ABSTRACT:
A beverage dispenser provides numerous inventive features in its refrigeration system (82), diluent delivery system (78), concentrate delivery system (74), mixing and dispensing system (76), and control system. The refrigeration system (82) employs a plate heat exchanger to provide on demand refrigeration of an intermittent water flow. The diluent delivery system includes a flowmeter/solenoid/check-valve assembly. The concentrate delivery system employs a positive displacement pump. The mixing and dispensing system includes a mixing nozzle (80) that has a locking feature such that an elevated blocking surface directly faces the inlet of pressurized diluent to create turbulence. The control system receives package-specific information from a scanner and diluent flow rate information from the flowmeter, and then determines the pump speed in order to set a desired mix ratio.
