特許文献１に記載された乾燥装置は、横置きの筒状を有し両端が蓋体で閉塞された乾燥処理容器を備えており、該乾燥処理容器の一端の蓋体の上部には被乾燥物を投入するための供給口が設けられ、又、他端の蓋体の下部には加熱・乾燥された乾燥物を取り出すための排出口が設けられている。乾燥処理容器には、該乾燥処理容器の軸中心に位置するように蓋体を貫通して配置した回転軸と、乾燥処理容器内の回転軸に固定したプレート状の複数の撹拌部材とからなる撹拌装置が設けられている。更に、乾燥処理容器の外部に突出した回転軸には、減速機構を介して撹拌モータが接続されている。   The drying apparatus described in Patent Document 1 includes a drying processing container having a horizontally-placed cylindrical shape and closed at both ends with lids, and an upper portion of the lid at one end of the drying processing container is to be dried. A supply port is provided for charging the product, and a discharge port is provided at the lower part of the lid at the other end for taking out the heated and dried product.

しかしながら、上記従来の乾燥装置の撹拌部材は、回転軸の回転によって供給口から投入された被乾燥物を徐々に排出口側へ向かって移動させるように構成されているため、被乾燥物を排出口側へ向かって移動させないで撹拌することができないという不都合がある。例えば、乾燥にある程度の時間を要する場合は被乾燥物を滞留させた状態で撹拌する必要あるが、上記従来の乾燥装置はそれができない。このため撹拌部材の回転速度を遅くして対応するしかないが、適切な回転速度を設定することも簡単ではない。
また、撹拌部材の回転速度を遅くすると、被乾燥物の撹拌、破砕が不十分となるおそれもある。
本発明は上記従来の問題点に着目して為されたものであり、乾燥処理容器の所定の領域に被乾燥物を滞留させた状態で撹拌することができ、しかも乾燥処理容器内の被乾燥物を速やかに排出口から排出させることができる乾燥装置の提供を、その目的とする。 However, since the stirring member of the conventional drying apparatus is configured to gradually move the material to be dried input from the supply port toward the discharge port side by the rotation of the rotating shaft, the material to be dried is discharged. There is an inconvenience that stirring cannot be performed without moving toward the outlet side. For example, when a certain amount of time is required for drying, it is necessary to stir while the material to be dried is retained, but the conventional drying apparatus cannot do so. For this reason, the rotational speed of the stirring member can only be reduced, but it is not easy to set an appropriate rotational speed.
Moreover, when the rotation speed of the stirring member is slowed, there is a possibility that stirring and crushing of the material to be dried may be insufficient.
The present invention has been made by paying attention to the above-mentioned conventional problems, and can stir the object to be dried in a predetermined region of the drying processing container, and can be dried in the drying processing container. It is an object of the present invention to provide a drying apparatus that can quickly discharge an object from a discharge port.

前述のように乾燥処理容器７の円弧状面９、垂直面１１は加熱されているので、動植物性残渣Ｋが加熱される。
また、モータ２５を正転させ駆動軸２７と共に回転軸２３を正転駆動させる。すなわち回転軸２３を矢印Ｓで示す正転方向へ駆動させて、この回転軸２３と共に撹拌部材２９が正転方向Ｓへ回転駆動させる（図８参照）。 As described above, since the arc-shaped surface 9 and the vertical surface 11 of the drying treatment container 7 are heated, the animal and plant residue K is heated.
Further, the motor 25 is rotated in the forward direction to drive the rotation shaft 23 in the forward direction together with the drive shaft 27. That is, the rotation shaft 23 is driven in the normal rotation direction indicated by the arrow S, and the stirring member 29 is rotated in the normal rotation direction S together with the rotation shaft 23 (see FIG. 8).

撹拌部材２９が正転方向Ｓへ回転駆動すると、撹拌面４１、４３が動植物性残渣Ｋをかき分けるように動作する。前述のように撹拌面４１、４３は排出口１９側を基準として互いに逆向きとなるように傾斜し、傾斜角度が同じに設定されており、更に頂部４４は回転軸２３の正転方向Ｓへ向くと共に頂部４４の延長線が回転軸２３に直交しているので、図８に示すように動植物性残渣Ｋは撹拌面４１、４３に沿ってＨ方向とＦ方向（Ｈ方向と反対方向）へ移動させられる。撹拌面４１と撹拌面４３は同じ面積に設定されているので、撹拌面４１と撹拌面４３によって移動させられる動植物性残渣Ｋの量はほぼ等しい。従って、動植物性残渣Ｋは移動しないで、乾燥処理容器７内の所定の領域内において動植物性残渣Ｋを滞留させた状態で撹拌することができる。   When the stirring member 29 is rotationally driven in the forward rotation direction S, the stirring surfaces 41 and 43 operate so as to scrape the animal and vegetable residue K. As described above, the stirring surfaces 41 and 43 are inclined so as to be opposite to each other with respect to the discharge port 19 side, the inclination angles are set to be the same, and the top portion 44 is directed in the forward rotation direction S of the rotating shaft 23. Since the extension line of the top portion 44 is perpendicular to the rotation axis 23, the animal and plant residue K is directed along the stirring surfaces 41 and 43 in the H direction and the F direction (the direction opposite to the H direction) as shown in FIG. Moved. Since the stirring surface 41 and the stirring surface 43 are set to have the same area, the amount of the animal and plant residue K moved by the stirring surface 41 and the stirring surface 43 is substantially equal. Therefore, the animal and plant residue K does not move and can be stirred while the animal and plant residue K is retained in a predetermined region in the drying treatment container 7.

また、撹拌部材２９には４枚の破砕羽根５１は設けられており、動植物性残渣Ｋを確実に破砕することができる。更にスクレーパー４９によって乾燥処理容器７の円弧状面９に付着した動植物性残渣Ｋが掻き取られるので、動植物性残渣Ｋが円弧状面９に付着するのを防止することができる。   Moreover, the crushing blade | wing 51 of 4 sheets is provided in the stirring member 29, and the animal and vegetable residue K can be crushed reliably. Furthermore, since the animal and plant residue K attached to the arcuate surface 9 of the drying container 7 is scraped off by the scraper 49, the animal and plant residue K can be prevented from adhering to the arcuate surface 9.

一方、加熱された動植物性残渣Ｋから蒸気が発生する。前述のように乾燥処理容器７内は減圧されているので水の沸点が下がり、動植物性残渣Ｋに含まれる水を効率よく蒸発させることができる。
動植物性残渣Ｋから発生した蒸気は屋根体５３の下端部５９と排水樋６１の内側立ち上り部６３との隙間を通って、角筒６７、６９の下側の空間に流入する。前述のように冷却パイプ７１内を流れる冷却水によって冷却パイプ７１、角筒６７、６９が冷却されているので、角筒６７、６９の下側の空間に流入した蒸気が冷却されて、結露して水滴となる。この水滴は図５に示すように屋根体５３の下端部５９の上面に溜まり、更にこの上面から排水樋６１へ流れ落ちる。
排水樋６１内の水は真空ポンプ８７によって吸引されて吸引管６２を通り、冷却塔８１へ送られて冷却水として使用される。 On the other hand, steam is generated from the heated animal and vegetable residue K. As described above, since the inside of the drying treatment container 7 is depressurized, the boiling point of water is lowered, and water contained in the animal and plant residue K can be efficiently evaporated.
The steam generated from the animal and vegetable residue K flows into the space below the rectangular tubes 67 and 69 through the gap between the lower end 59 of the roof 53 and the inner rising portion 63 of the drainage basin 61. Since the cooling pipe 71 and the square tubes 67 and 69 are cooled by the cooling water flowing through the cooling pipe 71 as described above, the steam flowing into the space below the square tubes 67 and 69 is cooled and condensed. Water drops. As shown in FIG. 5, the water droplets accumulate on the upper surface of the lower end portion 59 of the roof body 53 and further flow down from this upper surface to the drainage basin 61.
The water in the drain 61 is sucked by the vacuum pump 87, passes through the suction pipe 62, is sent to the cooling tower 81, and is used as cooling water.

動植物性残渣Ｋの乾燥が終了した場合には、蓋体２１を開けて排出口１９を開放してから、モータ２５を逆転させ駆動軸２７と共に回転軸２３を逆転駆動させる。すなわち回転軸２３を矢印Ｇで示す逆転方向へ駆動させて、回転軸２３と共に撹拌部材２９が逆転方向Ｇへ回転駆動する（図９参照）。
撹拌部材２９が逆転方向Ｇへ回転駆動すると、搬送面４５が動植物性残渣Ｋに接触する。前述のように搬送面４５は回転軸２３を基準としてＨ方向へ下がるように傾斜し、しかも先端部４７が回転軸２５の逆転方向Ｇを向いているので、図９に示すように動植物性残渣Ｋは搬送面４５にガイドされてＨ方向へ移動させられる。従って、動植物性残渣Ｋを排出口１９から排出することができる。
このように乾燥装置１では１つの撹拌部材２９によって回転方向を変えるだけで、乾燥処理容器７の所定の領域内において動植物性残渣Ｋを滞留させた状態で撹拌することができ、しかも乾燥処理容器７内の動植物性残渣Ｋを速やかに排出口１９から乾燥処理容器７外へ排出させることができる。 When the drying of the animal and vegetable residue K is completed, the lid 21 is opened and the discharge port 19 is opened, and then the motor 25 is rotated in the reverse direction and the rotary shaft 23 is driven in the reverse direction together with the drive shaft 27. That is, the rotating shaft 23 is driven in the reverse direction indicated by the arrow G, and the stirring member 29 is rotated in the reverse direction G together with the rotating shaft 23 (see FIG. 9).
When the stirring member 29 is rotationally driven in the reverse rotation direction G, the transport surface 45 comes into contact with the animal and vegetable residue K. As described above, the conveying surface 45 is inclined so as to be lowered in the H direction with respect to the rotating shaft 23, and the tip 47 is directed in the reverse direction G of the rotating shaft 25. Therefore, as shown in FIG. K is guided by the conveyance surface 45 and moved in the H direction. Therefore, the animal and plant residue K can be discharged from the discharge port 19.
As described above, in the drying apparatus 1, the animal and plant residue K can be stirred in a predetermined region of the drying processing container 7 only by changing the rotation direction by the single stirring member 29, and the drying processing container can be stirred. 7 can be quickly discharged out of the drying treatment container 7 from the discharge port 19.
