  • Apparatus and method for preventing icing on a snow-making machine
    Patent number: 4083492
    Abstract: A snow-making machine which includes a tunnel-like housing, a fan to create an airstream, and nozzles for the formation of ice nuclei and water droplets. The fan is secured within the housing upstream of the nozzles. An inlet screen is secured to the housing upstream of the fan. The screen is heated to prevent the accumulation of ice on the screen. A shield is placed upstream of the fan to prevent the flow of air across the portion of the fan where ice would adhere to the fan.

  • 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.
