Solvent extraction plant is an important part of edible oil processing plant. In the production of edible oil, solvent extraction technology is an efficient and widely used technology, which can extract more oil from oilseeds, improve the utilization rate of raw materials and ensure the quality of products.

The core of solvent extraction process is to use chemical solvent to separate oil from oilseeds. Common solvents include hexane, etc. These solvents have good solubility and stability, and can effectively combine with oils and fats. The whole process usually includes steps such as soaking, separation, evaporation and recovery. In the soaking stage, the oilseed is placed in the solvent, and the oil gradually dissolves; Subsequently, the solid residue is separated from the liquid mixture by separation technology; Finally, the solvent is recovered by evaporation to obtain pure edible oil.

The design and operation of solvent extraction plant need strict technical requirements and safety management. Because the solvent has certain volatility and flammability, the factory must ensure that the equipment is well sealed and equipped with advanced fire and explosion-proof facilities during operation. In addition, the recovery rate of solvent is also an important index to measure the efficiency of the factory. By optimizing the process flow, the solvent loss and production cost can be reduced.

Compared with the traditional pressing method, solvent extraction method has obvious advantages. It can not only extract more oil from raw materials with low oil content, but also maintain the nutritional components and flavor of oil products, and meet the needs of consumers for high-quality edible oil. However, this technology also faces certain challenges, such as environmental protection. Waste gas and waste liquid may be produced in the process of solvent extraction, which has an impact on the environment. Therefore, modern solvent extraction plants are usually equipped with advanced environmental protection equipment to ensure that waste treatment meets the standards.
