Abstract
An artificial snow making apparatus has a vertical inner cylinder, an outer tank around said inner cylinder, an air velocity adjusting duct connected between the top and an intermediate portion of the inner cylinder for causing air to flow therethrough from the top of the inner cylinder and to flow upwardly in the inner cylinder. The duct has a fan therein for adjusting the velocity of the air flowing therethrough for thereby adjusting the velocity of the air flowing in the inner cylinder. A cloud making machine and a seeding device are connected directly to the vertical inner cylinder at positions between the top and the intermediate portion. A cooling unit is provided for cooling air in the outer tank, thereby cooling the inner cylinder. A blower apparatus draws air from the outer tank, adjusts the temperature to the temperature of the air inside the inner cylinder and directs it downwardly into the inner cylinder below the intermediate portion. A temperature/humidity control apparatus draws air from the outer tank, adjusts the temperature and humidity thereof to a temperature and humidity higher than the temperature and humidity of the air in the upper part of the inner cylinder…
