(effect) Next, we will discuss the effect.

When brown rice is put into the circulation tank 5 and the motor 2 is energized to rotate the vertical axis rice milling roll 4 and the downward feeding grain spiral 7, the grains in the circulation tank 5 flow through the inlet 15 and are downwardly fed. The rotation of the spiral 7 sends it downward. The rice then flows into the rice polishing chamber 9, flows downward through the outflow port 19, rises within the circulation chamber 18, and then flows in through the inflow port 15 again, repeating the cycle. In this case, at which point is the pressure highest? Since the outlet 19 is formed narrower than the rice polishing chamber 9, the pressure inside the rice polishing chamber 9 is highest. That is, in the rice polishing chamber 9, the bran is removed to the maximum extent, and the removed rice passes through the holes of the bran removal tube 14, flows into the through hole 16, is sucked by the suction fan 20, and enters the bran removal chamber 21. It is stored.

When the weight 29 is moved to the outer end side of the protrusion rod 28, the protrusion rod 28 moves downward, and the outflow control valve 34
moves upward to reduce the amount of water falling from the outlet 19. Accordingly, the rod 31, the screw rod 35, the turnbuckle 36, the screw rod 37, and the rod 38 move downward, causing the rotary rod 41 to rotate about the shaft 40, and the inflow amount regulating valve 44 to be pulled up. Therefore, the inlet 15 is opened, and a large amount of grain is sent into the inside 24 and into the rice milling chamber 9, and a large amount of grain is milled under strong pressure. When the weight 29 is moved toward the inner end, the above is reversed.

However, as the polishing progresses, the bran removing cylinder 14 wears out and must be replaced. In that case, loosen the bolt 27, the lid 26 will come off, and the lid 26 will come off.
When the bolt 25 is removed, the bolt 25 is exposed, so the bolt 25 is removed, the bran removing cylinder 14 is removed, and the bran removing cylinder 14 is replaced with a new one.

(Effects) As mentioned above, the conventional circulating rice mill
As shown in the figure, a through hole F in the front and back direction is formed in the circulation tank E, a horizontal grain feeding spiral A is installed horizontally at the bottom of the through hole F, and a bran removing cylinder B is installed at the bottom of the horizontal grain feeding spiral A. A resistance valve D is provided in the pressure chamber C at the tip of the horizontal grain feeding spiral A.
It is possible to remove the rice bran by circulating it in the direction of the arrow as shown in the arrow.
Publication No. 1118). However, in the above-mentioned known method, the degree of circulation and ejaculation can only be adjusted by the resistance of the resistance valve D, and the flow rate is not adjusted, so that strong pressure ejaculation cannot be performed.

However, in the present invention, a downward feeding grain spiral 7 and a hard-shaft rotating whitening roll 4 are provided in the circulation tank 5, and the outer periphery of the downward feeding grain feeding spiral 7 is connected to the outer periphery of the hard-shaft rotating whitening roll 4 using a grain feeding tube 13. is surrounded by a bran removing cylinder 14, and an inlet 15 is connected to the upper end of the grain feeding cylinder 13.
An outlet 19 is formed at the lower end of each of the outlet ports 19 and the discharged from the outlet 19 ascends the circulation ascending passage 18 and flows into the inlet 15. The inflow port 15 is provided with an inflow control valve 44 to control the inflow, and the outflow control valve 34 and the inflow control valve 44 are connected to each other. The inflow control valve 44 opens when the outflow control valve 34 is closed, and the inflow control valve 44 closes when the outflow control valve 34 opens.The inflow control valve 44 is used as a pressurizing device in a circulating rice mill, and therefore the outflow control valve 34 cannot be adjusted. It has the effect of allowing you to freely perform both strong pressure and low pressure semen.
