Abstract

The invention deals with the problem of production of artificial snow (7) by means of snow guns (1,2, 2') when the streams of water (5, 5') or drops of water in a stream of water or water fog (6) leaving the output of the snow gun (1, 2, 2') crystallize after landing on the landing area (3) where they either crystallize in a large piece of ice resulting in creation of dangerous icy plates in the neighborhood of snow guns (1, 2, 2') or they fail to crystallize and flow away. The subject matter of the invention consists in creation of at least one impact area (4) in the distance of at least 2 m from the output of a snow gun (1, 2, 2') between the output of at least one snow gun (1, 2, 2') and the landing area (3). The individual streams of water (5, 5') and/or drops of water carried in a stream of air and or droplets of water fog (6) are directed in the impact area (4) so that they hit each other and/or a fixed obstacle to reduce their internal energy and on the route between the impact area (4) and landing area (3) they subsequently crystallize in their whole volume and form artificial snow (7) falling on the landing area (3) in a fully crystallized state. Artificial snow (7) produced according to this method does not form icy plates, is easy to manipulate with and can be stored in piles when it is maintained in a loose state.The apparatus for production of artificial snow (7) can be formed by a tubular snow gun (1) with a fan (8) and nozzles (9) provided with a routing extension (10) or with a routing mouth (11) to direct the output in the impact area (4). The apparatus for production of artificial snow (7) can also be formed by a tubular snow gun (1) or a shower snow gun (2, 2') provided with a hydrophobic sieve (12). The impact area (4) can also be created by directing the streams of water (5, 5') from two shower snow guns (2, 2') against each other.
