The required dry dry fuel consumption is stored, and the dry target moisture is determined from the tension moisture value corresponding to the set drying speed, the amount of stretched grain, and the detected outside air temperature based on the standard dry fuel consumption by a predetermined calculation formula. The dry fuel consumption required for drying up to the value is calculated, then the remaining amount of fuel in the fuel tank 21 at the end of the drying operation is calculated and displayed on the display device 32 of the operation panel 31. If there is a possibility of running out of fuel, a display warning is given to the display device 32 of the operation panel 31.

The fuel consumption is calculated while correcting the reference dry fuel consumption according to the calculation formula in consideration of the unit fuel consumption for each unit, and each reference fuel consumption up to the dry target moisture value is sequentially displayed on the display device 32.

It is possible to accurately grasp the necessity of adding fuel to 21.

また、表示装置３２に燃料消費量を算出し表示するにあたり、オペレータの設定可能な乾燥速度、すなわち、高速乾燥，迅速乾燥，普通乾燥，低速乾燥における予測乾燥時間，所定水分値減少に要する基準燃料消費量，乾燥作業終了までの必要燃料消費量を合わせて表示するようにすると、オペレータの省エネ乾燥運転の選択の利便性を高めることができる。 Further, when calculating and displaying the fuel consumption amount on the display device 32, the drying speed that can be set by the operator, that is, the predicted drying time in the high speed drying, the quick drying, the normal drying, the low speed drying, and the reference fuel required for reducing the predetermined moisture value. If the consumption amount and the required fuel consumption amount until the completion of the drying operation are displayed together, the convenience of the operator in selecting the energy saving drying operation can be improved.

また、燃料消費により燃料が減少したときには、図５（Ｂ）に示すように、燃料減少状態を各ゲージブロックに減少量に応じて無段階に色彩変更しながら減少表示し、各ゲージブロックの表示を一括変更表示しないので正確な燃料残量を表示するようにしている。 When the fuel is reduced due to fuel consumption, as shown in FIG. 5 (B), the fuel reduction state is displayed on each gauge block with a stepless color change according to the amount of reduction. Since the change is not displayed at once, the correct remaining fuel amount is displayed.

前記構成によると、燃料ゲージ３７の燃料残量を操作盤３１の表示装置３２に簡単に入力表示することができ、夜間で乾燥施設が暗いときにも操作盤３１の表示装置３２の燃料残量表示から燃料残量を容易に把握することができる。 According to the above configuration, the fuel remaining amount of the fuel gauge 37 can be easily input and displayed on the display device 32 of the operation panel 31, and the fuel remaining amount of the display device 32 of the operation panel 31 can be obtained even when the dry facility is dark at night.

Thus, when fuel is supplied to the fuel tank 21, the reset function is activated, and the actual fuel consumption amount calculated by subtracting the accumulated fuel supply amount from the entire tank capacity is calculated. The fuel consumption of the drying operation is sequentially calculated, and the fuel consumption from the start of the drying operation to the end of the drying operation is calculated and displayed according to the actual fuel consumption.

For error records stored in non-volatile memory, the type of error that occurred is checked against the past record error type, and if it is not the same type of error, it is stored as a newly generated error type. In the case of the same type of error as the recording error, add the number of times to the end of the error that occurred in the past and store it, reduce the memory load, store a lot of defect data, and grasp the whole picture Yes.
