An ice maker includes a casing that defines a chamber. The casing extends between a top portion and a bottom portion. An extruder die is mounted to the casing at the top portion of the casing. An auger is disposed within the chamber of the casing. A radial sleeve bearing engages the auger at the bottom portion of the casing. A radial and thrust bearing engages the auger at the extruder die. A related refrigerator appliance is also provided.

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.

The invention encompasses methods for the large-scale (preferably under cGMP or cGLP standards) preparation of micron-sized or submicron-sized particles including pharmaceutical or biologic active agents. The systems and methods include a cryogenic cooling system including a novel shroud that enhances the cooling effects thereby reducing product loss and increasing product yields.

A self-contained food processor is provided for treating a food flow path in the food processor with a solution. The food flow path can be treated without requiring disassembly and reassembly of the food processor and without requiring direct operator input. The food processor includes a controller for directing passage of a solution through at least portions of the food flow path without requiring constant operator oversight. The food processor can employ available positive pressure water supply, such as public utility water pressure to selectively and automatically push solutions, including rinses, backwards or forwards through the food flow path in the food processor.
