出し流下させる制御方式であった。Conventional technology Conventionally, grains stored in a storage chamber are dried by rotating a delivery valve and causing the grains to flow down the drying chamber below the storage chamber. The control system was such that the grains were fed out of the drying chamber and flowed down at a constant rotation until the end of the drying process.

内に穀粒の乾燥が終了しないことがある。Problems to be Solved by the Invention The grains are fed out from the upper storage chamber into the drying chamber by a constant rotation of the valve, and are allowed to flow down, while the hot air generated by the burner is sucked by the exhaust fan, thereby drying the grains from the hot air chamber. In the grain feeding method of the dryer, in which the room is ventilated, the air is sucked and exhausted by the exhaust fan through the ventilation chamber, and the grains flowing down the drying chamber are exposed to this hot air and dried. When the grains to be stored and dried have a high moisture content, the temperature of the grains increases slowly at the beginning of drying.
For this reason, the drying loss rate of the grains in the initial stage of drying becomes particularly poor, and the overall drying efficiency until the end of drying also decreases, so that drying of the grains may not be completed within a predetermined time.

2) The grains flowing down inside are exposed to this hot air and dried, and when the moisture content of the grains reaches the specified moisture content, the control device automatically controls the dryer to automatically stop the dryer. The rotation of the feed valve (3) is controlled by the control device by a predetermined amount d, so that the flow rate of the grains flowing down in the drying chamber (2) is slowed down, and the flow rate of the grains flowing down in the drying chamber (2) is reduced. The grains flowing down the drying chamber (2) are exposed to the hot air for a long time and are dried.

The rest is controlled by the control device so that the drying speed is a predetermined amount faster, so the time of exposure to the hot air generated by the burner (4) differs, so even when drying grains with high moisture content, the initial drying speed is These high-moisture grains are exposed to the hot air generated by the burner for a long time while flowing down the drying chamber (2), and the temperature of the grains increases, resulting in high grain temperature and drying. The drying rate of the grains is improved at the initial stage, and the overall drying efficiency until the end of drying is improved, so that the drying of the grains is completed within a predetermined time, and the temperature of the hot air generated from the burner (4) is increased. Since this method does not improve drying efficiency by drying, grains may be placed on the body side,
It also does not become crushed.

The rotation of the solenoid (3) is controlled to be slow, so that the speed of the grains flowing down in the drying chamber (2) is slowed down, and the grains are dried.After a predetermined period of time, the control device (43) 30)
is operated to quickly control the rotation of the delivery valve (3), thereby increasing the flow rate of the grains flowing down in the drying chamber (2) and drying the grains.

。The grains housed and dried in the plate wall (9) flow slowly down the drying chamber (2) for a predetermined period of time from the start of drying, and quickly flow down the drying chamber (2) after the predetermined period of time has elapsed. By this,
Even when drying grains with high moisture content, the time of exposure to the hot air generated from the burner (4) increases in the early stage of drying, and the temperature of the grains to be dried rises, causing the grains to become hot. As a result, the drying rate of grains decreases even in the early stages of drying.
