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 (). An 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. As a result, the auger type ice making machine can keep ice-making performance regardless of changes in ambient temperature or water temperature, securing stable ice generation and consistent quality of ice.
