The background of the rise of the new hydraulic oil press: The vegetable oil production and processing industry in our country is mainly a hand-workshop-style soil press production tool. Since its new establishment, the oil processing machinery industry has been gradually established, and the oil processing industry has achieved long-term development.
New hydraulic oil press In the 1960s, my country was able to produce a 95-type oil press. Subsequently, after continuous improvement, the 95A, 95B, ZXloa and Zxlob oil presses were successively introduced. Nowadays, these small oil presses are commonly used oil-making machinery in small oil factories and individual industrial and commercial households. In order to meet the needs of the development of large-scale oil production, there are 200 type (Zx18 type), 202 type (Zx24 type) screw-type oil presses and hydraulic oil presses.
Since 1970, the popularization and application of the equipment for preparing fats and oils by solvent leaching method of the new hydraulic oil press has caused tremendous changes in the fat preparation industry in my country. It is a high-efficiency chemical extraction method for the preparation of fats and oils. Before 1980, in terms of oil extraction technology and equipment, it was mainly intermittent production technology and equipment. Edible vegetable oil products were mainly national standard grade two oil and national standard grade one and one oil.
After 1980, with the rapid development of China’s economy, oil extraction technology also developed to a mechanized and continuous mass production method. The new hydraulic oil press is now processing and producing vegetable oil. It is a fully continuous automatic production line and intermittent production coexist. Edible oil products have gradually shifted to cooking oil, salad oil, blended oil, hydrogenated oil, margarine, shortening and other fat production, and there has also been a great development.
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 grease processing products in the domestic and foreign markets, it is necessary to improve the processing technology level and the quality and quantity of grease products. Do a good job in the comprehensive utilization of oil and its processing by-products, mainly from oil refining to the comprehensive utilization of oil cakes and husks.
