Maybe we all know that there are two methods of producing oil: physical pressing with the help of an oil press and chemical solvent extraction assisted by various chemical additives throughout the production process. Now, the physical pressing method seems to be more popular. Why is this?

First, physical pressing is more environmentally friendly. The chemical solvent extraction method uses food-grade chemical solvent additives to extract oil from oil seeds. Residual chemical substances in the finished oil are inevitable. The physical pressing method relies on the mechanical squeezing of the extracted liquid by the oil press. The entire process is green and environmentally friendly and does not damage the oil or the environment.

Secondly, the physical extraction method has a higher oil yield and lower cost than the traditional extraction method. Today, with the rapid development of science and technology, the technology of physical pressing method has been greatly improved. Especially now, many oil presses adopt multi-stage oil pressing method, which can provide higher and larger oil output at lower cost. .

Finally, with the continuous progress of society, people's quality of life is getting better and better, and their requirements for food are getting higher and higher. They will pay more and more attention to what they are going to consume. Physical pressing is more suitable for special oil products that pursue high quality and natural characteristics, such as cold-pressed olive oil.
