Description

TECHNICAL FIELD [0001] The present invention relates to a rice grain separating system and a rice grain separating method using the system.

The present invention relates to a rice grain separating system and a rice grain separating method using the system, and more particularly, to a system and a method for separating high-purity rice grain from rice bran containing raw rice, Thereby effectively obtaining a rice grain having a purity of 95% or more.

Generally, the harvested rice is brown rice after drying and threshing and after removing rice hulls. Brown rice contains white rice, which is a starch layer in the inside of the perilla and rice bran.

Rice bran is a mixture of rice bran, crushed rice, rice gruel, and other foreign matter as a crushed mixture which is generated during the process of converting brown rice into white rice.

About 6 ~ 8% of brown rice is separated into rice bran during the ripening process and its amount is increased or decreased according to the degree of separation of rice bran, crushed rice, and rice husk (embryo). For example, the 5th minute is half of the rice and half of the rice is halfway between the brown rice and the white rice, the 10th minute rice is 100% peeled rice from the brown rice, and the 12th rice is the normal white rice which is 120% .

The higher the degree of corrugation, the lower the major nutrients and fiber such as protein, fat, and vitamins, but the higher the digestibility and the better the texture. This is why rice cooked with white rice tends to have a higher preference than rice brown rice.

On the other hand, as described above, rice bran removed through the digestion process contains 95% of rice nutrients. In particular, since more than 65% of the rice bran is concentrated in the rice bran, researches for utilizing the rice bran as a raw material of food have been actively conducted.

Since the rice bran contains a large amount of lipase, lipase, it causes the increase of free fatty acid to promote rancidity, and various odor is generated in the process of rancidity, so that it can not be used as food.

Accordingly, Korean Patent No. 10-1359615 discloses a technology for utilizing such raw rice as a food material by inactivating lipase to heat it, but there is a disadvantage that elution and deterioration of nutrients by high temperature steam are inevitable.

In view of the above-mentioned problems, recently, a method of separately separating rice husks contained in rice bran using a rice grain separating apparatus equipped with a vibrating body has been used.

For example, in a technique disclosed in Korean Patent No. 10-1504909, there is a step of obtaining a raw rice containing brown rice with brown rice, a step of removing the raw rice from the rice bran by separation of specific gravity, Is divided into rice husks and rice bran through a vibrating body of 30 to 40 mesh to separate the rice husks.

As another example, Korean Unexamined Patent Publication No. 10-1335980 discloses a technique in which a backbone is inserted into a vibrator module equipped with a mesh network, and then primary vibrations And a secondary vibrating screening step of obtaining a rice ball or hooves remaining in the mesh net through a vibrating process after putting a beak carried out from the primary vibrating screening step into a vibrator module equipped with a mesh net, .

Korean Patent No. 10 - 1359615 (Feb. Korean Patent No. 10 - 1504909 (Feb. 23, 2013) Korean Patent No. 10 - 1335980 (December 3, 2013)
