The resistor is provided with a slit in a direction crossing the grain movement direction or a slit in a direction parallel to the grain movement direction.

(Problems to be Solved by the Invention) Since the slits in the above-mentioned known examples are formed by cutting, there are problems that the processing is difficult and that the effects of the slits are not so great. Therefore, a resistor that does not use slits is formed to increase the friction, thereby making processing easier and improving the friction effect.

(Means for Solving the Problem) Therefore, the present invention has a polygonal rice polishing cylinder 13 with a resistor mounted on the inner surface of the corner, and the resistor has an inclined surface that gradually approaches the rice polishing roll 17 from the front edge to the center. The resistor of the rice milling device has an inclined surface that gradually moves away from the rice milling roll 17 from the center to the rear edge.

A cross section is shown in Fig. 3.

The whitening tube 13 is formed by forming a thin iron plate without a bran removal hole 18, and one whitening tube 13 is formed by combining four pieces bent in the shape of a square. 19 is a vertical column of four trees installed on the front, back, left and right sides. The vertical column 19 is fixed to a framework, and a resistor element is attached to the inner surface of the column with screws 44, which serves both to attach the polishing tube 13 and to rub the rice grains.

The resistor 20 has approximately the same vertical length as the polishing cylinder 13, and its left and right width is wider than the vertical column 19, and from the front edge 21 to the center 24 is an inclined surface 46 that gradually approaches the rice polishing roll 17.
Then, from the center 24 to the rear edge 45, the rice polishing roll 1 is gradually removed.
7. The inclined surface 47 is made to be away from 7.

The resistor 20 protrudes left and right from the vertical column 19, and the end of the polishing tube 13 is brought into contact with it from the outside as shown in FIG. 19
When the screw n is inserted into the through hole provided in the U-shaped presser 22 and screwed onto the vertical column 19 and tightened, the tip of the U-shaped presser η is inserted. , fix the polishing cylinder 13. When the screw 23 is loosened, the presser η is removed and the polishing tube 13 can be replaced.

The resistor 20 is located inside the center of the dogleg-shaped polishing tube 13.
A resistor of the same shape is brought into contact with the resistor and fixed from the outside with a stopper 25.

The rice milling trochanter 17 has a hollow pipe 26 at its center, the hollow pipe 26 is connected to the rotating shaft 15, and has a ventilation port 27. A gap 28 is provided on the outer periphery of the hollow pipe 26, and a mounting cylinder 29 is provided outside the gap 28. The outer surface of the mounting cylinder 29 is provided with vertical slits 3 at predetermined intervals.

As shown in FIG. 2, the rice polishing trochanter 17 may be formed in a two-tiered structure, one above the other.

(effect) Next, we will discuss the effect.

When grains are supplied from the supply hopper 8, the grains flow into the milling chamber 42 through the interior of the supply cylinder 7. Therefore, when the rotating shaft 15 is rotated by the motor via the pulley 16, the rice polishing trochanter 17 rotates to the left in FIG. The resistor 20 has an inclined surface 46 that gradually approaches the rice milling roll 17 from the front edge 21 to the center 24, and an inclined surface 47 that gradually moves away from the rice milling roll 17 from the center 24 to the rear edge 45. As the rice is polished, the grains are gradually subjected to sharp friction and rubbing action by the inclined surface 46 approaching the rice polishing roll 17. , when flowing out to the lower side of the rice milling roll piece 32,
The bran is removed by the blast of air passing through the ventilation port n, the gap 28, the passage 31, and the jet port 41, and the free bran is discharged to the outside of the machine through the sugar removal hole 18.

(Effects) The conventionally known Japanese Patent Application Laid-Open No. 61-222544 describes an invention in which a resistor is attached to the inner surface of a polygonal rice polishing cylinder. The resistor is provided with a slit in a direction crossing the grain movement direction or a slit in a direction parallel to the grain movement direction. Since the slits in the above-mentioned known examples are formed by cutting, the processing is difficult, and the effect of the slits is only to increase the sliding resistance, so we cannot expect much particle friction. However, there is a problem that the rice polishing effect is not as high as expected.

However, in the present invention, a resistor is attached to the inner surface of the corner of a polygonal rice polishing cylinder 13, and the resistor is an inclined surface that gradually approaches the rice polishing roll 17 from the front edge to the center, and from the center to the rear edge. is used as a resistor of the rice milling device, which has an inclined surface that gradually becomes farther away from the rice milling roll 17.
When the rotating shaft 15 is rotated and the rice polishing trochanter 17 is rotated, when the rice polishing roll piece 32 comes to the position facing the resistor 20, the slope 46 from the front edge 21 to the center 24 of the resistor 20 gradually The rice is strongly polished due to both the particle friction and the sliding action that become stronger, and the strong pressure is released all at once on the inclined surface 47 from the center 24 to the rear edge 45 of the resistor 20, and the rice is agitated. As a result, the rice bran is removed and the rice bran is removed, and the rice bran is discharged outside the machine. Therefore, since the resistor 20 does not require slit processing, it is extremely easy to manufacture, and since milling is performed repeatedly with one strong pressure and release, the rice milling efficiency is dramatically improved.
