Introduction of soybean oil production line

Pretreatment section

Before soybeans enter the soybean oil pressing machine for soybean oil production, they need to go through processes such as cleaning, crushing, softening, flaking, and cooking, which is called soybean pretreatment process. Adequate pretreatment of soybeans can improve the quality and yield of the soybean oil. Usually, the soybean oil pretreatment process is as follows:

Cleaning: In the soybean oil pretreatment process, we need to use some cleaning machines such as

magnetic selectors, de-stonner and magnetic selector. These cleaning machines can help remove some impurities such as leaves, stones, sand, dirt, spoiled seeds and metal contaminants.

Crushing: This process requires a crusher to break the soybeans into small particles.

Flaking: The purpose of flaking is to increase the contact area between the soybeans and the roaster and destroy the internal structure of the soybean cells, so as to facilitate the soybean oil pressing machine to press the soybeans.

Cooking: In this process, we need to use a roaster to steam and fry the soybeans after flaking, which can adjust the temperature and moisture of soybeans, as well as achieve the best condition.

After that, we can send the prepared soybeans to the soybean oil pressing machine to squeeze out soybean oil.

Pressing section

The soybean oil production by pressing method is to extract the soybean oil directly from the oilseed by mechanical pressing. The whole process does not contain any chemical additives, ensuring that the product is safe, hygienic, pollution-free, and the natural nutrition is not destroyed. In addition, this process requires the use of a soybean oil pressing machine. Henan Glory Company’s soybean oil pressing machine not only has low energy consumption and small footprint, but also has a low residual oil rate, making it the first choice for soybean oil production machines.

Solvent extraction section

The soybean cake produced by the pressing process contains residual soybean oil, which can be extracted by solvent extraction process. The process refers to the use of the miscibility of organic solvents (n-hexane) and oils to extract soybean oil based on the different boiling points of organic solvents and soybean oil. After solvent extraction, the residual oil content in soybean cake is less than 1%. This method is widely used in large-scale commercial operations due to its efficiency. If you want a higher profit or higher processing capacity, you can choose this method. The processing capacity of our soybean oil solvent extraction plant is from 20 tons to 100 tons per day. The main machines used in this part include extractor, stripping tower, evaporator, oil-water separator, condenser, stripping tower, etc.

Refining section

Whether soybean oil is produced by pressing method or solvent extraction method, what we ultimately get is crude soybean oil. This process is used to remove colloidal impurities, free fatty acids, pigments and odors in crude soybean oil. The machines required for the soybean oil refining process includes refining pots, decolorizing pots, deodorizing pots, filters, etc. In this regard, Henan Glory Company can provide intermittent, semi-continuous and fully continuous soybean oil refining machines. Besides, we can also match the appropriate soybean oil refining machines for the customer according to the processing capacity of the soybean oil production plant.

The above are the sections and machines involved in the soybean oil production line, but machines are not fixed. Henan Glory Company can increase or decrease the machines according to the processing capacity and detailed requirements of different customers’ soybean oil production plants, while ensuring the output efficiency of oil products, and ensuring greater benefits with less investment cost. If you want to know which soybean oil production machine corresponds to different processing capacities, please consult Henan Glory Company.
