Patent number: 5062279Abstract: An artificial snowfall system comprises a snowfall room (2) in which are properly disposed a snow catching element (4) made of materials excellent in gas permeability and an atomizer unit (8) for ejecting atomized particles of liquid into the room (2). The atomized particles are frozen by heat exchange with ambient air within the room (2). The ambient air is kept at a temperature of below a freezing point of the liquid and forms an air flow passing through the snow catching element (4). The air flow causes the frozen particles to be deposited on one side of the catching element (4) to form a snow layer thereon. A beater element (9) for beating the other side of the catching element (4) is oppositely disposed from the other side to have the snow layer separated from the catching element (4). The thus separated snow layer creates artificial snowfall in the room (2).Type: GrantFiled: February 4, 1991Date of Patent: November 5, 1991Assignees: Kabushikigaisha Toyo Seisakusho, Marubeni KabushikigaishaInventors: Ichiro Kawashima, Mitsuo Seki, Isao Hirano
