のとしては以下に述べるようなものがある。(Prior art) Heating of powder particles with a size of 30 iris or less is often carried out for drying purposes, and the following methods are known in the past: .

外線乾燥器もあるが、被照射物の吸収波長帯が合致すれ
ば効率的に加熱できるが1表層のみの加熱状態となるた
め塗膜などの薄物以外は均一な加熱ができない。These include box-type dryers, single-rotation dryers, air wave dryers, fluidized flow dryers, groove-type stirring dryers, and vacuum dryers. All of these basically have a configuration in which air is heated, hot air is sent, and the powder is heated with the hot air. Since indirect heating does not directly heat the granular material with a heat source, there are problems in that thermal efficiency is poor, it takes time, and the gaps between the granular materials act as a heat insulating layer, making heating inside the material slow. There is also an infrared dryer, but if the absorption wavelength band of the irradiated object matches, it can heat efficiently, but only one surface layer is heated, so it cannot uniformly heat objects other than thin objects such as paint films.
近年上記生物性被処理材の場合、遠赤外線領域に吸収波

提案されている。In recent years, it has been found that the above-mentioned biological materials to be treated have an absorption wavelength band in the far-infrared region and can be efficiently heat-treated by far-infrared heating, and a heating type using far-infrared rays has been proposed.

れている。However, in the case of this far-infrared heating, parts that are not directly irradiated with far-infrared rays, such as those at the bottom of the layered powder or granular material, may not be heated, or the surface layer may be overheated. As an improvement for this purpose, for example, JP-A-63-291
548, Japanese Unexamined Patent Publication No. 62-158981, and Japanese Utility Model Application No. 62-97489 are known.
最初のものは、コンベア上方に熱源を配置して加熱する
ものであり、粉粒体全体を満遍なく加熱させるため、コ
ンベア自体を振動させて粉粒体を攪拌する構造とされて
いる。すなわち、振動によって攪拌して加熱している。The first one heats the powder by placing a heat source above the conveyor, and has a structure in which the conveyor itself vibrates to stir the powder in order to evenly heat the entire powder. That is, it is stirred and heated by vibration.
このようにコンベア自体を振動させるものでは粉粒体の
種類によっては十分な撹拌が困難であり、かつ十分な能
力を有する振動コンベア自体は調節が複雑で高価である
という問題がある。With such a conveyor that vibrates itself, it is difficult to sufficiently agitate some types of powder and granules, and a vibrating conveyor itself that has sufficient capacity has the problem of being complicated to adjust and expensive.

ーで回転させて攪拌させながら移動させ同時に加熱する
ものである。このようなスクリューコンベアを用いたも
のは、十分に撹拌され、全体が均一に加熱されるものの
、きわめて高価になるという問題があった。An intermediate method uses a screw conveyor in which a rotating screw is placed in a cylindrical transport case, and the powder and granules are moved while being rotated by the screw and stirred, and are heated at the same time. Although the method using such a screw conveyor provides sufficient stirring and uniform heating of the entire product, there is a problem in that it is extremely expensive.

で簡単な乾燥には適するが、加熱温度を制御するなどと
いうことができず、使用粉粒体に制限がある。The last one uses the far-infrared radiation plate itself as a heat source as a conveyor, and it dries the powder while running it on the plate fixed at an angle, and at the end it is dropped onto the next plate with a different inclination direction. It is designed to dry by repeatedly running it. Although such a simple structure is suitable for inexpensive and simple drying, it is not possible to control the heating temperature, and there are restrictions on the powders and granules that can be used.

を特徴とするものである。[Structure of the Invention] (Means for Solving i) The first invention provides a far-infrared heating means for heating the powder and granular material on the container above the container which carries the powder and granular material and moves. , and a stirring means for stirring the powder and granular material is arranged on the conveyor, but the stirring means uses a large number of stirring bodies arranged in a long line, and the stirring means is arranged in the longitudinal direction of the arrangement. The stirrer is disposed so as to intersect with the moving direction of the conveyor, and the tip of the agitator is placed close to the upper surface of the conveyor.
I−記攪拌手段は所定の間隔で複数箇所に設けることが
望ましい。It is desirable that the stirring means described in I- be provided at a plurality of locations at predetermined intervals.

に攪拌手段はスクリューコンベアなどで用いられる回転
するスクリューであってもよいのはいうまでもない。It is sufficient that the stirring means is a comb-like long rod with thin stirring bodies arranged at fine intervals of many degrees. The tip of the stirring body may be sharpened, the comb-shaped stirring means may be reciprocated in the longitudinal direction, and the stirring means may be a rotating screw used in a screw conveyor or the like. Needless to say, it's good.
本第2発明は、上記撹拌体を設けたコンベア上方に遠赤
外線加熱手段を設けた加熱部を上下方向に複数段設け、
上段のものから下段のものへ粉粒体が落下するように構
成させたことを特徴とするものである。The second invention provides a plurality of heating sections provided with far-infrared heating means in the vertical direction above the conveyor provided with the agitating body,
It is characterized in that it is structured so that the powder and granules fall from the upper layer to the lower layer.

ことを特徴とするものである。Furthermore, the third invention is characterized in that the plurality of far-infrared heating means of the apparatus having the above-mentioned structure is a rod-shaped heater that rapidly heats the first one, and a planar heater that heats the latter one slowly. It is.
(作用)
粉粒体はコンベアに載せられて定められた速度で移動す
る。その間にコンベアの上方に配置された遠赤外線加熱
手段によって加熱される。(Operation) Powder is placed on a conveyor and moves at a predetermined speed. During this time, it is heated by far-infrared heating means placed above the conveyor.

に出たりながら移動することになる。したがって粉粒体
はコンベア上で攪拌される。すなわち、本発明によれば
粉粒体は攪拌されながら遠赤外線加熱手段によって加熱
される。By the way, in the case of the present invention, the powder and granules transported by the conveyor are piled up on the conveyor to a certain thickness, and the powder and granules move while coming out to the agitation means whose tip is placed close to the conveyor. It turns out. Therefore, the granular material is stirred on the conveyor. That is, according to the present invention, the powder or granular material is heated by the far-infrared heating means while being stirred.
撹拌手段が所定の間隔で複数設けてあればその複数の箇
所で攪拌されることになり、より均一に混合され全体の
粉粒体が満遍なく遠赤外線加熱手段により加熱される。If a plurality of stirring means are provided at predetermined intervals, stirring will be performed at the plurality of locations, and the powder will be mixed more uniformly and the whole powder will be evenly heated by the far-infrared heating means.

的に焼くなどで変質させ、揮発しにくくすることができ
る。その後面状ヒータで所定の加熱温度に保持させれば
、有効成分の揮発をより少なくして乾燥させたり、全体
の変質を防止することができる。When drying by heating, the effective ingredients of substances such as medicinal herbs will volatilize along with the water contained inside the powder.Powder and granules for which volatilization of the active ingredients is inconvenient must be dried. Even when this is necessary, in the past, simply heating was performed, which was undesirable because the amount of the active ingredient evaporated. On the other hand, in the third aspect of the present invention, since the powder is rapidly heated with a rod-shaped heater first, the surface of the powder can be preferentially burnt to change its quality and make it difficult to volatilize. If the heating temperature is maintained at a predetermined temperature using a rear heater, it is possible to dry the active ingredients with less volatilization and to prevent deterioration of the overall quality.

5に落とされ、収納箱24に集積される。The operation of the above example will be explained below. The granular material placed in the hopper 17 is dropped onto the belt 5 in fixed amounts by the rotary blades 18. Since the belt 5 is circulated at a rate of, for example, 0.51 to 5 m/min by a drive motor 13 controlled by an inverter, the powder on the belt moves at that speed. During movement, it is heated by sheet heaters 14, 14, . . . . During this time, when the agitating plate 15 is reached, the tip of the agitating body 16 has reached the upper surface of the belt 5, so that the powder and granules hitting the agitating plate 16 are scraped through between the agitating bodies 16 and 16. That is, it is stirred. After that, when the next stirring plate 15 is reached, the position of the stirring body 16 of this stirring plate is shifted from the position of the stirring body of the previous stirring plate, so it is scraped by the previous stirring plate 15 and becomes streaked. The same applies to the zero-order stirring means in which the mountainous portion of the powder or granular material just hits the stirring body 16, and the peaks and valleys of the streak are exchanged and stirred again. In this way, each time the granular material comes to the position of the stirring plate 15, it is stirred and heated by far infrared rays. Therefore, in this apparatus, not only the powder and granular material stacked on the surface but also the entire material on the belt 5 is heated evenly and uniformly. The heated and dried material is transferred from the end of the belt 5 to the chute 2.
5 and accumulated in the storage box 24.

られるものなら何でもよい。This stirring means 26 has a large number of elongated stirring bodies 28 fixed so as to hang from a shaft 27 slidably attached to the side wall of the housing 2. 27 is made to reciprocate. Sliding gear of this example! 129 uses a link mechanism in which a lever is used to connect a disk pin with a bottle rotated by a motor to the shaft 27, but it is also possible to use a link mechanism in which another rod-shaped object such as a reciprocating piston is continuously reciprocated in its longitudinal direction. Anything you can do is fine.

効果は大きい。If a large number of stirring bodies 28 arranged upright on the belt 5 reciprocate in the width direction of the belt 5 in this way, the powder and granules placed on the belt 5 can be easily stirred. As can be seen, the stirring effect is greater than in the previous example where it remains stationary.

、食品などの乾燥に好適である。In the case of this example having two heating sections, the upper heating section rapidly heats up to a predetermined temperature, and the lower heating section is heated slowly at a predetermined temperature lower than the previous stage. Rapid heating at high temperatures in the upper stage preferentially burns the surface of vegetable chips, such as medicinal herbs and vegetables, to a predetermined temperature, and then slow heating avoids deterioration of the entire structure and prevents volatilization of the active ingredients in the powder. , which only removes moisture slowly. Suitable for drying medicinal herbs, foods, etc.
