What is rice bran oil solvent extraction process?

Rice bran oil solvent extraction process is a type of safe and technology advanced cooking oil processing craft on basis of chemical extraction theory. 99% rice bran oil can be extracted from rice bran using such solvent extraction process. Because rice bran has low oil content, almost all the rice bran oil factory adopt rice bran oil solvent extraction process, large output and high economic benefits.

As the above picture shows, the rice bran oil solvent extraction process has four steps: 

1. Rice bran oil extraction

Use solvent to extract rice bran oil in the oil extractor, and get wet meal and mixed oil.

2. Wet meal desolventization

The wet meal will be processed in D.T.D.C system to remove the solvent in the meal and get dry meal, which can be sold to as animal feed.

3. Mixed oil evaporation and stripping

The mixed oil will be processed in 1st and 2nd evaporation machine and stripping tower. And the solvent and the rice bran oil will be separated.

4. Solvent cooling and recycling

Solvent from the D.T.D.C system and 1st and 2nd evaporation machine and stripping tower will be cooled and recycled. And reuse in the next rice bran oil solvent extraction process.

The features of rice bran oil solvent extraction process:

● Multiple selections of extractors are available for rice bran oil solvent extraction process. There are three types of extractor, including rotocel extractor, loop type extractor, and drag chain extractor. Generally, they are chosen depend on the input capacity.

Three types of oil extractor used in rice bran oil solvent extraction plant

● The rice bran oil solvent extraction process is high efficiency. All the process are automated, so production cost and energy consumption are low.

● The rice bran oil solvent extraction process has high oil yield. It can assure less than 1% residual oil rate in meal, and the meal will be better to as animal feed.
