【0001】
【発明の目的】
この発明は、湿潤粉粒物を乾燥粉末物化する粉粒物の乾燥技術に関するものであって、特に、高い栄養価と豊富な食物繊維をもちながら、その大部分がこれまで産業廃棄物として処理せざるを得なかった、豆腐のオカラや落花生のカラ等の水分を多量に含む粉粒物を、効率的に乾燥し、粉末化して長期保存可能な新たな食品素材として提供できるようにする新規な構造からなる湿潤粉粒物用乾燥装置を提供しようとするものである。
【0002】
【従来の技術】
豆類は、穀類や芋類に並ぶ主要な食料であり、主食に準ずる食品としての永い歴史をもち、我が国においても種々の伝統的な食品の生産に利用され、特に大豆は、製油工業をはじめとし、黄粉、豆腐、油揚げ、湯葉、豆乳、納豆、味噌、醤油、もやし等、極めて多様な食品への利用がなされているが、その中でも豆腐、油揚げ、湯葉および豆乳等の生産に際して副産物として生じるオカラは、植物性蛋白質、脂質、粗繊維、灰分等の栄養素を豊富に含む良質の食品であり、この中の食物繊維は、西洋化した肉を中心とした食生活が要因の一つとされる大腸癌の予防や、動物性脂肪の取り過ぎ、ストレスおよび運動不足が原因と言われる高コレステロール症、動脈硬化、便秘や糖尿病等の予防および改善、更に近年、大きな社会問題として取り上げられるようになったダイオキシン等の有害物質の体外への排出作用等、現代生活において健康を維持する上で欠くことのできない大切な要素の一つとして知られている。
【0003】
ところが、このような人々の健康維持に極めて有用な成分を含むオカラも、その食品としての利用範囲は極めて少なく、昔から「卯の花」等一部の総菜として食されるに留まっており、それも食生活の西洋化によって益々食卓に上る機会が少なくなってきていることから、健康食品としての豆腐が見直されて消費を拡大していくに連れ、このオカラだけが以前にも増して大量に産業廃棄物化してしまい、飼料や肥料等への利用に回されるもの以外の大部分のものを、経費を使ってそのまま廃棄処分しているというのが現状であり、豆類を扱う食品業界を大いに悩ませるばかりでなく、食資源のリサイクルという視点からもオカラの有効利用が大きな課題となっている。
【0004】
豆腐の製造等の圧搾工程にともなって生ずるオカラは、大豆の皮や細胞壁等の不溶性部、および搾りきれなかった豆乳が残され、水分を多量に含む状態のまま発生し、高い栄養価をもつために微生物の増殖も早く、比較的短時間の中に腐敗してしまうという欠点をもち、しかも、これまでの技術では乾燥も困難なことから長期保存ができない上、低温貯蔵するにしても嵩張ってしまって効率も悪く、したがって、そのままで他の食品原料とするには不向きな資材と見放され、また、容易に腐敗してしまう性質は、家畜用飼料としても取り扱い難く、肥料としての利用に際しても、窒素成分を多く含むため、堆肥化する際に、アンモニア揮散による強い悪臭が発生し、周囲の環境汚染が懸念され、密閉型発酵槽の使用や脱臭装置の設置等が不可欠であり、大きな設備投資を必要とするため、広く普及していないのが現状である。
【0005】
この発明は、以上のような事情に鑑み、水分を多量に含むオカラを、食品として長期保存可能な程度に乾燥させ、これを食物繊維食品として広く利用することはできないものかとの判断から、逸速くその開発、研究に着手し、長期に渡る試行錯誤と幾多の試作、実験とを繰り返してきた結果、今回、遂にオカラや落花生のカラ等を含む湿潤粉粒物を乾燥して粉末化することができるようにする新規な構造からなる湿潤粉粒物用乾燥装置を実現化することに成功したものであり、以下では、図面に示すこの発明を代表する実施例と共に、その構成を詳述することとする。
【0006】
【発明の構成】
図面に示すこの発明を代表する実施例からも明確に理解されるように、この発明に包含される湿潤粉粒物用乾燥装置は、基本的に次のような構成から成り立っている。
即ち、軸心傾斜角度を1/(40ないし60)勾配前後とし、回転自在に支持した円筒体形状の分割傾斜ドラムを、相互の傾斜方向が合致しないジグザグ状配置となるようにして上下に複数個組み合わせた上、最上位の分割傾斜ドラムの傾斜上手側開口および最下位の分割傾斜ドラムの傾斜下手側開口を除く各分割傾斜ドラム開口を通気性堰止め板で施蓋状となるようにすると共に、上下に隣接する開口同士は、当該通気性堰止め板に併設した粉粒物流下用の中間ホッパーを介して連通状となるようにし、最上位から最下位までの全ての分割傾斜ドラムが、実質的に順次上から下に連通するようにした上、各分割傾斜ドラム内には、夫々傾斜上手側から下手側に向けて熱風を送風可能にする一方、各分割傾斜ドラム外周面適所に歯車環を装着した上、複数個単位の分割傾斜ドラムの歯車環に一本の無端状ギアベルトが噛合するようにするか、もしくは各分割傾斜ドラム毎に個別の無端状ギアベルトが夫々噛合するようにして張設され、それら無端状ギアベルトに伝達機構部を介して回転駆動源を接続してなる構成を要旨とする湿潤粉粒物用乾燥装置である。
【0007】
この基本的な構成からなる湿潤粉粒物用乾燥装置を、より具体的な構成のものとして示すと、軸心傾斜角度を1/(40ないし60)勾配前後とし、回転自在に支持した円筒体形状であって、その内壁面には、軸心に平行状、且つ周方向に略等間隔を隔てた配置で複数条のブレードを突設けてなる分割傾斜ドラムを、相互の傾斜方向が合致しないジグザグ状配置となるようにして上下に複数個組み合わせた上、最上位の分割傾斜ドラムの傾斜上手側開口および最下位の分割傾斜ドラムの傾斜下手側開口を除く各分割傾斜ドラム開口を通気性堰止め板で施蓋状となるようにすると共に、上下に隣接する開口同士は、当該通気性堰止め板に併設した粉粒物流下用の中間ホッパーを介して連通状となるようにし、最上位から最下位までの全ての分割傾斜ドラムが、実質的に順次上から下に連通するようにした上、各分割傾斜ドラム内には、夫々傾斜上手側から下手側に向けて熱風を送風可能にする一方、各分割傾斜ドラム外周面適所に歯車環を装着した上、複数個単位の分割傾斜ドラムの歯車環に一本の無端状ギアベルトが噛合するようにするか、もしくは各分割傾斜ドラム毎に個別の無端状ギアベルトが夫々噛合するようにして張設され、それら無端状ギアベルトに、減速機構、出力用プーリー、出力用ギア等からなる伝達機構部を介して回転駆動源を接続し、駆動力を各分割傾斜ドラムに伝達するようにした構成を要旨とする湿潤粉粒物用乾燥装置であるということができる。
【0008】
この発明の湿潤粉粒物用乾燥装置を、更に具体的な構成で示すならば、軸心傾斜角度を1/50勾配前後とし、回転自在に支持した全長1500mm前後、内径600mm前後の円筒形状体であって、内径壁面には軸心に平行状、且つ周方向に略等間隔を隔てて配置する複数条のブレードを設けてなる分割傾斜ドラムを、相互の傾斜方向が合致しないジグザグ状配置となるようにして上下に2または3個組み合わせた上、最上位の分割傾斜ドラムの傾斜上手側開口および最下位の分割傾斜ドラムの傾斜下手側開口を除く各分割傾斜ドラム開口を通気性堰止め板で施蓋状となるようにすると共に、上下に隣接する開口同士は、当該通気性堰止め板に併設した粉粒物流下用の中間ホッパーを介して連通状となるようにし、分割傾斜ドラムが上下2個の組合せでは略コの字状流下経路、同3個のときは略Z字状流下経路を形成して最上位から最下位までの全ての分割傾斜ドラムが、実質的に順次上から下に連通すると共に、最上位の分割傾斜ドラムの傾斜上手側開口には投入用ホッパーを、また最下位の分割傾斜ドラムの傾斜下手側開口には回収容器を夫々併設するようにした上、各分割傾斜ドラム内には、夫々傾斜上手側から下手側に向け、約500℃以下の熱風を送風可能にする一方、各分割傾斜ドラム外周面適所に歯車環を装着した上、複数個単位の分割傾斜ドラムの歯車環に一本の無端状ギアベルトが噛合するようにするか、もしくは各分割傾斜ドラム毎に個別の無端状ギアベルトが夫々噛合するようにして張設され、それら無端状ギアベルトに、減速機構、出力用プーリー、出力用ギア等からなる伝達機構部を介して回転駆動源を接続し、駆動力を各分割傾斜ドラムに伝達するよう構成した湿潤粉粒物用乾燥装置となる。
【0009】
更に、表現を変えて示せば、軸心傾斜角度を1/50勾配前後とし、回転自在に支持した円筒体形状であって、その内壁面には、軸心に平行状、且つ周方向に略等間隔を隔てた配置で複数条のブレードを突設けてなる分割傾斜ドラムを、相互の傾斜方向が合致しないジグザグ状配置となるようにして上下に複数個組み合わせた上、最上位の分割傾斜ドラムの傾斜上手側開口および最下位の分割傾斜ドラムの傾斜下手側開口を除く各分割傾斜ドラム開口を通気性堰止め板で施蓋状となるようにすると共に、上下に隣接する開口同士は、当該通気性堰止め板に併設した粉粒物流下用の中間ホッパーを介して連通状となるようにし、最上位から最下位までの全ての分割傾斜ドラムが、実質的に順次上から下に連通するようにした上、各分割傾斜ドラム内には、夫々傾斜上手側から下手側に向けて熱風を送風可能にする一方、各分割傾斜ドラムは、夫々の適所外周面に環状の歯車環が同心状に装着され、各分割傾斜ドラム毎に、内向きもしくは外向きの噛合歯を有する個別の無端状ギアベルトの所定範囲が夫々噛合するよう張設されると共に、各無端状ギアベルト中間位置の夫々に、減速機構、出力用プーリー、出力用ギア等からなる伝達機構部を介して回転駆動源を接続し、駆動力を各分割傾斜ドラムに伝達するようにした構成を要旨としてなる湿潤粉粒物用乾燥装置ということができる。
【0010】
また、この発明には、軸心傾斜角度を1/50勾配前後とし、回転自在に支持した円筒体形状であって、その内壁面には、軸心に平行状、且つ周方向に略等間隔を隔てた配置で複数条のブレードを突設けてなる分割傾斜ドラムを、相互の傾斜方向が合致しないジグザグ状配置となるようにして上下に複数個組み合わせたものを1ユニットとし、それを左右に2または3連とした上、各ユニット毎の最上位の分割傾斜ドラムの傾斜上手側開口および最下位の分割傾斜ドラムの傾斜下手側開口を除く各分割傾斜ドラム開口を通気性堰止め板で施蓋状となるようにすると共に、上下に隣接する開口同士は、当該通気性堰止め板に併設した粉粒物流下用の中間ホッパーを介して連通状となるようにし、少なくとも各ユニット毎の最上位から最下位までの全ての分割傾斜ドラムが、実質的に順次上から下に連通すると共に、各ユニット毎の最上位の分割傾斜ドラムの傾斜上手側開口には投入用ホッパーを、また同最下位の分割傾斜ドラムの傾斜下手側開口には回収容器を夫々併設するようにした上、各分割傾斜ドラム内には、夫々傾斜上手側から下手側に向け、約500℃以下の熱風を送風可能にする一方、全ての分割傾斜ドラムは、夫々の適所外周面に環状の歯車環が同心状に装着された上、上下方向で同位にある各ユニットの分割傾斜ドラムの全ての歯車環毎に、夫々一本の無端状ギアベルトの対応する箇所の所定範囲が噛合するよう張設されると共に、各無端状ギアベルト中間位置の夫々に、減速機構、出力用プーリー、出力用ギア等からなる伝達機構部を介して回転駆動源を接続し、駆動力を各分割傾斜ドラムに伝達するようにした構成を要旨とする湿潤粉粒物用乾燥装置を包含している。
【0011】
分割傾斜ドラムは、湿潤粉粒物に回転、落下という動きを発生させ、熱風への接触が満遍なく促進されるようにする機能を果たすと共に、熱風を湿潤粉粒物の移動方向に沿って導く機能を果たすものであり、熱風を通過しない金属板、熱風の一部を通過するようパンチング加工を施した金属板、あるいは金属ワイヤーを網状に組み合わせてメッシュ状としたもの等を筒状に形成し、湿潤粉粒物を肉厚方向に通過しないよう構成し、外周壁面の適所に無端状ギアベルトの所定範囲を噛合可能な歯車環を装着したものとしなければならず、筒状断面形は、円形、楕円形、あるいは多角形等、軸心回り周方向に回転して収容した湿潤粉粒物を攪拌、移動可能に形成したものとすべきであり、最上位段側の分割傾斜ドラムの周壁面は、熱風を通過し易いメッシュ状とし、最下位段側の分割傾斜ドラムを金属板からなる密閉状のものとするように、ドラム形成素材や構造、形状等を適宜変更、組み合わせたものとすることもできる。
【0012】
そして、筒形状の中心部に軸芯部を設け、該軸芯部から放射状に延出された複数本の支柱部を円筒状部内周壁面に結合、一体化し、該軸芯の両端部を軸受けによって回転自在に軸支するものとすることができる外、一端側だけ軸着構造を設けるか、筒形状の一端側の外周壁面に複数の転動ローラーを当接して回転自在に支持し、該筒形状の他端側を、回転駆動用の無端状ギアベルトで支持する構造とし、該無端状ギアベルト上に載置状に支持されものとし、各分割傾斜ドラムの自重により、夫々対応する無端状ギアベルト上に自らの歯車環を押し当て、無端状ギアベルトの張りの弛緩に対して常に追随し、噛合状態を維持することができるようにしたものとする。
【0013】
ブレードは、分割傾斜ドラムの回転に伴って湿潤粉粒物を、分割傾斜ドラム内壁面に留まったままで回転方向の上方に誘導し、それら湿潤粉粒物が分割傾斜ドラム内上方から下方に向けて落下、飛散するよう機能するものであり、分割傾斜ドラムの筒形状内周壁面から中心側に向かって突出したものとするか、あるいは、回転の軸芯部から放射状に突出するものとして設けるべきであり、その形状は、翼形、鈎形、爪形、棒形状等のものとすることが可能であり、形状や大きさが同じもの、あるいは形状や大きさが異なるものを、均等または不均等に点在するよう突設したものや、軸芯部に沿って平行状となるような細長い板状のものを周方向に等間隔、あるいは不当間隔となるように設けたものとすることができる。更に、突条に形成した複数条のブレードの中、一部または全部の、分割傾斜ドラム上位端部に位置するブレード端を回転方向に向けて湾曲するか、または舌片状あるいは棒状に形成し、点在状に立設した複数のブレードを、湾曲状に配置し、投入される湿潤粉粒物を分割傾斜ドラム内へ導くよう形成するのが望ましい。
【0014】
歯車環は、円筒体形状の軸心回りに回転自在に支持された分割傾斜ドラムに対して無端状ギアベルトからの回転駆動力を伝達する機能を果たすものであり、歯丈や歯幅、ピッチ等が適正に設定された上、無端状ギアベルトに確実に噛合するものとし、しかも、分割傾斜ドラムの外周壁面に一体的に設けられたものとしなければならず、鋳造、鍛造、機械加工等を施して分割傾斜ドラムの外周に一体的に歯車を形成してしまうようにすることができる外、環状に別体形成した歯車を溶接、鑞付け、あるいはボルト結合等として後付けした構造とすることが可能である。そして、この歯車環を構成する歯車は、当然のことながら分割傾斜ドラムを回転駆動するに充分な強度を有するものとしなければならず、また、無端状ギアベルトが分割傾斜ドラムの一部荷重を受けて支持するよう構成する場合には、分割傾斜ドラムの荷重を上乗せした駆動力を充分に伝達可能な程度の強度に設定され、分割傾斜ドラムの円筒体軸心とピッチ円の中心とが略一致するように構成したものとしなければならず、必要に応じ、歯幅方向の両端に無端状ギアベルトが外れぬよう案内、保持する案内鍔を夫々突出、形成したものとすることができる。
【0015】
通気性堰止め板は、上側に配置された分割傾斜ドラムの下側開口から放出される粉粒物を通過させず、外部に露出させることなく堰止める状態とし、中間ホッパー側へ向けて落下するように導き、熱風の一部を通過可能とし、外部に放出する機能を果たすものであって、分割傾斜ドラム内に流入した熱風を適度に減圧すると共に、粉粒物から放出された蒸気や湯気等の湿気を、速やかに外側に放出可能な構造としなければならず、パンチングメタルやメッシュ部材等から形成するか、それらを組み合せたものから形成することが可能である外、通気性を有する発泡ウレタン、厚紙あるいは繊維素材等を単独あるいは複数層に重ね合わせ、フィルター状に形成したもの等とすることも可能であって、乾燥後の粉粒物が通過しない100〜300μm程度の間隙を有するものとする。
【0016】
中間ホッパーは、上下に隣接する分割傾斜ドラムの開口同士を連通状とし、上側の分割傾斜ドラムから放出されて来る粉粒物を、下側の分割傾斜ドラム側へ導く機能を果たすものであり、落下する粉粒物の略全量を下側分割傾斜ドラム内に供給するよう形成しなければならず、上下の分割傾斜ドラムに夫々設けられた通気性堰止め板に一体的に連続する構造とするのが望ましく、通気性堰止め板と同様に通気性を有する構造とすることができる外、通気性を有さず、流入してくる粉粒物および熱風をそのまま案内、通過させるように形成したものとすることができる。
【0017】
無端状ギアベルトは、回転駆動源から出力された駆動力を、分割傾斜ドラムに装着された歯車環に対し、回転力として伝達する機能を果たすものであり、歯車環の歯丈や歯幅、ピッチ等に適合する歯形に設定され、歯車環の所定範囲に渡り、確実に噛合する構造としなければならず、減速機、出力用プーリー、出力用ギア等の伝達機構部を介して、回転駆動源からの出力を受けることができ、分割傾斜ドラムを確実に回転駆動できる程度の充分な強度を有するものとすべきであって、少なくとも歯形部分が、噛合の際の静粛性を確保可能な天然樹脂または合成樹脂からなり、ベルト内に無端状の補強ワイヤーや、無端帯状の金属板等を一体成型し、充分に補強されたものを用いるのが望ましい。
【0018】
伝達機構部は、回転駆動源からの出力を、無端状ギアベルトに対して、回転力として伝達し、その結果として分割傾斜ドラムをその軸心回りに回転駆動する機能を果たすものであり、無端状ギアベルトを巻き掛けた出力用プーリーを回転駆動源の回転軸に装着したものや、回転駆動源の回転軸に出力用ギアを取着し、該出力ギアに噛合して軸回りの角速度を減少させるギア式の減速機を設け、該減速機の出力軸に、無端状ギアベルトを巻き掛けた出力用プーリーを装着してなる構造のものとしたり、回転駆動源の出力軸には小径のプーリーを、また無端状ギアベルトを巻き掛けた出力用プーリーの回転軸には大径のプーリーを夫々装着し、それら二軸間にベルトを巻き掛けることによって減速機構を形成したものとすることができる。
【0019】
回転駆動源は、前記した分割傾斜ドラムを、その円筒形の軸心回りに所定の一定速度で回転駆動する機能を果たすものであり、騒音が少なく、排気が無い上、要求される軸出力を容易に発揮させることができるといった条件に適う直流または交流電源によって駆動する電動モーターを用いるのが最も望ましいといえるが、場合によってはガソリンエンジンやディーゼルエンジン等といった公知の他の駆動源を利用することも勿論可能である。
【0020】
投入用ホッパーは、最上位に配置された分割傾斜ドラムの上側に位置する端部開口側から湿潤粉粒物を投入し易くする機能を果たすものであって、湿潤粉粒物が付着せず、分割傾斜ドラム内に順調に投入されるように構成したものとすべきであり、例えば駆動モーター等によって投入ホッパーを小刻みに振動させるカムを回転駆動するよう構成し、付着した湿潤粉粒物を振り落とすようにしたものとするか、あるいは、投入ホッパー本体を揺動自在に支持し、コイルバネや板バネ等の弾発材部で、姿勢維持するよう支持したものとし、湿潤粉粒物の落下に伴う衝撃力を受けて揺動するかした構成のものとし、更に、該弾発材部を投入用ホッパーに対して進退移動させ、湿潤粉粒物の水分含有量の違い等による重量変化に対応して、その弾発力を適宜調節できるように構成したもの等とすることも可能である。
【0021】
送出口は、乾燥を終えた乾燥粉末物を、最下位の分割傾斜ドラム外で所望する方向へ向けて円滑に送出する機能を果たすものであり、目詰まり等を起こさず、速やかに送出できるような形状および寸法に設定すべきであり、フィルターや所定高さの仕切り等を設け、粒子の粗いものと細かいものとに分別して送出するようにした構成を付加することができる外、送出された乾燥粉末物中に混入してしまった異物の分離や、乾燥粉末物の計量および製品包装等を自動的に行うことのできるようにした、補助的に有利に作用する各種装置を併設することも必要に応じて適宜採用可能である。
【0022】
回収容器は、乾燥工程を経て分割傾斜ドラム外へ送出されてくる乾燥粉末物を、周辺に飛散させたりすることなく所定量毎一まとめに回収する機能を果たすものであって、送出口から送り出されてくる乾燥粉末物を漏れなく回収できる容器状のもので、満杯時の交換がし易く、しかも可搬、移動にも都合が良いように工夫したものに形成すべきであり、上記した如く、送出口に、粒子の粗いものと細かいものとを分別する機能を併設したものの場合には、夫々の送出先に個別の回収容器を並置するようにするか、または同一の回収容器内に仕切りを設け、粉末物の粗いものと細かいものとが混合しないようにした回収ができるようにしたり、また、送出口に、乾燥粉末物の計量および製品包装等を自動的に行う計量、包装機構が組み込まれたものの場合には、回収容器の替わりに、ベルトコンベア等の搬送装置を配し、個別に所定量毎に包装された乾燥粉末物を、所望する箇所まで自動的に移送できるよう構成したものとすると極めて好都合のものとなる。
【0023】
熱風は、湿潤粉粒物を焦がしてしまうことなく乾燥、攪拌する機能を果たすものであり、バーナーから送出される熱風や、ボイラーから放出される加熱蒸気、加熱ヒーターと送風機とを組み合わせてなる温風機からの熱風等、公知の各種熱源によるものの利用を可能とするが、長時間に渡って安定した熱量の送風を可能にすると共に、安全性にも十分配慮されたものを採用すべきであり、また、各ドラムや中間ホッパー部内適所には温度センサーを設ける等して、摂氏500℃以下の最適温度に自動制御できるよう構成してなるものとするのが望ましく、更には、乾燥後の乾燥粉末物を食品として利用する装置の場合は、変色や衛生面、栄養価値等に支障を来すことのない熱風の供給ができるものとし、食味その他商品価値に悪影響のないものとする必要がある。
【0024】
ユニットは、湿潤粉粒物の乾燥工程に必要とする熱風を受けての移動長を確保するために組み合わせる複数個を一まとめとした分割傾斜ドラム群であり、投入用ホッパーから送出口までの経路を湿潤粉粒物が停滞することなく移動可能となるよう、隣接する分割傾斜ドラム相互は、その傾斜方向が合致しないジグザグ状配置にした上下(斜め方向にずらした上下も含む。)に立体的に組み合わせて設置場所の効率化を図るための単位として機能するものであり、1ユニット毎に湿潤粉粒物を投入し、該ユニット内の各分割傾斜ドラムには傾斜下方側に向けて熱風が送り込まれ、また各分割傾斜ドラムとも回転駆動するようにし、当該ユニット内の全ての分割傾斜ドラムを経由する過程で湿潤粉粒物が所定の乾燥度にまで乾燥されることになる。
【0025】
なお、当然のことながら、ユニット毎、その最上位の分割傾斜ドラムの上側開口には投入用ホッパーが、また最下位の分割傾斜ドラムの下側開口には回収容器が夫々配設されてなるものとすべきであり、個々の分割傾斜ドラムに対して無端状ギアベルト、伝達機構部および回転駆動源を夫々設けたものとすることができる外、1ユニット中の複数個の分割傾斜ドラム、または、1ユニット中の全ての分割傾斜ドラムを同時に駆動可能とするよう無端状ギアベルトを配設し、該無端状ギアベルトを伝達機構部および回転駆動源で駆動できるよう構成したものとすることも可能であり、処分する湿潤粉粒物の量に応じ、このように形成したユニットを、左右方向に2または3連程度、隣接させるようにして一個のフレーム内に配置させ、それをこの発明の湿潤粉粒物用乾燥装置とすることができる。
【0026】
張力調節機構は、無端状ギアベルトの分割傾斜ドラム歯車環への噛合状態を最適な状態に調節可能とする機能を果たすものであり、歯形部分を内周面に形成した無端状ギアベルトを、分割傾斜ドラム歯車環と、回転駆動源の伝達機構部の出力ギアとの間に巻き掛けた構造であれば、該伝達機構部もしくは分割傾斜ドラム歯車環の回転軸心間距離を適宜変更して調節可能とするか、あるいは、伝達機構部と分割傾斜ドラム歯車環との間に位置する無端状ギアベルトの中途部を、該伝達機構部および分割傾斜ドラム歯車環の回転軸心に対して同一平面状で三角形を形成する如く、調節用ギアを外側に向けて進退移動および仮固定自在に軸着し、該調節用ギアを適宜移動させ、無端状ギアベルトの張り具合を調節可能とするようにする外、後述する実施例にも示すように、歯形部分を外周面に形成した無端状ギアベルトを、回転駆動源の伝達機構部の出力用プーリーと調節用プーリーとの間に張設し、該無端状ギアベルトの所定範囲を、分割傾斜ドラム歯車環に当接状とした構造の場合には、該回転駆動源の伝達機構部の出力用プーリー、または調節用プーリーの何れか一方を適宜移動および仮固定可能になるように構成するか、あるいは、分割傾斜ドラム歯車環の所定範囲に噛合する無端状ギアベルトの背面側適所に、一個または複数個の張力調節用プーリーを、該分割傾斜ドラム歯車環の中心に向けて進退移動および仮固定可能とするよう配置させ、該張力調節用プーリーを進退移動張設し、無端状ギアベルトの分割傾斜ドラム歯車環への噛合状態を最適に調節できるよう構成することができる。
以下では、図面に示すこの発明を代表する実施例と共に、その構造について詳述することとする。
【0027】
【実施例1】
図1の湿潤粉粒物用乾燥装置の縦断面図、および図2の湿潤粉粒物用乾燥装置の分割傾斜ドラムと駆動機構とを示す断面図に示される事例は、上下2段に配された分割傾斜ドラムの夫々に無端状ギアベルトおよび回転駆動源を設けたもので、基本的構成からなるこの発明に包含される湿潤粉粒物用乾燥装置の代表的な実施例を示すものである。
当該湿潤粉粒物用乾燥装置1は、矩形枠状に形成された金属製骨格枠11の上下に、夫々上段の分割傾斜ドラム2および下段の分割傾斜ドラム3の夫々が、上段の分割傾斜ドラム2の傾斜下手側開口と、下段の分割傾斜ドラム3の傾斜上手側開口とを近接させ、上下方向にジグザグ状配置となるようにして組み合わせられている。
【0028】

OBJECT OF THE INVENTION
TECHNICAL FIELD The present invention relates to a technique for drying a granular material that turns a wet granular material into a dry powder. In particular, the present invention has a high nutritional value and abundant dietary fiber, most of which has been treated as industrial waste. New products that can be provided as new food materials that can be efficiently dried, powdered, and stored for a long period of time, such as tofu okara and peanuts. It is an object of the present invention to provide a drying apparatus for wet powder granules having a simple structure.
[0002]
[Prior art]
Beans are the main foods alongside cereals and potatoes, and have a long history as foods similar to staple foods. They are also used in the production of various traditional foods in Japan. , Yellow powder, tofu, fried tofu, yuba, soy milk, natto, miso, soy sauce, bean sprouts, etc. Is a high-quality food that contains abundant nutrients such as vegetable protein, lipids, crude fibers, and ash. Prevention and improvement of cancer, hypercholesterolosis, arteriosclerosis, constipation and diabetes, which are said to be caused by excessive intake of animal fat, stress and lack of exercise. Such as discharge action from the body of harmful substances such as dioxin, which came to be under, is known as one of the important elements that can not be lacking in maintaining health in modern life.
[0003]
However, Okara, which contains ingredients that are extremely useful for maintaining the health of these people, has a very limited range of use as a food, and has long been eaten as a part of side dishes such as “bamboo flowers”. With the westernization of eating habits, there are fewer opportunities to go up to the table, so as Tofu as a health food is reviewed and consumption is expanding, only this Okara is a larger industry than before The current situation is that most items other than those that have been turned into waste and used for feed or fertilizer are disposed of as they are, using expenses. Not only is it bothering, but the effective use of Okara has become a major issue from the perspective of food resource recycling.
[0004]
Okara produced in the pressing process such as tofu production is produced with a high nutritional value, leaving insoluble parts such as soybean skin and cell walls, and soy milk that could not be squeezed out, and containing a large amount of water. As a result, microorganisms grow quickly and decay in a relatively short period of time. Moreover, they cannot be stored for a long time because they are difficult to dry with conventional techniques, and they are bulky even when stored at low temperatures. Therefore, it is not suitable for use as a raw material for other foods as it is, and the property of being easily spoiled is difficult to handle as livestock feed. When using it, it contains a lot of nitrogen components, so when composting, a strong bad odor due to ammonia volatilization occurs, and there is a concern about environmental pollution in the surroundings, so it is impossible to use a closed fermenter or install a deodorization device , And the order that requires a large capital investment, which has not yet been widely used.
