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.

1. The method of producing salt-containing segments of ice in which the salt is substantially uniformly distributed throughout the ice segments comprising the steps of:pouring water containing salt into a horizontal mold divided into separate ice forming compartments; chilling said mold while in a horizontal position with a uniform application of coolant to an underside and sides of said mold at a sufficient rate of cooling to prevent desalination of the water in said mold and produce a single solid segment of salt-containing ice in and conforming in shape to each compartment; continuing said chilling until the temperature of the salt-containing ice in said mold is between minus 10° F. and minus 50° F. thereby producing supercooled segments of salt-containing ice in and conforming in shape to each of said compartments; and removing said segments conforming in shape to said compartments from said mold. 2. The method of claim 1 in which said segments of salt-containing ice are removed by rapidly subjecting said supercooled salt-containing ice segments to a short, temporary contact with a high heat source to melt a thin layer of salt-containing ice adjacent walls of said mold and rotating said mold to a substantially vertically oriented dump position whereby said segments of salt-containing ice are dumped from said mold into a collection bin.3. The method of claim 1 in which said water containing salt is seawater.4. The method of claim 1 in which said water contains salt in the amount of about 3% by weight of salt content.5. The method of claim 1 in which chilling is at the rate of about twenty to thirty minutes time duration.6. The method of claim 1 in which wherein said mold is tipped slightly during filling to discharge excess water into a trough, said mold being righted back into a horizontal position after said compartments are filled with salt water for freezing.7. The method of claim 1 in which said mold comprises an upper curved wall extending the length of said mold forming a first upwardly facing concave surface divided into and forming said compartments by a plurality of spaced separators and a lower curved wall having a second upwardly facing concave surface facing said upper curved wall forming an arcuate shaped passageway through the length of said mold, said upper and lower curved walls being joined at edges thereof.8. Supercooled segments of ice containing salt produced by the method of claim 1.9. Supercooled segments of ice containing salt made by the process of:pouring water containing salt into a horizontal mold divided into separate ice forming compartments; chilling said mold while in a horizontal position by the uniform application of coolant to an underside and sides of the mold at a sufficient rate of cooling to prevent desalination of the water in said mold and produce a single solid segment of salt-containing ice in each compartment, wherein each said single solid segment of salt containing ice conforms in shape to a compartment; and continuing said chilling until the temperature of the salt-containing ice in said mold is between minus 10° F. and minus 50° F. to produce supercooled segments of ice conforming in shape to said compartments. 10. The supercooled segments of ice of claim 9 in which the salt content of said segments is about 2.7% by weight.11. The supercooled segments of ice of claim 9 in which the salt content of said segments is in the range of about 2% to 4% by weight.12. The supercooled segments of ice of claim 9 in which said water is sea water.13. A method of producing beverage containing segments of ice in which non-water components are substantially uniformly distributed throughout the ice segments comprising the steps of:pouring water containing beverage components into a horizontal mold divided into separate ice forming compartments; chilling said mold while in a horizontal position by the uniform application of coolant to an underside and sides of the mold at a sufficient rate of cooling to prevent separation of the water in said mold and produce a single solid segment of frozen beverage in each compartment; and continuing said chilling until the temperature of the segment of frozen beverage in said mold is between minus 10° F. and minus 50 ° F. thereby producing supercooled segments of frozen beverage. 14. The method of claim 13 in which said segments of frozen beverage are removed by rapidly subjecting said supercooled segments of beverage to a short, temporary contact with a high heat source to melt a thin layer of frozen beverage adjacent walls of said mold and rotating said mold to a substantially vertically oriented dump position whereby said segments of frozen beverage are dumped from said mold into a collection bin.15.
