関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sorting method and a sorting device for sorting, separating, and recovering germs from rice bran produced during milling operations.

従来技術とその問題点 米胚芽には、ビタミン類が豊富に含まれており、健康食
品として最近特に注目されているが、高率的な胚芽の回
収方法が未開発で従来胚芽を残存させて搗精したいわゆ
る胚芽精米として一般に利用されている程度であった。Conventional technology and its problems Rice germ is rich in vitamins and has recently attracted particular attention as a health food. It was generally used as germ-polished rice.

通常の精米機による搗精では、胚芽は精白米から脱落し
てしまい、多孔壁精白筒から抜は落ちる粗糖中に混入し
て排出され、胚芽の形では有効に利用もされず、同時に
排出される砕米も含めて単に粗糖として処理されていた
。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.

回収が容易な方法とは言えなかった。In response to this, attempts have been made to separate and recover the germ from raw sugar. Separation of germ from rice bran, which consists of a step of sorting the raw sugar obtained from this step according to the size of the broken rice mixed in it, and a step of putting the mixture from this sorting step into a vibrating sieve to separate and recover the germ. ``Method'' is known, but it is an application of the technology used for wheat flour milling, and the entire amount of the material to be processed is passed through a vibrating sieve device.
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 under pressure, causing deformation or scratches on the surface, which reduces its value. It was a thing. Furthermore, as shown in Japanese Patent Application Laid-Open No. 55-109473, a sorting net made of a wire mesh that allows the bran to pass through but not the germ and broken rice is tilted in two directions and swung, and the bran is removed from the bottom of the wire mesh. A method of separating bran, germ, and crushed ice has been proposed, in which the germ and crushed rice are sorted by shaking on a sorting net, as well as being blown up by a breeze from the ground, but in reality, there are many variations in the grain size of the crushed rice, Even if the rice is blown up and removed, it is difficult to separate the germ and broken rice by shaking the rice, resulting in a high rate of separation and separation of the germ.
It was not an easy method to recover.
