• the rice grains 8 are successively pressed against the side walls of the container 2 by the rotating blades 4.
• the rice grains 8 pressed against the side wall rise along the side wall.
• the rice grain 8 rising on the side wall rises to a predetermined height of the container 2 due to the balance between the increasing component of the force applied to the rice grain 8 and the weight of the rice grain 8. Then, when the rice grain 8 reaches a predetermined height, the weight of the rice grain 8 becomes larger than the increasing component of the force given to the rice grain 8, and as shown in FIG.

• Such a conventional rice washer having a rice milling function has the following problems. Agitating water and rice grains using mechanical force tends to damage the rice grains, and water mixed with bran cannot be quickly separated from the rice grains. For this reason, the rice grains absorb the water with a rice bran odor, and the cooked rice becomes rice with a rice odor, and the fatty acids contained in the rice bran are oxidized to increase the heat retention odor.
• Unwashed rice which uses water in the manufacturing process, is inferior in taste because it is washed with water and then distributed in a dry state.
• Non-washed rice using sticky bran has a problem that the system is not easy to handle because the system is very large and the use of bran is not easy.
• a rice washing machine 50 having a rice-milling function has been developed as one of the purposes for removing bran 9 from brown rice.
• the power he gives to brown rice is powerful. Therefore, if white rice is introduced into the rice washer 50 and used to remove the bran 9 on the surface of the white rice, the power of the rice washer 50 system applied to the rice grains will increase the removal of the bran 9 on the surface. Is too strong and can damage starch cells on rice grain surface.
• the rice grains 8 that have risen on the side wall of the container 2 fall from the side wall portion of the container 2 and may not fall toward the substantially bottom center of the container 2 in some cases.
• the force of raising the side wall more than the own weight of the rice grains 8 depends on the input amount of the rice grains 8 and the rotation speed of the rotating blades 4.
• the rice grains 8 are not pressed up on the side wall of the container 2 and do not rise on the side wall or fall to the substantially bottom center of the container 2.
• the circulation of the rice grains 8 is not performed efficiently, and the rice grains 8 that are excessively rubbed and damage the starch cells are generated, or the rice grains 8 that cannot sufficiently separate the bran 9 are generated. Therefore, there is a problem that unevenness occurs in the washing of rice.
