a high throughput , short batch cycle commercial ice making machine produces commercial ice which resists melting in convenient sizes for mobile food carts , market produce , or fish displays . the machine introduces super - cooled water , that is in a liquid state while exposed to a temperature below freezing , into a batch of pre - formed hollow molds of one or more horizontally oriented ice forming freezing trays oriented horizontally . using vapor compression refrigeration , the machine produces a plurality of supercooled ice segments in pockets within the freezing tray . the supercooled ice segments are rapidly subjected to a short , temporary contact with a high heat source from a sleeve integral with the freezing tray compartments , along a peripheral bottom surface of the ice segment accommodating freezing tray molds . this temporarily melts a bottom surface of each ice segment , lubricating it and loosening it . then the machine rotates the freezing tray containing the batch of ice segments about its horizontally oriented axis to a vertically oriented dump position , thereby dumping the temporarily heated ice segments into the freezing tray . the ice cubes thus formed may be fresh water , salt water or beverage containing ice cubes .
