ABSTRACT:
In an auger type ice making machine having an upright evaporator housing the internal wall of which is formed with a cylindrical freezing surface, and an auger mounted for rotary movement within the evaporator housing to scrape ice crystals off the freezing surface and to advance the scraped ice crystals toward an upper end of the housing, an extruding head assembly mounted on the upper end of the evaporator housing includes a cylindrical head member coaxially coupled with the upper end of the evaporator housing, the head member having an internal cylindrical wall formed with a plurality of circumferentially equally spaced radial projections forming a plurality of circumferentially equally spaced compression chambers to which the scraped ice crystals are successively introduced under the action of the auger, and a thrust mechanism mounted on an upper end of the auger to compress radially outwardly the ice crystals introduced into the compression chambers in accordance with rotation of the auger.
