Extraction of Oil from Soya Beans

Soybean oil extraction

The edible oil produced from soybeans is light, clean, and flavorful. This makes it more popular and loved by many people. Soybean oil is composed of 60% polyunsaturated fat and 24% monounsaturated fat, which combine to form a heart healthy oil. Extracting oil from soybeans can be done through several methods, including commercial, chemical, using hexane, and cold pressing. Refined soybean oil will be the future development direction of the edible oil production industry. Therefore, investing in small or large soybean oil refining and processing plants is a profitable opportunity.

Our common edible oils are produced by large refined oil manufacturers through refining and extracting oil packaging. Therefore, if you want to commercialize your edible soybean oil, you need soybean oil refining equipment. Below is an introduction to the refining process of soybean oil processing plants. If you are interested in establishing your own soybean oil factory, please provide us with your email address so that we can contact you and send you more detailed business information to assist you.

Commercial Extraction of Oil from Soya Beans

In modern society, processing plants extract soybean oil through solvent liquid transfer, clean the soybeans, crush and peel them, and then adjust them into thin sheets before entering the extractor to remove the oil. The commercial or industrial soybean oil extraction system mainly consists of seed cleaning and crushing equipment, softeners, presses and refiners, as well as extruders and drums.

• There is a magnetic separator in the seed cleaner that can remove impurities such as nails, wires, and iron. In cleaner places, the stems and pods have also been removed.
• The cleaned beans are taken to the crusher, where they are crushed and separated from the soybean skins and grains. The beans were broken into about four to eight pieces. The preferred crusher is a hobbing crusher with cutting impact and bending effects, which has low noise and uniform output. Crushing helps increase the surface area of oilseeds. This process is beneficial for the transfer of temperature and humidity during the oil seed softening process, ensuring the softening effect.
• Next step is softened in order to adjust the oil seed moisture and temperature to improve its elasticity for the best condition for the rolling process. The softening temperature is based on the level of moisture in the soybean. If the moisture is ranging from 13%-15% the temperature should be between 70℃-80℃ which takes about 15-30minutes. The commonly used softener is the horizontal softening pot which helps avoid abrasion of scraper and heating layer hence long life. Softening reduces power degree and the sticky roller phenomenon.
• Extruding then takes place where the crushed and rolled soybeans are put into a porous expanded granular material. It requires a high temperature for a short processing time i.e. 110℃-200℃ which lasts between one to three minutes.
• During rolling the oil seed is graduated from a granular level to flake. This helps destroy the cell structure of the oil seed. It also increases the surface area of seeds and shortens the distance of the oil flowing out. Moisture and temperature of the materials should be controlled.
• The flake is then taken for pressing where it is squeezed and pressed and under pressure oil seeps out through the press cage gaps and gathers into oil reservoirs. The oil extracted is then filtered to remove solid particles.
• The oil is then refined, packaged, and transported for sale.

The quality of soybean oil is measured by free fatty acids. The general fat extraction process involves washing, crushing, softening, peeling, and pre pressing soybeans, which are the basic processes in today’s soybean oil processing plants.

Hot selling soybean oil refining equipment

Soybean refining equipment is a key device used to remove impurities from soybean crude oil and improve oil quality. It is widely used in the production of edible oil, industrial oil, and feed oil. According to different production processes and processing requirements, soybean refining equipment can be divided into three types: intermittent, semi continuous, and fully continuous, which are suitable for small, medium, and large refineries, respectively.

With the increasing requirements for environmental protection and energy conservation, soybean refining equipment is developing towards greater efficiency, energy conservation, and environmental protection. For example, the water free refining process reduces water consumption and wastewater discharge, lowering production costs. In addition, the application of automation and intelligent technology has also improved the production efficiency and product quality of equipment.

Soybean refining equipment is a key device for improving the quality and production efficiency of soybean oil. The continuous advancement of its technology and the wide application of its technology provide strong support for the deep processing of soybean oil and the development of high value-added products.

Features of Soybean Oil Presses

• The screw oil press employs screw compression or hydraulic advancement to soften oilseeds through mechanical friction heat generated without additional heating, thereby reducing energy consumption. Compared to traditional high-temperature pressing, energy consumption is reduced by over 40%.
• The oil press applies progressively increasing pressure to the oilseeds through the gradually narrowing chamber, extracting all oil in a single pass. This eliminates repetitive processing steps and enhances efficiency.
• Supports both ambient temperature (10°C-50°C) and high-temperature pressing to accommodate different oilseed characteristics. Low-temperature pressing preserves oil nutrients, while high-temperature pressing accelerates oil extraction. Users can flexibly choose based on their requirements.
• Integrated vacuum pump and oil filtration system enable simultaneous pressing and filtering, removing residues and impurities to achieve oil purity that meets sanitary inspection standards.

Some of the advantages of soybean oil is that it is high in nutrition, it has a light colour and it also does not bubble during frying.Therefore, many oil mills that are doing crude oil extraction can consider adding a small oil refining equipment. After that, it is also a good investment and innovation to transform into a small-scale oil refinery.
