Soybean Oil Production Line
A large-scale soybean oil production plant involves several interconnected processes to efficiently extract oil from soybeans and produce high-quality refined soybean oil. The soybean oil production line includes the soybean pretreatment process, soybean pre-pressing process, soybean oil extracting process, and soybean crude oil refining process. Our advanced soybean oil equipment, such as solvent extractors and automatic control systems, ensures high yields and consistent quality of both crude and refined oil. With capacities ranging from 30tpd to 5,000tpd, our soybean oil production plants are perfect for meeting the demands of large-scale edible oil production requirements.
Soybean Oil Production Line Overview
Soybean oil is one of the most widely consumed edible oils globally due to its versatility, high yield, and nutritional value. While, soybean is a low oil content oilseed compared with other oilseeds such as peanut, sesame, and canola. So we adopt soybean pretreatment and solvent extraction methods to process soybean and get soybean oil, which can reduce residue oil rate and increase oil productivity compared with the mechanical pressing method.

Soybean Oil Production Line Working Process
Soybean Pretreatment Process
Before soybean oil pressing, the soybean needs cleaning, crushing, softening, flaking, extrusion, etc., which provides conditions for the next step of soybean oil processing.
Soybean Cleaning Process And Related Machines
The soybean cleaning process is a screening and stone removal process. It is very important for the soybean oil pre-treatment process.
The High-efficiency vibrating screen is adopted here to remove impurities, effectively achieve the cleaning effect, ensure a good operating environment and stability of production, and simultaneously improve the product quality.
Suction-type specific gravity stoner is used to remove hard impurities like mud and stones.
The magnetic selector is applied to remove metal impurities.
A dust remover is equipped in this process, the suction air net system can effectively control the dust of raw materials and ensure the cleanliness of soybean raw materials.
Soybean Crushing Process And Related Machines
The soybean crushing process facilitates the transfer of temperature and moisture during steaming and frying and improves the steaming and frying effect. To achieve a good softening and flaking effect, the soybean needs to be crushed into 4-6 pieces to ensure uniform granularity. Therefore, when softening, the moisture is uniform and thorough. The flake piece is thin but strong when flaking. The common cracking equipment is a roll crusher, hammer crusher, and disc huller.
Soybean Softening Rolling Machines
The horizontal soybean softening machine is adopted here to heat the soybean to 50-70℃. Therefore, the plasticity of soybean is increased through adjusting the moisture and temperature, creating good operation conditions for flaking and cooking. The softening process can not only make the flake thin, uniform, and tough but also reduce the nonhydratable phospholipids content in crude oil, which is convenient for the dephosphorization and physical refining of salad oil. Soybean rolling uses the mechanical function to roll the soybean from the granular to the flake.
Soybean Flaking Machines
Flaked Soybean Material Cooking Drying
Generally, the flake made from a flaking roll has a water content of 12%. However, the optimum moisture for the leaching process is 9%, so effective drying is necessary to achieve the best leaching moisture.
Soybean Oil Pressing Process
In soybean oil production, the choice between mechanical pressing and solvent extraction depends on factors like plant capacity, oil yield requirements, production costs, and intended uses of the by-products (oilcake/meal). The mechanical pressing method is usually a good choice for a soybean oil mill plant with a capacity under 100 TPD. For small to medium production scales, when residual oil in the cake is acceptable or desirable, and when producing high-value, premium, or organic oils, we recommend using the mechanical soybean pressing method. The oil press machines have a capacity ranging from 10 to 200 tons per day (TPD), and they can extract about 70% of the oil in the soybean.
