【発明の詳細な説明】
〔産業上の利用分野〕
ヘドロ、下水汚泥、おから、食品類、反応終了時の染料
など極めて高い含水体の短時間で可能な粉砕乾燥方法と
その装置に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a method and apparatus for crushing and drying highly water-containing substances such as sludge, sewage sludge, okara, food products, and dyes at the end of a reaction in a short time. be.
従来、適当な方法がないので、ヘドロなど天日乾燥やそ
のまま廃棄したり、おからなどすぐ腐るので肥料や鰐料
にもならず、廃棄される場合が多い。Conventionally, there is no suitable method for producing sludge, so sludge is often dried in the sun or thrown away as is, while okara, which rots quickly and cannot be used as fertilizer or crocodile food, is often discarded.
３発明が解決しようとする課題〕
上記の如き含水体を外部から加熱して乾燥しようとして
も長い時間かかり効率が悪い。従って内部から粉砕して
短時間に効率よく乾燥出来れば良い。3. Problems to be Solved by the Invention] Even if it is attempted to dry the water-containing body as described above by heating it from the outside, it takes a long time and is inefficient. Therefore, it would be better if it could be crushed from the inside and dried efficiently in a short time.
〔課題を解決するための手段フ
そこでこの含水体を密閉容器中で混練し乍ら１００℃以
上に加熱して高圧を発生さけた後、これを容器外に急激
に放出減圧すると内部の水分か爆発的に気化、含水体を
粉々に粉砕して乾燥する。[Means to solve the problem] Then, after kneading this water-containing material in a closed container and heating it to over 100°C to avoid generating high pressure, it is rapidly released outside the container and depressurized, causing the moisture inside to melt. Explosively vaporizes, pulverizes the water-containing body into powder, and dries it.

イブの外側から電熱その他で加熱すれば、内部の温間は
短時間に１２０〜１３０°Ｃにも上かり、末端のノズル
から次々に霧状に粉砕され乍ら飛散し、やがて落下して
粉体の乾燥しｆ二山が出来る。While the water-containing body is sent out through a screw through a thin pipe, if it is heated from the outside of the vibrator with electric heat or other means, the temperature inside will rise to 120-130°C in a short time, and the water will be released one after another from the nozzle at the end. The powder is crushed into a mist and scattered, and eventually falls and dries to form two mountains.
ポリエチレン樹脂の押出成型機を準用して豆腐のかすの
おからの乾燥について説明する。The drying of okara from tofu scraps will be explained using a polyethylene resin extrusion molding machine.

リュー （３）で、金属筒（４）の中を図の右方向へ移
動されろ。The okara (2) introduced through the immersion opening (+) in the figure is moved to the right in the figure through the metal tube (4) using the screw (3).
途中おから （２）は、電熱ヒーター （５）によって
１００℃以上に加熱されるか、密閉状態のためおから
（２）の中の水分（６）は気化することか出来ない。On the way, the okara (2) is heated to over 100℃ by the electric heater (5), or the okara is sealed.
The water (6) in (2) can only be vaporized.
加熱か進むにつれて、おから （２）は益々高圧となり
、右端のノズル（７）に至る。As the heating progresses, the pressure of the okara (2) becomes higher and higher until it reaches the nozzle (7) at the right end.
ノズル（７）から押出されて、常圧に開放された瞬間、
おから （２）の中の水分（６）は爆発的に気化し、お
から （２）は内部から粉々に粉砕される。The moment it is extruded from the nozzle (7) and released to normal pressure,
The water (6) in the okara (2) evaporates explosively, and the okara (2) is pulverized from inside.
水分（６）の抜は几おからの粉末（８）は、やがて降下
し、床上に粉末の山（９）を作る。After removing the moisture (6), the okara powder (8) will eventually fall and form a powder mountain (9) on the floor.
投入口から調味料や防腐斉工などを所要量混入しておか
らを間質することが出来る。The required amount of seasonings, preservatives, etc. can be mixed in through the input port to make okara grains.
ヘドロや下水汚泥の加熱に電熱ヒーターでは、 ４ラン
ニングコストが高くつくので、ボイラーの廃熱や都市ご
み焼却の廃熱などの利用によって安価に乾燥が可能であ
る。Electric heaters for heating sludge and sewage sludge have high running costs, so drying can be done inexpensively by using waste heat from boilers or waste heat from municipal waste incineration.

ズルに検討を加えれば、はとんどそのまま、準用出来る
。The equipment can be used as is with conventional polyethylene resin extrusion molding machines, provided that consideration is given to the pressure resistance and nozzle.

当期間の保存が可能となり、食用、糾料、肥料として有
効にｅＪ用が出来る。With this explosion dryer, the moisture content is 80-90% or 3-5%.
Since it can be dried, okara can be stored as is for a considerable period of time, and can be effectively used as food, starch, and fertilizer.
本発明では、耐熱性が許せば、反応終了時の染料や医薬
品の如き、粘稠な含水体でも短時間大量に処理が可能で
ある。In the present invention, if heat resistance permits, even viscous water-containing substances such as dyes and pharmaceuticals at the end of the reaction can be treated in large quantities in a short period of time.
