Edible oil is an indispensable component in people’s daily diet, and the extraction method in its production process directly affects the quality and output of oil products. Among many extraction methods, solvent extraction is widely used because of its high efficiency and economy. The following are the main benefits of solvent extraction of edible oil:

1. Improve the oil yield

Solvent extraction method can fully leach oil from raw materials by using chemical solvents (such as n-hexane). (Which solvents are there in the edible oil solvent extraction plant?)Compared with the traditional mechanical pressing method, solvent extraction can extract the residual oil in raw materials more effectively, thus significantly improving the oil yield. This is particularly important for large-scale production, which can maximize the use of raw materials and reduce wastes

2. High cost-effectiveness

The equipment and technology required by solvent extraction method are relatively mature, with high production efficiency and low unit cost. Because this method can extract more oil, manufacturers can get more products at a lower cost, thus improving economic benefits..

3. Suitable for a variety of raw materials

Solvent extraction method is suitable for many oil crops, such as soybean, peanut, rapeseed and cottonseed. Even raw materials with low oil content can achieve high oil recovery rate through this method. This adaptability makes solvent extraction one of the mainstream processes in the production of various edible oils.

4. The oil quality is stable

Edible oil extracted by solvent extraction is usually refined to remove impurities, pigments and odors, which makes the quality of the final product more stable. In addition, modern technology has been able to ensure that the solvent is completely volatilized in the production process and will not affect the safety of oil products.

5. Environmental protection and sustainability improvement

Although there may be some environmental problems in the initial stage of solvent extraction, with the progress of technology, modern technology has been able to achieve efficient recovery and recycling of solvents, greatly reducing the impact on the environment. This improvement makes solvent extraction more in line with the requirements of sustainable development.

In a word, solvent extraction of edible oil has become one of the important processes in edible oil production because of its high oil yield, low cost, wide application range and stable oil quality. With the further development of science and technology, this method will be continuously optimized in terms of environmental protection and safety, providing people with more high-quality and healthy edible oil products.
