<p>A device for supplying granular material (11) has: a guide cylinder (18) in which a plurality of gas-suction holes (28) for guiding inside gas to the outside are formed, and which guides a granular material; a filter (29) provided on the portion in which the gas-suction holes of the guide cylinder are formed, and adapted for allowing the flow of gas inside the guide cylinder to the outside through the gas-suction holes and adapted for preventing leakage to the outside; a nitrogen-gas-supplying device (27); a rotating shaft (21) for rotating inside the guide cylinder; and a blade (22) provided on the rotating shaft, the blade rotating in the guide cylinder by rotation from the rotating shaft and transporting the granular material. The rotating shaft is provided with: an auger (19) in which are formed a nitrogen-gas-supplying channel (23) for guiding inert gas provided by the nitrogen-gas-supplying device, and a gas-supply port (26) through which inert gas guided by the nitrogen-gas-supplying channel is discharged and then included in the granular material; and an air and gas suction device (79) for suctioning gas inside the guide cylinder to the outside of the guide cylinder.</p> |
