【発明が属する技術分野】
本発明は、機体内に設けた穀粒の貯留部に張り込んだ穀粒を、穀粒の循環装置の作動により、貯留部の下方に配位して機体内に設けた乾燥部を経て貯留部に戻すよう循環流動させ、その乾燥部において、機体に設けた熱風生成装置により生成した熱風を浴びせることで、穀粒の乾燥を行う穀粒乾燥機についての改良に関する。
【０００２】
【従来の技術】
上述の形態の穀粒乾燥機Ａは、通常、図１および図２に示している如く、上下に高い箱状乃至塔状に形成した機体１の内腔の上半側に、乾燥しようとする穀粒を張り込み貯留する貯留部ａを形成し、機体１内の下半側には、熱風を誘導する通気性の隔壁よりなる風洞状の導風路１０と前記貯留部ａから順次流下してくる穀粒を流過させる通気性の隔壁よりなる穀粒の流下路１１と前記導風路１０から吹き出されて穀粒の流下路１１を吹き抜けた熱風を排風として誘導する排風路１２とが、通気性の隔壁１３…を介して隔てられた状態で並列する乾燥部ｂを設け、機体１の前面側には、前記乾燥部ｂの導風路１０に送り込む熱風を生成するバーナー装置２０よりなる熱風生成装置２を装設し、機体１の後面側には、前記乾燥部ｂの排風路１２から排風を引き出す吸引用送風機３を装設し、機体１の外面および機体１内の上部および底部に、穀粒の張り込みと、張り込んだ穀粒を循環させるための昇降機４０・上部コンベア４１・下部コンベア４２・回転シャッター４３等よりなる穀粒の移送装置４を設けることで構成している。
【０００３】
【発明が解決しようとする課題】
上述の形態の穀粒乾燥機は、機体１内の貯留部ａに張り込んだ穀粒を循環させて、その穀粒が乾燥部ｂの穀粒の流下路１１を流過する間に、灯油を燃焼させるバーナー装置２０からなる熱風生成装置２で生成した熱風を浴びせて、乾燥させることから、穀粒が所定の水分値に乾燥するまでの乾燥行程中、穀粒の乾燥に適応する温度と量の熱風を、継続して送給し得るようにするため、バーナー装置２０に燃料の灯油を送給して燃焼作動を行わせることになるので、多量の燃料を要し、燃料費が嵩む問題がある。また、穀粒を乾燥させるための熱風を、燃料灯油の燃焼により生成することから、その灯油の燃焼の際に生ずるＣＯ_２ガスを多量に発生させる問題がある。
【０００４】
本発明は、従前の穀粒乾燥機に生じている上述の問題に対処するためになされたものであって、穀粒を乾燥させるための熱風の生成が、バーナー装置における燃料灯油の燃焼量を少なく抑えて行えるようにして、燃料灯油の消費量の低減とＣＯ_２ガスの発生量の削減とが得られるようにする新たな手段を提供することを目的とする。
【０００５】
【課題を解決するための手段】
そして、本発明においては、上述の目的を達成するための手段として、機体１内の上部側に、穀粒の貯留部ａを設け、機体１内の下部側に、熱風を誘導する導風路１０と、貯留部ａから順次流下してくる穀粒を流過させる穀粒の流下路１１と、導風路１０から吹き出されて穀粒の流下路１１を吹き抜けた熱風を排風として誘導する排風路１２とが、それぞれ通気性の隔壁１３で仕切られて並列する乾燥部ｂを装設し、その乾燥部ｂの導風路１０の熱風の取入口１０ａを、機体１の前壁１ａに開設し、機体１の外面の前面側には、前記熱風の取入口１０ａに連通するダクト５を設け、そのダクト５の前面側に、灯油を燃料として燃焼させるバーナー装置２０を、ハウジング２１により覆い込んで配設し、そのハウジング２１の前面側に前記バーナー装置２０の外気の取入口２３を開設し、ハウジング２１の後面側にバーナー装置２０で生成した熱風の吐出口２２を開設して前記ダクト５に連通させ、機体１の後面側に、前記排風路１２から排風を引き出す吸引用送風機３とを装架して、機体１内の貯留部ａに張り込む穀粒を熱風の送給により乾燥させる穀粒乾燥機において、乾燥部ｂの排風路１２内に、銅材またはアルミ材等の熱伝率の高い材質のものからなるパイプ７を、それの内腔が排風路１２内の排風から遮断された状態として配設し、そのパイプ７の後端側を、機体１後面側に突出させて、後端開口７０を機体１の外部の大気に開放し、そのパイプ７の前端側の開口７１を、導風路１０の熱風の取入口１０ａとバーナー装置２０を覆うハウジング２１に設けた熱風の吐出口２２との間に配設せるダクト５内に連通させ、吸引用送風機３の吸引圧によりパイプ７を介して吸引される外気を、排風路１２内の排風の余熱により昇温させて、熱風生成装置２で生成した熱風に合流させて導風路１０に送り込むようにしたことを特徴とする穀粒乾燥機提起するものである。
