ABSTRACT:
An automatic beverage dispenser having a multiflavor automatic beverage dispensing valve (faucet) and including means for preventing color and flavor carryover from one drink to the next. The automatic dispenser includes an electronic control system with an on-board computer with a microprocessor which, when a drink vend signal is received by the electronic control system, first checks to determine whether a dark or light colored drink was requested, then checks the last vend to determine if it was a light or dark drink. If the drink ordered was a light drink and the previous drink was a dark drink, then the controller looks to see if the cup dispenser position is occupied. If it is occupied, the flush is delayed until it is free when the soda water will flush to cleanse the nozzle. After flushing, the vend is processed.
