。When milling with a normal rice mill, the germ falls off from the polished rice and is mixed with the raw sugar that falls from the porous wall milling barrel and discharged, and is not effectively utilized in the form of the germ and is discharged at the same time. All rice, including broken rice, was simply treated as raw sugar.

言えなかった。In response to this, attempts have been made to separate and recover the germ from raw sugar. For example, as shown in Japanese Patent Publication No. 58-45304, one bran is extracted by "preliminarily sorting fine particle size classification". 11 No. 2 "This is the second step" I Separate the 19 raw sugar from the culm according to the size of the crushed ice mixed in it. A method for separating germs from rice bran consisting of T culms to be recovered is known, but it is an application of the technology that has been used in wheat milling, and the grain of the material to be processed is passed through a vibrating sieve. The size of the vibrating sieve equipment used has increased, and the need to collect the germs with a cyclone requires larger blowers and suction machines.Depending on the particle size of the broken rice being mixed, it is necessary to make it easier to sort the rice. It is necessary to crush only the broken rice through a crushing roll machine, and when the broken rice is crushed, the germ is compressed and may become deformed or have a defect on its surface that causes mountains to lower its if value. The equipment was large-scale. Also, JP-A-55-109'l
As shown in Publication No. 73Q, a sorting screen made of wire mesh that allows the bran to pass through but not the germ and broken rice is swung in two directions (tilt), and the bran is blown up by a breeze from the bottom of the wire mesh. In addition to the removal method, a method of separating bran, germ, and broken rice by separating the elbows, germs, and broken rice on a sorting net or by shaking them has been proposed, but in reality, there are many variations in the particle size of the crushed ice, and the bran is separated by a breeze. Even if the blasting was removed, the liver seal and broken rice could not be separated by shaking sorting alone, and it could not be said that it was an easy method to separate and recover germs at a high rate.
