Compared with other oils such as peanuts, sesame, and rapeseed, soybeans have a lower oil content. Therefore, soybeans are usually processed through pretreatment and solvent leaching to obtain soybean oil, which can reduce the residual oil rate and improve Oil yield. Compared with suppression methods. Different oils have different processing techniques. The soybean oil production line includes soybean pretreatment process, soybean oil leaching process and soybean crude oil refining process.

Soybean oil extracted from soybean seeds

In order to extract soybean oil from soybean seeds, the process involves several steps that are critical to successfully obtaining the oil. Extraction of soybean oil can be accomplished by mechanical and chemical methods. These methods can effectively separate oil from soybean seeds and ensure high yields of soybean oil.

Preparation of soybean seeds

Before the extraction process begins, soy seeds need to be thoroughly cleaned to remove any impurities. This ensures the high quality of the resulting soybean oil. The cleaned seeds are then cracked or crushed to break them into smaller pieces, which aids in the extraction process.

Mechanical extraction

Mechanical extraction involves using a screw press to squeeze the oil out of soybean seeds. The crushed soybean seeds are fed into a screw press, where pressure is applied to extract the oil. This method is very efficient and is commonly used for soybean oil extraction on a small to medium scale.

Chemical extraction

Chemical extraction of soybean oil involves using solvents such as hexane to separate the oil from the soybean seeds. The solvent is mixed with crushed soybean seeds to effectively extract the oil. After extraction, the solvent is removed, leaving soybean oil.

Filtration and purification

After soybean oil is extracted, it goes through a filtration process to remove any remaining solids or impurities. The oil is then further purified to ensure its quality before it is prepared for consumption or used in various applications.

Storage of soybean oil

Extracted soybean oil is stored in suitable containers away from direct sunlight and heat to maintain its freshness and quality. Proper storage conditions help extend the shelf life of soybean oil.

Overall, extracting soybean oil from soybean seeds involves a series of steps that are essential to obtain high-quality oil for various purposes.
