  • Patent number: 4192151
    Abstract: An apparatus and a method for making ice are disclosed wherein ice forms on two sides of a plurality of freezing plates which are vertically arranged within a housing. A water distribution chamber positioned immediately above the freezing plates includes a plurality of inverted "V" shaped ridges in a bottom portion thereof. Each ridge corresponds to one of the plurality of freezing plates and includes a series of orifices arranged to direct water onto each side of the corresponding freezing plate. At the bottom of each freezing plate is a plastic strip which prevents ice slabs from the two sides of the plate from joining together at the bottom. Beneath the ice plates is a rotating sizer which fractures the ice slabs from the plates into pieces having a predetermined maximum size. The pieces fall through the sizer onto a screw conveyor which cooperates with a perforated lower housing to remove small undesirable ice pieces from the fractured ice.
