Abstract: In an under the counter ice making machine for producing an ice product, a two-part freezer compartment is removably assembled to a frame. The freezer compartment includes an upwardly open box-shaped lower ice bin and an upper hood that is removably mounted in covering relation to the top of the ice bin. The ice bin is mounted to and removed from the frame only when the hood is removed. The ice bin has a rear end wall and a pair of sidewalls extending vertically upwardly and the bin is mounted by rotating the bin and its rear end wall into position on the frame and seated behind an abutment shoulder extending from the frame. Thereafter, the hood is assembled to and removed from the ice bin by a horizontal sliding movement of its sidewalls along the top surfaces of the bin sidewalls.

Abstract: An auger-type ice-making apparatus includes a new and improved auger or auger assembly having one or more generally spiral flight portions with one or more grooves formed transversely across the outer edges of the flight portions. The grooves interrupt the generally spirally-extending contact between the outer auger edges and the inner surface of an evaporator housing, thus reducing the area of contact therebetween and, as a result, reducing the load on the auger bearings. The grooves also provide a stress-relieved area on the flight portion during scraping of ice particles from the inner surface of the evaporator and tend to balance the forces on the auger bearings.

Abstract: An improved heat exchanger assembly is disclosed and has a wall composed of a heat transmissive material and a plurality of sections of spaced-apart elongated fluid conduits also composed of a heat transmissive material disposed on one side of the wall for conveying a heat transfer fluid therethrough. The assembly includes an elongated filler member, which either has a solid outer surface or is a wire mesh structure, and which extends longitudinally through the space between at least one adjacent pair of the spaced-apart elongated fluid conduits or conduit sections. The elongated filler member is also composed of a heat transmissive material and at least in part spaced from the fluid conduit or conduit sections, thus defining at least one opening providing communication into the space between the adjacent pair of fluid conduits.
