Abstract
A drink dispensing system having sets of faucet dispensers, ice storage bins adjacent to the sets of faucet dispensers, respectively, a common carbonator and circulation pumps associated with fluid circuits provide circulating flow through cold plates defining bottoms to the ice storage bins. Flow may be in parallel or in series to each of the separate stations. The circulating system is illustrated to be for the carbonated water supply while noncirculating supply systems provide noncarbonated water and syrup to the dispensing stations. Circulating systems for bar guns using a cold plate is also disclosed.
Claims32
A drink dispensing system comprising
- at least one dispenser valve;
- a carbonator;
- an ice storage bin including first heat transfer coils therein;
- a carbonated water circulation circuit, the carbonator and the first heat transfer coils being in the carbonated water circuit, the dispenser valve being in fluid communication with the carbonated water circuit;
- a pump capable of being coupled for fluid communication in the carbonated water circulation circuit, the carbonated water circulation circuit being a closed loop in operation including fluid communication fully about the closed loop in at least one direction among the carbonator, the dispenser valve and the first heat transfer coils independently of the pump.
