  • Auger type ice-making machine
    Patent number: 6912868
    Abstract: An auger type ice-making machine of the present invention comprises an ice-making cylinder which accommodates an auger rotatably in the interior thereof, an ice compression head which supports the upper end portion of the auger rotatably, and which is disposed in the upper portion of the ice-making cylinder, and a cast-in heater which is attached to the outer peripheral surface of an accommodating portion for the ice compression head of the ice-making cylinder. According to the present invention, the use of a cast-in heater enables heat to be reliably transmitted to the ice compression head, whereby the compressed ice can be melted and ice can be discharged smoothly.
    Type: Grant

  • Auger type ice-making machine
    Patent number: 6691529
    Abstract: An auger type ice-making machine of the present invention comprises a tubular freezer casing which has an ice-making cylinder that rotatably accommodates an auger inside, an ice compression head which rotatably supports the upper end of the auger, a housing which rotatably supports the lower end of the auger, and a geared motor which is connected to the lower part of the housing. The geared motor drives the auger rotationally. And the auger type ice-making machine of the present invention further comprises a flange which constitutes an attachment base for the ice discharge tube attached to the upper part of the freezer casing. The flange is fastened to the ice-making cylinder by means of bolts that also fasten the ice compression head to the inside of the ice-making cylinder.
