When both are closed, a passage is formed directly from the dry air exhaust chambers 9 and 10 to the suction fan 19. When the switching valve 26 is opened and the switching valve 25 is closed, a passage from the drying chamber lower grain collecting room 13 directly to the suction fan 19 is formed. When the switching valve 26 is closed and the switching valve 25 is opened,
A passage is formed from the grain collecting room 13 in the lower part of the drying room to the suction fan 19 via the dust collection box 20, so that it is possible to switch between these three modes.
（作用） 次に作用を述べる。(effect) Next, we will discuss the effect.
ａ 切替弁２５，２６をともに閉めることにより
乾燥風排気室９，１０から直接吸引フアン１９
に至る通路を形成した場合。a. By closing both the switching valves 25 and 26, the suction fan 19 is removed directly from the dry air exhaust chambers 9 and 10.
If a passageway is formed that leads to .

する。 When the raw grains are made to flow into the humidity control tank 15 using the bucket elevator 17, the flow-down drying chambers 5, 6 and the humidity control tank 15 are filled with the raw grains. Raw grain has a high moisture content, generates little dust, and is difficult for wind to pass through, so switching valve 2 is
5 and 26 are both closed, and then the drying air is sucked directly from the drying air exhaust chambers 9 and 10 to strongly suck it.
この状態でバーナー１８を点火し、回転バル
ブ１１，１２を回転させ、吸引フアン１９を回

のである。 Partially dried grains in the drying chambers 5 and 6 fall onto the grain collecting chamber 13 in the lower part of the drying chamber, and are carried by the screw conveyor 14 to the bucket elevator 1.
7, the grains are fried, stacked on top in the humidity control tank 15 by the spiral conveyor 16, and circulated. When the top-heaped grains enter the down-flow drying chambers 5 and 6 again and are exposed to the second drying air, the drying progresses considerably, which naturally increases the amount of dust generated. Therefore, when the switching valves 25 and 26 are switched to the position shown by the solid line, the air sucked from the dust suction port 21 flows into the dust collection box 20 through the hollow pipe 22, and the dust is removed within the dust collection box 20. Only air is sucked and exhausted through the hollow pipe 24.
ｃ 切替弁２６を開き切替弁２５を閉じることに
より乾燥室下部集穀室１３から直接吸引フアン
１９に至る通路を形成する場合。c. A case in which a passage is formed directly from the drying chamber lower grain collecting room 13 to the suction fan 19 by opening the switching valve 26 and closing the switching valve 25.
塵埃を排出してもよいような場所に乾燥機が

弁２５を閉じて集塵箱２０に至る風路を遮断
し、吸塵口２１からの乾燥風を吸塵口２３を介
して吸引フアン１９により吸引排除するので、
長時間の連続運転を可能にする。 When the dryer is installed in a place where dust can be discharged, the switching valve 26 is opened and the switching valve 25 is closed to block the air path leading to the dust collection box 20 and drying from the dust suction port 21 is performed. Since the wind is sucked and removed by the suction fan 19 through the dust suction port 23,
Enables continuous operation for long periods of time.
