減圧され中空室1の内外の圧力差が次第に大きくなるが
、或る圧力差に達した時点で略平衡状態を維持する。First, if the electric motor 5 is energized and the rotary blade 6 is rotated,
When the decompression friction heat generation mechanism When this is reached, an approximately equilibrium state is maintained.

擦熱発生部Aにおいて空気の滞留現象が生じ、回転羽根
6との摩擦作用が反覆継続するので、摩擦熱が発生して
次第にその温度が上昇する。The pressure difference between the inside and outside of the hollow chamber 1 in this approximately constant equilibrium state is determined by the magnitude of the rotational suction force of the rotary blade 6 and the size of the gap between the suction port 4 and the rotary blade 6. This is maintained as long as the rotational action of the blade 6 continues. In this equilibrium state, a phenomenon of air stagnation occurs in the frictional heat generating part A within the rotation area of the rotating blade 6, and the frictional action with the rotating blade 6 continues to be repeated, so frictional heat is generated and the temperature gradually rises. do.

一方向に回転させる。By the way, a sub-rotation mechanism Y is provided opposite to the decompression frictional heat generating mechanism The rotating body 7 of this driven rotation mechanism Y is rotated in the same direction.
そして中空室1内の空気を排気して所望の減圧状態、す
なわち、中空室1内外の圧力差がほぼ一定の平衡状態に

動する回転翼車7により該回転翼車7のリング12と羽
根13と吸引口4の内壁とで囲縛される気室14内の気
体が強制的に旋回させられると共に回転させることとな
る。The driven rotation mechanism Y exclusively performs the exhaust action until the air in the hollow chamber 1 is exhausted and a desired reduced pressure state is reached, that is, the pressure difference between the inside and outside of the hollow chamber 1 reaches a substantially constant equilibrium state. After reaching this constant reduced pressure state, the air chamber 14 is surrounded by the ring 12 of the rotary impeller 7, the blades 13, and the inner wall of the suction port 4, which is driven by the rotation of the rotating body a. The gas inside is forced to swirl and rotate.
この強制的に旋回作用を受ける気室14内の加熱気流は
、強制旋回対流案内機構Zにより案内板20と傾斜板1
9とで形成される空間部に、規制板21によって旋回流
を附勢されながら導入されさらに中空室1の外周内壁に
向って吐出されるものである。The heated airflow in the air chamber 14 subjected to this forced swirling action is transferred to the guide plate 20 and the inclined plate 1 by the forced swirling convection guide mechanism Z.
The swirling flow is introduced into the space formed by the regulating plate 21 and is further discharged toward the outer peripheral inner wall of the hollow chamber 1.
一方、従動回転機構Yは回転翼車7の回転により一体回
転する回転羽根8の作用で該回転羽根8の右方に位置す

機構Zの働きにより中空室1内の気流は、外周方向から
右方向に向かい中央部分から左方向に向う強制的な対流
作用と、渦巻状の旋回作用(渦巻作用とも認められる)
とを奏することができる。On the other hand, in the driven rotation mechanism Y, the airflow located to the right of the rotary vane 8 is forcibly sucked to the left by the action of the rotary vane 8 which rotates integrally with the rotation of the rotary impeller 7, and the airflow is forcibly sucked to the left by the suction vane 18 of the ring 12. In exchange for the suction effect, the air is forcibly sent to the friction heat generation part A of the rotary vane 6 of the decompression friction heat generation mechanism x, where it is replaced with the airflow that has already risen and is generated by the rotary impeller 7 as described above. It is discharged forming a swirling flow to the right. Therefore, due to the functions of the bottom rotation mechanism Y and the forced swirling convection guide mechanism Z, the airflow in the hollow chamber 1 is forced to move from the outer circumference to the right and from the center to the left. Action (also recognized as spiral action)
can be played.
このように中空室1内の空気圧が回転羽根6の回転によ

方向から右方に送給させ一旦右行した後中空室1の右側
外周より中心に向って移行する気流の対流作用を強制的

を含有する空気は吸引口4から排出されて有効な水分抽
出作用すなわち乾燥作用が行われる。したがって、中空
室1内の載層板30上の被乾燥物は水分の遊離作用を受
けて急速な乾燥作用を受けることができる。In this manner, when the air pressure inside the hollow chamber 1 is under the pressure reducing effect due to the rotation of the rotary vane 6, the swirling airflow is sent from the outer circumferential direction to the right, and after once moving to the right, it is moved from the right outer circumference of the hollow chamber 1 to the center. Since the convection effect of the airflow moving toward the chamber 1 is forcibly generated, the temperature inside the chamber 1 can be uniformized rapidly to a desired set temperature. In addition, the convecting and overflowing airflow uniformly enters and acts on the battle laminates 30 arranged in multiple stages, so that the whole can be heated under reduced pressure. By the way, when the material to be dried is housed, some of the vaporized moisture is discharged to the outside through the suction port 4, but if outside air is introduced using the outside air introduction mechanism B, the outside air will flow into the outside air introduction chamber of the hollow chamber 1. Sent within 26 days,
The air that diffuses into the hollow chamber 1 through the large number of holes 25 of the diffuser plate 24 and instantly contains vaporized moisture corresponding to the supplied air is exhausted from the suction port 4 for effective moisture extraction. That is, a drying effect is performed. Therefore, the material to be dried on the laminated plate 30 in the hollow chamber 1 can undergo a rapid drying action due to the release of moisture.
なお、一回の外気導入作用で乾燥が不十分の場合は、一
旦開閉弁23を閉じ、再び減圧平衡状態に保って加熱す
ることにより、被乾燥物を再び加熱し、乾燥を促がし、
所望時間後外気導入機構Bを働かせることにより同様の
作用効果を奏することができる。In addition, if drying is insufficient with one action of introducing outside air, the opening/closing valve 23 is temporarily closed and heating is performed again while maintaining a reduced pressure equilibrium state, thereby heating the material to be dried again and promoting drying.
Similar effects can be achieved by activating the outside air introduction mechanism B after a desired period of time.

は勿論である。If the outside air introduction mechanism B is operated intermittently in this way,
The drying effect of the material to be dried, which is placed in a reduced pressure equilibrium state, can be accelerated in an extremely short period of time. Furthermore, although the hollow chamber 1 is shown in the shape of a horizontal rectangular parallelepiped, this shape is not specified in any way, and it goes without saying that the hollow chamber 1 may be turned vertically by 90 degrees to have a cylindrical structure.

れる。In the case of a horizontal rectangular parallelepiped shape as shown in the figure, curved surfaces may be formed at the four corners of the four circumferences to gradually reduce the flow resistance of the swirling laminar flow. Although one embodiment of the present invention has been described above, the driven rotation mechanism Y and the forced swirl flow guide mechanism Z may be omitted except for the reduced pressure frictional heat generation mechanism X. As described above, this invention suctions and exhausts the air in a sealed hollow chamber by the rotational action of a rotating body, maintains the hollow chamber in a reduced pressure state, and maintains the pressure difference between the inside and outside in a substantially constant equilibrium state. By continuing the rotating action of the rotating body and generating frictional heat by the frictional action between the rotating body and the air, the material to be dried in the hollow chamber 1 can be heated and dried at a desired temperature, and the opening/closing valve of the outside air introduction mechanism can be operated manually or automatically. By opening, the outside air enters the outside air introduction chamber, and once the rapid inflow of air into the hollow chamber is blocked by the diffusion plate, the air is uniformly distributed from the entire area of the diffusion plate through the many holes, and the nozzle action is applied. As a result, vaporized moisture is removed from the suction port by the amount of air that diffuses into the hollow space.

In particular, by repeating the outside air introduction action by the outside air introduction mechanism at desired intervals, a more efficient drying action can be performed.
したがって、この発明によれば各種被乾燥物を高品質に

It has the characteristics of being able to perform a uniform and effective heating action and effectively performing all kinds of drying actions.
