Abstract
A method for manufacturing ice comprising the steps of: supplying gas into a pressure-resistant vessel containing ice grains, the pressure of the supplied gas being kept increased; applying a press force to the ice grains to increase the density of the ice grains, contact portions of the ice grains being allowed to be melted; and cooling the ice grains, in the pressed state, to freeze the ice grains. Gas to be introduced into the vessel is at least one selected from those of air, oxygen and carbon dioxide. An apparatus used for the method is also provided.
