ABSTRACT:
An ice making machine comprises a vertically aligned, cylindrical cooling cylinder of hollow annular section, a motor driven auger disposed within the inner periphery of the cooling cylinder, and an external cooling system including a compressor and heat exchanger as in the conventional fashion. Water is pumped into a freezing cavity containing the auger that is defined between the inner periphery of the cooling cylinder and a concentric inner cylinder. The auger scrapes ice from the inner periphery of the cooling cylinder and forces the flakes upwards toward an ejector above the cooling cylinder. The improvement thereof comprises the inclusion of a second cooling cylinder wherein the first auger scrapes ice from the corresponding peripheries of both cylinders and the second auger scrapes in from the additional ice forming surface defined by the inner periphery of the second cylinder.
