The change in the calculated humidity difference is compared with the change in the humidity difference stored in the setting memory of this CPU 45, and drying control is performed while monitoring these alternately.During this drying control, the change in the detected grain moisture value and the calculated humidity are compared. If an abnormal value is detected in either one of the changes in the difference, it is detected that a malfunction has occurred, and when this abnormal value is detected in one, the dryer 8 is operated in the same way as above when the other normal value is detected. It is configured to automatically stop each part.

湿度差は14%であると記憶させた構成である。Additionally, the drying control device 47 has the following functions. That is, the CPU 45 calculates the humidity between the hot air humidity in the ventilation chamber 4 and the exhaust air humidity in the ventilation chamber 5 when grains are finished, depending on the initial moisture content of the grains and the target finishing moisture content. This is a configuration in which a difference is set and stored. For example, if the initial moisture content is 25% and the target finished moisture content is 15%, the humidity difference between the hot air humidity and the exhaust air humidity is 14%. .
