ABSTRACT:
An improved flake ice making machine is disclosed wherein flake ice is broken away from a submerged refrigerated surface by a rotating auger. A tank surface opposite the refrigerated surface has screw thread guides affixed to it which cooperate with the rotating auger to lift ice flakes over the tank wall and into an ice receiving channel encircling the tank wall. A sweeper arm rotates with the auger and sweeps the ice in the channel towards a discharge opening. Pressure sensitive switch means are connected for stopping rotation of the auger in response to an excessive accumulation of ice in the event of blockage of the discharge opening. The auger is supported only to a drive shaft extending through the evaporator so that there are no submerged bearings or bearing surfaces.
