Vegetable oil solvent extraction plant uses n-hexan to extract oil from oil seeds that has been pretreated. And the oil loss rate can be lower than 1%.

Main Equipment introduction:

1. Solvent pumps: continuously spray solvent to the rotary-typr extractor.

2. Roary extractor: spray and soak the corn germ cake with solvent so that oil fats can be dissolved in solvent (form miscella). After processing, you can get wet meal and miscella (mixed oil).

3. DTDC: used to separate the solvent from the wet meal.

4. Miscella tank 1st: pump the miscella ( oil with solvent) into the miscella 1st, then add 10% saline water to it. The phospholipid and impurities in the miscella will react with the saline water, at last the reactant precipitate, reaching the goal of purifying.

5. Miscella tank 2nd: the purified miscella will be pumped into it.

6. Miscella stripping: it will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling.

7. Condensers: used to cooling the solvent gas separated from the wet meal and miscella for recycling.

Detail information:

1. Degumming and deacidification: 

The gumming is moved by phosphoric acid and hot water. There are two ways to move the acid in the crude oil. One is chemical way, the other one is physical way. The chemical way is using NaOH to react with acid. This way is suitable for the capacity of 5-30T per day. The physical way is using steam and centrifugal to move the acid. This way is used for 30-2000T per day capacity vegetable oil refinery plant.

2. Decolorization: 

This step is used to adjust the color of the oil. You can control the color of the corn germ oil according to the requirement of your market.

3. Deodorization: 

The function of this step is to move the special smell in the oil. This is an important standard for refined crude oil.
