In the traditional oil processing production line, no matter peanuts, rapeseed, soybeans or cottonseed, the oil cake squeezed by the screw oil press will always have a lot of oil left and cannot be completely extruded. The residual oil rate of conventional mechanical pressing technology is generally maintained at 5% to 10%. Even after secondary pressing, 2% to 5% of oil remains in the cake, and a large number of high-quality oil resources are wasted, which greatly reduces the overall profit space of the factory in the long run.

The emergence of solvent extraction plant perfectly solved the limitation of oil production by mechanical pressing, which can completely squeeze out the residual oil in the cake and make every raw material exert its maximum economic value.

Solvent extraction uses the principle of similar miscibility to extract the pressed cake, which can reduce the residual oil rate of the cake to less than 1%, make up for the shortcomings of the pressing process and significantly improve the oil output. The whole production line runs in closed loop, the solvent can be recycled and the energy consumption can be controlled, which is suitable for continuous production in large and medium-sized oil processing plants.

In addition, the solvent defatted cake has high protein content, few impurities and no residual oil, and can be directly used as high-quality feed raw materials and biomass raw materials, so as to realize the secondary utilization of waste materials, truly achieve zero waste of raw materials, and further broaden the profit channels of factories.

If you have a press production line, you can fully tap the value of oil, reduce waste and improve the overall production efficiency only by supporting solvent extraction equipment. We provide mature and stable complete sets of solvent extraction equipment to help oil processing plants increase income and increase efficiency.
