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 for artificial snow 10 formed at the other casing side wall 9 to blow out artificial snow, cut in a given amount, with compressed air. The impeller 4 is connected with the adjacent impeller at its end contacting impeller rotary shaft 3 by a smooth surface of arched plate 14 having arc 15. The opening for loading of artificial snow 7 on casing side wall 6 and the exit for artificial snow 10 on the other casing side wall 9 are arranged across from each other in arc 15 between impellers 4.
