Abstract
An apparatus for making artificial snow includes a flexible pipe which encloses a plurality of longitudinal conduits receiving and holding water therein. The pipe is cooled by a coolant liquid so that ice crystals form in the water on the surfaces of the conduits. A frame member is provided, oriented transversely to the axis of the pipe, which is movable axially along the pipe. Rollers provided on the frame member dislodge the ice crystals from the surfaces of the conduits. A seeve member is provided to strain the dislodged ice crystals from the water. The ice crystals are then conveyed to a desired area.
Claims16
Apparatus for making artificial snow, comprising at least one flexible conduit adapted to hold water;
- cooling means for cooling the conduit so that ice crystals form in the water on the surface of the conduit;
- means for temporarily deforming the conduit to dislodge the ice crystals so formed from the surface wherein the cooling means comprises a coolant liquid in thermal contact with the conduit;
- and
- a pipe containing a plurality of the conduits extending longitudinally therein, each of the conduits being a tube adapted to carry water, wherein in use the coolant liquid is passed through the pipe in thermal contact with the exterior surfaces of the tubes,
- wherein the pipe comprises a header portion at each end thereof communicating with respective end openings of each tube, one of said header portions communicating with an inlet pipe and the other header portion communicating with an outlet pipe.
Apparatus for making artificial snow, comprising at least one flexible conduit adapted to hold water;
- cooling means for cooling the conduit so that ice crystals form in the water on the surface of the conduit;
- a pipe containing a plurality of the conduits extending longitudinally therein, each of the conduits being a tube adapted to carry water, wherein in use the coolant liquid is passed through the pipe in thermal contact with the exterior surfaces of the tubes, each of said tubes being constructed of flexible material;
- and
- means for temporarily deforming the conduit to dislodge the ice crystals so formed from the surface;
- wherein the deforming means to dislodge the ice crystals comprises at least one frame member oriented generally transversely to the axis of the pipe and movable axially along at least a portion of the pipe, the frame member having thereon a first pair of parallel rollers located on either side of each of said tubes and spaced less than the diameter of the tube, a second pair of parallel rollers located on either side of each of said tubes and spaced less than the diameter of the tube, the first and second pairs of rollers being generally orthogonal to each other and to the tube, wherein the tube is deformed by the rollers as the frame travels along the pipe to thereby dislodge the ice crystals from the interior surface of the tube.
Apparatus, for making artificial snow, comprising at least one flexible conduit adapted to hold water;
- cooling means for cooling the conduit so that ice crystals form in the water on the surface of the conduit;
- means for temporarily deforming the conduit to dislodge the ice crystals so formed from the surface;
- and
- means for separating the ice crystals from the water, wherein the separating means comprises a sieve member for straining the dislodged ice crystals from the water, further comprising means for conveying the ice crystals to a desired area.
An artificial snow making system, comprising:
- a pipe member having a plurality of flexible tubes extending longitudinally therein, each of said tubes having one end connected to a source of water and its other end communicating with an outlet pipe;
- means for cooling a coolant liquid below 0.degree. C.;
- delivery means for circulating the coolant liquid through the pipe around the exterior of the tubes to thereby cool the tubes and promote the formation of ice crystals in the water on the inside surfaces of the tubes;
- means for dislodging the ice crystals from the inside surfaces of the tubes at predetermined intervals of time;
- and
- means for delivering the ice crystals to a desired location.
Snow making apparatus comprising
- at least one tube adapted to hold water;
- cooling means for cooling the tube below 0.degree. C. to thereby cause ice crystals to form in the water on the surface of the tube;
- means for draining the water from the tube;
- and
- means for blowing air through the tube to thereby dislodge the ice crystals so formed from the surface of the tube.
