Abstract
An artificial snow making apparatus has a vertical inner cylinder having an opening at the lower end thereof, an air velocity adjusting duct connected between the top of the inner cylinder and a point near the lower end thereof and having an air blower therein for adjusting the velocity of air in the duct for thereby controlling the velocity of air inside the inner cylinder, an outer tank around the inner cylinder and having a cooling unit therein for cooling the inner cylinder and a cloud-forming vapor generator and an ice crystal seed generator connected to the inner cylinder for causing artificial snow to be generated in the inner cylinder and fall in the inner cylinder. A wet snow forming member is disposed below the opening at the lower end of the inner cylinder and directs air downwardly, and a blower draws in air, and a humidifier-heater adjusts the temperature and humidity of the drawn in air to a level higher than those of the air inside the inner cylinder to form warm and wet air, and then blows the warm and wet air into the wet snow forming member wherein it is directed downwardly to wet the snow falling through the opening from inside the inner cylinder to change the sn…
