A method of discharging artificial snow (S) from a snow making facility (20) including an evaporator vessel (1) and producing snow by means of the technique of freezing water under vacuum pressure by maintaining a vacuum pressure in the evaporator vessel and producing water vapor that absorbs the latent heat of vaporization from the water, whereby the water temperature drops until it freezes and reaches the super cooling temperature that corresponds to the existing vacuum pressure, wherein produced snow is withdrawn from a bottom portion (1A) of the evaporator vessel by means of a first pipe screw conveyor (4), the withdrawn snow is conveyed from the first screw conveyor through a controlled first valve (6) and into a second pipe screw conveyor (5) and snow is discharged to the atmosphere from the second screw conveyor through a controlled second valve (7). A facility for producing artificial snow as well as a method for controlling the quality of produced artificial snow are also provided.
A method of discharging artificial snow from a snow making facility including an evaporator vessel and producing snow by a technique of freezing water under vacuum pressure by maintaining a vacuum pressure corresponding to the boiling point of water at a temperature below 0° C. in the evaporator vessel and producing water vapor that absorbs the latent heat of vaporization from the water whereby the water temperature drops until it freezes and reaches the super cooling temperature that corresponds to the existing vacuum pressure, the method comprising:
A snow making facility for discharging artificial snow and including an evaporator vessel, a vacuum generating device being connected to the evaporator vessel for producing and maintaining a vacuum pressure therein and to a condenser, a water supply for distributing water in the evaporator vessel through a water supply line and at least one water nozzle and means for discharging snow produced in the evaporator vessel therefrom, the snow making facility comprising:
