ABSTRACT:
The disclosure relates to a method for making artificial snow involving the induction of compressed air into an annular disposed chamber and through a multitude of circumferentially and longitudinally spaced, radially inward directed orifices to be mixed with a steady stream of water. The mixture is then forced through a multitude of longitudinal directed orifices, where a substantial pressure drop subsequent to egress from the orifices causes a first stage atomization of the water into tiny, uniformly sized droplets and the concurrent pre-cooling of the droplets. The droplets are ten accelerated through an exit nozzle, where the final expansion of still partially compressed air to atmospheric pressure causes the final atomization, and the projecting of a thereby produced plume of water droplets through an trajectory within the cooler atmosphere along which the droplets are allowed to freeze into tiny, crystalline particles of ice before falling to the ground.
