Have you ever wondered how high - quality soybean oil is produced? Today, we'll take you on a journey to explore the entire production process of soybean oil, revealing the secrets behind its high - quality creation.
The first step in soybean oil production is the preparation and cleaning of soybeans. When the soybeans arrive at the production plant, they are full of impurities such as soil, stones, and broken beans. Through advanced cleaning equipment, these impurities are effectively removed. For example, the vibrating screen can separate large impurities, while the air separator can remove light impurities like dust. On average, about 3 - 5% of the initial soybean weight is removed as impurities during this process. This step ensures the purity of the raw materials and lays a solid foundation for the subsequent production.
After cleaning, the soybeans enter the crushing and dehulling stage. Special crushers break the soybeans into smaller pieces, and then the dehulling machine separates the hulls from the cotyledons. Removing the hulls is crucial because they contain a relatively low oil content and can affect the extraction efficiency. Approximately 8 - 10% of the soybean weight is the hulls. Our company uses state - of - the - art dehulling technology, which can achieve a dehulling rate of over 95%, ensuring that most of the oil - rich cotyledons enter the next stage.
The crushed soybeans are then conditioned to adjust their moisture and temperature. This process makes the soybeans more suitable for oil extraction. After conditioning, the soybeans are passed through flaking rolls to form thin flakes. These flakes increase the surface area of the soybeans, facilitating the subsequent extraction process. Studies have shown that well - flaked soybeans can improve the oil extraction efficiency by about 15 - 20%.
Extraction is a key step in soybean oil production. Our company uses a solvent extraction method, where a food - grade solvent is used to dissolve the oil from the soybean flakes. The extraction process is carried out in a closed - loop system, which is not only efficient but also environmentally friendly. On average, about 18 - 22% of the soybean weight can be extracted as crude oil.
After extraction, the crude oil needs to go through a series of refining processes. Desolventizing removes the remaining solvent from the oil. Degumming removes phospholipids and other impurities, improving the clarity of the oil. Neutralization is used to remove free fatty acids, and bleaching uses activated clay to adsorb pigments and other impurities. Deodorization removes unpleasant odors, and winterization ensures that the oil remains clear at low temperatures. Each step is carefully controlled, and our company's advanced equipment and strict quality control system ensure that the final product meets the highest quality standards.
In addition to high - quality soybean oil, our production process also makes full use of by - products. The soybean meal left after oil extraction is a valuable source of protein, which can be used in animal feed. The hulls can be used as biomass fuel or for other industrial purposes. This comprehensive utilization not only reduces waste but also reflects our company's commitment to environmental protection and sustainable development.
In conclusion, the production of high - quality soybean oil is a complex and professional process. Our company strictly controls every step of the production process, using advanced technology and equipment to ensure the quality of the product. We are committed to environmental protection and sustainable development, and we believe that our high - quality soybean oil and professional services will meet your needs.
