Zusammenfassung:PROBLEM TO BE SOLVED: To stably maintain the moisture content of grain by reducing giving-receiving of moisture between the grain and pneumatic transport air in the middle of pneumatic transport. SOLUTION: This device has a transport pipe 16 for pneumatically transporting the grain 10, a blower 18 for sending force feed air in the upstream side of this transport pipe 16, a grain supplier 12 for supplying the grain 10 to the upstream side of the transport pipe 16, a cyclone 30 arranged on the downstream side of the transport pipe 16, an air returning pipe 34 for circulating used air separated by the cyclone 30 to the blower 18, and a controller 50 capable of adjusting a circulating quantity of the used air on the basis of humidity and temperature of outside air.
