ABSTRACT:
In a system for producing clear ice bodies by dipping freezing fingers into a tank of water and causing the water to move about the fingers as ice builds up thereon in order to remove air and salt from the ice bodies, the amount of water required per unit weight of ice obtained (since the water remaining from each batch is ordinarily discharged on removal of the frozen fingers containing the ice bodies) is decreased by maintaining the fingers stationary and producing the water movement by moving the tank so as to produce tank-wall to tank-wall waves. The top portions of the freezing fingers are covered by the water only during the crest of the waves.
