PURPOSE: To effectively accumulate ice and snow on smaller space in a ski slope, without scattering them.

CONSTITUTION: A cyclone type ice storage equipment has an outer casing 25 formed in domed and cylindrical shape. At the lower part of the outer casing 25, a flexible bellows part 26 is provided and a weight ring 26a for the outer casing 25 is provided around an opening part thereat. Inside the outer casing 25, a space 29 for storing an ice-accumulating bag 30 is provided, the ice- accumulating bag 30 deformably formed so as to fit into the inside of the outer casing 25 is provided in the space 29 and an ice-accumulating space 31 is provided inside the ice-accumulating bag 30. At the upper part of the outer casing 25, a hole 27b and an air-exhausting hole 30a are respectively formed so as to pierce the outer casing 25 and the ice-accumulating bag 30. Furthermore, at the upper side of the outer casing 25, a duct 23 for supplying ice and snow is provided so as to pierce the outer casing 25 and the ice-accumulating bag 30.
