出動作は停止する。As the whitening action progresses and the whitening pressure in the circulation circuit decreases,
The current value of the main motor decreases, and the input voltage to the comparator circuit also decreases. In this way, when the input voltage supplied to the comparator circuit drops below the lower limit of the reference voltage la preset to the comparator circuit, the signal is sent to the drive circuit to rotate the auxiliary motor, thereby A resistor attached to the wall of the circulation circuit of the rice milling machine is gradually protruded into the vertical circulation circuit to increase the milling pressure.The milling pressure increases, the 'ifA value of the main motor increases, and the input voltage to the comparison circuit increases. When the voltage increases and reaches the set reference voltage range, the signal inputted from the comparator circuit to the drive circuit stops being sent, and the above-described projecting operation of the resistor stops.
