PURPOSE:To prevent erroneous manipulation and the erroneous operation of automatic drying control, by displaying a corrected moisture value when the moisture value of grain is corrected while performing error display when correcting manipulation is performed to a different kind of grain erroneously. CONSTITUTION:When the correction value in a grain correcting circuit 4 is altered, the position of a rotary switch SW1 is stored in the memory AM of a microcomputer 5 and quality is stored in memory BM. In this case, the quality signal is compared with the signal stored in memory BS and, if both of them are coincided, grain is judged as the same kind and digital display is performed by a display device 6. In addition, when the signals of the memory BM and the memory BS are not coincided, grain is judged as a different kind and an error mark is displayed by the display device 6. By this method, erroneous manipulation and the erroneous operation of automatic drying control can be prevented. |
