ABSTRACT:
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.
