知られている。 A conventional automatic control device for derolling is a device that senses changes in the load of the electric motor during operation and adjusts the derolling gap to an appropriate value in response to fluctuations in the motor load, which decreases as the derolling wears out. Special Public Service 1977
It is known from Japanese Patent Publication No.-31144, Japanese Patent Publication No. 51-1620, etc.

多くする等の問題点があつた。 In the technologies described in each of the above publications, the derolling gap is not set to a predetermined gap at the start of the automatic operation of the dehuller, and when paddy is supplied to the deroller by opening the shutter, the electric motor is turned off. As the load fluctuates, the derolling gap will be corrected, but before the appropriate load value is reached, rice that has not reached the specified derolling rate may flow out, or rice derolling with too small a derolling gap may occur. This may result in surface sliding and crushed particles, and in the case where the roll gap is manually operated, there are problems such as the need for manpower to adjust the roll clearance to a predetermined level and the loss of time. It was hot.
