Extraction method: Rotary extractor It uses extraction, and selects an organic solvent which can dissolve the oil, after contact with the pre - treated oil by spray or immersion so that the oil can be extracted. Since the boiling point of the solvent and the oil, after evaporation and boil-off Bosni the solvent is evaporated, and we can get crude oil. Ring extractor It adopts the chain transmission system, it is suitable for pre-pressing of the seeds with high oil content and extraction of seeds with low oil content. Like rotary extractor, the design of extractor is designed to reduce energy consumption, maintenance requirements and noise. Line refining 1. Degumming: to Remove phosphate by adding hot water when the phosphate encounters hot water, it will become more and more, and then deliver tanks. 2. Removal of acidity: Remove the FFA by add caustic soda (for neutralization). 3. The discoloration. Delete the segment by adding bleaching earth and the remaining bleaching earth will be filtrated by leaf filter. 4. Deodorization: Remove the oxide, solid particles, and vaporizing the gas.
