ICE SLURRY MACHINE

An apparatus and method for producing an ice slurry for use as a refrigerant employs a freeze chamber (34) for receiving a refrigerant solution such that, in use, liquid freezes out of the refrigerant solution to form frozen particles on a curved internal circumferential wall of the freeze chamber (...

Beschreibung
Zusammenfassung:	An apparatus and method for producing an ice slurry for use as a refrigerant employs a freeze chamber (34) for receiving a refrigerant solution such that, in use, liquid freezes out of the refrigerant solution to form frozen particles on a curved internal circumferential wall of the freeze chamber (34). The frozen particles are sheared from the wall by a vortex induced in the solution with an auger (45) such that the particles are entrained in the solution creating an ice slurry. A cage (56) is free to rotate in the freeze chamber (34) and assist shearing of the frozen particles from the wall. The relative speed of rotation between the auger (45) and cage (56) can be used to control cooling means for forming the frozen particles on the wall such that an ice fraction is produced that is suitable for suitable for use as a refrigerant. The ice slurry refrigerant may be used to cool a beverage product transferred from a bulk storage location to a dispense point, for example to cool beer contained in a beer line between a keg and a dispense tap.
