Solvent extraction remains the preferred process for large-capacity oilseed processing, valued for its superior extraction efficiency and low residual oil in meal. It works well for soybeans, rapeseed, cottonseed, sunflower seeds and other common oil-bearing materials.

The full production system integrates seed pretreatment, counter-current extraction, mixed oil evaporation, solvent recovery, as well as meal desolventizing and drying. Process parameters are optimized to cut solvent consumption and heat load. Key sections are equipped with automated monitoring to maintain steady, safe continuous running.

We tailor each layout based on customer capacity, raw material characteristics, plant layout and local regulatory requirements. Our scope covers process engineering, equipment supply, site supervision, commissioning and technical training.

Crude oil from the line can go to subsequent refining sections, while the desolventized meal is available for feed use. This proven solution helps oil processors achieve stable output and better overall returns.
