An ice-making machine includes a housing having a brine solution inlet to receive brine solution from which ice is to be made and having an ice-brine slurry outlet to permit the egress of an ice-brine slurry from the housing. A heat exchanger within the housing has a heat exchange surface. The heat exchanger further includes a refrigerant inlet, a refrigerant outlet and at least one refrigerant circuit interconnecting the refrigerant inlet and the refrigerant outlet to permit a flow of refrigerant through the heat exchanger to extract heat from the brine solution contacting the heat exchange surface. The at least one refrigerant circuit is constituted by refrigerant passages integrally formed in a body portion of the housing. A blade assembly within the housing carries a plurality of blades each of which is in contact with the heat exchange surface. The blade assembly is mounted on a shaft which is rotatable by a motor to move the blades across the heat exchange surface to remove cooled fluid therefrom and inhibit the deposition of ice crystals on the heat exchange surface.

[ I claim:] [42.] An ice-making machine comprising:a housing including a tubular main body constituted by at least one solid body portion and defining a generally cylindrical, internal heat exchange surface, a fluid inlet to receive fluid from which ice is to be made to enable said fluid to contact said heat exchange surface and circulate through said housing, and an outlet to permit the egress of ice from said housing;blade means extending axially through said main body and contacting said heat exchange surface, said blade means being rotatable about a longitudinal axis of said housing to move across said heat exchange surface and remove cooled fluid therefrom;a drive rotating said blade means; andat least one refrigerant circuit including a refrigerant inlet, a refrigerant outlet, and a plurality of refrigerant passages interconnecting said refrigerant inlet and said refrigerant outlet, said refrigerant passages extending longitudinally through said at least one solid body portion at circumferentially spaced locations to permit a flow of refrigerant through successive refrigerant passages from said refrigerant inlet to said refrigerant outlet to extract heat from fluid contacting said heat exchange surface, each of said refrigerant passages having a different, generally constant cross-sectional area, each successive refrigerant passage having a greater cross-sectional area.
