  • Apparatus and method for making snow with uniform drop size
    Patent number: 3948442
    Abstract: An airless snow-making machine is provided in which ice nuclei and water drops are formed separately, commingled, and discharged to form snow-like crystals. The water drops are uniform and are formed by cyclically disturbing linear water streams discharged from an orifice plate of a nozzle assembly. The cyclic disturbance effects the breaking off of water drops of uniform size from the fluid streams.
