Abstract: An apparatus preventing adhesion, growth and freezing of ice pieces, which tend to happen with quality artificial snow such as fine flake snow and powder snow. The rotary valve 1 to feed artificial snow at a constant rate includes: impeller rotary shaft 3 which is placed in cylindrical casing 2 along the length direction of the cylinder; a plurality of impellers 4 which are arranged around impeller rotary shaft 3 at an equal distance from each other in the radial direction; opening 25 for loading of artificial snow which connects the top portion of a wall of cylindrical casing 2 with the top portion of a housing; opening 7 for receiving compressed air which is formed on casing side wall 6 to receive said compressed air from a blower; and an exit 10 for artificial snow formed at the other casing side wall 9 to blow out artificial snow, cut in a given amount, with compressed air.

Abstract: Artificial snow making equipment includes an air-blowing pulverizer which prevents fluctuation in the size of ice pieces by eliminating fluctuation in the amount of ice blocks being supplied also eliminates blocking by the ice blocks, as a result utilizing air effectively such that the ice pieces are blown out as artificial snow the requisite distance. The artificial snow making equipment with constant forced blowing includes ice block supplier 1 to supply ice blocks at a constant rate and air-blowing pulverizer 11. The ice block supplier 1 has ice block supply opening 4 through which ice blocks 2 are supplied, casing 3 which has ice block supply opening 4; rotary blades 8 which supply ice blocks 2 at a constant rate while rotating in casing 3; and exit for ice blocks 5 which is positioned under casing 3.
