The rice polishing body 22 is formed of a cylindrical thin plate having a large number of small holes, and is horizontally installed.

The polished rice body 22 is made of punched metal or a lath mesh formed by expanded band processing, and its many small holes are large enough that polished rice cannot pass through. The polishing body 22 is rotated by a driving body 24,
A driven cylindrical abrasive body 23 is installed inside, and its surface is coated with a rubber material 1 having viscoelasticity, a synthetic resin material 1. Alternatively, a large number of flexible protrusions 25 are provided which are made of a flexible member such as a brush-like material that does not crush the rice grains even when the rice grains are clamped between them and the rice polishing body 22. The arrangement is axial or circumferential, linear or spiral, or a combination thereof. A motor is used as a drive body 24 for rotationally driving the abrasive body 23, and is mounted on a stand 26. The polished rice body 22 is covered with an outer casing, and has an undischarged port 28 at the end and a bran discharged port 29 below. In the figure, 30 is a rice container that receives the rice discharged from the undischarged port 28, and 32 is a rice bran container.

When polished rice is put into the hopper 21 of the rice polishing machine configured as above and the drive body 24 is rotated, the polished rice is transferred by the two flexible protrusions provided on the surface of the polishing body 23.
In the meantime, the polished rice is polished by the rotating force of the polishing body 23.
It enters into a "wedge" shape between the inner surface of the polishing body 2 and the flexible protrusion 26, and rolls on the inner surface of the polished rice body 22 while being held softly without being crushed by the elastic force of the flexible protrusion 26.
A large number of small holes and flexible protrusions 25 are provided in the polishing body 22.

By transferring with the rice body and transferring with the flexible protrusion and the rice polishing body, the rice polishing body removes the bran etc. adhering to the surface of the polished rice, and the rice is made into polished rice that can be cooked without water washing. Can be done.

Embodiment Hereinafter, an embodiment of the rice polishing machine of the present invention will be explained based on FIGS. 1 to 4.

In the figure, reference numeral 1 denotes a hopper into which polished rice is input, and a lower opening 2 is formed in the tangential direction of a cylindrical rice polishing body 3.

The rice polishing body 3 has a substantially circular shape, has no small holes near the lower opening 2, and is made of a thin plate with small holes in other parts, and is horizontally installed. Said rice body 3
A lath mesh formed by punching metal or expanded band processing is used for this, and its many small holes are large enough that polished rice cannot pass through. The rice polishing body 3 has a cylindrical polishing body rotated and driven by a driving body 6, and as shown in FIG. A rice polishing chamber 8 is formed with a gap G1 that allows the rice to pass through. A large number of flexible protrusions 6 are provided on the surface of the abrasive body 6, and the flexible protrusions 6 are made of a rubber material 2 having viscoelasticity, a synthetic resin material, a brush-like material, etc., and the abrasive body 3. It is made of a flexible member that does not crush the rice grains even if they are held between them. In this embodiment, it is formed of a brush (hereinafter referred to as a brush) that is made of nylon fiber, pig hair, or the like. As shown in FIG. 2, a small gap G2 is provided between the tip of the brush 6 and the inner surface of the rice polishing body 3, which is large enough to hold the rice grains between the two without breaking them. Note that this small gap G2
It is not necessary to provide this if the rice grains are not crushed. Also, between the brushes 6, there are provided intervals G that are large enough to allow rice grains to run between adjacent brushes vertically and horizontally, and the arrangement is linear or spiral in the axial direction or circumferential direction. Or they are arranged in combination.

The polishing body 6 is driven to rotate. A motor is used as the drive body 7, and is mounted on a stand 8.

The polished rice body 3 is covered with an outer casing 9, which has a rice discharge port 11 communicating with a rice polishing chamber 10 at its end and a bran discharge port 12 at its lower part. In the figure, 13 is a rice container for receiving rice discharged from the rice discharge port 11, and 14 is a rice bran container.

In the rice polishing machine with the above configuration, the operation is shown in Figure 1~
This will be explained based on FIG.

First, when polished rice is put into the hopper 1 and the drive body 7 is driven, the polished rice is transferred from the lower opening 2 of the hopper 1 to the rice polishing chamber 10 from the tangential direction of the polished rice body 3 due to the rotation of the polishing body 6. Inflow. In Figure 3, polished rice R flowing into the rice polishing room 10
1, as the polishing body 6 rotates in the direction of the arrow M, it comes into contact with the brush 6 and is pushed outward by centrifugal force so as to come into contact with the inner surface of the polishing body 3, and the inner surface of the polishing body 3 is moved in the direction of the arrow B. It rolls in the direction of , and the bran etc. adhering to the surface are removed by the brush 6. In addition, since the brush 6 is flexible, the polished rice R2 enters between the inner surface of the polishing body 3 and the brush 6 in a "rust" shape due to the rotational force of the polishing body 6, and the brush 6
Roll the inner surface of the polished rice body 3 in the direction of arrow C while holding the polished rice R2 softly without breaking it due to its elasticity.
Numerous small holes provided in the polished rice body 3 remove bran and the like. The rice polishing body 3 removes the rice bran and the like more strongly than the brush 6, and the rice bran and the like are reliably removed. In this way, the rice is polished and moved in the horizontal direction by the rotation of the polishing body 5, from the rice discharge port 11 to the rice container 13.
flows out to.

During this rice polishing operation, unpolished polished rice R3 is supplied from the hopper 1 to the rice polishing room 10, and the rice is polished by the same rice polishing operation as described above. Since the lower opening 2 of the hopper 1 is provided in the tangential direction of the rice grinding body 3, the remaining polished rice is smoothly transferred to the rice grinding chamber 10 without flying away.
be led to.

Further, bran and the like generated during the rice grinding are led from the lower line discharge port 12 of the outer casing 9 to the rice bran container 14 through the numerous small holes in the rice grinding body 3 and are collected therein. At this time, the lower opening 2 of the hopper 1 of the rice polishing body 3
Because there are no small holes nearby, rice polishing is rarely done. In addition, since the lower opening of the hopper 1 is formed in a substantially circular shape, bran, etc. that are generated slowly can be removed from the corner of the square, like the square opening (not shown) of a conventional rice polisher. It is unlikely that the particles will accumulate and grow, reducing the opening area and impairing the supply of polished rice into the rice polishing chamber 10. Furthermore, in FIG. 4, the lower end of the lower opening of the hopper 1 is connected to a
is shortened, and the joint portion of the rice polishing body 3 with the hopper is formed to fit therein. This means that even if the bran etc. rotated by the rotation of the polishing body 6 are blown away in the tangential direction of the flexible protrusion 6 provided on the surface of the polishing body 6, the lower opening 2 of the hopper 1 and the polished rice body 3 Since there are no joints, it is difficult for bran to accumulate there.

The above is the operation of the rice polishing machine in the embodiment of the present invention,
In the embodiment, polished rice is polished by centrifugal force using a brush 6 (flexible protrusion) disposed on the rotating polishing body 5.
The polished rice is held in contact with the inner surface of the brush 6 and rolled, and the polished rice is gently held between the brush 6 and the rice polishing body 3 and rolled, and the polished rice is polished by the rice polishing body 3. It is possible to remove bran etc. without applying strong pressure to the body 3 and without applying pressure to each other.

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.

Effects of the Invention As is clear from the description of the embodiments described above, the rice polishing machine of the present invention has a cylindrical rice polishing body with a large number of small holes and a rotatable polishing body inside the polishing body. The polished rice is rolled between the flexible protrusions and the rice polishing body, and the polished rice is rolled between the flexible protrusions and the inner surface of the rice polishing body. By removing the bran etc. from polished rice, it is possible to clean the polished rice with waterless washing and save water.
Furthermore, you can eliminate the pain of soaking your hands in cold water during the winter. Also, even if rice is intermittently supplied to the hopper,
There is no splashing of the polished rice, and the polished rice is smoothly guided to the rice grinding body and the rice is polished quickly.

Furthermore, there is almost no accumulation of bran etc. in the lower opening of the hopper.
The polishing time does not increase with use, and a constant amount of rice can be polished in a constant time.
