Sunflower oil solvent extraction plant

The sunflower oil solvent extraction plant is based on the principle of applying chemical extraction. An organic solvent--n-hexan capable of dissolving oil and fat is used in sunflower oil solvent extraction plant, which is used to spray and soak the oil, so that the oil in the oilseed is dissolved in the solvent and extracted.

Compared with sunflower oil pressing plant, sunflower oil solvent extraction plant has the advantages of high oil yield, low residual oil, low labor intensity, good working environment and good quality oil we can got. Solvent extraction technique is a relatively advanced edible oil production method.

However, for the capacity below 30 tons, Henan Doing Company do not recommend sunflower oil solvent extraction plant. Because sunflower oil solvent extraction plant costs is more than sunflower oil pressing plant.

3. Mixed oil evaperation system: 1# Evaporator, 2# evaporator, Stripper

Condenser and recovery system of sunflower oil solvent extraction plant

4. Condensate recovery system: Evaporating condenser, Stripping condenser, Energy saving exhaust gas recovery device

Edible oil solvent extraction technology is divided into three process structures:

1. Direct leaching method: Oilseeds with a low oil content, directly use this method.

2. Pre-squeezing-leaching method: Oil content more than 30%, the oil seeds should be pressed by edible oil press machine firstly, and then the oilseeds cake with relatively high oil content is sent to edible oil solvent extraction plant, which is a commonly used edible oil-making method at home and abroad. Using sunflower oil solvent extraction plant to make sunflower oil is exactly using this method.

3. Puffing-leaching method: An oil-making method in which the oil is first extruded and then leached, which is an oil-making method that has arisen in the world in the 1990s. It has many advantages such as low investment, low power consumption, good leaching effect, strong ability and short leaching time. It is the future development direction of the edible oil manufacturing industry. Producing rice bran oil must using this method.

The best advantage of edible oil solvent extraction technology is high oil yield. Take sunflower oil solvent extraction plant as an example, the sunflower seeds meal after desolventizing just contain less than 1% oil.

Doing Company has professional engineers studing the sunflower oil solvent extraction technology, and own factory manufacturing sunflower oil solvent extraction machine. Besides, Doing also provide sunflower oil solvent extraction plant installation, commissioning and worker training services.
