Document Type and Number:
WIPO Patent Application WO/2001/042725
Kind Code:
A1
Abstract:
A constant-rate, force-feed artificial snow making machine which is an air blowing crusher for eliminating variations in ice lump supply amount to eliminate variations in ice-snow particle size and ice-snow stuck in a casing and for effectively using blown air to discharge ice-snow to distant locations as artificial snow, the snow making machine comprising; a constant-rate ice lump supply machine (1) having a casing (3) provided in the upper portion thereof with an ice lump inlet (4) for receiving ice lumps (2), rotary vanes (8) rotating within the casing (3) to supply ice lumps (2) at a constant rate, and an ice lump outlet (5) provided in the lower portion of the casing (3); and an air blowing crusher (11) having a casing (13) provided in a side surface thereof with an air blowing tube inlet (10) of an air blowing tube (9) for receiving ice lumps (2) supplied from the ice lump supply machine (1) along with blown air (12), rotary vanes (15) provided within the casing (13) and for crushing ice lumps (2) into ice-snow (18), and a blown air exhaust port (19) provided in a side surface opposite to the air blowing tube inlet (10) of the casing (13) and for discharging the obtained ice-snow (18) as artificial snow (20); characterized in that an ice lump receiving port (14) of the crusher (11) is continuously provided to the ice lump outlet (5) of the ice lump supply machine (1) via the air blowing tube (9).
