what is the role of refined oil equipment in soybean oil production?

Huatai News 2024-01-19 14:16:07

There are two main processing methods for soybean oil: pressing and extraction. The pressing  method is to squeeze out the oil in soybeans through physical pressing, while the extraction method uses chemical solvents to dissolve the oil. Whether it is the pressing method or the extraction method, the crude oil obtained cannot be directly sold as edible oil because it contains many impurities and harmful substances, such as residual solvents, free fatty acids, pigments, etc.In order to remove impurities and harmful substances from the crude oil, it is necessary to refine the soybean crude oil. The refining process mainly includes steps such as degumming, deacidification, dehydration, decolorization, and deodorization. During the refining process, refining oil equipment plays a crucial role.

In the complete set of soybean oil extraction production line, the refining equipment is an important equipment to ensure the quality of soybean oil. The role of refined oil equipment in production is as follows:

Refining and removing impurities

Although the soybean crude oil obtained by extraction has been desolubilized, there will be slight solvent residues. In addition, mechanical impurities generated during production and the phospholipids, free fatty acids and pollution residues of the oil itself are all required. It is removed through refining equipment to improve quality.

Improve color

There are requirements for the color of oil in soybean oil grades. Soybean crude oil needs to remove pigments through refining and decolorization processes to improve the color of soybean oil and obtain soybean oil that has a clear appearance and meets standards.

Removal of odor

The beany smell of soybean oil itself is unacceptable to many consumers. In addition, the burnt or white earthy smell formed during production affects the flavor of edible oil, so this part needs to be removed through the deodorization process of refining equipment. The off flavor makes soybean oil palatable to meet the needs of consumers. Soybean oil itself has a beany smell that is unacceptable to many consumers. In addition, the burnt or white earthy smell formed during production affects the flavor of edible oil. Therefore, it is necessary to remove this part of the soybean oil through the deodorization process of refining equipment to make soybean oil that can meet the taste of consumers.
