Rice bran is by-product obtained from rice mill plant. This is golden reddish cuticle obtained after removal of the husk and during polishing of the rice. The rice bran oil extraction process is a complex process which includes a series of extraction processes.
Rice Bran and Its Structure:

If you want to extract rice bran oil, first,you need to collect enough rice bran. Then you need to know : What is the extraction process of rice bran oil ? How is Rice Bran Oil made? How to extract oil from rice bran? As a professional manufacturer of rice bran oil extraction machine, i will introduce the rice bran oil extraction process to you.
What is the extraction process of rice bran oil ? How is Rice Bran Oil made? How to extract oil from rice bran? Generally speaking the rice bran oil extraction process consists of rice bran pretreatment process, rice bran oil solvent extraction process, rice bran oil refinery process and rice bran oil dewaxing process.

What is the extraction process of rice bran oil ? How is Rice Bran Oil made? How to extract oil from rice bran? For this questions, you will find answer from the following introduce:
First stage: Rice bran oil pretreatment process:

A: Cleaning machine:
Using a variety of equipment to separate the impurities of oilseeds. Main steps: Screening, Magnetic separation, Specific gravity stoner, etc.
B:Rice bran extrusion machine:
After extrusion and puffing, oil seeds cells are damaged completely , the grease evenly spread and cohesion , formed into a strong and mature embryos, improve dissolved permeability, greatly improving the efficiency of oil extraction , increased production capacity.
After rice bran oil pretreatment process, the rice bran flakes will be sent to rice bran oil solvent extarction plant to extract rice bran oil.
Second stage: Rice bran oil extarction process:

Rice bran oil solvent extraction plant is similar with other edible oil solvent extraction plant, including solvent extraction, desolventizer toaster, oil stripping, and solvent recovery.
Solvent extraction is a method for separating a substance from one or more others by using a solvent. The purpose of rice bran oil solvent extraction plant is extract oil from the cake. This rice bran oil solvent extraction method is for larger capacity . After rice bran oil solvent extarction plant , the residual oil rate will be less than 1%。
Third stage: Rice bran oil refinery process and rice bran oil dewaxing process:
Rice bran oil refinery process flow chart
Same with other edible oil refinery plant, rice bran oil refinery process includes degumming, deacidification, decolorization, and deodorization sections. What is different is rice bran oil need dewaxing section, because the wax content in rice bran oil is high, about 3% - 5%. In order to get high quality rice bran oil, the rice bran oil dewaxing process is necessary.
The above is a brief introduction of rice bran oil extarction process, if you want to know more information about rice bran oil extarction process, how to made rice bran oil ? how to extract oil from rice bran?
