A valve body 30 is attached to and detached from the valve seat 29 from the lower surface side, and the valve body 30 is constantly urged by a spring 31 in a seating direction. The backflow prevention mechanism 27 is opened by the pressure difference between the inside and outside only while the dry air is supplied into the hold 2, and discharges the air in the hold 2 to the outside.

Next, the operation of the present embodiment will be described. When the grain-like grains 3 such as maize are to be scattered and transported in the hold 2, first, with the hatch cover 6 opened, the grain-like grains 3 are loaded into the hold 2 from the hold mouth 4. After the loading is completed, the hatch cover 6 is closed. Then, in this state, the dehumidifier 9 is started.

When the dehumidifier 9 is started, the dry air from the dehumidifier 9 is sent to the hold air nozzle 7 through the supply pipe 11, and a part of the dry air is obliquely downward from each discharge hole 13. It is discharged into.
