This will be explained based on FIGS.

First, when polished rice is put into the hopper 1 and the driving body 6 and the air flow generator 12 are driven, the polished rice flows into the rice polishing chamber 8 due to the rotation of the polishing body 6 and the suction force. In FIG. 3, as the polishing body 6 rotates in the direction of arrow A, the polished rice R1 flowing into the rice polishing chamber 8 comes into contact with the brush 5a and comes into contact with the inner surface of the polishing body 2 due to centrifugal force. The rice polishing body 2 is pushed outward and rolls on the inner surface of the polishing body 2 in the direction of arrow B, and the bran and the like adhering to the surface are removed by the brush 6a. In addition, since the brush 5a has flexibility, the polished rice R2 is wedged between the inner surface of the polishing body 2 and the brush 6a due to the rotational force of the polishing body 50, and the elasticity of the brush 6a While holding the polished rice R2 softly without shattering it, roll the inner surface of the polished rice body 2 in the direction of arrow C.
The rice bran etc. are removed through the many small holes provided in the holder. The removal action of rice bran etc. by this rice polishing body 2 is stronger than the removal action by the brush 5a, and the bran etc. are removed reliably. In this way, while being polished, the rice is moved in the horizontal direction by the rotation of the polishing body 6 and the suction force of the air flow generator 12, and the pressure regulating valve 4 provided at the undischarge port a is opened to transfer the rice to the rice container 13. and leaks out.

During this rice polishing operation, unpolished polished rice R3 is supplied from the hopper 1 to the rice polishing chamber 8, and the rice is polished by the same rice polishing operation as described above. The last remaining polished rice is also guided to the rice polishing chamber 8 by the suction force of the airflow generator 12. In addition, the bran etc. generated during the rice polishing are passed through the suction port 9 between the rice polishing body 2 and the polishing body 6, and are passed through the suction port 11 of the outer casing 1o from the numerous small holes of the rice polishing body 2. Air flow generator 12
The rice bran is completely separated from the polished rice and collected in the bran container 14. Note that the intake port 9 is formed with a hole smaller than the rice so that the rice does not pass through.

The above is the operation of the rice polishing machine in the embodiment of the present invention,
In the embodiment, polished rice is brought into contact with the inner surface of the polished rice body 2 by centrifugal force and rolled by a brush 5a (flexible protrusion) disposed on the rotating polishing body 5. Since the polished rice is gently held between the rice polishing body 6a and the rice polishing body 2 and rolled and polished by the rice polishing body 2, the polished rice is not pressed strongly against the rice polishing body 2, and the polished rice is It is possible to remove bran etc. without applying pressure to each other. Also, rice research room 8
As the milled rice is cooled by the air flowing through it, it is possible to eliminate oxidation caused by heat generation in the rice.

In addition, in the embodiment, the flexible protrusion was explained as being composed of a brush, but it is made of rubber having viscoelasticity.

The same operation and effect can be obtained even if it is made of synthetic resin or the like. Further, in this embodiment, a horizontal type is used in which polished rice is fed by the rotation of the abrasive body 2, but it may be a vertical type in which polished rice flows down from above. moreover,
Although a suction device is used as the air flow generating device 12 in the embodiment, similar effects can be expected even if it is an air-pushing type.

When water for cooking was added to the polished rice washed in this manner, the turbidity of the water was compared with that of water-washed rice, but there was no difference between the two. It was confirmed that the rice polishing machine was sufficiently usable for practical use.

Effects of the Invention As described above, the rice polishing machine of the present invention includes a rotatable polishing body inside a cylindrical rice polishing body having a large number of small holes, and a large number of flexible protrusions on the surface of the polishing body. The polished rice is rolled between the flexible protrusion and the rice polishing body, and the rice bran, etc. of the polished rice is removed by rolling the polished rice between the flexible protrusion and the inner surface of the rice polishing body. 5, and the air flow generator completely separates the polished rice from the rice bran, etc., so that the polished rice can be cleaned without water washing, and the polished rice does not break up during polishing. By doing so, you can save water, eliminate the pain of soaking your hands in cold water in winter, and avoid oxidation and deterioration of rice due to the heat generated during rice grinding. Furthermore, by considering the air flow generated by the air flow generator, excellent effects can be achieved, such as completely discharging all the polished rice down to the last polished rice.
