CONSTITUTION:Drying operation is carried out under a specified temperature drying mode in which hot air temperature generated from a hot air device 4 is controlled so as to perform a drying operation while some crop particles are fed out and being flowed down from a crop particle storing chamber 8 toward a crop particle drying chamber 9, a temperature controlling and drying mode in which drying operation is carried out whole the hot air temperature is being changed and controlled and a drying stopped mode in which a drying operation and a stopped state are repeatedly controlled. In the case that a surrounding air temperature sensor 49 and a discharged air temperature sensor 14 show a slight trouble during crop particle drying operation and a degree of trouble is slight, the hot air temperature is changed and controlled to a lower temperature by a predetermined value, the drying mode is changed and controlled to a drying mode of the specified temperature and the crop particle drying operation is continued. With such an arrangement, no sweaty state occurs in the crop particles and it is possible to prevent quality of crop particles from being reduced.

Drying is performed in a constant temperature drying mode, in which the hot air temperature is changed and controlled, a temperature control drying mode in which air is blown into the drying chamber 9 for drying, and a pause drying mode in which drying and pausing are repeatedly controlled. In the grain dryer, the abnormality content that has occurred during grain drying detects an outside air temperature 49 and an exhaust temperature sensor 14 that detects an exhaust temperature.
When the problem is minor and the content of the problem is mild and the drying operation can be continued, after the problem occurs, the hot air temperature at that time is changed to a predetermined low temperature and the drying mode is changed to the constant temperature drying mode. A grain drying control method characterized by continuously controlling grain drying.
