Description
【発明の詳細な説明】 この発明は、乾燥機の乾燥制御装置に関する。[Detailed description of the invention] The present invention relates to a drying control device for a dryer.
従来の穀物乾燥機の乾燥制御は、水分計とタイマーとを
用い、水分計による穀物の含水率が所定値になるか最初
に設定したタイマーの予定乾燥時間が満了するかのいず
れかの信号により、乾燥機の乾燥作業を停止することに
よって行なわれていた。Conventional grain dryer drying control uses a moisture meter and a timer, and is controlled by a signal that either the moisture content of the grain reaches a predetermined value by the moisture meter or the scheduled drying time set by the timer has expired. This was done by stopping the drying operation of the dryer.
そして、このタイマーによる予定乾燥時間の設定は、す
べて作業者が穀物の初期水分値および穀物の量から乾燥
温度を設定し、その温度によって通常の乾燥が行なわれ
るものとして算出されていた。The scheduled drying time set by this timer is calculated based on the assumption that the operator sets the drying temperature from the initial moisture value of the grain and the amount of grain, and that normal drying is performed at that temperature.
ところが実際の乾燥作業においては、被乾燥物の種類や
夾雑物の量等によって、予定乾燥時間を経過後必ずしも
所望の含水率の穀物が得られず、また、乾燥湿度は終始
一定であって、乾燥速度も一定であり、設定温度を高く
すると乾燥能率は向上するが、乾燥後期になり含水率が
減少してくると籾にひびが入る胴割れ現象が生じて品質
を悪イリせ、設定温度を低くすると胴割れ現象はなくな
るが、乾燥能率が著しく低下するという欠点があった。However, in actual drying operations, depending on the type of material to be dried and the amount of contaminants, it is not always possible to obtain grains with the desired moisture content after the scheduled drying time, and the drying humidity remains constant throughout. The drying speed is also constant, and increasing the set temperature improves the drying efficiency, but as the moisture content decreases in the later stages of drying, cracks occur in the paddy, resulting in poor quality. When the temperature is lowered, the cracking phenomenon disappears, but there is a drawback that the drying efficiency is significantly reduced.
本発明は、上述の欠点を除去し、穀物の乾燥状態に応じ
て乾燥速度を変化させることにより胴割れ、過乾燥など
をなくし、乾物の種類や夾雑物の量に影響されずに所望
の含水率の穀物が得られるようにした乾燥機の乾燥制御
装置を°提供することを目的とするものである。The present invention eliminates the above-mentioned drawbacks, eliminates shell cracking, overdrying, etc. by changing the drying speed according to the drying state of the grain, and achieves the desired moisture content without being affected by the type of dry matter or the amount of impurities. It is an object of the present invention to provide a drying control device for a dryer that enables grains to be obtained at a uniform drying rate.
本発明の実施例を図面を参照して説明する。Embodiments of the present invention will be described with reference to the drawings.
ｌは張込セ、ンサで乾燥機に取付けられ、穀物の張込量
を検知する。２は水分センサで同じく乾燥機に取付けら
れ穀物の含水率を検知する。1 is attached to the dryer with a tensioning sensor, which detects the amount of grain being loaded. 2 is a moisture sensor which is also attached to the dryer and detects the moisture content of the grain.

御部４は、乾燥機排出バルブ５および燃料パルプ６に連
絡している。3 is a thermometer, which is installed outside the wall of the dryer and inside the dryer to measure the outside air temperature and the temperature inside the dryer. 4H drying control unit, which is connected to the tensioning sensor IK) and sets the dryer discharge valve rotation speed according to the output from the tensioning sensor 1; A reference temperature setting device that sets a reference drying temperature according to the output from the sensor 1, a drying speed setting device that is connected to the moisture sensor 2 and sets the drying speed based on the output from the moisture sensor 2, and a drying speed setting device that sets the drying speed according to the output from the moisture sensor 2. It has a temperature correction device etc. that corrects the reference temperature. Furthermore, the drying control 4 is in communication with the dryer discharge valve 5 and the fuel pulp 6.
次に、その作用を説明する。Next, its effect will be explained.
乾燥機への穀物の張込み作業が終了すると、張込センサ
１からの信号により乾燥制御部４に内蔵されている・９
ルブ回転数設定装置５が作動して乾燥機排出バルブ５の
回転数が設定され、該回転数でバルブ５が回転される。When the work of loading grain into the dryer is completed, a signal from the loading sensor 1 causes the drying controller 4 to have a built-in controller 9.
The valve rotation speed setting device 5 operates to set the rotation speed of the dryer discharge valve 5, and the valve 5 is rotated at the set rotation speed.
更に、同じく張込センサ１の信号により基準温度設定装
置により基準温度が設定される。Furthermore, a reference temperature is set by a reference temperature setting device based on a signal from the filling sensor 1 as well.
乾燥機の乾燥速度は穀粒の含水率が２１％以上の場合は
１時間当り０．９％ずつ乾燥し、２１％未満の場合は１
時間当り０．７％ずつ乾燥するように設定される。The drying speed of the dryer is 0.9% per hour if the moisture content of the grain is 21% or more, and 1 hour if the moisture content of the grain is less than 21%.
It is set to dry by 0.7% per hour.

乾燥制御部４から燃料バルブ６に信号を発し油量を調整
することにより行なわれる。This is done by operating the drying speed setting device, temperature correction device, etc. in the drying control section 4 in response to a signal from the moisture sensor 2, and correcting the drying speed and temperature according to the change in the drying state, that is, the moisture content. . Correct the temperature,
This is done by sending a signal from the drying control section 4 to the fuel valve 6 to adjust the oil amount.
なお、穀物の含水量が１８％以上の場合は、３０分毎に
水分センサ２の計測を行ない、乾燥終了状態に近い１８
％を過ぎてからＦｉ４分毎に計測を行なうことにより過
乾燥を防止する。If the moisture content of the grain is 18% or more, the moisture sensor 2 will measure it every 30 minutes, and the moisture content will be measured every 30 minutes.
%, over-drying can be prevented by measuring every 4 minutes.

きる。As described above, according to the present invention, the initial setting of the rotation speed and temperature of the dryer is performed by the tension sensor,
Since the moisture sensor corrects and sets the drying rate or temperature at any time during the drying operation, drying efficiency is good and high quality rice can be obtained without cracking or overdrying of the dried material.
