ABSTRACT:
An auger-type ice making machine includes a refrigerating cylinder 5, an auger 6 disposed rotatably within the refrigerating cylinder 5 and provided with a spiral blade 6a, a driving motor 8 for driving rotatively the auger 6 and an electric heater mounted around an outlet end portion of the refrigerating cylinder into and through which ice is transported under the effect of rotation of the auger. A coolant vaporizing tube is wound around outer periphery of the refrigerating cylinder, and raw water is fed into the refrigerating cylinder via a feed water pipe. When jamming of ice takes place within the refrigerating cylinder 5, an overcurrent flows through the driving motor 8. The overcurrent is detected by a protector 23 incorporated in a control circuit 30, whereupon the electric heater 22 is electrically energized.
