The problem of solvent loss in edible oil solvent extraction plant has always been the focus of the industry. Solvent extraction is an efficient process for extracting oil, but in the production process, solvent loss will not only increase the production cost, but also may have a certain impact on the environment. Therefore, how to effectively reduce solvent loss has become an urgent problem for edible oil production enterprises.

The solvent loss mainly comes from two aspects: one is the volatilization loss in the process, and the other is the solvent remaining in oil and waste residue. Volatilization loss usually occurs when the solvent is recycled or operated at high temperature, and part of the solvent cannot be recovered due to the volatility of the solvent; The residual loss is closely related to the sealing of process equipment, operating parameters and raw material properties.

In order to reduce solvent loss, the factory can take the following measures: first, strengthen the sealing design of equipment to prevent solvent leakage. Second, optimize process parameters, such as controlling appropriate temperature and pressure conditions, to reduce volatilization loss. In addition, improving the solvent recovery system and improving the recovery efficiency are also important means to reduce the loss. Last, choosing a solvent with low toxicity and volatility can not only reduce the loss, but also reduce the impact on the environment.

Apart from the above measures, regular maintenance of production equipment, training of operators and strengthening of production management are also important guarantees for reducing solvent loss. Through technological innovation and management optimization, the edible oil solvent extraction plant can achieve more environmentally friendly and efficient production goals.
