Description

本発明は、循環流下する穀物に遠赤外線を均等に放射して穀物を乾燥する、遠赤外線穀物乾燥装置に関する。   The present invention relates to a far-infrared grain drying apparatus that uniformly radiates far-infrared rays to circulated grains and dries the grains.

従来、前後方向に長い角筒状の乾燥機本体内の集穀部の両側の一方を熱風送風室、そしてもう一方を排塵風室とし、乾燥機の短辺となる左右方向に、熱風送風室に通ずる複数の熱風室と排塵風室に通ずる複数の排風室とを両室間に巾狭の乾燥通路を形成されるよう交互に架設してそれぞれを熱風室、乾燥通路、排風室として配置し、乾燥部の直下に乾燥機の長辺となる前後方向に複数配置した山形仕切壁により形成された複数列の交差流下繰出し室の下部に前後方向に回転自在に軸架した繰出しロールによって穀物を定量的に繰出し、繰出しロールの周囲を熱風送風室、排塵風室および繰出し室で囲まれた構成となった穀物乾燥機は特開昭61−55037号公報のように公知となっている。   Conventionally, a hot air blower chamber is used in one side of the cereal collecting part in a rectangular tube-shaped dryer body that is long in the front-rear direction, and the other is a dust blower chamber. A plurality of hot air chambers that communicate with the chamber and a plurality of exhaust air chambers that communicate with the dust exhaust air chamber are alternately laid to form a narrow drying passage between the two chambers, and each of the hot air chamber, the drying passage, and the exhaust air Feeding that is arranged as a chamber, and is pivoted in the front-rear direction so as to be freely rotatable in the lower part of a plurality of rows of cross-flow feeding chambers formed by a plurality of mountain-shaped partition walls arranged in the front-rear direction, which is the long side of the dryer, immediately below the drying unit A grain dryer having a structure in which grains are fed out quantitatively by a roll and the circumference of the feed roll is surrounded by a hot air blowing chamber, a dust exhaust chamber and a feeding chamber is known as disclosed in JP-A-61-55037. It has become.

また上記の構成に、集穀部に繰出し部より散粒状態で排出される穀物に遠赤外線を放射する遠赤外線放射体を配設し、さらに遠赤外線放射体の上半分周囲を反射板で覆って、遠赤外線放射体より排出された排熱風は、吸入外気とともに熱風起成室へ吸入する構成とした遠赤外線穀物乾燥機は、特許第3043572号公報のように公知である。   In the above configuration, a far-infrared radiator that radiates far-infrared rays is disposed on the grain that is discharged from the feeding unit in the grain collecting unit, and the upper half of the far-infrared radiator is covered with a reflector. A far-infrared grain dryer having a configuration in which the exhausted hot air discharged from the far-infrared radiator is sucked into the hot-air generating chamber together with the sucked outside air is known as Japanese Patent No. 3043572.

特開昭61−055037号公報JP 61-055037 A 特許第3043572号公報Japanese Patent No. 3043572

特許文献1を実施した穀物乾燥機においては、乾燥通路を巾狭としているにも係わらずその乾燥通路の通風面積を広く確保することが出来るので、効率よくしかも均一に穀物が流下することが出来るので、穀物の均一乾燥を実現することが出来ている。また乾燥通路が巾狭であるので通風抵抗が少なく、無理なく穀物層の通風を行うことが出来るので、送風機の動力を小さくしても有効に通風できることを可能としている。   In the grain dryer which implemented patent document 1, although the drying channel | path is made narrow, since the ventilation area of the drying channel | path can be ensured widely, a grain can flow down efficiently and uniformly. Therefore, uniform drying of the grains can be realized. In addition, since the drying passage is narrow, the resistance to ventilation is low and the grain layer can be ventilated without difficulty. Therefore, it is possible to effectively ventilate even if the power of the blower is reduced.

さらに、特許文献2のように特許文献1の構成の集穀部に遠赤外線放射体を設け、繰出しロールから定量的に散粒状態で流下する穀物に遠赤外線を放射して穀物を内部から温め、穀物の水分を表面に移行させ、その後乾燥部の乾燥通路で遠赤放射体で発生した燃焼風と外気を混合させた乾燥風の通風を受けて穀物から水分を取除く乾燥方式によって、穀物の内部と表面の水分差で発生する穀物の亀裂を生じさせること無く、早く品質よく穀物を乾燥することを可能としている。   Further, as in Patent Document 2, a far-infrared radiator is provided in the cereal collection part of Patent Document 1, and far-infrared radiation is emitted from the feeding roll to the grains that flow quantitatively in a dispersed state to warm the grains from the inside. The grain is transferred to the surface by the drying method that removes the moisture from the grain by receiving the ventilation of the drying air mixed with the combustion air generated by the far-red radiator and the outside air in the drying passage of the drying part. The grain can be dried quickly and with high quality without causing cracks in the grain caused by the difference in moisture between the inside and the surface of the grain.

近年の農業改革において大規模農業が奨励され、集団化、企業化が促進される中で大型の穀物乾燥機の要望が高まってきているのが現状である。遠赤外線を利用した乾燥時間を短縮した穀物乾燥機であってもこうした要望にこたえるため、大型の穀物乾燥機の開発に着手する必要がある。しかしながら上記特許文献の構成を備える乾燥機をそのまま大型化するだけであっては、乾燥機の品質、性能、構成に支障をきたし、以下のような不具合が発生する場合がある。   In recent years, large-scale agriculture has been encouraged in recent agricultural reforms, and the demand for large-sized grain dryers has been increasing as grouping and commercialization are promoted. In order to meet these demands even with grain dryers that shorten the drying time using far-infrared rays, it is necessary to start development of large grain dryers. However, simply increasing the size of the dryer having the configuration of the above-mentioned patent document may hinder the quality, performance, and configuration of the dryer and may cause the following problems.

第一に、左右方向の乾燥部の延長化による乾燥通路の幅の均一化の維持が困難になるため、乾燥通路が場所によって薄厚が発生して、均一の通風と、穀物の均一な流下を損なうこととなり、穀物の乾燥を均一に行うことが出来なくなる可能性がある。   First, since it becomes difficult to maintain the uniform width of the drying passage by extending the drying section in the left-right direction, the drying passage is thin depending on the location, so that uniform ventilation and uniform grain flow are achieved. And the grain may not be dried uniformly.

第二に、乾燥機自体を大きくすることは、乾燥機の貯留槽に貯留する穀物の量が多くなり、乾燥部に加わる重量も増すこととなる。特に乾燥部自体を前後若しくは左右及びその両方の方向に延長させた場合においては、乾燥部に加わる重量に耐え、乾燥部の変形を防ぐために、乾燥部に使われる部材の厚さを増すか、重量に耐えうる構造に変更を余儀なくされ、従前に使用されている乾燥部の長さを延長するだけでは、その機能を果たさない結果となってしまう。また部材を厚くする、または荷重に耐える乾燥部の構造の新設計はコスト的に問題となり、商品価格の高騰をまねく結果となる。   Secondly, increasing the size of the dryer itself increases the amount of grain stored in the storage tank of the dryer and increases the weight applied to the drying section. In particular, in the case where the drying unit itself is extended in the front-rear or left-right direction and both directions, the thickness of the member used in the drying unit is increased in order to withstand the weight applied to the drying unit and prevent deformation of the drying unit, A structure that can withstand the weight is inevitably changed, and simply extending the length of the drying section that has been used before does not perform its function. Moreover, the new design of the structure of the dry part which can increase the thickness of the member or withstand the load is a problem in terms of cost, resulting in a rise in the product price.

第三に、乾燥部の大型化を行うことによって、乾燥部を通過する乾燥風の流れの不具合をきたし、通風しやすい場所と滞留しやすい場所の格差を増し、排塵風室に塵埃の堆積を増すばかりか、穀物を均一に乾燥する乾燥機の目的の達成が困難になる可能性があるので、乾燥部のそれぞれの場所に均一に乾燥風を通風するような装置を必要とするため、乾燥機自体のコストを高める結果となるものである。   Third, by increasing the size of the drying section, the flow of drying air that passes through the drying section has become defective, increasing the gap between places where ventilation is easy and where it is likely to stay, and accumulation of dust in the dust exhaust chamber. In addition, it may be difficult to achieve the purpose of the dryer that uniformly dries the grains, so it is necessary to have a device that uniformly blows the drying air at each location of the drying section. This results in an increase in the cost of the dryer itself.

第四に、乾燥部の横方向の延長に伴う集穀部の横方向の拡張により、集穀部中央への集穀を行うため集穀部の高さ延長する必要が発生し、集穀部内を流下する穀物と遠赤外線放射体との間隔が増すことによる、穀物への遠赤外線放射効率の低下をきたす事となる。   Fourthly, due to the lateral expansion of the cereal collection unit accompanying the lateral extension of the drying unit, it is necessary to extend the height of the cereal collection unit in order to collect cereals at the center of the cereal collection unit. The far-infrared radiation efficiency to the grain is reduced due to an increase in the distance between the grain that flows down and the far-infrared radiator.

そこで本発明では、上記の不具合を解消するように、乾燥部自体を大きく構成しても、部材の厚さを増す方法や、強度を増す構造を新たに設計しなくても従来の乾燥部の構造を利用して、荷重に耐え均一な乾燥層の幅を保って、乾燥風の乾燥層への均一な通風と穀物の均等な流下を可能とした乾燥部を提供すると共に、均一に乾燥風を熱風層と排風層と排風室に供給を行い、排風室内の通風の滞留を防止して、排風室内の塵埃の堆積を低減し、さらに、集穀部が横方向に拡張しても、穀物が散粒状に流下する部位に良好な間隔を保って遠赤外線放射体を配置し、効率よくしかも均一に穀物に遠赤外線を放射できるようにした遠赤外線穀物乾燥装置を提供することを目的とする。   Therefore, in the present invention, in order to eliminate the above-mentioned problems, even if the drying unit itself is configured to be large, the method of increasing the thickness of the member or the structure for increasing the strength is not newly designed. The structure is used to provide a drying section that can withstand the load and maintain a uniform width of the dry layer, allowing uniform air flow to the dry layer of the dry air and even flow of grains, and uniformly drying air. Is supplied to the hot air layer, the exhaust layer, and the exhaust chamber, preventing the accumulation of ventilation in the exhaust chamber, reducing the accumulation of dust in the exhaust chamber, and the cereal collection part is expanded laterally. However, it is possible to provide a far-infrared grain drying apparatus in which far-infrared radiators are arranged at good intervals at a part where grains flow down in a granular manner so that the far-infrared radiation can be efficiently and uniformly emitted to the grains. With the goal.

The reflector 35 for reflecting far-infrared rays radiated from the far-infrared radiator 17 is provided over the entire length of the cereal collecting flow path 12.

繰出しロール19はモータ(図示せず)によって回転し、それぞれの集穀流下路12の単位にモータを設けてそれぞれを駆動するか、または全ての繰出しロール19をチェーンで接続し、一つのモータで駆動させる方法でもよい。   The feeding roll 19 is rotated by a motor (not shown), and a motor is provided for each cereal collecting flow path 12 to drive each, or all the feeding rolls 19 are connected by a chain, and one motor is used. A driving method may be used.

遠赤外線放射体17は前後端に放射体が容易に回転できるように軸受37を備えており、その回転は繰出しロール19、または集穀装置14などの乾燥装置の一部の回転部から回転動力を伝達する方法や、単独にモータを備えて遠赤外線放射体17が一定の方向に回転するようになっている(図示せず)。   The far-infrared radiator 17 is provided with bearings 37 so that the radiator can be easily rotated at the front and rear ends, and the rotation of the far-infrared radiator 17 is a rotational power from a rotating part of the drying device such as the feeding roll 19 or the grain collector 14. The far-infrared radiator 17 is provided with a motor alone and rotates in a certain direction (not shown).

遠赤外線放射体17の後端には放射体内で燃焼する燃焼風を熱風室10に導く燃焼風ダクト36が接続されており、さらにその外周には集穀流下路12内の空間と熱風室10の吸引口38付近を繋ぐ温風ダクト39が備えられていて、送風機16の動作による吸引作用によって熱風室10内では、吸引口38から吸引される外気と、燃焼風ダクト36からは排出される燃焼風と、温風ダクト39からの温風を混合して乾燥に有用な乾燥風の生成を行う。なお、燃焼装置15が接続された遠赤外線放射体17の前端には、外気流入口40が設けられていて、温風ダクト39の吸引作用によって外気流入口40から外気を吸引し、前端の軸受37の冷却の後、集穀流下路12の空間内で発生する塵埃と共に温風ダクト39を流通し熱風室10に流入するようになっている。   Connected to the rear end of the far-infrared radiator 17 is a combustion air duct 36 that guides the combustion air combusted in the radiator to the hot air chamber 10. The hot air duct 39 connecting the vicinity of the suction port 38 is provided, and outside air sucked from the suction port 38 and exhausted from the combustion wind duct 36 in the hot air chamber 10 by the suction action by the operation of the blower 16. Combustion air and hot air from the hot air duct 39 are mixed to generate dry air useful for drying. An external airflow inlet 40 is provided at the front end of the far-infrared radiator 17 to which the combustion device 15 is connected, and external air is sucked from the external airflow inlet 40 by the suction action of the hot air duct 39, and the front end bearing is provided. After cooling 37, the hot air duct 39 flows through the hot air duct 39 together with dust generated in the space of the cereal collecting flow path 12.

集穀部4では二つの集穀流下路12の下端と乾燥装置底面とを繋ぐ仕切板41によって三つの空間を生成し、その左右方向を熱風室10、中央を排風室11として形成し、左右それぞれの熱風室10の吸引口38は乾燥機前後方向の中央を対称とした位置に設けられており、排風室11には2台の送風機16が備えられている。熱風室10の上方は乾燥風供給胴30と連通し、排風室11は排風胴31に連通されている。   In the grain collection unit 4, three spaces are generated by a partition plate 41 that connects the lower ends of the two grain collection flow paths 12 and the bottom surface of the drying device, and the left and right directions are formed as a hot air chamber 10 and the center as an exhaust air chamber 11, The suction ports 38 of the left and right hot air chambers 10 are provided at positions symmetrical with respect to the center in the front-rear direction of the dryer, and the air exhaust chamber 11 is provided with two fans 16. The upper part of the hot air chamber 10 communicates with the dry air supply cylinder 30, and the exhaust air chamber 11 communicates with the exhaust air cylinder 31.

揚穀装置5は内部をバケット23を備えるベルトが一方向に回転して穀物を上部に搬送するバケット昇降機であって、遠赤外線穀物乾燥装置1の前後方向に対する中央で、乾燥機の前面から若干の距離をおいて備えられている。この揚穀装置5のバケット昇降機の下部には、集穀部4の集穀装置14のスクリューコンベアで集穀した穀物をバケット昇降機内に投入するための張り込み口18が左右両方向に取り付けられており、それぞれの集穀装置14からの穀物が投入できるようになっている。なお、張り込み口18は外部から遠赤外線穀物乾燥装置1内に穀物を投入する場合のホッパーとして使用されるとよい。   The cerealing device 5 is a bucket elevator in which a belt provided with a bucket 23 rotates in one direction to convey the grain upward, and is slightly in the center of the far-infrared grain drying device 1 with respect to the front-rear direction and slightly from the front of the dryer. Are provided at a distance. In the lower part of the bucket elevator of this cerealing device 5, a filling port 18 for putting the grains collected by the screw conveyor of the cerealing device 14 of the cerealing unit 4 into the bucket elevator is attached in both the left and right directions. The grains from the respective grain collecting devices 14 can be input. In addition, the sticking port 18 is good to be used as a hopper when throwing grain into the far-infrared grain drying apparatus 1 from the outside.

揚穀装置5は上部のモータ22からの動力で回転して穀物を上方に搬送し、その排出口は、張り込み装置13の受入口と接合されていて、その受入口の下端には排出シュート34が備えられ、穀物を乾燥機の外部にここから排出することが出来るように、受入口のシャッタを設けて穀物の機内循環と、機外排出を選択することができる。張り込み装置13はモータ32によって螺旋を回転させて穀物を移動させるスクリューコンベアであって、張り込み装置13のその受入口を基点として、乾燥機の縦方向の中央線33に接する方向で、斜め後方に角度を持って備えられている。   The cerealing device 5 is rotated by power from the upper motor 22 to convey the grain upward, and its discharge port is joined to the receiving port of the embedding device 13, and a discharge chute 34 is provided at the lower end of the receiving port. In order to allow the grain to be discharged from here to the outside of the dryer, a shutter at the receiving port can be provided to select the in-machine circulation and the outside discharge of the grain. The tensioning device 13 is a screw conveyor that rotates a helix by a motor 32 to move the grain, and is obliquely rearward in a direction in contact with the longitudinal center line 33 of the dryer, with the receiving port of the tensioning device 13 as a base point. It is provided with an angle.

張り込み装置13の底部と貯留槽2の天井面には螺旋の回転によって搬送される穀物を、貯留槽2内に投入するための投入口A20と投入口B21を配置されており、この投入口はその開度をそれぞれ調節して投入の量を調節することができるようになっている(図5参照)。   An insertion port A20 and an insertion port B21 are disposed on the bottom of the embedding device 13 and the ceiling surface of the storage tank 2 to input the grains conveyed by spiral rotation into the storage tank 2. The opening amount can be adjusted to adjust the amount of charging (see FIG. 5).

さらに図6に示すように、揚穀装置5のバケット昇降機のモータ22を備えた上部だけ、若しくは全体を180°反転させて備えることも出来るように構成しているので、張り込み装置13は中央線33を基線として対称位置に備えられるようになっていて、張り込み装置13から貯留槽2内に投入するための投入口C24と投入口D25が備えられている。なお、揚穀装置5の上部の方向によって張り込み装置13が設置されない投入口が発生するので、使用されていない投入口には蓋が取り付けられ閉じられているものである。   Furthermore, as shown in FIG. 6, since it is comprised so that only the upper part provided with the motor 22 of the bucket elevator of the cerealing apparatus 5 or the whole can be reversed 180 degree | times, it is comprised so that the pasting apparatus 13 is a center line. 33 is provided at a symmetric position with the base line as a base line, and is provided with an inlet C24 and an inlet D25 for feeding into the storage tank 2 from the tensioning device 13. In addition, since the insertion port where the tensioning device 13 is not installed is generated depending on the direction of the upper portion of the cerealing device 5, a lid is attached to the unused insertion port and closed.

以上のように構成された遠赤外線穀物乾燥装置において、収穫後の穀物がトラック等の運搬装置から搬送機によって張り込み口18に投入され、揚穀装置5のバケット昇降機によって上方に揚穀されて、その排出口から張り込み装置13に移動し、螺旋の回転によって張り込み装置13の前方から斜め後方に向かって搬送され、投入口A20と投入口B21から貯留槽2内に投入される。   In the far-infrared grain drying apparatus configured as described above, the harvested grain is thrown into the loading port 18 by a transporter from a transport device such as a truck, and cerealed upward by a bucket lift of the cerealing device 5, It moves to the tensioning device 13 from the discharge port, is conveyed from the front of the tensioning device 13 obliquely rearward by the spiral rotation, and is charged into the storage tank 2 from the charging port A20 and the charging port B21.

通常の揚穀装置の排出方向が図5であるとすると、穀物は投入口A20と投入口B21から貯留槽2内に穀物が投入されるが、乾燥の後工程の方向によっては図6のように揚穀装置5の向きを変える必要があるので、その場合は揚穀装置5(バケット昇降機)の上部を180°反転させ、バケット23を取り付けたベルトの向きも反転させて設置し、張り込み装置13も中央線33を基線にして対称位置に向けて揚穀装置5の排出口と接続し、投入口C24と投入口D25を開口し、投入口A20と投入口B21に蓋をして閉じるようにする。   Assuming that the discharge direction of a normal cerealing device is FIG. 5, the cereal is input into the storage tank 2 from the input port A20 and the input port B21, but depending on the direction of the post-drying process, as shown in FIG. In that case, it is necessary to change the direction of the cerealing device 5, in that case, the upper part of the cerealing device 5 (bucket elevator) is inverted 180 °, the direction of the belt to which the bucket 23 is attached is also inverted, and installed. 13 is also connected to the outlet of the cerealing device 5 with the center line 33 as a base line toward the symmetrical position, opens the inlet C24 and the inlet D25, and closes the inlet A20 and the inlet B21 with a lid. To.

遠赤外線穀物乾燥装置への張込操作では、揚穀装置5に備える張り込み口18のどちらから一方若しくは両方から投入される穀物が、揚穀装置5によって張り込み装置13に達し、二つの投入口(A,B若しくはC、D)から投入され、穀物が貯留槽2内に堆積される。この張込操作は集穀部4に備える繰出しロール19を動作させないので、貯留槽2内に二つの山を築いて貯留槽内をほぼ均一に穀物が堆積する。   In the stretching operation to the far-infrared grain drying device, the grain fed from one or both of the tensioning ports 18 provided in the cerealing device 5 reaches the tensioning device 13 by the mashing device 5, and the two charging ports ( A, B or C, D) is input and the grains are deposited in the storage tank 2. Since this stretching operation does not operate the feeding roll 19 provided in the cereal collecting unit 4, two piles are built in the storage tank 2 and the grains are deposited almost uniformly in the storage tank.

張込操作終了後、次いで乾燥操作によって集穀部4の繰出しロール19が回転を開始し、穀物の流下及び循環が開始される。二つの集穀流下路12に取り付けられたそれぞれの繰出しロール19は均一に穀物を流下させるので、それぞれの乾燥体6を流下する穀物の流下速度も同一となる。   After completion of the tensioning operation, the feeding roll 19 of the cereal collecting unit 4 starts rotating by the drying operation, and the grain flow and circulation start. Since the feeding rolls 19 attached to the two cereal collecting flow paths 12 flow the grains uniformly, the flow speeds of the grains flowing down the respective dry bodies 6 are also the same.

集穀流下路12内部の遠赤外線放射体17は、高温になると線赤外線を発生する塗料を塗布してあるので、燃焼装置15での液体燃料の放射体内での燃焼によって、放射体自体が高温になり遠赤外線放射体17から遠赤外線を放射し、集穀流下路12を均一にしかも散粒状に流下する穀物に遠赤外線の照射を行う。遠赤外線放射体17の上方に設けられた反射板35によって、上方に放射された遠赤外線は下方に反射され、穀物に浴びせることが出来る。この遠赤外線放射体17は前後端に設けられた軸受37によって自在に回転するように構成されているので、乾燥機の一部の動力またはモータの回転を伝達することによって、遠赤外線放射体17を回転させて、その内部で燃焼する炎のあたる部分などの特に高温になる部分を転換することが出来るので、その遠赤放射性能と耐久性を向上させると共に、集穀流下路12内で穀物が散粒状に流下する場合に発生する塵埃が遠赤外線放射体17上面に堆積することを防止できるようになっている。   Since the far-infrared radiator 17 in the cereal flow downstream 12 is coated with a paint that generates linear infrared rays when the temperature becomes high, the radiator itself is heated by combustion of the liquid fuel in the radiator in the combustion device 15. The far-infrared rays are emitted from the far-infrared radiator 17 and the far-infrared rays are irradiated to the grains flowing down the cereal collecting flow path 12 uniformly and in a granular manner. The far-infrared radiation radiated upward is reflected downward by the reflector 35 provided above the far-infrared radiator 17 and can be put on the grain. Since the far-infrared radiator 17 is configured to freely rotate by bearings 37 provided at the front and rear ends, the far-infrared radiator 17 is transmitted by transmitting a part of the power of the dryer or the rotation of the motor. Can be turned to change the part that is particularly hot, such as the part of the flame that burns inside, so that the far-red radiation performance and durability can be improved, and the grain in the cereal collecting flow downstream 12 Can be prevented from being deposited on the upper surface of the far-infrared radiator 17.

図3、図4に示すように、送風機16を2台、集穀部4の排風室11に配置して、乾燥装置の左右方向に備えた二つの熱風室10で、それぞれの遠赤外線放射体17内で発生する燃焼装置15の燃焼風と、外気流入口40から外気が吸引されて軸受37を冷却しその後、集穀流下路12内を流通しながら集穀流下路12内で発生する塵埃と共に温風ダクト39を流通する空気と、吸引口38から流入する外気を混合して乾燥風を生成させて、送風機16の吸引作用によってそれぞれの乾燥風供給路30を上昇して乾燥体6に供給される。   As shown in FIG. 3 and FIG. 4, two blowers 16 are arranged in the wind exhaust chamber 11 of the grain collecting unit 4, and the two hot air chambers 10 provided in the left-right direction of the drying device are used to radiate far infrared rays. Combustion air generated in the body 17 and the outside air is sucked from the external airflow inlet 40 to cool the bearing 37 and then generated in the cereal flow downstream 12 while circulating in the cereal flow downstream 12. The air flowing through the warm air duct 39 together with the dust and the outside air flowing in from the suction port 38 are mixed to generate dry air, and the dry air supply passages 30 are lifted by the suction action of the blower 16 to raise the dry body 6. To be supplied.

遠赤外線の照射を受けた穀物は、その内部の温度を上昇させて、水分を穀物表面に移行させる事となるので、集穀流下路12で遠赤外線を照射した穀物は、揚穀装置5によって上昇し貯留槽2から乾燥部3に流下してそれぞれの乾燥体6に至り、乾燥風供給路30を上昇した乾燥風によって、その表面の水分を取除かれて穀物の乾燥が行われる。   Grain that has been irradiated with far-infrared rays raises its internal temperature and transfers moisture to the grain surface. Ascending, flowing down from the storage tank 2 to the drying unit 3 to reach the respective drying bodies 6, the moisture of the surface is removed by the drying air rising through the drying air supply path 30, and the grain is dried.

なお、二つの乾燥体6は、一方が180°反転して備えられているので、熱風層7と乾燥層8と排風層9のそれぞれが対向して配列されることとなり、送風機16からそれぞれの乾燥体6の対向する排風層9までの距離と、それぞれの吸引口38と燃焼風ダクト36及び温風ダクト39から熱風層7までの距離が同一であるので、吸引され外気と混合された乾燥風の熱風層への供給の風速、風量を同一とすることが出来る。例えば一方の乾燥体6を反転しないで配置した場合、それぞれの層と送風機16、燃焼装置15との風の流通距離が異なるので乾燥層8に通風される乾燥風がそれぞれの乾燥体6で異なる。特にそれぞれの排風層9と送風機16の距離が二つの乾燥体6で異なった場合には排風室9内で乱流が発生してそれぞれの乾燥層8の通風量が異なる現象が発生し、均一の乾燥が困難となる。   In addition, since the two dry bodies 6 are provided by inverting 180 °, the hot air layer 7, the dry layer 8, and the exhaust air layer 9 are arranged to face each other. Since the distance from the dry body 6 to the opposing exhaust air layer 9 and the distance from each suction port 38 to the combustion air duct 36 and the hot air duct 39 to the hot air layer 7 are the same, the air is sucked and mixed with the outside air. The air velocity and air volume of the dry air supplied to the hot air layer can be made the same. For example, when one of the dry bodies 6 is arranged without being inverted, the air flow distance between each layer, the blower 16 and the combustion device 15 is different, so that the dry air passed through the dry layer 8 is different for each dry body 6. . In particular, when the distance between each exhaust layer 9 and the blower 16 is different between the two dry bodies 6, turbulent flow is generated in the exhaust chamber 9 and a phenomenon occurs in which the air flow rate of each dry layer 8 is different. Uniform drying becomes difficult.

以上のように集穀流下路12で遠赤外線の放射を受けた穀物は、その下端に配置した集穀装置4で揚穀装置5方向に集められ、張り込み口18から揚穀装置5に投入され貯留槽2から乾燥部3を流下し、また集穀流下路12で遠赤外線の照射を受ける工程を循環し、設定の水分値まで乾燥の後、排出シュート34から排出されて後工程の作業へ移行する。   As described above, the cereal grains that have received far-infrared radiation in the cerealing flow downstream 12 are collected in the direction of the cerealing device 5 by the cerealing device 4 arranged at the lower end thereof, and are put into the cerealing device 5 from the filling port 18. The process of flowing down the drying unit 3 from the storage tank 2 and receiving irradiation of far-infrared rays in the cereal collecting flow path 12 is circulated, dried to the set moisture value, and then discharged from the discharge chute 34 to the subsequent process.
