Further, a bottom plate 2b provided with an outlet 2d for polished rice after polishing in the center is attached to the lower edge thereof. For the grain-polishing body 2, a punching metal or a lath mesh-shaped one formed by an expanding process is used, and a large number of small holes thereof have a size such that polished rice cannot pass through. Reference numeral 3 denotes a cylindrical polishing body which is installed in the polishing body 2 and is rotationally driven by a driving body 4. As shown in FIG. 3, rice grains are provided between the outer peripheral surface and the inner surface of the polishing body 2. A gap C ₁ is provided to allow the rice to flow down, and a rice polishing chamber 8 is formed. The polishing body 3 is detachably attached to the rotary shaft 4a of the driving body 4, and the rotation is transmitted by the key 4b. 3a is a large number of flexible protrusions arranged on the surface of the polishing body 3, and holds rice grains with the polishing body 2 such as a viscoelastic rubber material, synthetic resin material, or brush-like one. Even if the rice grain is not crushed, it is made of a flexible material. In this embodiment, the brush is made of nylon fiber, pig hair or the like (hereinafter referred to as a brush).
Between the tip of the brush 3a and the inner surface of the polished body 2,
As shown in FIG. 3, a small gap C ₂ is provided so that both can hold the rice grains without crushing them. The small gap C ₂ may be omitted if the rice grains are not crushed. Further, between the brush 3a vertically, horizontally rice grains between Aitonaru brush mutual degree of clearance C ₃ which can flow down or transverse provided, the sequence, in a linear or spiral in the axial direction or the circumferential direction They are aligned or arranged by combining them. A motor is used as a driving body 4 that rotationally drives the polishing body 3, and is mounted on a table 5. Reference numeral 6 denotes an outer casing that covers the polished rice body 2. The outer casing 6 has an intake port 6a for sucking outside air in a tangential direction of the outer casing 6.
And a suction port 6b for sucking air sucked into the outer casing 6 in a tangential direction is provided, and the suction port 6b is connected to the air flow generator 7. The air flow generator 7 is a suction device in this embodiment, and includes a suction motor 7a and a fan.

Reference numeral 9 denotes a shooter for discharging the polished rice that has been polished from a rice discharging port 9a that is opened in the table 5 below the polishing body 3.

Next, the operation of the rice polishing machine having the above structure will be described with reference to FIGS. 1 to 4.

First, when milled rice is put into the hopper 1 and the polishing body 3 is rotated in the direction of arrow A (FIG. 4) by the driving body 4, the milled rice flows into the polishing chamber 10. The milled rice R ₁ that has flowed into the polishing chamber 10 flows down between the brushes 3a, but in the process, it comes into contact with the brushes 3a and is pushed outward by centrifugal force so as to contact the inner surface of the polishing body 2, The inner surface of the rice body 2 is rolled in the direction of arrow B, and the bran and the like adhering to the surface is removed by the brush 3a. Further, since the brush 3a has flexibility, the rotating force of the polishing body 3 causes the polished rice R ₂ to enter a “wedge” shape between the inner surface of the polishing body 2 and the brush 3a, and the elasticity of the brush 3a causes The milled rice R ₂ is crushed gently without being crushed, and the inner surface of the grain-polishing body 2 is rolled in the direction of arrow C, and the bran and the like are removed by the numerous small holes provided in the grain-polishing body 2. The removal action of bran or the like by the polished rice body 2 is stronger than the removal action by the brush 3a, and the bran or the like is surely removed. Then, the removed bran or the like flows through the air flow generator 7 from the intake port 6a of the outer casing 6 to the suction port 6b while swirling through the inside of the outer casing 6, the outlet 1a of the hopper 1, and the exhaust air. The air flowing in from the rice mouth 9a is sucked from a large number of small holes provided in the grain-polishing body 2 and guided to the cyclone 8 from the suction port 6b.
In the cyclone 8, the bran and the like are separated from the air by the difference in centrifugal force, and clean air is discharged through the fan 7b and the suction motor 7a, and the bran and the like are collected in the bran container 8a.

During such a polishing operation, unpolished polished rice R ₃ is replenished from the hopper 1 to the polishing chamber 10 and polishing is performed by the polishing operation similar to the above.

The above-described polishing with the brush 3a and polishing with the brush 3a and the polishing body 2 performed at random are performed on polished rice at random, but a large number of brushes 3a are provided. Therefore, the milled rice is not discharged from the rice discharge port 7a as unmilled rice while flowing down the polishing room 8.

The above is the operation of the rice polishing machine in the embodiment of the present invention.
In the embodiment, the brush 3a (flexible protrusion) provided on the rotating polishing body 3 is used to centrifuge the milled rice 2 by centrifugal force.
The milled rice 2 is brought into contact with the inner surface of the mill to roll the milled rice, and the milled rice 2 is gently sandwiched between the brush 3a and the milled rice body 2 to roll the milled rice and the rice miller 2 polishes the rice bran and the like. Since they can be separated more completely, the bran and the like can be removed without strongly pressing the polished rice against the milled rice body 2 and without applying a pressing force to the polished rice. This allows
The generation rate of broken rice is extremely low, and the air flow generator 7 can completely remove bran and the like from the rice, and further, the air flowing in the milled body 2 can eliminate the oxidation caused by the heat generation of the rice. It is a thing. In particular, since air is taken in in the tangential direction of the outer casing 6 and discharged in the tangential direction, it becomes a complete swirling flow, and this flow can effectively remove bran and the like.

In the embodiment, the flexible protrusion 3a has been described as a brush, but the same operation and effect can be obtained even if it is made of rubber having viscoelasticity, synthetic resin, or the like. Further, although the air flow generating device 7 is an example of a suction device, it may be an air pushing type.

Further, in this embodiment, the milled rice is of a vertical type that flows down from above, but it may be of a horizontal type and the milled rice may be fed by rotating the polishing body.

Water for cooking rice was added to the polished rice thus washed with anhydrous water, and the turbidity of the water was compared with that of wet hand washing, but there was no difference between the two, and an example of the present invention was obtained. It was confirmed that the above-mentioned rice polishing machine could be put to practical use.

EFFECTS OF THE INVENTION As described above, the rice polishing machine of the present invention has a cylindrical rice polishing body having a large number of small holes and a rotatable polishing body provided with a large number of flexible protrusions on the surface thereof. , The polished rice is rolled by the flexible protrusion of the polishing body and the polishing body to remove the bran etc. of the polished rice, and without removing the removed bran etc. to the surface of the polished rice, Since it is designed to be completely separated by the swirling flow of air in the tangential direction, it is possible to clean the polished rice with anhydrous washing, and the polished rice is not crushed at the time of polishing. , Oxidation due to the heat of rice disappears. And with these, you can save water,
Further, it is possible to eliminate the pain of immersing the hands in cold water in winter, and it is possible to eliminate the unpleasant appearance and the waste caused by the occurrence of broken rice, which is an excellent effect.
