Method and apparatus for producing snow using ultrasonic waves

A method for artificially producing snow, which is used for an indoor skiing facility. The method comprises maintaining an inside temperature of the indoor skiing facility of 0.degree. C. or less and blowing air and water with an air-water ratio of 300 to 3000 Nm.sup.3 /m.sup.3 in volume from a plurality of two-fluid spraying nozzles to generate and spread waterdrops of a particle size of 5 to 200 .mu.m, into the indoor skiing facility. The spray nozzles are disposed adjacent an upper portion of a cover enclosure of the indoor skiing facility. An apparatus for artificially producing snow. The apparatus comprising an indoor skiing facility having a floor and a cover enclosure comprising a ceiling and side walls. The cover enclosure and the floor are made from an insulating material. Holes are provided for blowing cold air into the indoor skiing facilities. The holes for blowing air are disposed adjacent an upper portion of the cover enclosure. Holes are provided for exhausting air from the indoor skiing facilities. The holes for exhausting air are disposed adjacent a comparatively lower portion of the side walls of the cover enclosure. A plurality of two-fluid spray nozzles are provided for blowing air and water into the indoor skiing facilities. The spray nozzles are disposed adjacent the upper portion of the cover enclosure.

Method for producing snow and apparatus therefor

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.
