Description of the Related Art Conventionally, in the above-mentioned rice polishing machine, as shown in, for example, Japanese Unexamined Patent Publication No. 5-249, it rotates around a longitudinal axis in a cylindrical body (inner peripheral portion of the bran removing cylinder). A brush is planted on the outer peripheral part of the driven cylindrical rotor, and a vertical low speed conveyor conveys a desired low speed for grinding while the rice grains are pushed upward from the lower side to the upper side. There was a structure in which the rice bran remaining on the surface of the rice grain was scraped off by the brush.

体とが共に円筒形状であるから、これらが組付けられた
状態では上記接触圧力は常に一定の値に設定されるもの
となる。That is, as described above, in the structure in which the bran adhered to the rice grains is scraped off by the grinding action of the brush, the brush and the cylindrical body on the outer side of the brush are kept in a state in which the brush has a predetermined contact pressure with respect to the rice grains. However, in the above conventional configuration, the contact pressure is always set to a constant value when the brush and the tubular body are both in a cylindrical shape. It will be one.

ればならず、大幅なコストアップを招く不利があった。As a result, for example, when it is necessary to make the contact pressure different depending on the use of the rice to be ground, such as for edible or brewing, the brush or the cylindrical body may have different specifications with different diameters. It is necessary to separately prepare the above, and it is necessary to have different specifications for each use as described above, which is a disadvantage in that the cost is significantly increased.

雑になる不利もあった。Further, the passage of rice grains is also cylindrical, and the inner peripheral surface of the cylinder is composed of a smooth surface. Therefore, in order to ensure grinding, the vertical screw as described above is used. There is also a disadvantage that the structure becomes complicated because a conveyer or the like is required as a conveying means.

同時に吸引排出されることになる。A suction fan 26 as ventilation means is connected to the internal space S2 of the cylindrical case 2 via an exhaust pipe 25, and an intake port 27 is formed in the upper case 3. By the suction operation (ventilation operation) of the suction fan 26, the air sucked through the suction port 27 is sucked through the passages 24 formed in the outer support 10 from the rice polishing action portion by the brushes 7 and 9. Is sucked into
The rice is discharged from the dust outlet 28 to the outside of the machine, but at this time, the bran scraped off in the part where the brushes 7 and 9 act to polish the rice is also sucked and discharged.

Is directed toward the upper side relative to the relative rotation direction, that is, toward the upper side in the rotating direction of the inner brush 7 that rotates in a predetermined direction, and toward the lower side in the rotating direction of the inner brush 7 in the position-fixed outer brush 9. It is planted in a state of having a receding angle, and the free end side is bent and formed along the normal direction toward the mating brush. By giving a receding angle in advance in this way, as shown in FIG. 3, when the grinding action of rice grains is performed, for example, as compared with the case where the rice grains are planted in the normal direction, The bending angle at the root portion is small, and the durability is improved. Moreover,
Since the free end side is bent toward the mating brush in the direction along the normal direction, the tip of the free end side should be in contact with the rice grain in a posture almost orthogonal to the blade to exert an effective bran scraping function. You can

By opening the rice grain, the rice grains supplied to the storage space S1 in the upper case 3 are diffused almost uniformly in the storage space S1 by these diffusion vanes 29, and the bottom surface of the upper case 3 is tapered and tapered. The guide surface 3a formed on the
Rice grains are designed to flow down between the brushes 7 and 9. The inner brush 7 is arranged such that the upper end thereof is located below the upper end of the outer brush 9, and the outer end position of the diffusion blade 29 faces the stepped portion between the inner brush 7 and the outer brush 9. The rice grain is set so as to be positioned, and the rice grains discharged outward by the diffusion blades 29 are effectively guided between the brushes 7 and 9.

While being scraped off, it slowly passes between the brushes 7 and 9 downward due to its own weight and the weight of another rice grain supplied from above. At this time, the scraped bran is discharged from the dust outlet 28 to the outside of the machine by the ventilation operation of the suction fan 26 as described above. Then, the rice grains from which the bran has been removed by passing to the lower end portions of the brushes 7 and 9 are dropped and collected by the collecting unit 30 arranged inside the base 1.
