Soybean oil refining processing machine
China is the origin of soybeans, with a long history of planting, but compared with corn and rice, the yield per mu of soybean oil is relatively low, which is because of its different composition. The content of protein and fat in soybean is relatively high, and the content of carbohydrate is relatively small, and the opposite is true for rice and corn. Plants need to consume more to synthesize protein and fat, but less to synthesize carbohydrates. Generally speaking, soybeans need to consume more during the growth process, which is the reason for the lower yield per mu.
In addition, soybean production is also related to geographical location, climate environment, planting management and so on. In China, soybeans are mainly used in oil production, extraction of soybean protein, and processing into soybean products. With the improvement of living standards, the public's demand for soybean oil has increased, and domestic soybean production is difficult to be self-sufficient, and it has begun to rely on imported soybeans. The domestic demand for soybean oil has increased year by year. For the pressure brought by the shortage of soybeans in my country, all walks of life Improve the comprehensive utilization of soybean raw materials.
Soybean oil is one of the main edible oils in China. There are countless soybean oil production and processing factories. Generally speaking, in order to improve the oil yield of soybean oil and completely retain the stability of soybean protein, most oil factories use leaching method to extract soybean oil. Oil extraction by extraction is an oil production process imported from abroad. It has high production efficiency, good environment, low labor intensity and high cake quality, and is well utilized both at home and abroad. Extracted crude soybean oil contains a small amount of solvents and various common oil impurities, and needs refining treatment to obtain healthy oil that meets the standards.
The traditional process of continuous refining of soybean oil has been very mature after years of development. It can be mainly divided into several process steps: degumming, deacidification, decolorization, and deodorization. It produces healthy and nutritious oil according to complex physical and chemical properties. However, the traditional refining process will cause In order to improve the refining yield of soybean oil, relevant researchers have optimized the existing process technology in order to improve the soybean oil refining yield due to the high loss of active substances in soybean oil, low yield of refined oil, high production cost, and serious environmental pollution. It can reduce production cost and improve refining yield.
Traditional degumming mostly adopts hydration degumming, which uses the hydrophilicity of phospholipid molecules to add an appropriate amount of warm water to the oil for stirring, so that the colloids can be aggregated and separated by washing and filtering. In modern production, some enterprises have chosen a relatively new degumming process - enzymatic degumming, phospholipase and phospholipid bonds in phospholipids, and the hydrolyzed products are diacylglycerol and phosphate, which can increase the yield of finished oil and have higher economic benefits Superior to the traditional degumming process.
In the comprehensive process of alkali refining and deacidification, for the soapstock with high quality crude oil, under the processing of modern science and technology, it is not necessary to carry out the washing process, but to use the adsorbent to absorb and desoap the process. The oil is separated and vacuum-dried to reduce the water content of the desoaped oil to less than 0.3%. The dehydrated oil enters the diatomite mixing tank and mixes with diatomaceous earth, and then pumps it into the blade filter to filter and remove the residual soap and residue in the oil. Phosphorus, the filtered oil enters the decolorization section.
Some domestic enterprises have applied this process in actual production. Although the consumption of diatomaceous earth and white clay and steam consumption have increased slightly, there is no consumption of water washing and discharge of waste water, which reduces power consumption and improves the yield of oil refining. , so that the comprehensive production cost is reduced, the oil quality is increased, and compared with the traditional alkali refining and water washing, the refining yield of soybean oil is improved, and better economic benefits can also be obtained.
Oil deodorization can separate odor molecules in crude oil and improve the oil smoke point and stability. The traditional deodorization process is vacuum deodorization method, which vaporizes odor molecules at high temperature to separate odor. Relevant personnel improved the traditional deodorization vacuum system and chose a dry condensing vacuum system to deodorize grease with a combination of a condenser and a vacuum pump. The condenser generally uses ethylene glycol aqueous solution to condense the condensable gas in the deodorization system. The condensable gas is directly frozen into a solid phase in the dry condenser and attached to the surface of the condenser tube. After passing through the dry condenser, it flows to the vacuum system. Only air remains.
Compared with traditional vacuum deodorization, the steam consumption can be reduced by more than 50%, and it can also capture fatty acids twice. During the deodorization process, vitamin E and sterols in soybean oil will be lost, and the loss rate can reach more than 30%. , the dry condensing vacuum system uses the characteristics of different boiling points of different deodorized distillates to capture the deodorized distillates at different temperatures, and also reduces the amount of fatty acids and oils extracted by the vacuum system. The combination of vitamin E, sterol and other substances can not only be added back to soybean oil to enhance the nutritional value of oil, but also can be sold separately to increase the economic benefits of the oil factory.
