A method and apparatus for maintaining a liquid-frozen solid slush mixture in a vessel at a desired total slush mixture and desired solids content during conditions under which the solids in the slush mixture in the vessel are melting. The method comprises introducing fresh slush mixture to the vessel, while removing liquid from the vessel－both at rates directly proportional to the rate of solids melting in the vessel. The apparatus comprises an auxiliary vessel containing slush mixture and means for transferring slush mixture to the main vessel at one rate, means for transferring liquid from the main vessel to the auxiliary vessel at another rate, and means for controlling the transfer rates in a prescribed manner.

A method for maintaining the solids content and total quantity of a slush mixture in a primary vessel at predetermined values during a period of time when the solids of the slush mixture in the primary vessel are melting, which method comprises filling the primary vessel with the slush mixture substantially to a predetermined volumetric capacity of the primary vessel, providing a separate auxiliary vessel containing a quantity of slush mixture, transferring slush mixture from the auxiliary vessel to the primary vessel at a rate that will infuse solid particles into the primary vessel at a rate that is comparable to the rate at which the solid melts in the primary vessel, and transferring liquid from the primary vessel to the auxiliary vessel at a rate directly proportional to the rate at which the solid melts in the primary vessel; whereby the weight of slush mixture in the primary vessel is maintained at the predetermined value and the volume of the slush mixture in the primary vessel is maintained at the predetermined volumetric value.
