PURPOSE:To detect an over-current of each of feeding device and a discharging device with one over-current sensing device by a method wherein the feeding device and the discharging device are removably and separately connected to output terminals of an operating device and a connected power supply circuit is provided with the over-current sensing device for sensing an over-current between the feeding device and the discharging device. CONSTITUTION:An operating device 3 for starting and stopping a drying machine is provide. A feeding device 5 for feeding grain to a drying machine and a discharging device 6 for receiving the dried grain and discharging them out of the machine are connected separately and removably to output terminals of the operating device 3A connection power supply circuit 7 is provided with an over-current sensing device 8 for sensing an over-current between the feeding device 5 and the discharging device 6. The over-current sensing device 8 is provided in the connection power supply circuit 7 for the output terminals 4 of the operating device 3, thereby the over-current at the feeding device 5 and the discharging device 6 can be detected by one over-current sensing device 8, resulting in that a substantial cost reduction can be attained. Separate sensing of the over-load of these feeding device 5 and the discharging device 6 prevent trouble from occurring.
