Description

【0001】
【発明の属する技術分野】
本発明は、穀物を散粒状ないし薄層状に流動させながら遠赤外線を照射することにより、穀物を乾燥する遠赤外線利用穀物乾燥装置に関する。
【0002】
【従来の技術】
乾燥機本体の上段に穀物貯留槽、中段に通風乾燥部、下段に穀物取出槽をそれぞれ設け、穀物貯留槽に貯留した穀物を通風乾燥部、穀物取出槽、穀物貯留槽の経路で循環流動させながら通風乾燥部で通風乾燥する穀物乾燥機は、特公平5−22834号公報または特開平6−3052号公報に記載されており、この従来の穀物乾燥機においては、通風乾燥部の乾燥通路を流下する穀物に、乾燥通路の側面から乾燥通路を横切るように遠赤外線を照射することにより、遠赤外線による乾燥も併せて施して乾燥の効率化を図っている。
【0003】
ところが、上記従来の穀物乾燥機のように、通風乾燥部の乾燥通路を横切るように遠赤外線を照射するものでは、穀物が乾燥通路を充満状態で流下するところから、乾燥通路の遠赤外線を照射する側とその反対側とで、流下する穀物が遠赤外線によって受ける熱量にかなりの差異が生じ、乾燥通路の幅方向に乾燥ムラを起こして、穀物を均等に乾燥することができないことが分かった。
【0004】
そこで、本出願人は、先に、通風乾燥部から穀物が散粒状ないし薄層状に流下する穀物取出槽内に遠赤外線放射体を設けることにより、循環流動する穀物に遠赤外線を均等に照射して、乾燥ムラを起こすことなく、穀物を効率よく均等に乾燥することができる遠赤外線利用穀物乾燥機を提案するに至っている(特開平8−14745号公報参照)。
【0005】
【発明が解決しようとする課題】
しかしながら、上記特開平8−14745号公報に示すように、通風乾燥部から穀物が散粒状ないし薄層状に流下する穀物取出槽内では、穀物に混在する塵埃等が常時浮遊するので、穀物取出槽内に設けた遠赤外線放射体の上面に塵埃が堆積して発火の原因となり、火災発生の危険が大であることが判明した。
【0006】
また、穀物乾燥機で用いる遠赤外線放射体は、円筒体をその内部に熱を供給して加熱することにより外周に遠赤外線を放射させるものであるから、円筒体の上面側が下面側より温度が高くなって円周面の温度分布が均一にならず、このことが穀物に乾燥ムラを起こさせるだけでなく、遠赤外線の有効利用率が低下する原因になっていることも判明した。
【0007】
そこで、本発明は、遠赤外線放射体を回転させることにより、遠赤外線放射体の周面全体の温度分布を均一化し、散粒状ないし薄層状に流動する穀物に照射する遠赤外線を均等にして乾燥ムラの発生を防止するとともに、遠赤外線放射体の加熱度の高い上面側を順次下方に転換して流下する穀物と対向させて乾燥効率の向上を図ることができ、しかも、遠赤外線放射体に塵埃の堆積を無くして火災発生の危険を防止することができる遠赤外線利用穀物乾燥装置を提供することを目的とする。
【0008】
【課題を解決するための手段】
上記目的を達成するため、本発明に係る遠赤外線利用穀物乾燥装置は、散粒状ないし薄層状に流動する穀物に遠赤外線を照射して穀物を乾燥する遠赤外線利用穀物乾燥装置において、穀物が散粒状ないし薄層状に流動する部位に対向させて遠赤外線放射体を設け、この遠赤外線放射体を、遠赤外線放射体の加熱度の高い上面側が順次下方に転換して流下する穀物と対向するように回転させることを特徴とするものである。
【0009】
また、本発明に係る遠赤外線利用穀物乾燥装置は、乾燥機本体の上段に穀物貯留槽、中段に通風乾燥部、下段に穀物取出槽をそれぞれ設け、穀物貯留槽に貯留した穀物を通風乾燥部、穀物取出槽、穀物貯留槽の経路で循環流動させながら通風乾燥部で通風乾燥する穀物乾燥装置において、穀物取出槽内に、通風乾燥部から穀物が散粒状ないし薄層状に流下する穀物に遠赤外線を照射する遠赤外線放射体を設け、この遠赤外線放射体を時間の経過に伴って遠赤外線放射体の加熱度の高い上面側が順次下方に転換して流下する穀物と対向するように回転させることを特徴とするものである。
【0010】
そして、本発明は、この構成の遠赤外線利用穀物乾燥機において、遠赤外線放射体が円筒形であり、その一端の軸心にバーナの炎熱放射筒を臨ませ、かつ他端の軸心に排気筒を接続するとともに、遠赤外線放射体は円筒形の軸心を中心にして回転する構成とするのが好適である。
【0011】
また、本発明においては、遠赤外線放射体の外周面に摺接する払拭体を設けることが好適である。
【0012】
なお、本発明において、遠赤外線放射体の回転とは、連続一方向回転のほか、間欠一方向回転、連続または間欠交互回転、さらには上下反転などのように、遠赤外線放射体の、流動する穀物に対向する面を転換させる全ての手段である。
【0013】
【発明の実施の形態】
図面は本発明に係る遠赤外線利用穀物乾燥装置の一実施の形態を示しており、図1は遠赤外線利用穀物乾燥装置の全体縦断正面図、図2は同上縦断側面図、図3は一部の縦断背面図、図4は遠赤外線放射体の一部を破断して示す側面図、図5は同上斜視図である。
【0014】
1は乾燥機本体であって、乾燥機本体1の上段には穀物貯留槽2が、中段には通風乾燥部3が、さらに下段には穀物取出槽4がそれぞれ設けられている。穀物取出槽4の下部にはその前後方向全長にわたる穀物搬出コンベア5が設けられており、穀物搬出コンベア5と穀物貯留槽2の上部の上部コンベア6間は昇降機7によって連絡されていて、穀物搬出コンベア5、昇降機7および上部コンベア6を介して、穀物貯留槽2、通風乾燥部3、穀物取出槽4、穀物貯留槽槽2の経路で穀物が循環されるように構成されている。
【0015】
上記通風乾燥部3は通気壁により形成された複数の乾燥通路8をなしていて、その乾燥通路8を構成する熱風供給胴は、熱風供給室9に連通し、排風胴は排風室10に連通しており、排風室10には吸引送風機11が備えられている。
【0016】
穀物取出槽4は、その上部両側から穀物搬出コンベア5の搬送樋にかけて傾斜する流穀板12と両側壁13とで囲まれて形成されている。
【0017】
穀物取出槽4内には、遠赤外線放射体14が配設されており、この遠赤外線放射体14は、穀物取出槽4の前後方向略全長にわたる円筒形のものである。この遠赤外線放射体14から放射される遠赤外線は、通風乾燥部3の乾燥通路8から繰出ロール15の回転により繰り出されて、流穀板12面上を穀物が散粒状ないし薄層状に流下する穀物に照射される。遠赤外線放射体14の一端には、ガンタイプのバーナ16の炎熱放射筒17が軸心に臨ませてあり、遠赤外線放射体14の他端に排気筒18が軸心に接続されている。この排気筒18は熱風供給室9に導かれていて、その接続部に遠赤外線放射体14側から排気を吸引する吸引圧力調整器19が介在されている。遠赤外線放射体14は、燃料の燃焼により穀物の乾燥に適した波長の遠赤外線を放射するものである。
【0018】
上記遠赤外線放射体14の上方には、反射板20が設けられている。この反射板20は、遠赤外線放射体14から放射される遠赤外線を流穀板12,12の方向に拡散状に反射して、流穀板12の面上を流下する穀物に遠赤外線を均等に照射するためのものである。したがって、その形状および遠赤外線放射体14からの距離等は、流穀板12の面に向けて遠赤外線を均等に照射するのに適した状態に設定される。反射板20はアルミニウム、ステンレススチール等の磨き板で構成される。
【0019】
遠赤外線放射体14は、両端の軸支部21によって回転自在であり、遠赤外線放射体14のスプロケット22と前記繰出ロール15のスプロケット23とに懸架したチェーン24により、遠赤外線放射体14は繰出ロール15に連動して低速で連続回転するようになっている。なお、ガンタイプのバーナ6と排気筒18は遠赤外線放射体14の回転を妨げない構造でそれぞれ接続されている。25はチェーン24のテンション機構、26は循環穀物の除塵機、27は上部コンベア6の駆動モータである。
【0020】
以上のように構成された遠赤外線利用穀物乾燥装置において、穀物貯留槽2から通風乾燥部3の乾燥通路8を流下する穀物は、熱風供給室9から熱風供給胴を経て乾燥通路8を横切り排風胴に流通して排風室10に流通する吸引熱風で通風乾燥される。そして、通風乾燥部3で通風乾燥された穀物は、各乾燥通路8の下端にはそれぞれ備えられた繰出ロール15の回転により散粒状ないし薄層状をなして穀物取出槽4内の流穀板12上を流下し、その流下の過程で遠赤外線放射体14から遠赤外線が照射され、遠赤外線による乾燥が施される。
【0021】
遠赤外線放射体14は、繰出ロール15に連動して低速で回転しているので、上下で加熱ムラが生じてもその周面の温度分布は均一になる。このため、穀物取出槽4内の流穀板12上を流下する穀物に対して遠赤外線放射体14から照射される遠赤外線が均等になり、乾燥ムラが生じないばかりでなく、遠赤外線放射体14の加熱度の高い上面側が順次下方に転換して流下する穀物と対向するので、遠赤外線による乾燥効率が向上する。
【0022】
また、遠赤外線放射体14が乾燥中は回転し続けるので、その上面に塵埃が堆積することがなく、堆積塵埃の発火に起因する火災発生の危険を防止することができる。
【0023】
一方、遠赤外線放射体14の外周面に摺接する払拭体(図示せず)を設けることにより、遠赤外線放射体14の表面にある種の塵埃が焼付き状に付着することがあっても、それを確実に払拭することができ、遠赤外線放射体14の表面を常に清浄に保って、遠赤外線の放射効率を高く維持することができる。なお、この構成にすることにより、遠赤外線放射体14に対する塵埃の堆積防止をいっそう確実にすることができることは勿論である。
【0024】
【発明の効果】
本発明によれば、遠赤外線放射体を回転させることにより、遠赤外線放射体の周面全体の温度分布を均一化して、散粒状ないし薄層状に流動する穀物に照射する遠赤外線を均等にして乾燥ムラの発生を防止するとともに、遠赤外線放射体の加熱度の高い上面側を順次下方に転換して流下する穀物と対向させて乾燥効率の向上を図ることができ、しかも、遠赤外線放射体に塵埃の堆積を無くして火災発生の危険を防止することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a far-infrared grain drying apparatus that dries grains by irradiating far-infrared rays while flowing the grains in a granular or thin layer.
[0002]
[Prior art]
The upper part of the dryer body has a grain storage tank, the middle part has a ventilation drying section, and the lower stage has a grain extraction tank. The grains stored in the grain storage tank are circulated and flown through the path of the ventilation drying section, the grain extraction tank, and the grain storage tank. However, a grain dryer that performs ventilation drying in the ventilation drying section is described in Japanese Patent Publication No. 5-22834 or Japanese Patent Laid-Open No. 6-3052. In this conventional grain drying machine, the drying passage of the ventilation drying section is provided. By irradiating far-infrared rays to the flowing grain from the side of the drying passage so as to cross the drying passage, drying with far-infrared rays is also performed to improve drying efficiency.
[0003]
However, in the case of irradiating far-infrared rays so as to cross the drying passage of the ventilation drying section as in the conventional grain dryer, the far-infrared rays in the drying passage are irradiated from where the grains flow down in the dry passage. It was found that there was a considerable difference in the amount of heat received by far-infrared rays by the far-infrared grains on the flowing side and the opposite side, causing uneven drying in the width direction of the drying passage, so that the grains could not be dried evenly. .
[0004]
In view of this, the present applicant first irradiates far-infrared rays uniformly to the circulating and flowing grains by providing a far-infrared radiator in a grain take-out tank in which the grains flow from the ventilation drying section in a granular or thin layer. Thus, a far-infrared-use grain dryer capable of drying grains efficiently and uniformly without causing uneven drying has been proposed (see JP-A-8-14745).
[0005]
[Problems to be solved by the invention]
However, as shown in the above-mentioned JP-A-8-14745, in the grain take-out tank where the grains flow from the ventilation drying section in a granular or thin layer, dust mixed in the grains always floats. It was found that dust accumulated on the upper surface of the far-infrared radiator provided inside caused a fire and the risk of fire was great.
[0006]
In addition, the far-infrared radiator used in the grain dryer radiates far-infrared rays to the outer periphery by supplying heat to the inside of the cylinder and heating it. It became clear that the temperature distribution on the circumferential surface was not uniform and the temperature distribution was not uniform, which not only caused uneven drying of the grains, but also reduced the effective utilization of far infrared rays.
[0007]
Therefore, the present invention makes the temperature distribution of the entire peripheral surface of the far-infrared radiator uniform by rotating the far-infrared radiator, and the far-infrared rays irradiated to the grains flowing in a granular or thin layer are uniformly dried. In addition to preventing unevenness, the top side of the far-infrared radiator, which has a high degree of heating, can be sequentially turned downward to oppose the flowing grain to improve the drying efficiency. An object of the present invention is to provide a far-infrared grain drying apparatus capable of preventing the risk of fire by eliminating dust accumulation.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a far-infrared grain drying apparatus according to the present invention is a far-infrared grain drying apparatus for irradiating far-infrared rays to a grain that flows in a granular or thin layer to dry the grain. A far-infrared radiator is provided so as to face a part flowing in a granular or thin layer, and the far-infrared radiator is arranged so that the upper surface side of the far-infrared radiator, which has a high heating degree, is sequentially converted downward to face the flowing grain. It is characterized in that it is rotated.
[0009]
The far-infrared grain drying apparatus according to the present invention includes a grain storage tank in the upper stage of the dryer body, a ventilation drying section in the middle stage, and a grain take-out tank in the lower stage, and the ventilation drying section of the grains stored in the grain storage tank. In a grain drying device that circulates and flows in the passage of the grain take-out tank and grain storage tank and ventilates in the ventilation drying section, the grain is distant from the ventilation drying section in the grain extraction tank to the grains that flow in a granular or thin layer. A far-infrared radiator that irradiates infrared rays is provided, and this far-infrared radiator is rotated so that the upper surface side of the far-infrared radiator, which has a high degree of heating, gradually turns downward to face the falling grain as time passes. It is characterized by making it.
[0010]
In the far-infrared grain dryer having this configuration, the present invention has a far-infrared radiator having a cylindrical shape, with a flame heat radiation tube of a burner facing the axial center of one end thereof, and being discharged to the axial center of the other end. It is preferable to connect the cylinders and to rotate the far-infrared radiator around a cylindrical axis.
[0011]
Moreover, in this invention, it is suitable to provide the wiping body which slidably contacts the outer peripheral surface of a far-infrared radiator.
[0012]
In the present invention, the rotation of the far-infrared radiator refers to continuous one-way rotation, intermittent one-way rotation, continuous or intermittent alternating rotation, and further the flow of the far-infrared radiator such as upside down. All means of changing the face facing the grain.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
1 shows an embodiment of a far-infrared grain drying device according to the present invention. FIG. 1 is an overall longitudinal front view of the far-infrared grain drying device, FIG. 2 is a longitudinal side view of the same, and FIG. FIG. 4 is a side view showing a part of the far-infrared radiator broken away, and FIG. 5 is a perspective view of the same.
[0014]
Reference numeral 1 denotes a dryer body. A grain storage tank 2 is provided in the upper stage of the dryer body 1, a ventilation drying unit 3 is provided in the middle stage, and a grain take-out tank 4 is provided in the lower stage. A grain carry-out conveyor 5 is provided at the lower part of the grain take-out tank 4 in the longitudinal direction, and the grain carry-out conveyor 5 and the upper conveyor 6 at the upper part of the grain storage tank 2 are connected by an elevator 7 to carry out the grain carry-out. Through the conveyor 5, the elevator 7 and the upper conveyor 6, the grain is circulated through the path of the grain storage tank 2, the ventilation drying unit 3, the grain take-out tank 4, and the grain storage tank 2.
[0015]
The ventilation drying section 3 has a plurality of drying passages 8 formed by ventilation walls. A hot air supply cylinder constituting the drying passage 8 communicates with a hot air supply chamber 9, and an exhaust wind cylinder is an exhaust chamber 10. The exhaust fan 10 is provided with a suction fan 11.
[0016]
The grain take-out tank 4 is formed by being surrounded by a drifted grain plate 12 and both side walls 13 that are inclined from both upper sides of the grain take-out tank 4 to the conveying basket of the grain carry-out conveyor 5.
[0017]
A far-infrared radiator 14 is disposed in the grain take-out tank 4, and the far-infrared radiator 14 has a cylindrical shape extending over the entire length of the grain take-out tank 4 in the front-rear direction. The far-infrared rays emitted from the far-infrared radiator 14 are drawn out from the drying passage 8 of the ventilation drying unit 3 by the rotation of the feeding roll 15, and the grains flow down on the surface of the flown cereal plate 12 in a granular or thin layer. Irradiated to the grain. At one end of the far-infrared radiator 14, a flame heat radiation cylinder 17 of a gun-type burner 16 faces the axis, and an exhaust cylinder 18 is connected to the other end of the far-infrared radiator 14 at the axis. The exhaust cylinder 18 is led to the hot air supply chamber 9, and a suction pressure adjuster 19 for sucking exhaust gas from the far-infrared radiator 14 side is interposed at the connection portion. The far-infrared radiator 14 emits far-infrared rays having a wavelength suitable for drying grains by burning fuel.
[0018]
A reflection plate 20 is provided above the far-infrared radiator 14. The reflecting plate 20 reflects far infrared rays emitted from the far infrared radiator 14 in a diffused manner toward the flowing grain plates 12, 12 so that the far infrared rays are evenly applied to the grains flowing down on the surface of the flowing grain plate 12. For irradiating. Therefore, the shape, the distance from the far-infrared radiator 14, and the like are set to a state suitable for evenly irradiating far-infrared rays toward the surface of the drifted grain board 12. The reflector 20 is made of a polished plate such as aluminum or stainless steel.
[0019]
The far-infrared radiator 14 is rotatable by the shaft support portions 21 at both ends, and the far-infrared radiator 14 is fed by a chain 24 suspended from a sprocket 22 of the far-infrared radiator 14 and a sprocket 23 of the feeding roll 15. 15 is continuously rotated at a low speed. The gun-type burner 6 and the exhaust pipe 18 are connected to each other with a structure that does not prevent the rotation of the far-infrared radiator 14. 25 is a tension mechanism of the chain 24, 26 is a dust remover for circulating grains, and 27 is a drive motor for the upper conveyor 6.
[0020]
In the far-infrared grain drying apparatus configured as described above, the grain flowing down from the grain storage tank 2 through the drying passage 8 of the ventilation drying unit 3 crosses the drying passage 8 from the hot air supply chamber 9 through the hot air supply cylinder. It is ventilated with hot hot air that flows through the wind tunnel and flows into the exhaust chamber 10. The grains dried by ventilation in the ventilation drying unit 3 are formed in a granular or thin layer by rotation of the feed roll 15 provided at the lower end of each drying passage 8 to form a drifting grain plate 12 in the grain extraction tank 4. The far-infrared radiator 14 emits far-infrared rays in the process of flowing down, and drying by far-infrared rays is performed.
[0021]
Since the far-infrared radiator 14 rotates at a low speed in conjunction with the feeding roll 15, even if heating unevenness occurs in the upper and lower sides, the temperature distribution on the peripheral surface becomes uniform. For this reason, the far-infrared rays irradiated from the far-infrared radiator 14 to the grains flowing down on the flowing grain plate 12 in the grain take-out tank 4 are equalized, so that drying unevenness does not occur, and the far-infrared radiator Since the upper surface side with a high heating degree of 14 changes to the grain which flows down and flows down sequentially, the drying efficiency by far-infrared rays improves.
[0022]
In addition, since the far-infrared radiator 14 continues to rotate during drying, dust does not accumulate on the upper surface of the far-infrared radiator 14, and the risk of fire due to ignition of accumulated dust can be prevented.
[0023]
On the other hand, by providing a wiping body (not shown) that is in sliding contact with the outer peripheral surface of the far-infrared radiator 14, even if some kinds of dust adhere to the surface of the far-infrared radiator 14 in a seizure state, It can be wiped off reliably, and the surface of the far-infrared radiator 14 can always be kept clean, and the far-infrared radiation efficiency can be kept high. It goes without saying that this configuration can further prevent dust accumulation on the far-infrared radiator 14.
[0024]
【The invention's effect】
According to the present invention, by rotating the far-infrared radiator, the temperature distribution of the entire peripheral surface of the far-infrared radiator is made uniform, and the far-infrared rays irradiated to the grains flowing in a granular or thin layer are made uniform. In addition to preventing the occurrence of uneven drying, the top side of the far-infrared radiator, which has a high degree of heating, can be sequentially turned downward to oppose the flowing grain to improve the drying efficiency, and the far-infrared radiator It is possible to prevent the risk of fire by eliminating the accumulation of dust.
