my country's vegetable oil production and processing industry is mainly based on the workshop -style soil production tools.After the founding of New China, the country has gradually established the oil processing machinery industry, and the oil processing industry has developed for a long time.In the 1960s, my country had been able to produce a \"Ninth Five -Year Plan\" oil press.Later, after continuous improvement, the factory 95A, 95B, and ZXLOA, ZXLOB oil press.Now, these small oil press are commonly used oil -making machinery for small oil plants and oilfields.In order to meet the needs of the development of oil -making industrialization, there are 200 types (ZX18), Type 202 (ZX24) snail oil press and hydraulic oil press.Since 1970, the promotion and application of solvents immersion method for oligomes and grease equipment has caused my country's oil and fat production industry to have emerged -secondary changes. It is an efficient chemical extraction method for making oils.Prior to 1980, in terms of oil refining technology and equipment, intermittent production process equipment was the main aspects, and edible vegetable oil products also mainly based on national standard secondary oil and national standard first -level oil.After 1980, with the rapid development of my country's economy, oil refining and continuous development of large -scale production methods have also been developed.Today, plant oil processing and production.It is a full -continuous automatic production line and intermittent production coexist.Edible oil products have gradually shifted to high -grade cooking oil and color tensile oil, harmonious oil, hydrogenated oil, artificial cream, buttering of grease, and other high -grade fat products have also developed greatly.

In order to meet the needs of economic development and the improvement of people's living standards, and to improve the competitiveness of oil and oil processing products in domestic and foreign markets, it is necessary to improve the level of processing technology, improve the quality and quantity of oil products, while doing well.The comprehensive utilization of oil and its processing by -products is mainly the comprehensive utilization of oil cakes and shells from oil refinement.The consumption, feeding and industrial use of protein components in oil cakes, as well as the use of phospholipids and fatty acids, has become an important aspect of oil and fat development and utilization.With the development of science, technology and economy, the number of products in response to the city will continue to increase, so as to fully meet people's needs and better serve humanity.
