Abstract

A machine for making and harvesting blocks of ice which is totally automatic. The machine has an ice block forming ice chamber with a counter balanced hinged lid as the bottom wall of the chamber. A small amount of water is introduced into the lid which is frozen to form an ice seal between the bottom lid and the bottom flanged edge of the side walls of the chamber. The balance of the water according to the size of block ice is then introduced and frozen. The block is harvested by defrosting using a hot gas cycle to break the ice seal and defrost the side walls of the ice chamber. The ice block falls by gravity from the chamber onto a slide system. The hinged lid returns to the closed position and the machine restarts automatically to produce the next block of ice.
