What is the principle of solvent extraction process for edible oil processing?

Solvent extraction process is another method for edible oil processing, which is by taking advantage of the principle of oil fat and the organic solvent to dissolve each other to get miscella, and then seperating the crude oil from miscella. In edible oil processing factory, usually use n-hexane to react with processed oil seeds or cakes to extract crude oil out.

The introduction of edible oil solvent extraction plant

Why do we use solvent extraction process for edible oil processing? Solvent extraction process can reduce the oil residue in maximum. That also means we can extract more oil from oil seeds. Because the oil residue will be lower than 1%. And at the same time, the meal is more suitable for animal feed, because of low oil content.

The solvent extraction process can apply to soybean oil, peanut oil, sunflower oil, canola oil, rice bran oil and other edible oil processing. Henan Doing Company can provide 30-2000T/D edible oil solvent extraction plant design, manufacturing, installation and commissioning services.

The edible oil solvent extraction process flow chart

Main process of edible oil solvent extraction process:

Solvent extraction system→ D.T.D.C system→ Miscella evaporation system→ Condenser & Recovery system

Before this, the oil seeds should be processed ahead by oil seeds pretreatment machines. What's more, like peanut, sunflower seeds and canola seeds, they has high oil content, so they need prepressing before into solvent extraction plant. Henan Doing Company will according to your oil seeds to design the edible oil processing plant and solvent extraction plant. Don't hesitate, contact us!
