Artificial snow production apparatus |
摘要 |
An artificial snow generating apparatus having a vertical inner cylinder for generating and growing snow and an outer tank surrounding the inner cylinder and having a cooler for cooling the inner cylinder for an ice crystal quantitative feeder for generating and feeding a predetermined quantity of ice to a lower part of the inner cylinder from a cooled spray chamber into which a spray producing nozzle sprays water from a feed water tank by aspiration with air from a saturation tank containing water. A blower periodically blows humidified air through the spray chamber to blow ice particles into the inner cylinder. The apparatus also has a cloud-forming water quantitative feeder for generating and feeding a predetermined quantity of particles of cloud-forming water having a predetermined particle size to the inner cylinder at a position above the ice crystal quantitative feeder. Compressed air from a compressor is directed through water in a further saturation tank and into a classification pipe through a further nozzle to produce a spray of water particles into the classification pipe from the further feed water tank, and the particle classification pipe separates particles larger than a predetermined size from the spray of water particles and passes the remainder of the water particles into the inner cylinder.
