[0024] The top of the top plate 31 is connected to a rotating shaft 33, and the top of the rotating shaft 33 passes through the silo 11 through a through hole and is connected to a driving motor 35. The driving motor 35 is installed on the surface of the frame plate 34, and the frame plate 34 is fixed to the top of the silo 11 by bolts.

[0025] The cross section of the polygonal shaft cylinder 32 is designed to be a hexagonal structure, and the sides of the polygonal shaft cylinder 32 are all provided with slots adapted to fit the liquid nitrogen nozzle 22 .
