Abstract
A flake ice machine (10) for producing flakes of frozen material. The machine includes a rotatable cooling disk (12) defining an external cooling surface (24) and an internal refrigerant flow passage (20). Refrigerant is supplied to the internal refrigerant flow passage to cool the disk. A motor drives rotation of the cooling disk, while a liquid material, such as fresh water, is supplied to the external cooling surface of the disk. An ice removal blade (30) is positioned adjacent the external cooling surface of the disk to remove flakes of frozen material. A low-wetting coating (90) is applied to the external cooling surface of the disk to enhance removal of large flakes of frozen material. In the preferred embodiment of the invention, the low-wetting coating comprises a fluoropolymer.
