It communicates with the level sensor 28 via the arithmetic and control unit 13 so that the display blinks at the time.

Next, the operation of the above embodiment will be explained.

First, a desired brand and weight are selected using the operation panel 14. For example, Koshihikari 18! J + Nihonbare 12K
When the IJ and = keys are input, the amount is calculated by the arithmetic and control unit 13 and displayed on the amount display 25. Then, the face value of the coin (magnetic card etc. may be used in some cases) inserted from the coin slot 29 is detected by the coin reader 26.
When the confirmation process is performed, the rotary valves VT and V3 of tank T1 where Koshihikari is stored and tank T3 where Nihonbare is stored are turned on, and 18 KO Sasanishiki comes from rotary valve ■1, and from rotary valve ■3. Two 12KQ units rotate each to eject.

That is, if the rotary valve is capable of discharging 1 kg per rotation, the valve (1) is driven 18 times, and the valve (3) is driven 12 times. The weight of each brand of rice discharged per rotation of the rotary valves (1) to (V4) is stored in the memory 27.

In this way, the brown rice that has fallen into the hopper 2 is returned to the hopper 2 via the chute pipe 5 by the circulation elevator 10, which starts operating at the same time as any of the rotary valves V1 to V4 is activated. At this time, the circulation elevator 1
Since the discharge part of 0 is short and has a large discharge port, the brown rice returned to the hopper 2 is discharged while scattering in all directions, and stirring and mixing of different kinds of brown rice is promoted. Shoot pipe 5. After the circulation stroke by the circulation elevator 10 continues for a certain period of time, for example, 5 minutes, the timer causes the motor M8 that operates the first switching valve 4 to turn ON, so that the switching valve 4 closes the flow path to the chute pipe 5. The brown rice in the hopper 2 flows down to the milling chamber supply port of the rice milling machine 3 and is subjected to the milling action. The motor M5 of the rice milling machine 3 is turned on when the motor M8 is turned on so that the first switching valve 4 operates toward the chute pipe 5 side.
At the same time, the motor M9 starts driving, and at the same time, the motor M9 that operates the second switching valve 9 operates in the direction of closing the chute pipe 8 on the ONL and discharge side. The second switching valve 9 is operated by a timer to close the chute pipe 7 on the circulation side again after a certain period of time, for example, 10 seconds, and during this time, the polished rice (
Those that have not been completely milled are returned to the hopper 2 via the chute pipe 7 and the circulation elevator 10 to be re-milled. When the second switching valve 9 operates again in the direction of closing the chute pipe 7, the polished rice discharged from the rice milling machine 3 flows into the milled rice receiving trough 6. Shoot pipe 8. The rice is temporarily stored in the rice milling tank 12 via the discharge elevator 11 (which starts operating at the same time as the rice milling machine 3).

In this way, rice milling by the rice milling machine 3 continues, and when the brown rice in the hopper 2 is almost gone and the level sensor 28 detects the "empty state", the second switching valve 9 is activated for an appropriate time as in the beginning of the operation of the rice milling el13. For example, the direction is changed to close the chute pipe 8 on the discharge side for 10 seconds, and then the direction is changed again to close the chute pipe 7 on the circulation side.

Therefore, a part of the polished rice discharged from the rice milling machine 3 passes through the chute pipe 7 and the circulation lift 1110 and is discharged onto the slightly remaining brown rice in the hopper 2, so that the polished rice is completely removed from the polished rice 113 until the end. The milled rice can be discharged.

After the level sensor 28 detects the "empty state", the brown rice remaining in the hopper 2 and the circulated polished rice are completely introduced into the rice polishing tank 12, and the rice is discharged after a period of time, for example, 3 minutes has elapsed. The lamp of button 31 starts blinking, indicating that the polished rice is ready to be discharged. At this time, the lamp of the ejection button 31 and a buzzer may be used together. When the discharge button 31 is pressed, the motor Ml that operates the shutter 12B of the polished rice discharge port 12A is driven to discharge the polished rice into a bag or the like.

When the rice milling tank 12 is full, the shutter 12B closes again after a period of time, for example, 2 minutes, during which the milled rice in the tank can be completely discharged. Circulation lift8. A motor M5 that drives the discharge elevator 11. M.S.
After M7 stops and the first switching valve 4 operates in the direction of closing the grain feeding path on the rice milling machine 3 side, the entire process ends.

Effects of the Invention As described above, in the present invention, when the desired raw material brown rice and its weight are input from the operation panel, the quantitative discharge device provided on the discharge side of each brown rice tank is driven by the arithmetic and control device, and the input brown rice is In addition to discharging only the weight of brown rice into the hopper, a circulation path is formed via a switching valve in the pre-process of the rice milling machine to mix and stir the brown rice, so you can freely select the desired blended rice, and you can You can always get the amount of freshly polished rice you need.
