Abstract
An ice making device and a method of making ice. A plurality of passages for refrigerant, preferably, multi-component refrigerant, is in thermal communication with a freezing surface, for example in an outer shell surrounding a body. The passages each include an inlet and an outlet. The inlet for a passage may be disposed approximately 180° from the outlet for that passage. The outlet for the passages may form the inlet for the subsequent passage. The size of the outlets may be smaller than a cross-sectional size of the passage. As the refrigerant moves through the passages, water on the freezing surfaces will freeze and form ice. A blade will scrape the ice off.
