It is formed to prevent it from coming off.

The lower end 19 of the vertically sliding grain feeding cylinder 17 faces the lower end of the downward feeding grain feeding spiral 5, but the vertically sliding grain feeding cylinder 1
7 itself moves up and down, the lower end 19 is structured to slide up and down centering on the lower end of the downward feeding spiral 5.

A bran removing cylinder 20 is provided at the lower end 19 of the vertically sliding grain feeding cylinder 17.
Connect the top ends of. A whitening chamber 21 is formed between the outer peripheral surface of the whitening roll 6 and the inner surface of the bran removing cylinder 20.

When rice grains are pushed into the milling chamber 21 by the action of the downward feeding spiral 5, the pressure within the milling chamber 21 increases, and the funnel portion 33 tends to descend under the pressure.

are screwed together.

That is, when the turnbuckle 63 is rotated, the shaft 5
7 and the shaft 61 is adjusted.

In addition, 64 is a rice bran chamber, and 65 is a circulation ascending path.

(effect) Next, we will discuss the effect.

(When the weight 44 is adjusted inward) When the weight 44 is adjusted to the innermost position, the lever 40
The force for moving the elongated hole 41 upward becomes the minimum, and therefore the vertical sliding grain feeding cylinder 17, the bran removal cylinder 20, and the vertical adjustment cylinder 32 all descend, and the space between the tapered part 23 and the funnel part 33 is lowered. The formed outlet 45 opens to the maximum,
The lower rod 60, which is pivotally attached to the upper end 18 of the vertically sliding grain feeding cylinder 17 through a shaft 61, is moved downward, and the lower screw 6
2. Lower the elongated hole 55 of the vertical movement lever 54 to the maximum via the turnbuckle 63, upper screw 59, upper rod 58, and shaft 57. Therefore, the lower end 51 of the vertical adjustment body 50 approaches the hopper portion 14 to the maximum, thereby making the inlet 15 narrowest.

That is, the inlet 15 is adjusted to be narrow and the outlet 45 is adjusted to be wide. In this state, brown rice is put into the circulation tank 8, and when the motor 2 is energized and the rotating shaft 4 is rotated, the downward feeding grain feeding spiral 5 fixed to the outer periphery of the rotating shaft 4 and the milling roll 6 rotate together. However, the small amount of grain that has flowed in from the inlet 15 is sent downward by the rotation of the downward feeding grain feeding spiral 5 to send the brown rice filling the grain feeding chamber 11 downward into the brown rice group filling the milling chamber 21. On the other hand, the pressure inside the whitening chamber 21 is further increased slightly. When the whitening roll 6 rotates in this state, the stirring ridges 7 formed on the outer periphery of the whitening roll 6
The rice grains are stirred, and the bran on the surface of the rice grains is peeled off and discharged from the bran removing cylinder 20 into the bran chamber 64, which is sucked by the rotation of the bran suction fan 27 located below and stored in the bran box 30.

Thus, the downward feeding grain spiral 5 continues to rotate and feeds the grains one after another into the milling chamber 21, so that the grains are polished in the milling chamber 21, descend through the outlet 45, and pass through the ascending path 65. It circulates and creates circulation. The grain thus ascends through the ascending passage 65 and flows into the grain feeding chamber 11 through the inlet 15, but as mentioned above, the vertical adjustment body 50 is lowered, and a narrow gap is opened between the hopper portion 14 and the lower end 51. Since the amount of grain flowing into the grain feeding chamber 11 is small, the pressure inside the milling chamber 21 is low and low-pressure milling is possible.

(When the weight 44 is adjusted outward) When the weight 44 is adjusted to the outermost position, the lever 40
The force for moving the elongated hole 41 upward becomes maximum, and therefore, the vertical sliding grain feeding cylinder 17, the bran removal cylinder 20, and the vertical adjustment cylinder 32 all rise, and the space between the tapered part 23 and the funnel part 33 increases. The outlet 45 formed is closed to a minimum,
The lower rod 60, which is pivoted to the upper end 18 of the vertically sliding grain feeding cylinder 17 by a shaft 61, is moved upward, and the lower screw 6
2. Raise the elongated hole 55 of the vertical movement lever 54 to the maximum via the turnbuckle 63, upper screw 59, upper rod 58, and shaft 57. Therefore, the lower end 51 of the vertical adjustment body 50 is spaced apart from the hopper part 14 to the maximum extent, thereby making the inlet port 15 as wide as possible.

That is, the inlet 15 is adjusted to be wide and the outlet 45 is adjusted to be narrow. In this state, brown rice is put into the circulation tank 8, and when the motor 2 is energized and the rotating shaft 4 is rotated, the downward feeding grain feeding spiral 5 fixed to the outer periphery of the rotating shaft 4 and the milling roll 6 rotate together. However, a large amount of grain that has flowed in from the inlet 15 sends the brown rice filling the grain feeding chamber 11 downward by the rotation of the downward feeding grain feeding spiral 5, and sends it to the brown rice group filling the milling chamber 21. On the other hand, the pressure inside the whitening chamber 21 is further strongly increased. When the whitening roll 6 rotates in this state, the rice grains are stirred by the stirring protrusions 7 formed on the outer periphery of the whitening roll 6, and the rice bran on the surface of the rice grains is peeled off by the strong pressure polishing action and transferred from the rice bran removing cylinder 20 to the rice bran chamber 64. The rice bran is discharged, is sucked by the rotation of the bran suction fan 27 located below, and is stored in the bran box 30.

Thus, the downward feeding grain spiral 5 continues to rotate and feeds the grains one after another into the milling chamber 21, so that the grains are polished in the milling chamber 21, descend through the outlet 45, and pass through the circulation ascending path 65. It circulates,
Circulatory ejaculation is possible. The grain then descends through the circulation ascending path 65 and flows into the grain feeding chamber 11 through the inlet 15, but as mentioned above, the vertical adjustment body 50 is raised, and there is a wide space between the hopper section 14 and the lower end 51. Since it is open, a large amount of grain flows into the grain feeding room 11.
Therefore, the pressure inside the whitening chamber 21 is high and strong pressure can be polished.

(Effects) The present invention provides a circulation tank 8, a vertically rotating downward feeding grain spiral 5 provided in the center of the circulation tank 8, a vertically rotating polishing roll 6, and the downward feeding grain feeding spiral 5 and the vertically rotating polishing roll 6. Fixed grain feeding tube 1 surrounding the outer periphery of the spiral 5
2, a vertically movable bran removing cylinder 20 that surrounds the outer periphery of the vertically rotating whitening roll 6, and an inlet 15 for grain in the circulation tank 8 formed at the upper end portion of the grain feeding cylinder 12. , an outflow port 45 formed at the lower end portion of the bran removal cylinder 20 that flows out into the circulation tank 8; and a vertical adjustment for adjusting the inflow port 15, which is provided above the inflow port 15 and is movable up and down. The body 50 and the bran removing cylinder 20 are made up of a lever 40 and a weight 44 that are moved up and down, and the outflow port 45
is configured to be adjusted in size when the bran removing cylinder 20 moves up and down, and the vertical adjustment body 50
Since the vertical circulation type rice polishing machine is configured so that when the outflow port 45 is adjusted in size by installing it on the 0 side, the outflow port 45 is also adjusted in size. It has an adjustable effect.
Further, since the bran removing cylinder 20 is also moved up and down by adjusting the lever 40, the adhering bran is dropped and cleaned.
