<p>The invention is a snow gun (1) for the production of artificial snow (N), comprising an inlet mouth (3) and an outlet mouth (4) for the artificial snow (N). The gun furthermore comprises: an evaporation chamber (5), in such a way as to implement a process of evaporation of a portion of a liquid substance (S) in its triple point and substantially in vacuum conditions, obtaining steam (V); a condensation chamber (9) communicating with the evaporation chamber (5) through the interposition of compression means (8) suited to draw the steam (V) from the evaporation chamber (5), the condensation chamber (9) causing the condensation of the steam (V) that is compressed by the compression means (8); a crystallization tank (11) connected to the evaporation chamber (5) so as to transfer the remaining non-evaporated mixture (M) of the liquid substance (S) in the crystallization tank (11), in such a way as to implement a process of growth of the portion in the crystallization phase (C) in order to obtain the artificial snow (N); and finally a collection unit (17) suited to collect the artificial snow (N) and distribute it in the external environment.</p> |
