POSTMIX BEVERAGE DISPENSING SYSTEM

摘要

A postmix beverage dispensing system (10) for dispensing a finished beverage directly from a pliable beverage concentrate at freezer temperatures, without the need for forcing the concentrate through a heat exchanger. The system preferably uses a single blow molded disposable concentrate package having the two parts of a concentrate container (14), and a metering pump and mixing nozzle (30). The concentrate container is placed in a canister (26) and pressurized and a pump actuator (32) is connected to the metering pump along with a pressurized water line. The dispenser requires no cleanup or sanitization, because both of concentrate container (14) and pump and nozzle unit (30) are disposed of after depletion, and allows rapid flavor change. The invention includes an improved metering pump.
