Abstract

The invention concerns a snowmaker including a hollow body (1) comprising a mixing and expansion chamber (2) defined by a peripheral wall (3) and communicating with outside through a ring-shaped coaxial outlet (4) around a central core (26). Water is introduced under pressure into the mixing and expansion chamber (2) through a plurality of helical ducts (6, 7) peripherally distributed about the longitudinal axis (I-I) to inject water along the peripheral wall (3) with a rotating motion. The pressurised air is introduced in the mixing and expansion chamber (2) in a central zone in one or several jets directed obliquely towards the peripheral wall (3) through a plurality of divergent air passages (11, 12). Such a snowmaker structure enables to produce quality snow from water and air at a lower pressure then in known snowmaker structures.
