ABSTRACT:
An auger type ice making machine is provided with a freezing cylinder into which water for making ice is supplied, an ice-scraping auger for scraping ice formed on the inner surface of the freezing cylinder, and an auger motor for driving the ice-scraping auger. A freezing apparatus has a compressor driven by a motor, circulating refrigerant discharged from the compressor through a condenser, a dryer, a constant pressure expansion valve, and an evaporator provided on the outer peripheral surface of the freezing cylinder. At the outlet of the evaporator there is provided a temperature sensor for sensing refrigerant temperature. A controller controls the rotational speed of the motor through an inverter circuit such that the sensed refrigerant temperature is equal to a specified refrigerant temperature, allowing the freezing apparatus to keep ice-making performance thereof.
