Problems to be Solved by the Invention While the grains housed in the storage chamber are flowing down from the storage chamber into the drying chamber, hot air generated from the burner is passed from the hot air chamber to the drying chamber, passes through the exhaust chamber, and is sent to the exhaust fan. The grains are repeatedly dried by being exposed to the hot air, which is sucked and exhausted by air, and the grains are dried.The moisture value of the grains during drying is detected by a moisture sensor that operates at predetermined time intervals. In a dryer that stops drying grains when this moisture sensor detects a grain moisture value that is the same as the finishing target moisture value, if the outside air humidity at the end of drying is high, dried grains The moisture content of the grains may absorb moisture and become higher than the target finishing moisture value. If you do the hulling operation without noticing this high moisture value, the moisture value of the grains may exceed the specified moisture value. As a result, the grade of the grains may be lowered or they may not be able to be delivered.
