Description
本発明は、穀粒循環形態の穀物乾燥機に関するものである。 The present invention relates to a grain dryer in a grain circulation form.
一般に、穀粒循環形態の穀物乾燥機は、乾燥部において熱風を通風して穀物を乾燥し、乾燥部で発生した排風を排風室から機外へと排出する仕組みとなっている。ここで、外気温度が低いときに高水分穀物の乾燥を行うと、乾燥部で高温多湿となった排風が、排風室で冷却されて排風室の内壁に結露が生じることがある。この結露によって、排風室内を流下して還流される穀物に露が付着したり、排風室内に夾雑物が付着・堆積したりする不具合が生じる。 In general, a grain dryer in a grain circulation mode has a mechanism in which hot air is blown through a drying portion to dry grains, and exhaust air generated in the drying portion is discharged from an exhaust chamber to the outside of the machine. Here, if the high-moisture grains are dried when the outside air temperature is low, the exhaust air that has become hot and humid in the dried portion may be cooled in the exhaust air chamber and dew condensation may occur on the inner wall of the exhaust air chamber. Due to this dew condensation, dew adheres to the grains that flow down and return in the exhaust chamber, and impurities adhere and accumulate in the exhaust chamber.
そこで、特許文献１には、排風室の内壁に機外から直接外気を導入する外気導入口を設けることによって噴風を発生させて排風室の内壁に付着した露を吹き飛ばし、排風とともに露を機外排出するようにして上記不具合を防止するようにした穀物乾燥機が開示されている。 Therefore, in Patent Document 1, by providing an outside air introduction port for directly introducing outside air from the outside of the machine on the inner wall of the exhaust chamber, a blast is generated to blow off the dew adhering to the inner wall of the exhaust chamber, together with the exhaust air. A grain dryer is disclosed in which dew is discharged from the machine to prevent the above-mentioned problems.
しかしながら、一般に、排風室内は、穀物の乾燥に伴い塵埃が発生しやすいため、外気温度と排風温度の温度差が大きい場合には、外気導入口から排風室内に外気を導入すると、外気によって急激に冷却された排風と塵埃によって結露が促進されて、上記不具合を十分に防止できないという問題があった。 However, in general, dust is likely to be generated in the exhaust air chamber as the grains dry. Therefore, when the temperature difference between the outside air temperature and the exhaust air temperature is large, when the outside air is introduced into the exhaust air chamber from the outside air inlet, the outside air is introduced. There is a problem that dew condensation is promoted by the exhaust air and dust rapidly cooled by the air, and the above-mentioned problems cannot be sufficiently prevented.
そこで、本発明は、外気温度と排風温度の温度差が大きい場合においても、排風室内の結露を好適に防止することができる穀物乾燥機を提供することを目的とするものである。 Therefore, an object of the present invention is to provide a grain dryer capable of suitably preventing dew condensation in the exhaust air chamber even when the temperature difference between the outside air temperature and the exhaust air temperature is large.

前記外気導入装置が外気導入口の開口面積を調節可能とする調節手段を備えることによって達成される。
本発明によれば、外気導入口を開閉可能な外気導入装置が設けられているので、外気温度と排風温度の温度差が所定温度以下のときに、外気導入装置によって外気導入口を開状態にして、外気を排風室に導入することにより、排風室内の塵埃を乾かしながら機外へ除去することができる。これにより、塵埃が結露することを未然に防止できる。他方で、外気温度と排風温度の温度差が所定温度より大きいときは、排風室内に結露が発生しやすいため、外気導入装置によって外気導入口を閉状態にして、外気導入口を閉鎖することにより、排風室内への低い温度の外気の導入を防いで結露の発生を抑止することができる。その結果、排風室内の結露を好適に防止することが可能になる。

また、図８に示されるように、開閉調節板１１１の右上隅角部及び左上隅角部に、それぞれ、基板１１０の取付孔Ｘ１，Ｘ２と対応する取付孔Ｙ１，Ｙ２が設けられており、開閉調節板１１１の略中央かつ凹状切欠き部１１３の下方近傍に、円柱凸部Ｖを挿通するための円状孔Ｗが設けられている。また、取付孔Ｙ１，Ｙ２及び円状孔Ｗの下方には、これらと所定幅だけ位置をずらして、位置調節取付孔Ｙ１´，Ｙ２´及び位置調節円状孔Ｗ´がそれぞれ設けられている。さらに、円状孔Ｗを対象点として右上隅角部の取付孔Ｙ１と点対象となる位置に取付孔Ｚ１が設けられており、左上隅角部の取付孔Ｙ２と点対象となる位置に取付孔Ｚ２が設けられている。 Further, as shown in FIG. 8, mounting holes Y1 and Y2 corresponding to the mounting holes X1 and X2 of the substrate 110 are provided in the upper right corner portion and the upper left corner portion of the opening / closing adjustment plate 111, respectively. A circular hole W for inserting the cylindrical convex portion V is provided at substantially the center of the opening / closing adjustment plate 111 and in the vicinity of the lower side of the concave notch portion 113. Further, below the mounting holes Y1 and Y2 and the circular hole W, the position adjusting mounting holes Y1'and Y2' and the position adjusting circular hole W'are provided respectively by shifting the positions by a predetermined width from these. .. Further, a mounting hole Z1 is provided at a position that is a point target with the mounting hole Y1 at the upper right corner with the circular hole W as a target point, and is mounted at a position that is a point target with the mounting hole Y2 at the upper left corner. Hole Z2 is provided.
ここで、外気導入装置１０９が開状態の場合は、円柱凸部Ｖは円状孔Ｗに挿通されてナットで固定され、取付孔Ｘ１と取付孔Ｙ１、取付孔Ｘ２と取付孔Ｙ２が、それぞれ手動操作可能な蝶ボルトで固定されて、開閉調節板１１１が基板１１０に取り付けられる。 Here, when the outside air introduction device 109 is in the open state, the cylindrical convex portion V is inserted into the circular hole W and fixed with a nut, and the mounting hole X1 and the mounting hole Y1 and the mounting hole X2 and the mounting hole Y2 are respectively. The opening / closing adjustment plate 111 is attached to the substrate 110 by being fixed with a manually operable wing bolt.
外気導入装置１０９が閉状態のとき、開閉調節板１１１が円柱凸部Ｖに挿通された円状孔Ｗを中心として、開状態から１８０度回動して上下反転され、取付孔Ｘ１と取付孔Ｚ１、取付孔Ｘ２と取付孔Ｚ２がそれぞれ手動操作可能な蝶ボルトで固定される。このとき、円状孔Ｗを対象点として右上隅角部の取付孔Ｙ１と点対象となる位置に取付孔Ｚ１が設けられており、左上隅角部の取付孔Ｙ２と点対象となる位置に取付孔Ｚ２が設けられているため、作業者は、蝶ボルトの着脱操作に加え、円柱凸部Ｖが円状孔Ｗに挿通された状態で、開閉調節板１１１が円柱凸部Ｖに挿通された円状孔Ｗを中心として、１８０度回動して上下反転する操作によって、簡単に外気導入装置１０９の開状態と閉状態とを容易に切替えることができるため、便利である。 When the outside air introduction device 109 is in the closed state, the opening / closing adjusting plate 111 is rotated 180 degrees from the open state and turned upside down around the circular hole W inserted through the cylindrical convex portion V, and the mounting hole X1 and the mounting hole Z1, the mounting hole X2 and the mounting hole Z2 are each fixed with manually operable wing bolts. At this time, the mounting hole Z1 is provided at a position to be point-symmetrical with the mounting hole Y1 at the upper right corner with the circular hole W as the target point, and is at a position to be point-polished with the mounting hole Y2 at the upper left corner. Since the mounting hole Z2 is provided, in addition to the operation of attaching and detaching the wing bolt, the operator inserts the opening / closing adjustment plate 111 into the cylindrical convex portion V while the cylindrical convex portion V is inserted into the circular hole W. It is convenient because the open state and the closed state of the outside air introduction device 109 can be easily switched by the operation of rotating 180 degrees around the circular hole W and turning it upside down.
また、外気導入装置１０９の外気導入口１１４の開口面積を調節する場合、作業者は、円柱凸部Ｖを円状孔Ｗ´に挿通してナットで固定し、取付孔Ｘ１が位置調節取付孔Ｙ１´と、取付孔Ｘ２が位置調節取付孔Ｙ２´と対応するように蝶ボルトで開閉調節板１１１を基板１１０に取り付けることにより、開閉調節板１１１を所定幅だけ上方に位置をずらして基板１１０に取り付けることが可能となる。その結果、外気導入部１１２及びこれと連通する外気導入口１１４の開口面積を調節することができる。 Further, when adjusting the opening area of the outside air introduction port 114 of the outside air introduction device 109, the operator inserts the cylindrical convex portion V into the circular hole W'and fixes it with a nut, and the mounting hole X1 is a position adjusting mounting hole. By attaching the opening / closing adjustment plate 111 to the board 110 with a wing bolt so that Y1'and the mounting hole X2 correspond to the position adjusting mounting hole Y2', the opening / closing adjustment plate 111 is displaced upward by a predetermined width to the board 110. It can be attached to. As a result, the opening area of the outside air introduction portion 112 and the outside air introduction port 114 communicating with the outside air introduction portion 112 can be adjusted.
このように、取付孔Ｙ１，Ｙ２及び円状孔Ｗと対応して、所定幅だけ位置をずらして位置調節取付孔Ｙ１´，Ｙ２´及び位置調節円状孔Ｗ´を設け、外気導入口１１４の開口面積の調節を可能とすれば、外気温度に応じて外気導入口１１４の開口面積を調節することができる。 In this way, the position adjusting mounting holes Y1', Y2'and the position adjusting circular hole W'are provided by shifting the positions by a predetermined width corresponding to the mounting holes Y1 and Y2 and the circular hole W, and the outside air introduction port 114 If the opening area of the outside air can be adjusted, the opening area of the outside air introduction port 114 can be adjusted according to the outside air temperature.
図８においては、取付孔Ｙ１，Ｙ２及び円状孔Ｗと対応し、位置調節取付孔Ｙ１´，Ｙ２´及び位置調節円状孔Ｗ´が設けられているが、これらに対応する取付孔をさらに増やせば、外気導入口１１４の開口面積の調節をより細かく行うことが可能となる。例えば、図８において、取付孔Ｙ１と取付孔Ｚ２を結ぶ直線上、及び、取付孔Ｙ１と取付孔Ｚ２を結ぶ直線上に複数の取付孔を設けることで、基板１１０に対する開閉調節板１１１の取付位置をより細かく調節でき、その結果、外気導入装置１０９の外気導入口１１４の開口面積をより細かく調節できる。これにより、外気温度に応じた細かい外気導入量の調節が可能となる。 In FIG. 8, the position adjusting mounting holes Y1 ′, Y2 ′ and the position adjusting circular hole W ′ are provided corresponding to the mounting holes Y1 and Y2 and the circular hole W. If the number is further increased, the opening area of the outside air introduction port 114 can be finely adjusted. For example, in FIG. 8, by providing a plurality of mounting holes on a straight line connecting the mounting holes Y1 and the mounting holes Z2 and on the straight line connecting the mounting holes Y1 and the mounting holes Z2, the opening / closing adjustment plate 111 is mounted on the substrate 110. The position can be finely adjusted, and as a result, the opening area of the outside air introduction port 114 of the outside air introduction device 109 can be finely adjusted. This makes it possible to finely adjust the amount of outside air introduced according to the outside air temperature.
このような構成によって、外気温度と排風温度の温度差が所定温度以下のときは、外気導入装置１０９によって外気導入口１１４を開状態にして、外気を排風室１０８に導入することにより、排風室１０８内の塵埃を乾かしながら機外へ除去することができる。これにより、塵埃が結露することを未然に防止できる。 With such a configuration, when the temperature difference between the outside air temperature and the exhaust air temperature is equal to or less than a predetermined temperature, the outside air introduction port 114 is opened by the outside air introduction device 109 and the outside air is introduced into the exhaust air chamber 108. The dust in the exhaust chamber 108 can be removed to the outside of the machine while being dried. As a result, it is possible to prevent dew condensation of dust.
他方で、外気温度と排風温度の温度差が所定温度より大きいときは、排風室１０８内に結露が発生しやすいため、外気導入装置１０９によって外気導入口１１４を閉状態にして閉鎖することにより、排風室内への低い温度の外気の導入を防いで結露の発生を抑止することができる。その結果、排風室内の結露を好適に防止することが可能になる。 On the other hand, when the temperature difference between the outside air temperature and the exhaust air temperature is larger than the predetermined temperature, dew condensation is likely to occur in the exhaust air chamber 108. Therefore, the outside air introduction port 114 is closed by the outside air introduction device 109. As a result, it is possible to prevent the introduction of low-temperature outside air into the ventilation chamber and suppress the occurrence of dew condensation. As a result, it becomes possible to suitably prevent dew condensation in the exhaust air chamber.
さらに、外気導入装置１０９の外気導入口１１４の開口面積を調節する調節手段が設けられていることにより、外気導入口１１４の開口面積を調節することができるため、外気温度に対して外気の導入量を調節することによって、適切な外気導入を行うことができ、その結果、排風室１０９内の結露をさらに好適に防止できる。 Further, since the adjusting means for adjusting the opening area of the outside air introduction port 114 of the outside air introduction device 109 is provided, the opening area of the outside air introduction port 114 can be adjusted, so that the outside air can be introduced with respect to the outside air temperature. By adjusting the amount, appropriate outside air can be introduced, and as a result, dew condensation in the exhaust chamber 109 can be more preferably prevented.
本発明は、以上の実施形態に限定されることなく、特許請求の範囲に記載された発明の範囲内で種々の変更が可能であり、それらも本発明の範囲内に包含されるものであることはいうまでもない。 The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
例えば、前記実施形態においては、外気導入装置１０９の基板１１０は、矩形の板状部材によって形成されており、上側略中央部及び下側略中央部に、それぞれ、機体外壁１００の正面に基板１１０をボルトで固定するための取付孔Ｚ１，Ｚ２を設けて、機体外壁１００の正面に固定する構成としたが、これを機体外壁１００に対して着脱可能な点検蓋として設けてもよい。これにより、排風室１０８内の点検をし易くすることができる。加えて、排風室内の露や塵埃や夾雑物の除去作業も容易となる。 For example, in the above embodiment, the substrate 110 of the outside air introduction device 109 is formed of a rectangular plate-shaped member, and the substrate 110 is formed in the upper substantially central portion and the lower substantially central portion, respectively, in front of the outer wall 100 of the machine body. The mounting holes Z1 and Z2 for fixing the above body with bolts are provided and fixed to the front surface of the outer wall 100 of the machine body, but this may be provided as an inspection lid that can be attached to and detached from the outer wall 100 of the machine body. This makes it easier to inspect the inside of the exhaust chamber 108. In addition, the work of removing dew, dust and impurities in the ventilation chamber becomes easy.
また、前記実施形態においては、外気導入口１１４の開口面積を調節する調節手段として、開閉調節板１１１の基板１１０に対する取付位置を調節可能とする位置調節取付孔Ｙ１´，Ｙ２´及び位置調節円状孔Ｗ´を設けたが、外気導入装置９の開閉調節板１１１を、基板１１０に対し所定範囲で外気導入部１１４の開閉方向（図８の上下方向）へスライド移動可能に構成し、さらに図９に示されるように、制御部２０１の出力側に、外気導入口開閉ソレノイド１１５を設け、この外気導入口開閉ソレノイド１１５によって、開閉調節板１１１のスライド移動を制御する構成としてもよい。このように、外気導入装置９に、外気導入部１１４を制御部２０１によって開閉制御可能とした開閉制御手段を設けることによって、外気導入口１１４の開閉制御が可能となり、外気温度を取得する外気温度検出手段の検出値に応じて開閉制御することができる。これにより、制御部２０１が、外気温度検出手段によって取得した外気温度の計測値と、熱風温度検出手段によって取得した排風温度とを参照し、外気温度と排風温度の温度差が所定温度以下のときに、外気導入装置によって外気導入口を開状態となるように制御すれば、外気を排風室に導入することにより、排風室内の塵埃を乾かしながら機外へ好適に除去することができる。外気温度と排風温度の温度差が所定温度より大きいとき、外気導入装置１０９によって外気導入口１１４を閉状態となるように制御して閉鎖することにより、排風室内への低い温度の外気の導入を防いで結露の発生を抑止することができる。これにより、外気温度に応じて適切な外気導入及び外気閉鎖を行い、結露を好適に防止できる。また、制御部２０１が、外気温度検出手段によって取得した外気温度の計測値に応じて、外気導入口１１４の開口面積を調節するように開閉調節板１１１のスライド移動を制御すれば、外気温度に応じた外気導入口１１４の開閉制御が可能となり、より好適に、排風室１０８内の結露を防止できる。例えば、制御部２０１が、外気温度と排風温度の温度差を計算し、温度差が大きいほど、外気導入口１１４の開口面積が小さくなるように制御し、排風室１０８内への外気導入量を低減するように構成すれば、外気温度に応じて、より好適に、排風室１０８内の結露を防止できる。 Further, in the above embodiment, as the adjusting means for adjusting the opening area of the outside air introduction port 114, the position adjusting mounting holes Y1'and Y2' and the position adjusting circles that enable the mounting position of the opening / closing adjusting plate 111 with respect to the substrate 110 can be adjusted. Although the shape hole W'is provided, the opening / closing adjustment plate 111 of the outside air introduction device 9 is configured to be slidable in the opening / closing direction (vertical direction in FIG. 8) of the outside air introduction portion 114 within a predetermined range with respect to the substrate 110. As shown in FIG. 9, the outside air introduction port opening / closing solenoid 115 may be provided on the output side of the control unit 201, and the opening / closing adjustment plate 111 may be controlled to slide by the outside air introduction port opening / closing solenoid 115. In this way, by providing the outside air introduction device 9 with an opening / closing control means capable of opening / closing the outside air introduction unit 114 by the control unit 201, the opening / closing control of the outside air introduction port 114 becomes possible, and the outside air temperature for acquiring the outside air temperature is obtained. Opening and closing can be controlled according to the detection value of the detecting means. As a result, the control unit 201 refers to the measured value of the outside air temperature acquired by the outside air temperature detecting means and the exhaust air temperature acquired by the hot air temperature detecting means, and the temperature difference between the outside air temperature and the exhaust air temperature is equal to or less than the predetermined temperature. At this time, if the outside air introduction port is controlled to be in the open state by the outside air introduction device, the dust in the exhaust air chamber can be appropriately removed to the outside of the machine while being dried by introducing the outside air into the exhaust air chamber. it can. When the temperature difference between the outside air temperature and the exhaust air temperature is larger than the predetermined temperature, the outside air introduction port 114 is controlled to be closed by the outside air introduction device 109 and closed, so that the outside air at a low temperature into the exhaust chamber is closed. It is possible to prevent the introduction and prevent the occurrence of dew condensation. As a result, dew condensation can be suitably prevented by appropriately introducing the outside air and closing the outside air according to the outside air temperature. Further, if the control unit 201 controls the slide movement of the opening / closing adjusting plate 111 so as to adjust the opening area of the outside air introduction port 114 according to the measured value of the outside air temperature acquired by the outside air temperature detecting means, the outside air temperature can be obtained. It is possible to control the opening and closing of the outside air introduction port 114 according to the situation, and more preferably, it is possible to prevent dew condensation in the exhaust chamber 108. For example, the control unit 201 calculates the temperature difference between the outside air temperature and the exhaust air temperature, controls so that the larger the temperature difference, the smaller the opening area of the outside air introduction port 114, and introduces the outside air into the exhaust air chamber 108. If the amount is reduced, dew condensation in the exhaust chamber 108 can be more preferably prevented depending on the outside air temperature.
また、外気温度検出手段の検出値とともに水分検出手段の検出値に応じて外気導入装置１０９の外気導入口１１４を開閉制御するように構成してもよい。このとき、外気温度が１５度以下で運転中に穀物水分が２０％以上の場合は外気導入口１１４を閉制御し、２０％以下では開制御して乾燥運転を行うようにしてもよい。これにより、穀物の高水分時には、乾燥速度が速くその分排風の湿度が高くなるため、排風室１０８内が結露しやすいが、水分が低下すると、結湿度が低くなり結露しにくいため、外気導入口１１４を開制御することにより、漏斗状底板１０８ａに滞留する塵埃を吹き飛ばすことができる。 Further, the opening / closing control of the outside air introduction port 114 of the outside air introduction device 109 may be controlled according to the detection value of the outside air temperature detecting means and the detection value of the moisture detecting means. At this time, if the outside air temperature is 15 degrees or less and the grain moisture content is 20% or more during operation, the outside air introduction port 114 may be closed and controlled, and if it is 20% or less, the opening control may be performed to perform the drying operation. As a result, when the grain has a high moisture content, the drying speed is high and the humidity of the exhaust air is increased accordingly, so that the inside of the exhaust air chamber 108 is likely to condense. By controlling the opening of the outside air introduction port 114, it is possible to blow off the dust accumulated in the funnel-shaped bottom plate 108a.
また、外気温度がある閾値以下で運転中に穀物水分が２０％以上の場合には外気導入口１１４を閉制御し、２０％以下では開制御して、乾燥運転してもよい。さらに、この閾値は、穀物乾燥機１に設けた操作盤１０３から、制御部２０１が備えるシステムに、設定可能に構成し、例えば、１０度、１５度、２０度というように設定する閾値を変更可能に構成してもよい。これにより、結露防止に適切となるように開閉制御を調節し、漏斗状底板１０８ａに滞留する塵埃を吹き飛ばすことができる。 Further, when the outside air temperature is below a certain threshold value and the grain moisture content is 20% or more during operation, the outside air introduction port 114 may be controlled to be closed, and when it is 20% or less, it may be controlled to be opened to perform a dry operation. Further, this threshold value can be set in the system provided in the control unit 201 from the operation panel 103 provided in the grain dryer 1, and the threshold values set as, for example, 10 degrees, 15 degrees, and 20 degrees are changed. It may be configured as possible. Thereby, the opening / closing control can be adjusted so as to be appropriate for preventing dew condensation, and the dust accumulated in the funnel-shaped bottom plate 108a can be blown off.
さらに、穀物乾燥機１に設けた操作盤１０３から、制御部２０１が備えるシステムに、穀物種類を設定可能に構成し、穀物種類の設定に応じて、設定された閾値を増減して開閉制御するように構成してもよい。例えば、閾値は、籾のときは設定された閾値の温度より高く、小麦のときは低くなるように、開閉制御する。これは、小麦は籾よりも水分を出しやすく結露しやすいためである。これにより、穀物種類に応じて、好適に結露を防止できる。また、制御部２０１は、穀物種類に応じて外気導入口１１４の開閉を決定してもよい。例えば、籾のときは一律に開制御、小麦のときは一律に閉制御するよう構成する。 Further, the operation panel 103 provided in the grain dryer 1 is configured so that the grain type can be set in the system provided in the control unit 201, and the opening / closing control is performed by increasing / decreasing the set threshold value according to the setting of the grain type. It may be configured as follows. For example, the opening / closing control is performed so that the threshold value is higher than the set threshold temperature in the case of paddy and lower in the case of wheat. This is because wheat is more likely to release water and condense than paddy. Thereby, dew condensation can be suitably prevented depending on the type of grain. Further, the control unit 201 may decide to open / close the outside air introduction port 114 according to the type of grain. For example, in the case of paddy, it is configured to be uniformly open-controlled, and in the case of wheat, it is configured to be uniformly closed-controlled.
さらに、制御部２０１が、張込穀粒量検出センサから穀物の張込量を取得し、張込量が所定量より少ないときは、設定された閾値の温度より高く、所定量より多いときは低くなるように、開閉制御してもよい。張込量が多い方が結露しやすくなるためである。また、制御部２０１は、張込量に応じて外気導入口１１４の開閉を決定してもよい。例えば、張込量が所定量より少ないときは一律に開制御、張込量が所定量より多いときは一律に閉制御するよう構成する。 Further, the control unit 201 acquires the grain filling amount from the filling grain amount detection sensor, and when the filling amount is less than the predetermined amount, it is higher than the set threshold temperature, and when it is larger than the predetermined amount, it is higher than the predetermined threshold amount. Opening and closing may be controlled so as to be low. This is because the larger the amount of squeeze, the easier it is for condensation to form. Further, the control unit 201 may decide to open / close the outside air introduction port 114 according to the amount of filling. For example, when the filling amount is less than the predetermined amount, the opening control is uniformly performed, and when the filling amount is larger than the predetermined amount, the closing control is uniformly performed.
また、制御部２０１が備えるシステムに設定された穀物の乾燥速度が遅いときは、設定された閾値の温度より低く、穀物の乾燥速度が速いときは、設定された閾値の温度より高くしてもよい。乾燥速度が速いと、穀物から水分の抜けが早くなり、結露しやすいためである。これにより、穀物の乾燥速度に応じて、好適に結露を防止できる。また、制御部２０１は、乾燥速度に応じて外気導入口１１４の開閉を決定してもよい。例えば、設定された穀物の乾燥速度が遅いときは一律に開制御、穀物の乾燥速度が速いときは一律に閉制御するよう構成する。また、張込スイッチ２０２、通風スイッチ２０３、排出スイッチ２０５を操作した場合には、外気導入口１１４を開くことで、漏斗状底板１０８ａに滞留する塵埃を吹き飛ばすことができる。 Further, when the drying rate of the grain set in the system provided in the control unit 201 is slow, the temperature is lower than the set threshold temperature, and when the drying rate of the grain is high, the temperature is higher than the set threshold temperature. Good. This is because when the drying speed is high, water is quickly removed from the grain and dew condensation is likely to occur. Thereby, dew condensation can be suitably prevented depending on the drying speed of the grain. Further, the control unit 201 may decide to open / close the outside air introduction port 114 according to the drying speed. For example, when the set drying rate of the grain is slow, the opening control is uniformly performed, and when the drying rate of the grain is high, the closing control is uniformly performed. Further, when the tension switch 202, the ventilation switch 203, and the discharge switch 205 are operated, the dust accumulated in the funnel-shaped bottom plate 108a can be blown off by opening the outside air introduction port 114.
また、穀物乾燥機１が排風を乾燥部１０２に戻す排風循環構造を備える場合において、制御部２０１は、排風循環率の設定に応じて、排風を多く戻す場合は、一律に外気導入口１１４を閉制御し、少ないときは一律に開制御するように構成してもよい。 Further, when the grain dryer 1 is provided with an exhaust air circulation structure for returning the exhaust air to the drying unit 102, the control unit 201 uniformly returns a large amount of exhaust air according to the setting of the exhaust air circulation rate. The introduction port 114 may be configured to be closed-controlled and uniformly open-controlled when the number is small.
また、穀物乾燥機１の操作盤１０３に設けた静音選択スイッチの操作により、燃焼バーナ１０２ｇの燃焼を夜間の時間帯において、断続燃焼から連続燃焼に切替えるように構成してもよい。例えば、午後１１時から午前６時までは、燃焼制御が２リットル／時の断続運転であれば、２．５リットル／時の連続運転に変更し、１時間乾燥運転し、２時間休止運転とする。これにより、夜間における静音運転が図られる。 Further, the combustion of the combustion burner 102 g may be switched from the intermittent combustion to the continuous combustion in the night time zone by operating the silent selection switch provided on the operation panel 103 of the grain dryer 1. For example, from 11:00 pm to 6:00 am, if the combustion control is intermittent operation of 2 liters / hour, change to continuous operation of 2.5 liters / hour, dry operation for 1 hour, and pause operation for 2 hours. To do. As a result, quiet operation can be achieved at night.
静音選択スイッチが操作された場合において、穀物の張込量が所定以上でない場合は、警告を出したり、乾燥運転を受付けないように構成してもよい。なお、この場合において、張込量の確認ができたら、通常の燃焼量よりも温度低めの設定により、静音乾燥する。加えて、張込量が、設定量以上の場合は、継続乾燥し、張込量が少ない場合は、穀物の拡散音の発生防止のため、休止運転してもよい。加えて、静音選択スイッチが操作された場合において、穀物循環量を昇穀部１０２のエレベータの回転を低下させ、同時に燃焼量を低下させてもよい。これにより静音運転が実現される。 When the silent selection switch is operated, if the amount of grain charged is not more than a predetermined amount, a warning may be issued or the drying operation may not be accepted. In this case, if the filling amount can be confirmed, silent drying is performed by setting the temperature lower than the normal combustion amount. In addition, if the filling amount is equal to or more than the set amount, continuous drying may be performed, and if the filling amount is small, the operation may be suspended in order to prevent the generation of diffusion noise of grains. In addition, when the silent selection switch is operated, the grain circulation amount may be reduced by reducing the rotation of the elevator of the grain raising unit 102, and at the same time, the burning amount may be reduced. As a result, silent operation is realized.
燃焼バーナ１０２ｇが大小２段階の燃焼モードをもつ間欠燃焼式のガンタイプバーナにおいて、高燃焼には入らないことを設定するシステム設定モードを設けることを特徴とした循環式穀物乾燥機において、高燃焼抑制モードにおいては、高燃焼に入らない時間を０〜１２時間を１時間ごとあるいは、任意に設定でき、０を選択した場合には、高燃焼抑制モードに入らず、通常の熱風温度になるように大小切替えて乾燥することができるようにしてもよい。これにより、夜間においては、小燃焼の連続燃焼とすることより、燃焼音を低く抑えることができる。 In an intermittent combustion type gun type burner in which 102 g of a combustion burner has two large and small combustion modes, a high combustion is provided in a circulation type grain dryer characterized by providing a system setting mode for setting not to enter high combustion. In the suppression mode, the time for not entering the high combustion suppression mode can be set every hour or arbitrarily for 0 to 12 hours, and when 0 is selected, the high combustion suppression mode is not entered and the normal hot air temperature is obtained. It may be possible to switch the size to and dry. As a result, at night, the combustion noise can be suppressed to a low level by performing continuous combustion of small combustion.
加えて、穀物乾燥機１の操作盤１０３に設けたタイマスイッチの操作により、タイマ乾燥、休止乾燥、高燃焼抑制乾燥を選択できるようにし、高燃焼抑制乾燥を選択すると、高燃焼抑制モードの時間と、高燃焼抑制監視モードの時間に入るまでの時間を選択できるようにしてもよい。 In addition, by operating the timer switch provided on the operation panel 103 of the grain dryer 1, timer drying, pause drying, and high combustion suppression drying can be selected, and when high combustion suppression drying is selected, the time of the high combustion suppression mode is selected. And, the time until entering the time of the high combustion suppression monitoring mode may be selected.
加えて、燃焼バーナ１０２ｇが大小２段階の燃焼モードをもつ間欠燃焼式のガンタイプバーナにおいて、高燃焼には入らないことを設定するシステム設定モードを設けることを特徴とした循環式穀物乾燥機において、高燃焼抑制モードにおいては、高燃焼に入らない時間を０〜１２時間を１時間ごとあるいは、任意に設定でき、０以外を選択した場合には、タイマの設定をすることで、高燃焼抑制モードに入るまでの時間を任意に設定できるようにしてもよい。これにより、高燃焼に入らないまでの時間をユーザは任意に設定でき、乾燥開始時間がずれても希望する時間になると高燃焼に入らなくなるように作業できる。 In addition, in an intermittent combustion type gun type burner in which 102 g of a combustion burner has a combustion mode of two stages, large and small, in a circulation type grain dryer characterized by providing a system setting mode for setting not to enter high combustion. In the high combustion suppression mode, the time during which high combustion does not occur can be set every hour or arbitrarily for 0 to 12 hours. If a value other than 0 is selected, high combustion suppression can be performed by setting a timer. The time until entering the mode may be arbitrarily set. As a result, the user can arbitrarily set the time until the high combustion does not occur, and even if the drying start time deviates, the work can be performed so that the high combustion does not occur at the desired time.
