Rice bran is a byproduct of rice processing, accounting for about 7% of the total weight of rice. It is a significant byproduct during the rice milling process. Although rice bran oil only accounts for 7% of the weight of rice, its oil content is as high as 18% to 20%. Industrially, rice bran oil is mainly produced through pressing and extraction. Rice bran oil pressing has the advantages of good nutrient retention and no chemical residue, making it popular with consumers. However, pressing leaves 8%-14% of usable oil in the rice bran meal, resulting in a waste of oil resources. Chemical rice bran oil extraction method, on the other hand, can fully extract the oil from rice bran, achieving a higher oil yield. Therefore, extraction is generally used in industrial production to extract rice bran oil.
The rice bran oil extraction process involves dissolving and extracting the oil with an organic solvent to form a mixed oil. Subsequent processes such as evaporation, stripping, and condensation are then used to separate and recover the solvent, yielding crude extracted rice bran oil. The commonly chosen solvent for rice bran oil extraction is n-hexane, which has good solubility and high solvent recovery rate. However, the use of chemical solvents can lead to poor oil color and residue in the oil. Therefore, the extracted oil needs to be refined before it can be consumed. Rice bran oil refining equipment is an indispensable part of the rice bran oil extraction production line.

In summary, the advantages of rice bran oil solvent extraction method lie in efficiency and oil yield. Rice bran oil mills using solvent extraction to process rice bran oil need to consider factors such as investment costs, site selection, and equipment selection.
