(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. Therefore, when the minute ti 429 is moved to the outer end side of the protrusion rod n, the protrusion rod 28 moves downward, and the outflow amount regulating valve U moves upward to reduce the amount of water falling from the outflow port 19. do. Along with this,
The rod 31, the screw punch A, the turnbuckle 36, the screw punch π, and the rod 38 move downward, rotate the rotary rod 41 around the shaft 40, and pull up the inflow amount control valve 44. Therefore, when the inlet 15 is opened and the weight 4, which feeds a large amount of grain into the inside 24 and into the rice milling chamber 9 and mills a large amount under high pressure, is brought to 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 remove the M2O, the bolt 25 will come off.
25 is exposed, the bran removing cylinder 14 is removed, and the bran removing cylinder 14 is replaced with a new one.

(Effects) As described above, the conventional circulation rice mill has a through hole F in the front and back direction in the circulation tank E, and a horizontal grain feeding spiral A in the lower part of the through hole F, as shown in FIG. is installed horizontally, a bran removing cylinder B is installed at the bottom of the horizontal grain feeding spiral A, a resistance valve is attached to the pressure chamber C at the tip of the horizontal grain feeding spiral A, and the rice is circulated as shown by the arrow to remove the bran. While doing so, it is possible to perform circulatory ejaculation (#Publication No. 36-1118). However, the known ones are
The degree of circulation and pumping can only be adjusted by the resistance of the resistance valve, and the flow rate is not adjusted, so strong pressure pumping is not possible.

However, in the present invention, a downward feeding grain spiral 7 and a vertically rotating milling roll 4 are provided in the circulation tank 5, and the outer periphery of the downward feeding grain spiral 7 is connected to the outer periphery of the vertically rotating milling roll 4 by a grain feeding cylinder 13. is surrounded by a bran removing cylinder 14, an inlet 15 is formed at the upper end of the grain feeding cylinder 13, and an outlet 19 is formed at the lower end of the bran removing cylinder 14, and the material discharged from the outlet 19 is passed through the circulation ascending path 18. In the case where the flow rises and flows into the inflow port 15, the outflow port 19 is provided with an outflow amount regulating valve 3 for adjusting the outflow amount.
4, and the inflow port 15 is provided with an inflow control valve 44 for adjusting the inflow, and the outflow control valve 44 is connected to the inflow control valve 44 when the outflow control valve 44 is closed. 4
4 is a pressurizing device in a circulating rice mill that is connected so that when the outflow control valve 44 opens, the inflow control valve 44 closes. Therefore, only by adjusting the outflow control valve U, high-pressure milling can be achieved. It has the effect of freeing both gentle pressure and ejaculation.
