Abstract
A post mix fruit juice dispenser having a refrigerated cabinet at the top which houses separate containers for different juice concentrates. The machine mixes potable water with the concentrate on demand. The potable water is cooled in an ice bath at the rear of the cabinet, and the same refrigeration system which cools the ice bath provides a source for cooling air circulated in the cabinet about the concentrate containers. The concentrate containers and their discharge assemblies may be removed from the machine for cleaning, but the containers may be replenished through filling assemblies at the top of the cabinet without removing them.
Claims18
A dual beverage dispenser comprising:
- a base and a cabinet mounted on the base, said cabinet being open toward the front,
- two containers in the cabinet for storing beverage concentrate to be mixed with water to make the two drinks to be dispensed by the dispenser,
- a hinged door for opening and closing the front of the cabinet,
- an ice bath at the rear of the cabinet,
- a stirrer having a propeller in the bath and a motor disposed above the bath,
- a refrigeration system including a compressor and condensor in the base and an evaporator in the bath for reducing the temperature of water in the bath,
- a pair of dispensing nozzles secured to the base and means connecting the respective nozzles to the different concentrate containers in the cabinet,
- a potable water circuit including an inlet for connecting a water source to the dispenser and a cooling coil in the bath for cooling the potable water, said circuit also including ducts connecting the coil to the inlet and to the dispensing nozzles,
- an air cooling coil forming part of the refrigeration system in series with the evaporator in the bath and disposed outside the bath in the cabinet,
- means including a fan in the cabinet for circulating air in the cabinet over the air cooling coil and about the concentrate containers in the cabinet to maintain the temperature of the concentrates in the cabinet at a selected level,
- and a mixing block in each nozzle for combining concentrate and potable water before they are discharged from the nozzles.
