ABSTRACT:
A method and apparatus for storing an ice slurry of a aqueous liquid is disclosed. A storage tank contains an ice slurry which is in the form of a layer of ice (i.e., an ice cap) floating on liquid. Liquid is pumped out from the lower part of the storage tank and fed to the top of the storage tank. The liquid which is fed to the top of the ice storage tank is returned to the lower part of the tank substantially without contacting the layer of ice contained therein via a vertically oriented tube. By pumping the liquid out of the lower part of the storage tank and recirculating it, pressure build-up due to the ice cap is controlled. In one embodiment, the liquid to be stored is a fruit juice such as orange juice, grapefruit juice, pineapple juice, grape juice, apple juice, or the like.
