Abstract
An ice making apparatus is disclosed which includes a refrigeration system and a new and improved combination evaporator and ice-forming assembly for making flake or chip ice. The combination assembly preferably includes a generally horizontal freezer plate with a freezer surface thereon, which is adapted for receiving make-up water thereon. An evaporator means in close physical proximity with the opposite side of the freezer surface functions to form a thin layer of hard-frozen surface ice on the freezer surface and a rotatable ice breaker disposed closely adjacent the freeze surface fractures the substantially fully frozen ice surface layer from the freezer surface into formed ice particles. Preferably, at least the freezer plate and the evaporator coil are integrally encased and molded into a monolithic freezer member composed of a molded polymeric material, with the freezer surface exposed for forming the ice layer thereon. The ice breaker is also preferably composed of a molded polymeric material. The assembly also includes means for compressing quantities of the formed ice particles in order to compressively remove unfrozen water therefrom.
