An auger type ice making machine is provided with a control unit for causing a hot gas valve to open and for causing a heater disposed in the vicinity of ice compression passages to perform heating for a time period longer than the opening period of the hot gas valve, in accordance with a detection result from a rotation detecting sensor which detects rotation of a motor rotating an auger. The opening period of the hot gas valve and the heating period of the heater consist of, respectively: a basic opening period and a basic heating period, each corresponding to a time period during which the rpm of the auger is not higher than a threshold value, and an additional opening period and an additional heating period which are respectively added to the basic opening period and the basic heating period and begin at the time when the auger rpm exceeds the threshold value.
