An apparatus for freezing and dispensing semi-frozen food products having two freezing chambers, one compressor for supplying refrigerant to both freezing chambers, one beater drive motor for driving the beaters in both chambers, two solenoid valves control flow of refrigerant from the single compressor to the evaporators for the freezing chambers and periodic pulse width modulated signals are applied to operate the two solenoid valves alternately during each period and signals are modulated to have substantially equal duty cycles in an initial freeze mode and to have unequal duty cycles when product is dispensed from only one freeze chamber.
