Soybean oil is one of the common edible oils in our daily life, and its production process is relatively complicated and needs to go through many steps. The following will briefly introduce the production process of soybean oil.

First of all, the production of soybean oil begins with the selection and cleaning of soybeans. High-quality soybeans determine the quality of the final product, so it is necessary to pay attention to its maturity and oil content when choosing soybeans. The selected soybeans will be washed to remove impurities and dust.

Followed by crushing, softening and flaking. The washed soybean is sent to a crusher for crushing, then softened in a softening pot, and then pressed into thin slices by a flaker. This process is helpful to improve the subsequent leaching efficiency.

Then, cooking is carried out to further improve the oil yield of soybeans.

Next, there is the oil pressing stage, and you can choose the pressing process or the leaching process, which is one of the core steps of soybean oil production. The rolled soybean flakes are sent to a extractor, and the oil is separated from the solid matter by using an organic solvent (such as hexane). This process needs to be carried out under specific temperature and pressure conditions to ensure the maximum extraction of oil.

The mixture after leaching needs to be evaporated and desolventized to remove the residual solvent. The evaporator separates the solvent from the oil, and the desolventizing tower further purifies the oil to make it reach the edible standard.

Finally, the extracted crude oil needs to be refined. The refining process includes degumming, deacidification, decoloration and deodorization. These steps are aimed at removing impurities, free fatty acids, pigments and peculiar smell from oil, and making soybean oil more pure and stable.

After these steps, the obtained soybean oil can be filled and packaged to become a finished product sold in the market. Soybean oil is welcomed by consumers because of its rich unsaturated fatty acid content, and it is an ideal choice for cooking and eating.

In a word, the production of soybean oil is a highly technical process, and every link needs to be strictly controlled to ensure the quality and safety of the final product.
