration coolant between the counter top unit and the compressor/condenser unit. The counter top unit includes a compact housing that is adapted to be set on the counter top. Inside the counter top unit is a pair of cooling chambers. Each cooling chamber produces, holds and dispenses a partially frozen beverages. The cooling chamber includes agitators, that mix the partially frozen beverage, and cooling coils, that are coupled to the refrigerant supply and return lines, which cool the interior of the cooling chamber. Two pumps in the counter top unit mix the water and the syrups and the resulting mixtures are fed, along with a predetermined amount of CO.sub.2, into respective ones of the cooling chambers. Preferably, water is first fed into a reservoir tank in the counter top unit and then is drawn from the tank by the pump/mixer. The counter top unit also includes a motor that continually rotates the agitators in each of the cooling chambers via respective torque transmission units. Refrigeration controls and product controls regulate the flow of refrigeration coolant, CO.sub.2, water and syrup into the cooling chambers.
