ARTIFICIAL SNOWFALL DEVICE AND METHOD

摘要

PROBLEM TO BE SOLVED: To switch a spreading device without providing an ice storage and without stopping the operation of an ice maker. SOLUTION: Ice snow 60 that is made by an ice maker 2 is supplied to conveyors 6 and 7. The ice snow 60 is supplied to a feeder 8 by the conveyors 6 and 7. A fixed amount of ice snow 60 is supplied form the feeder 8 to an ice snow transport pipe 3 being laid at snow play facilities. A spreading device 4 for switching a snow ice spreading region is arranged in the middle of the ice snow transport pipe 3. When switching the spreading device 4, the amount of transport of the conveyors 6 and 7 is controlled by a means for controlling the amount of transport, and the ice snow 60 is stored in the conveyors 6 and 7, thus the need for providing an ice storage is eliminated, and the spreading device can be switched without stopping the operation of the ice maker.
