Abstract (en)
A system for producing block ice treated with nitrogen substitution includes a nitrogen gas supplying unit for supplying nitrogen gas under a predetermined pressure; a cooled nitrogen-dissolved water producing unit for producing nitrogen-dissolved water, which is provided with a water receiving tank for storing material water, a cooler for cooling the water stored in the water receiving tank, and a nitrogen gas injector for injecting nitrogen gas supplied from the nitrogen gas supplying unit into the water stored in the water receiving tank; and a nitrogen-substitution block ice producing unit which is provided with a plurality of ice cans immersed in a brine tank kept at a freezable temperature for water, a filling device for filling each of the ice cans with the nitrogen-dissolved water supplied from the nitrogen-dissolved water producing unit, and a gas injector for injecting nitrogen gas supplied from the nitrogen gas supplying unit into an unfrozen portion of the nitrogen-dissolved water.
