水を必要とする。2. Description of the Related Art Generally, rice is washed to cook rice.
This rice washing step is an important step that affects the taste of cooked rice, and is a very time-consuming step. Therefore, there are many devices for automating the rice washing process to save labor. However, water and rice stirred by mechanical force tend to damage rice, and water mixed with bran cannot be quickly separated from rice. It becomes odorous rice, and furthermore, the fatty acids contained in the bran are oxidized to increase the heat retention odor. In addition, there is a method in which rice is rubbed by running water in running water, but a large amount of water is required.

としての糠の除去性能が劣っている。[0003] There is also non-washed rice sold without the bran, but non-washed rice using water has a poor taste because it is dried and distributed after using water, and unwashed rice using sticky bran. The system is very large and the use of bran is difficult to handle as a household appliance.Washed rice using a brush is relatively simple, but the rice bran removal performance as unwashed rice is poor. I have.

In a device for removing rice bran and separating rice grains and bran as in 0-5989, if the rice bran removal accuracy is improved and rice washing is performed without using water, it acts on brown rice to remove bran from brown rice. The power is too strong to remove the bran on the surface of the white rice grains, which damages the starch cells on the surface of the rice grains, easily causing the starch to flow out during cooking, and damaging the physical properties such as stickiness of cooked rice and adversely affecting the taste Will occur.
Also, depending on the amount of treatment, for example, when a small amount is treated, the above-mentioned effect of damaging the rice surface is likely to occur, and when a large amount is treated, the bran removal performance tends to be uneven.

適さないため、その無洗米を水に浸けると水が白濁しや
すくなり、十分な洗米処理ができているとは言えない。As described above, when rice is immersed in water in rice washing, the bran component once dissolved in water is absorbed by the rice again, so that water is not used or water is not used as much as possible. It is desirable that the rice that has absorbed water becomes brittle, so that it is very difficult to control the mechanical force by applying mechanical force such as stirring to the rice that has absorbed water. In addition, even if water is not used, the brush alone can remove the bran fragments remaining on the rice grain surface, but it is not suitable for removing the part containing the bran component covering the rice grain surface. Water becomes cloudy easily, and it cannot be said that the rice has been washed sufficiently.

【０００６】さらに、精米器の構成では精白米の糠を除
去する力が強すぎるため、米粒表面の澱粉細胞を傷つけ
易い。[0006] Further, in the configuration of the rice mill, the power of removing the bran of the polished rice is too strong, so that the starch cells on the rice grain surface are easily damaged.

の労力を軽減するものである。Accordingly, in the present invention, the water acting on the rice grains is made uniform and appropriate even if the amount of treatment is large or small, without using water, so that the surface of the rice grains is not damaged and the surface of the rice grains is not damaged. It removes only bran and reduces the labor of manual rice washing.

By operating an operation switch (not shown), the drive means 1 starts rotating, and the drive shaft 2 and the rice washing blade 3 fitted to the drive shaft 2 are rotated. By the rotation of the rice-washing blade 3, the rice-washing unit 5 applies a tangential force of rotation to the rice grains that come into contact with the side of the rice-washing container 4 while keeping a constant interval,
The rice grains are pressed against the side of the rice washing container 4 and rise along the side. Since the rice grains are continuously generated up to the height at which the rice washing section 5 is arranged, the rice grains which have risen higher than the tip of the rice washing section 5 lose force and fall freely, and return to the bottom surface of the rice washing container 4. The rice grains come into contact with the rice-washing blade 3 again or receive a force due to the flow of air generated by the rice-washing blade 3, move to the side surface, and repeat the same operation. By continuing this circulation for a certain period of time, the rice grains rub against each other while changing the direction at random, and the bran on the surface is gradually removed. Therefore, the starch grains on the surface of the rice grain are hardly damaged, and the rice grains after the treatment are easily separated from the bran, reducing the rice washing operation by hand washing, and obtaining a good taste in which the surface of the cooked rice does not crumble and become sticky even when cooked. Rice grains can be made.

良好な食味を得る米粒を作成することができる。The operation of the above arrangement will be described. Rice grains of polished rice for washing rice are put into the washing rice container 4. By operating an operation switch (not shown) in the same manner as in the first embodiment, the drive unit 1 starts rotating, and the drive shaft 2 and the rice washing blade 3 fitted to the drive shaft 2 are rotated. The rotation of the rice washing blade 3 causes the rice washing section 5 to apply a force to the rice grains in contact with the rice washing section 5 while moving the rice grains to the side of the rice washing container 4 while keeping a constant distance from the side of the rice washing container 4. Further, the free end of the presser blade 9 is rotated while spreading to the side surface of the rice washing container 3 by the centrifugal force generated by the rotation of the rice washing blade 3, thereby pressing the rice grains moved to the side surface by the rice washing part 5 against the side surface, and the free end is Since it is rotatable, the position can be changed according to the amount of pressed rice, and rice grains are not pinched and broken. The pressing force of the pressing blades 9 is generated between the rice grains, so that the rice grains rise along the side surfaces while rubbing each other. Since this force occurs up to the height at which the rice washing section 5 is arranged, the rice grains rising above the tip of the rice washing section 5 fall freely and return to the bottom of the rice washing container. When the rice grains again come into contact with the rotating rice washing blade, they receive centrifugal force again, move to the side surface side, and repeat the same operation. By continuing this circulation for a certain period of time, the rice grains rub against each other while changing the direction at random, and the bran on the surface is gradually removed. Therefore, the starch grains on the surface of the rice grain are hardly damaged, and the rice grains after the treatment are easily separated from the bran, reducing the rice washing operation by hand washing, and obtaining a good taste in which the surface of the cooked rice does not crumble and become sticky even when cooked. Rice grains can be made.

While raising along the side. The friction force of the rice grains in contact with the rice washing section 5 is increased due to the unevenness of the surface of the rice washing section 5, so that the power is efficiently transmitted to the rice grains, and there is also an effect of removing the rice bran in the concave portions on the rice grain surface. Since this force occurs up to the height at which the rice washing section 5 is arranged, the rice grains that have risen higher than the tip of the rice washing section lose their power, fall freely, and return to the bottom surface of the rice washing container 4. The rice grains are again brought into contact with or near the rice-washing blade 3 and receive a force due to the flow of air generated by the rice-washing blade 3, move to the side surface, and repeat the same operation. By continuing this circulation for a certain period of time, the rice grains rub against each other while randomly changing their directions, and the bran on the surface is gradually removed. Therefore, the starch grains on the surface of the rice grain are hardly damaged, and the rice grains after the treatment are easily separated from the bran, reducing the rice washing operation by hand washing, and obtaining a good taste in which the surface of the cooked rice does not crumble and become sticky even when cooked.

得る米粒を作成することができる。The operation of the above arrangement will be described. Rice grains of polished rice for washing rice are put into the washing rice container 4. By operating an operation switch (not shown) in the same manner as in the first embodiment, the drive unit 1 starts rotating, and the drive shaft 2 and the rice washing blade 3 fitted to the drive shaft 2 are rotated. The rotation of the rice washing blade 3 causes the rice washing section 5 to apply a force to the rice grains in contact with the rice washing section 5 while moving the rice grains to the side of the rice washing container 4 while keeping a constant distance from the side of the rice washing container 4. Further, the free end of the holding blade 9 is rotated while spreading to the side of the rice washing container 4 by the centrifugal force generated by the rotation of the rice washing blade, thereby pressing the rice grains moved to the side by the rice washing section 5 against the side, and the free end is rotated. Because it ’s free to move,
Since the position is changed according to the amount of pressed rice, the rice grains are not pinched and broken. The rice grains rub against each other by generating the pressing force of the pressing blades 9 between the rice grains, and the pressing brush 13 on the side surface of the pressing blades 9 is pressed against the rice grain surface to sweep out and remove the bran in the concave portions along the side surfaces. And raise it. Since this action occurs up to the height at which the rice washing section 5 is arranged, the rice grains that have risen higher than the tip of the rice washing section 5 lose their power, fall freely, and return to the bottom of the rice washing container 4. At this time, the finishing brush 14 provided inside the pressing blade 9 removes the bran that cannot be removed while ascending along the side surface to finish the surface.
The rice grains come into contact with or come close to the rotating rice-washing blade 3 again, receive a force due to the flow of air generated by the rice-washing blade 3, move to the side, and repeat the same operation. By continuing this circulation for a certain period of time, the rice grains rub against each other while changing the direction at random, and the bran on the surface is gradually removed. Therefore, the treated rice grains are easily separated from the bran with little damage to the starch cells on the rice grain surface, reducing the rice washing operation by hand washing,
It is possible to produce a rice grain that obtains a good taste in which the surface of the cooked rice does not collapse even when cooked.

ど付かず、メンテナンスも楽になるように感じます。The operation of the above arrangement will be described. Rice grains of polished rice for washing rice are put into the washing rice container 4. By operating an operation switch (not shown) in the same manner as in the first embodiment, the drive unit 1 starts rotating, and the drive shaft and the rice washing blade 3 fitted to the drive shaft are rotated. The rotation of the rice washing blade 3 causes the rice washing section 5 to apply a force to the rice grains in contact with the rice washing section 5 while moving the rice grains to the side of the rice washing container 4 while keeping a constant distance from the side of the rice washing container 4. Further, the free end of the holding blade 9 is rotated while spreading to the side of the rice washing container by centrifugal force generated by the rotation of the rice washing blade, thereby pressing the rice grains moved to the side by the rice washing section 5 against the side, and the free end is rotated. Because it is flexible, the position is changed according to the amount of pressed rice, so that rice grains are not pinched and broken. The rice grains rub against each other by the pressing force of the pressing blades 9 generated between the rice grains, and are pressed against the surface of the rice grains by the pressing brush 13 on the side surface of the pressing blades 9 to sweep out and remove the bran in the concave portions along the side surfaces. Rise. The removed bran is discharged to the outside of the rice washing container 4 from the opening on the side surface of the rice washing container 4 by the centrifugal force and the flow of air generated by the rice washing blade 3 or the holding blade 9, and does not return to the rice washing container 4. Since this action occurs up to the height at which the rice washing section 5 is arranged, the rice grains rising above the tip of the rice washing section fall freely and return to the bottom of the rice washing container 4. At this time, the brazing brush 14 provided inside the pressing blade 9 removes the bran that cannot be removed while ascending along the side surface to finish the surface. When the rice grains come into contact with the rotating rice washing blade 3 again, they receive centrifugal force again, move to the side surface side, and repeat the same operation. By continuing this circulation for a certain period of time, the rice grains rub against each other while changing the direction at random, and the bran on the surface is gradually removed. Therefore, the starch grains on the surface of the rice grain are hardly damaged, and the rice grains after the treatment are easily separated from the bran, reducing the rice washing operation by hand washing, and obtaining a good taste in which the surface of the cooked rice does not crumble and become sticky even when cooked. Rice grains can be made. Also, when the brush 13 is inserted, almost no bran sticks to the groove of the brush due to the centrifugal force, and it feels easy to maintain.
