Description

Rice Bran Screening Device

The present invention relates to a rice grain screening apparatus, and more particularly, to a rice grain screening apparatus that applies vibration to a plurality of stacked meshes horizontally and vertically to thereby easily sort fine grains and rice grains.

In general, rice husk is obtained as a by-product from rice husks and rice bran in the process of obtaining rice bran. In general, rice husk is used as a fuel or as a rug for housing, and rice bran is used for feed or oil extraction.

Currently, the world's rice producing countries that produce high-value-added high quality edible oil by producing brown rice oil by extracting the oil contained in rice gangue produce a considerable amount of brown rice oil.

Thus, until now, rice husks have been mixed with rice bran in the process of rice cultivation and have been used for feed or preservation. However, various nutritional ingredients including vitamin E contained in rice have been confirmed, and attempts have been made to use them as raw materials for food processing or for food.

The major components of rice are starch 90%, rice 20%, protein 15%, starch 16%, rice 21.6%, protein 20.2%, starch 2.4%, and vitamin content Is high and good value as food raw material. However, rice blend mixed with rice bran easily deteriorates quality due to the rancidity of rice bran. It is difficult to separate rice bran from rice bran. .

However, Korean Patent Laid-Open Publication Nos. 1998-23071 and 1998-23072 disclose methods for producing beverages using rice gruel even in the above-mentioned difficulties, and methods for producing food additives from rice bran and rice husks. No. 97-25422, there is a continuing research on foods to be edible using rice gruel, and a method or apparatus for easily extracting rice gruel from rice gruel is required.

Korean Patent Laid-Open No. 10-2005-0091977 accordingly relates to a method for processing rice bran. The method comprises cutting rice bran as a raw material to a size of 24 to 28 meshes, separating the embryo containing the rice husks and the rice gruel, A primary separation step for obtaining a primary separation mixture in which rice bran rice flour is mixed, a secondary separation step for separating pure rice bran and rice flour by sieving the primary separation mixture into 35 to 42 meshes, The embryo and the rice containing the embryo are removed by wind power to obtain a mixture of the embryo and the rice, the embryo is obtained by the heat treatment to obtain the embryo, the pure rice obtained by the heat treatment of the pure rice obtained in the second separation step, The rice gum rice flour obtained in the obtaining step and the secondary separation step was dispersed in water and then dried to obtain rice rice flour It comprises the processes rice flour obtained.

However, the method disclosed in the above patent has a limitation in selecting high quality rice husks because it is not possible to sort out rice blades having a low quality due to searing or corruption of rice bran during the process of obtaining rice husk (embryo) There is a problem that the purity of the rice grain is deteriorated by containing a lot of fine impurities which are not separated by filtering the impurities.

For example, Patent Document 1 below discloses a rice grain sorting apparatus.
