ABSTRACT:
An ice making machine includes a freezing plate having one surface placed in contact with an evaporator and the other surface serving as a freezing surface, and a water distributor for spraying water over the freezing surface. The water distributor comprises a pipe having a number of spaced orifices formed along the longitudinal direction of the pipe. Water is sprayed over the freezing surface. A dry zone or zone on which no water is sprayed is formed on the freezing surface at a location corresponding in position to the region of the one surface provided with the evaporator. Formation of ice starts from the boundary defining the dry zone, as the dry zone is inherently colder than the area on which water is sprayed, and a solid ice nucleus for propagating ice is formed therein, and proceeds to an ice slab over the whole freezing surface except the dry zone.
