Soybean oil production line
Soybeans are commonly called soybeans, with an oil content of 15.5%-22.7%, and are a common vegetable oil. Soybean oil is in great demand in the market. Therefore, more and more people are interested in soybean oil production, and the demand for soybean oil production equipment is also increasing.

Generally speaking, soybean oil production and customer specific needs will affect the selection of soybean oil production equipment.

If processing 1-10 tons of soybeans per day, the integrated screw press is an economical and cost-effective choice. At the same time, in order to increase the oil output, we will equip a drum wok before pressing to heat the oil to a temperature suitable for pressing. In addition to soybean oil, this production method is also suitable for the production of other edible oils, such as sunflower oil, rapeseed oil, cottonseed oil and so on.

Description of soybean oil extraction process:

Cleaning process: In order to effectively achieve the cleaning effect, the process will be equipped with a high-efficiency vibrating screen to clean up large and small impurities; equipped with a winnowing machine to remove side stones; in order to ensure a good operating environment in the workshop, the process design will be equipped with a system dust removal device and cyclone separation Type dust collector and secondary dust removal system.

　　Crushing process: In order to ensure good softening and rolling effects of soybeans, a crusher is used to break soybeans into small pieces, which can ensure that the rolling and softening reach the set process indicators.

Rolling process: Rolling is to prepare cotton kernels of a certain particle size into thin slices of about 0.3 mm, which can fully destroy the structure of cotton kernels. The purpose is to maximize the grease in the raw materials in the shortest time during the leaching process. After extraction, the residual oil in the meal is less than 1%.

Steaming and frying process: the billet obtained from the rolling mechanism enters the steaming and frying pan. After high temperature and high moisture steaming and frying, the temperature and moisture of the cotton billet are adjusted, and the gossypol is effectively destroyed. Squeezer.

Pre-pressing process: The steamed and fried cooked billets are adjusted by the auxiliary wok, and then enter the press chamber for pressing. The squeezed oil is separated by the oil residue scraper to separate the residue in the oil, and the leaf filter is filtered into the crude oil tank; The pre-pressed cake is transported to the extraction and dephenolization workshop for extraction and dephenolization.

　　 Soybean oil refining process:

　　 Soybean oil degumming and hydration

　　The colloidal impurities in crude oil are mainly phosphorus. The presence of gelatinous substances such as phospholipids not only reduces the quality of the oil, but also promotes transitional emulsification between the fat and the lye during the alkali refining and deacidification process, which increases the difficulty of separation of the saponins and increases the loss of neutral oil. Therefore, it should be removed first.

　　 soybean oil deacidification

　　 Oil deacidification is mainly to remove free fatty acids in crude oil, as well as a small amount of colloids, pigments and trace metals in the oil. Deacidification operation is one of the important factors that directly affect the yield and quality of oil refining. The most widely used in industrial production is alkali refining and deacidification.

　　 Soybean oil decolorization

　　The oily color and some other impurities must be decolorized to reach the product quality standard. At the same time, it provides more favorable conditions for deodorization and refining. Decolorization must meet the final requirements of the product color index; remove related pigments and quantitative metals; further remove residual traces of saponins, phospholipids and other colloidal impurities and certain odor substances in the oil; remove polycyclic aromatic hydrocarbons and residual pesticides; reduce oil quality Oxidation value.

　　 Soybean oil deodorization

　　The purpose of oil deodorization is to remove odor-causing substances in the oil and other substances that are easy to volatilize, improve the smell and color of the oil, and increase the stability of the oil. The peculiar smell of oil, the peculiar smell produced by decolorization, the clam smell produced by the oxidation of oil, etc. In the deodorization stage, these unpleasant odors are required to be sprayed directly into the steam distillation at high vacuum and high temperature to remove them.

If the daily soybean processing capacity is more than 10 tons, a complete soybean oil production line is a more suitable choice. The complete soybean oil production line mainly includes soybean pretreatment equipment, soybean oil extraction equipment and soybean oil refining equipment.

Soybean pretreatment equipment is used to clean up impurities in soybeans. At the same time, the temperature and moisture of soybeans meet the leaching conditions through processing techniques such as crushing, softening, and rolling, so that the leaching efficiency will also be improved.

Due to the relatively low oil content of soybeans (15.5%-22.7%), in order to obtain more oil and achieve considerable economic benefits, soybean leaching methods are generally used to produce soybean oil. The leaching method is mainly to use solvent oil (No. 6 light gasoline) to fully soak the processed soybeans so that the oil in the soybeans is extracted. After leaching, the residual oil ratio in the cake is generally less than 1%. Cakes can also be used to process animal feed.

Soybean oil refining equipment is used to process the leached crude soybean oil. Through the degumming, deacidification, decolorization and deodorization sections, harmful and useless substances in crude oil are removed to improve the storage stability of soybean oil and make the color and smell of the oil meet the standards of edible oil.

In terms of specific needs, if the soybean is processed to obtain protein and further process the protein, our engineers can also design the process according to the demand without destroying the protein in the soybean.
