Displays the operating procedure and progress. The control procedure is as follows: Step 1 Pay the fee and put the brown rice R into the destoner tank 1. Step 2 The whiteness of the polished rice is displayed by selecting one of "Upper white", "Upper white", and "Seven minutes" using the whiteness selection button. Step 3 Turn ON the start button to start automatic operation. First, the destoner M and the elevator 2 start operating. Step 4 Subsequently, the rotary shutter 7 for the stone excavator is rotated to drop a certain amount of brown rice R from the stone excavator tank 1 into the sorting wire net 4. The supply speed of the brown rice R can be adjusted by changing the rotation speed of the stone cutter rotary shutter 7. Step 5 The brown rice R that has fallen into the sorting wire net 4 removes stones and other foreign matter by swinging the sorting wire mesh 4 and blowing by the windmill 8, and falls from the brown rice outlet 10 to the lower receiving port 22 of the elevator 2, and the lift 2 To put it into the rice polishing tank 3 of the rice polishing machine N. Step 6 When the tank lower limit switch 24 is turned ON by the brown rice R put into the rice polishing tank 3, the rice polishing machine N
Operation starts. Step 7 When the milled rice tank 3 is full of brown rice, the tank upper limit switch 25 is operated to stop the stone mill rotary shutter 7 to stop the flow of the brown rice into the stone mill M, and to prevent the brown rice from overflowing from the milled rice tank 3. prevent.

ランプの点灯を確認して、精米機Nを停止し終了する。Step 10 In this state, after about 10 seconds have elapsed, the rice return damper 30 is closed by the open / close motor 33,
The polished rice is discharged outside the machine through the rice return damper 30 and stored in the white rice storage box 32 outside the machine. Step 11 15 after turning on the start button
After a lapse of more than a second, the tank lower limit switch 24 of the rice polishing tank 3
When is turned "OFF", the process proceeds to residual rice processing. Step 12 The destoner rotary shutter 7 is stopped, the subsequent introduction of brown rice R is stopped, and the operation of the destoner M is continued. Step 13 The rice mill N, the suction fan 26 and the pressure feeding fan 28 are stopped, and the rice return damper 30 is
open. Step 14 The operation of the stone crusher M is continued, and the stone discharge shutter 13 is opened for about 3 seconds.
The remaining stones are collected in the stone receiving box 16 through the stone outlet 15 from the stone outlet 14 and the stone outlet shutter 13 is closed. Even if the destoner tank 1 is emptied and the supply of the brown rice R is completed, the brown rice R and the stone grains remain on the sorting wire net 4 for almost 70% of the net area. Step 15 The remaining rice discharging shutter 21 is opened for about 30 seconds, the brown rice R remaining on the sorting wire net 4 is transferred to the remaining rice discharging wire mesh 17, and falls from the brown rice discharging port 10 to the lower receiving port 22 of the elevator 2 to discharge the remaining rice. The shutter 21 is closed, the stone discharge shutter 13 is opened again for 3 seconds, and the remaining stone is discharged. After that, the stone removing machine M is stopped. Step 16 Next, the rice mill N is operated for about 15 seconds,
The white rice in the middle is returned to the rice polishing tank 3 through the rice return damper 30, the rice return chute 34, and the elevator 2. Step 17 Next, the liner 50 is moved in the direction B by the whiteness adjusting motor 49, and the main resistance support rod 45 is rotated about the fulcrum shaft 46 by the remaining rice discharging metal fitting 51 to open the resistance plate 29. At the same time, the rice return damper 30 is closed by the open / close motor 33. The rice polishing machine N is operated for about 10 seconds, and the remaining rice is discharged from the white rice discharge port 31 to the outside and collected in the white rice storage box 32. Step 18 Further, in this state, the whitening roll 35 is
Rotating for 2 seconds and stopping for 1 to 2 seconds are repeated two or three times, and at the same time, air is blown out between the whitening roll 35 and the whitening cylinder 36 by the pressure-feeding fan 28, and the remaining rice remaining in the air outlet 41 is completely discharged. Step 19 The pumping fan 28 and the rice mill N are stopped.
Next, the liner 50 is returned to the direction A by the gear motor 49 to adjust the whiteness of the polished rice to "upper white", and the lighting of the upper white lamp provided on the control panel is confirmed.

る。As described above, in the present invention, semi-milled rice generated at the start of milling and residual rice remaining in the milling machine N at the end of milling are removed by the milling damper 30 through the milling chute 34 and the elevator 2. By returning to the rice polishing tank 3 and circulating again, it is possible to finish the rice with a predetermined whiteness from the beginning to the end. Further, by adjusting the pressing force of the resistance spring 47 of the resistance plate 29 by the gear motor 49 and the linear 50, a predetermined whiteness of the polished rice can be easily set, and the polished white rice having a stable polished whiteness can be discharged. Further, by providing an air blowing outlet 41 to the milling roll 35 of the milling machine N to blow air into the milling chamber 52 and intermittently rotating the milling roll 35 at regular intervals, the remaining rice can be discharged without leaving. In addition, a destoner rotary shutter 7 is provided at the bottom of the destoner tank 1 of the destoner M, and a certain amount of the introduced brown rice R is taken into the destoner M irrespective of its wetness and dryness. You can mill rice.
