本考案は、合板製品の素材となる単板のように

布などの乾燥装置に関するものである。[Detailed description of the invention] [Industrial field of application] The present invention relates to a drying device for drying plate-like materials containing a lot of water, such as veneers used as materials for plywood products, or sheet-like woven fabrics. It is something.

In conventional drying equipment, most of the drying equipment is constructed in the form of an airtight container, with the exception of the feeding and unloading parts of the drying material into the equipment, with a heat-retaining plate filled with heat insulating material, etc. It is equipped with a transport mechanism that transports the material to be dried at an appropriate speed within the device, and a fan that circulates hot air heated to high temperature by a heat exchanger using steam or the like as a heat source while blowing it onto the material to be dried, and a ventilation path. Devices constructed from the above are widely used.

か、乾燥能率向上の目的で単板搬送路の上下に、
新たに複数の放熱管を配備したものである。 Conventional examples of these include, for example, a veneer veneer dryer disclosed in Japanese Patent Application No. 58-84546 (Japanese Unexamined Patent Publication No. 59-845).
208381). This invention consists of a veneer transport mechanism (endless transport belt), a heater that heats the air inside the machine,
In addition to technologies used in conventional veneer drying equipment, such as a blower for circulating heated hot air and ventilation channels, there are
It is equipped with multiple new heat dissipation tubes.
従来の乾燥装置は、乾燥効率アツプをねらつて
各種の改良工夫が加えられ、その点では略完成の

自体が厖大なスペースを占有し、前記従来例の中

のである。
Conventional drying equipment has undergone various improvements with the aim of increasing drying efficiency, and in that respect it feels like it has almost reached the stage of perfection. However, the device itself occupies a huge amount of space, and among the conventional double circulation dryers mentioned above, it is not uncommon to have a total length of about 30 meters.
また従来の乾燥装置においては被乾燥物の均一
な乾燥が困難であつた。特に天然木から取得する
単板は含有水分が辺材、芯材等によつても異なり
平均した仕上がり含水率に乾燥することは至難の
わざであり、いきおい乾燥工程経過後の被乾燥物
中、渇きの甘いもの(あまり乾いていないもの)
を選別して再乾燥するといつた余分な作業が繰り
返されていたのである。 Furthermore, in conventional drying apparatuses, it has been difficult to uniformly dry objects to be dried. In particular, the moisture content of veneer obtained from natural wood varies depending on the sapwood, core material, etc., and it is extremely difficult to dry it to an average finished moisture content. Something sweet for your thirst (something that isn't very dry)
The extra work of sorting and re-drying was repeated.
さらに大型の乾燥装置は熱エネルギーを大量に
消費するが、装置が大型化するほど大気への放熱
面積も拡大され、石油、その他熱エネルギー消費
も無駄が増える結果になるのである。 Furthermore, large drying equipment consumes a large amount of thermal energy, and the larger the equipment, the larger the area for heat radiation to the atmosphere, resulting in increased waste in oil and other thermal energy consumption.

る。
The present invention uses far-infrared rays with a wavelength of 2.5 micrometers or more on the outer circumferential surface of the rollers, in contrast to the conventional method in which the objects to be dried are continuously conveyed by a conveyance mechanism using rollers and dried by hot air circulating inside the machine. It is characterized by being coated or welded with a powdered far-field external radiation emitter that emits.

乾燥されるが、同時に該ローラーも熱風を受けて
昇温し、その外周面に塗着した遠赤外線放射物を
も加熱し遠赤外線を効果的に上下に発散して搬送
中の被乾燥物を照射することになるのである。 In this invention, the material to be dried is transported by a transport mechanism (roller) and dried by being exposed to hot air circulating inside the machine. At the same time, the roller also receives hot air and heats up, causing far-infrared rays to coat its outer surface. The radiant is also heated and far-infrared rays are effectively emitted upward and downward to irradiate the material to be dried during transport.
一般に高分子化合物など殆どの有機物質や無機
物の一部は、波長2.5ミクロンメートル以上の長
波長域に同調点を有しており、従ってその波長域
の電磁波(遠赤外線)を浴びた物体は電磁波共鳴
現象を惹き起こすのである。 In general, most organic substances such as polymer compounds and some inorganic substances have a tuning point in a long wavelength range of 2.5 micrometers or more, and therefore objects exposed to electromagnetic waves (far infrared rays) in that wavelength range receive electromagnetic waves. This causes a resonance phenomenon.
従つて搬送されながら搬送ローラーから遠赤外
線を照射された被乾燥物は、電磁波共鳴現象を惹
起して自己発熱し表面と内部の温度差が急速に縮
まり、同時に内部の水分分布が均一化されて、む
らのない均一な乾燥が遂行されることになる。 Therefore, the material to be dried, which is irradiated with far infrared rays from the transport rollers while being transported, causes an electromagnetic resonance phenomenon and self-heats, rapidly reducing the temperature difference between the surface and the inside, and at the same time making the internal moisture distribution uniform. This results in even and uniform drying.
すなわち、熱風浴と遠赤外線浴の両者によつて
乾燥が促進されるために、従来装置に比べ装置全
体がコンパクトにおさまり、さらに比較的低温の
熱風循環により効率的な乾燥が推進されることに
なるのである。 In other words, because drying is promoted by both the hot air bath and the far-infrared rays bath, the entire device is more compact than conventional devices, and the relatively low-temperature hot air circulation promotes efficient drying. It will become.

方向へ進のである。 17 is a valve 3 that stops heat sources such as steam.
3 is a heat exchanger constituted by a fan heater or the like. Therefore, the air energized by the fan 13 is heated by passing through the heat exchanger from arrow P to Q. The hot air continues to flow down the ventilation duct 15 from arrow R to S, and then from arrow S to T against the direction of transport of the material to be dried.
It's about moving in the right direction.

な作用効果を発現できるのである。 In addition, in this example, the circulation direction of the hot air is
Although we have described in detail the so-called vertical hot air circulation type drying device in which the hot air circulates parallel to the direction of transport of the material to be dried, we will also discuss a hot air cross circulation type drying device in which the hot air circulates perpendicular to the direction of transport of the material to be dried. can also produce similar effects.
