The solvent extraction process of edible oil is a key step to extract oil from various raw materials (such as seeds, nuts and oily crops) with solvents. There are many kinds of solvents in edible oil solvent extraction plant, and the common solvents include: n-hexane, isopropanol, acetone, ethyl acetate.

N-hexane is a colorless liquid solvent with low boiling point and good solubility, which is often used in the extraction of edible oil. It can quickly extract oil components from raw materials, and is easy to separate and recover. It is one of the commonly used solvents in edible oil production.
Isopropanol is another common solvent, which has good volatility and solubility and is suitable for the extraction of some specific components in edible oil. In the extraction process, isopropanol can quickly combine with oil components to form a solution, which is convenient for subsequent separation and purification.
In addition to the above two solvents, acetone, ethyl acetate, methanol and ethanol are also widely used in the extraction process of edible oil. They each have different characteristics and application scope, and suitable solvents can be selected for use according to specific production needs.
In the process of using these solvents to extract edible oil, it is necessary to strictly control the amount and recovery rate of solvents to ensure the safety and environmental protection of products. Moreover, it is necessary to regularly detect and analyze the solvent to ensure that it meets the relevant quality standards and regulatory requirements.
To sum up, the solvents commonly used in edible oil solvent extraction plant include n-hexane, isopropanol, acetone, ethyl acetate, methanol, ethanol and other types, which play an important role in the production of edible oil and provide reliable technical support for the extraction and refining of products.
