ABSTRACT:
An ice-making machine includes a plurality of heat exchangers disposed inside a housing and each having an inlet and an outlet to permit circulation of coolant therethrough. Each of the heat exchangers includes a pair of oppositely directed, corrugated heat exchange surfaces to transfer heat from the fluid within the housing to the coolant. Ice-making regions are disposed between the heat exchangers. These regions each have an inlet and an outlet to enable fluid to circulate therethrough. Blade assemblies are provided in each of the ice-making regions to co-operate with the heat exchangers to inhibit deposition of ice on the heat exchangers. These blade assemblies each include at least one blade of complementary shape to the corrugated heat exchange surfaces to contact respective ones of the surfaces. The blade assemblies are rotatable about an axis generally perpendicular to the plane containing the surfaces. Drive means rotate the blade assemblies at a rate such that the interval between successive passes of the blades in insufficient to permit crystallization of ice on the surfaces.
