Key steps in soybean oil production line

Soybean oil production is a complex process that involves multiple stages of extracting and refining the oil from soybeans. The following are the key steps in a typical soybean oil production line:

1. Preparation and cleaning of soybeans

Receiving and Storage: Soybeans are received and stored in large silos or bins.

Cleaning: Use equipment such as sieves, magnets and stone removers to remove stones, dirt and impurities.

2. Crushing and shelling

Crushing: Crush the washed soybeans into small pieces.

Hulling: Removing the outer hull of soybeans by suction and sieve.

3. Tempering and peeling

Conditioning: The shelled soybeans are heated to soften them and make it easier to extract the oil.

Flaking: Press the soybeans into thin flakes to increase the surface area for oil extraction.

4. Extraction

Solvent extraction: Dissolving the oils and fats in soybeans with a solvent (such as hexane), then separating and recovering the solvent.

Mechanical extraction: An expeller press is used to extract the oil, but it is less efficient than solvent extraction.

5. Desolventization

The solvent in the mixed oil is evaporated and the residual solvent in the soybean flakes is removed.

6. Degumming

Treat the oil with water or steam to remove phospholipids and gums to ensure oil quality.

7. Neutralization

The degummed oil is neutralized with alkali to remove free fatty acids and obtain neutral oil.

8. Bleach

Improve the color and quality of the oil by removing pigments and impurities using bleaching earth or activated carbon.

9. Deodorization

The oil is heated under vacuum to remove volatile compounds that cause odor and taste.

10. Winterization (optional)

Cool and filter the oil to remove waxes that can cause cloudiness at low temperatures.

11. Packaging

The refined oil is filtered and packaged in preparation for distribution and sale.

12. By-products

Produces high-protein soybean meal and lecithin used as a food emulsifier.
