2. Description of the Related Art Brown rice obtained by dehulling rice hulls as a hull with a huller is polished by a rice mill to remove germ and bran layers, and is then polished and used for food. The brown rice is shown in FIG.
As shown in the figure, the sample consists of endosperm a, surrounding aleurone layer (sticky bran layer) b, germ c and bran layer d. By the way, a home-use circulating rice mill (see Japanese Patent Application Laid-Open No. 5-253501).
A paste layer remains on the surface of rice milled through a pressure-type rice mill or a commercially available milled rice such as a rice mill with a single pass or a rice mill (see JP-A-4-74539 and JP-A-5-49038). This lowers the taste and causes the smell of bran. Further, after several days from the milling, the aleurone layer is oxidized, deteriorating the quality of the rice from the surface. It is difficult to remove all of the aleurone layer without damaging the endosperm (starch layer) inside it with current rice milling technology. Therefore, immediately before cooking the rice, the rice is ground with water and the aleurone layer and oxide film are removed. Has been removed. However, sharpening rice is quite time-consuming,
It is difficult to adjust the sharpness, and there is a problem of polluting the sewage environment by discarding starch that is easily soluble in water as sharpening juice. This sharpening juice is a major source of pollution in domestic wastewater.

SUMMARY OF THE INVENTION This stirring type rice mill is
Compared to a conventional pressure-type rice mill, it has the advantage of being small in size and suitable for a small amount of rice, and can be used to mill any type of rice. However, when brown rice is polished using this agitated rice mill, the following problems have been found. That is,
In brown rice, paddy, immature rice, discolored rice, etc. are often mixed (a certain percentage is allowed by regulations), and when this is polished with a circulation rice mill or a single pass rice mill, the rice is removed. Then, the rice husks are discharged together with the bran, and the unripe rice and the colored rice are fragile and are also discharged together with the bran. However, if brown rice is polished with a stirring rice mill, the paddy will remain as it is, and unripe rice and discolored rice will remain in the polished rice basket without shattering, so that paddy, immature rice, discolored rice will be mixed in the polished rice . Such rice cannot be favored by consumers, and therefore, as a practical matter, it has to be said that this stirred rice mill is not suitable as a rice mill.

On the other hand, in the process of studying the performance of the stirring rice milling machine, the stirring rice milling machine, in addition to the above-mentioned advantages, has a good quality of cutting rice bran (branches separated from rice are well discharged,
It is possible to obtain rice with less adhesion of rice bran powder), and it is also possible to remove the aleurone layer and to make the rice grain surface glossy and smooth. Utilizing this characteristic of a stirring rice mill, it is possible to produce so-called non-washed rice in which rice can be cooked without grinding with water. In addition, this characteristic does not exist in the conventional pressure type rice mill. However, since agitated rice mills are not suitable as rice mills, after all, ordinary consumers have to use rice milled through a pressure rice mill or commercially available rice mills and have to grind with water before cooking rice. Also, a large amount of sharpening juice is continuously discharged. In addition, by this work to sharpen with water,
About 4% of the milled rice weight is lost.

In this rice washing machine, the blade member 1
It is desirable that the rotation speed of No. 3 be variable. Specifically, it is conceivable that the rotation speed can be selected, or that the rotation speed is automatically reduced in the middle of the set time.
In the latter case, for example, it is preferable that the rotation speed is initially high, and after a certain period of time, the rotation speed is automatically switched to low speed.
At this time, the rotation speed may be changed twice or more, or may be changed continuously. The reason why the rotation speed is made variable is that high-speed rotation is desirable in order to quickly remove the aleurone layer, and low-speed rotation is more desirable in order to make the surface of the rice grain glossy and smooth. In addition, low-speed rotation is also advantageous for improving rice bran and obtaining rice with less adhesion of rice flour. In low-speed rotation, the removal of the bran layer becomes sharply slow, so if, for example, it is switched from high-speed rotation to low-speed rotation when approaching the planned polishing level, the rice grain surface is smoothed after switching, Further, since the bran can be discharged from the holes of the bran removing portion 12a in the same manner as before without generating new bran, there is almost no adhesion of bran, and white rice having a glossy smooth surface can be obtained. Obtainable.
