ABSTRACT:
An apparatus for production of compression-solidified snow comprises a pressure chamber with a rust preventive inner face, a pressure head for applying pressure to snow, a boost-typed pressure cylinder installed at one end of the pressure chamber and equipped with the pressure head, a hopper having an inner face which allows snow to slide thereon smoothly, and a pusher installed in a snow compression zone at the other end of the pressure chamber. A method of compressing snow into solidified snow lump is characterized in that snow having a temperature of 0.degree. to -30.degree. C. is compressed and formed with a pressure of 10 to 200 kg/cm.sup.2 at a head displacement velocity of 0.1 to 150 mm/sec for pressure holding time of 0-300 seconds into a solid having a density of 0.6 g/cm.sup.3 or more.
