Abstract: An ice making and crushing machine includes upright freezing plates for producing sheets of ice and and a pair of oppositely rotating ice breaking members below the plates for receiving the ice upon release by defrosting. The breaking members comprise sets of equally spaced disks each having equally spaced radial arms longitudinally aligned on the members. When rotating the disks form longitudinal pockets which receive and separate the ice in portions and crush it in successive batches. Substantially the entire area of the freezing plates is exposed to water on one side and refrigerant on the other for speeding the production of ice and the refrigerant circulating system affords equal cooling and the forming of ice of the same thickness on both plates.
