The rice bran oil extraction process is usually solvent extraction. Rice bran has low oil content, and the residual oil rate is high when using the pressing method, rice bran oil is basically not obtained. Therefore, the rice bran oil pressing process is rarely used to extract rice bran oil. So, how is rice bran oil prepared? Huatai Oil Machinery will give you a detailed introduction.
The extraction process of rice bran oil by solvent extraction is divided into three sections: rice bran pretreatment section, rice bran oil solvent extraction section, and rice bran oil refining section.

Introduction to rice bran pretreatment section
In the rice bran pretreatment section, rice bran is prepared for rice bran oil extraction and refining process through the four-step pretreatment process of “bran separation-softening and condition-puffing-drying”.
Fresh rice bran enters the bran separation screen to remove impurities, enters the softening and condition pot to adjust the temperature and moisture of the rice bran, and then enters the rice bran extruder machine and flat dryer successively to obtain rice bran embryos suitable for rice bran oil extraction. The dried rice bran germ can be stored for about a week, which avoids the problem of fresh rice bran becoming rancid after long storage time, and can improve the quality of rice bran oil.

Rice bran oil solvent extraction section
In the rice bran oil solvent extraction process, the rice bran germ obtained from the pretreatment section will be introduced into the rice bran oil extraction system, and react with the organic solvent in the rice bran oil extractor to obtain mixed oil and wet meal. The obtained rice bran mixed oil and wet meal are successively introduced into the mixed oil evaporation system and the wet meal desolventization system for desolventization to obtain rice bran oil, dry meal and organic solvent. The organic solvent obtained from these two processes is recycled and reused through the condensation of the solvent recovery system. The rice bran oil extracted by the solvent extraction process needs to be further refined to remove impurities.

Rice bran oil refining section
The rice bran oil refining section is to remove the fine impurities and solvent residues contained in the extracted rice bran oil. After five steps of degumming, deacidification, decolorization, deodorization and dewaxing, the colloid, fatty acids, pigments, odor substances, etc. in the rice bran oil are removed, and finally the rice bran oil that meets the national edible oil standards is obtained, so that it can be sold in supermarkets.
Rice bran oil refining equipment can be divided into intermittent refining equipment, semi-continuous refining equipment and fully continuous refining equipment according to different processing volumes. You can choose the appropriate equipment configuration plan according to the actual situation.
