Soybean oil extraction production line
There are four main sections in the soybean oil extraction production line. First, soybeans need to be screened to remove impurities, stones, and metal substances. According to the process requirements, crushing, softening, embossing or puffing, drying and other pretreatment sections, after soybean crushing Generally, 4 petals or 6 petals are required, the thickness of the embossing is generally 0.3-0.5 mm, and the moisture content of the material after drying is 6-8%. If the above requirements are met, the oil can be extracted.

The second is the soybean oil extraction section. You can choose a flat-rotation extractor, an annular extractor, a chain box type extractor, etc. You can choose a micro-negative pressure leaching process or a negative pressure evaporative leaching process. If the soybean is processed in the later stage, To produce soy protein concentrate or soy protein isolate, you can also choose soybean low-temperature meal production technology, different processing technology, and configure different models of desolventizing dryers, evaporators and condensers.
   The production temperature of oil extraction is generally 50-55 degrees. According to the requirements of the process and products, the drying temperature is selected between 80 and 120 degrees.
 
Extraction plant and extractor under installation
    1. The ring-shaped extractor is suitable for one-time extraction of oils with low oil content such as soybeans and rice bran! It can also be used for leaching pre-pressed cakes of high oil content oilseeds such as rapeseed, cottonseed and tea seed;
2. The fixed-grid flat-rotating extractor The flat-rotating extractor tends to be large-scaled. According to the characteristics of the large diameter of the flat-rotating extractor, the high material grid, and the large daily processing capacity, the structure of the large-scale extractor is also continuously improved. The most significant improvement is to change the active false bottom to a stainless steel fixed grid. Its structure is simpler, operation failures are reduced, and safe operation rate is improved.
Of course, when the processing volume is small, a batch leaching device can also be selected.
Basic working principle of soybean oil extraction production line
   The soybean raw materials to be processed are initially processed in the pretreatment section: the embryo enters the extractor section, the meal is discharged from the extractor after the oil is extracted, the injection of fresh solvent and the extraction of concentrated mixed oil and other technological operations or batch, continuous, The leaching process that goes through cycles. Continuous leaching: the raw material enters the leaching equipment, the meal is discharged from the leaching device, the injection of fresh solvent and the extraction of concentrated mixed oil are continuous soaking processes. The concentrated mixed oil is sent to the oil refining section
   General soybean oil extraction production line, the by-product of production is soybean meal, which is generally used for animals. For poultry feed, we can adjust the protein content of soybean meal according to the customer's specific requirements, and also adjust the physical properties of the meal according to the type of feed. Such as fish feed, pet feed and so on.
   If the low-temperature meal production process is used to extract the by-product soybean white soybean flakes of oil, the protein content is high, soy protein isolate SPI and soybean protein concentrate SPC can be produced, and soy isoflavones and saponins can be extracted. Low-temperature meal can also process drawing protein and tissue protein.

The third is the soybean oil refining section. If the daily processing volume does not exceed 10 tons of soybean oil, we can choose the intermittent refining process. This process equipment is relatively cheap and uses a chemical refining process, which is slightly more expensive than other processes. If the daily processing volume is 10-30 stages, it is recommended to choose a semi-continuous refining process. The equipment configuration of this process is higher than that of the batch refining process, but the product index after refining is guaranteed.
If the daily processing capacity is more than 30 tons, it is recommended to choose the full continuous physical refining process, continuous physical refining process, equipment processing is relatively high, during the production process, the refining consumption is relatively low, the by-product is fatty acid, and the price is higher.
    According to the different requirements of various manufacturers, soy phospholipids can also be extracted. If you need to extract phospholipids, our company can add phospholipid extraction and phospholipid processing equipment.

The last is the soybean oil filling section, and the suitable filling supporting production line is selected according to the output.
China’s oil and fat equipment industry began to rise in the 1950s, and it has experienced more than 70 years of development. Now my country has become a major oil equipment manufacturing country. This is not only the development trend of the oil equipment industry, but also the common industry of our peers. Responsibility. From an international perspective, my country's successful foreign policy and multilateral attention policy have created excellent conditions for oil extraction equipment products to go global. The quality of grease equipment has been greatly improved. In recent years, with the continuous innovation, development and application of high-precision and cutting-edge processing methods in the oil industry in my country, not only the surface flatness and smoothness of the product can be almost the same as that of foreign leaching equipment, but the internal quality has also been greatly improved.
