    Solvent extraction process of soybean - Edible Oil Expeller

    The first stage is mainly to dissolve the oil in the damaged cells by solvent. The extraction amount is large and the time is short (15~30 minutes), and the total oil content can be extracted from 85% to 90%.In the second stage, solvents are needed to penetrate into the unspoiled cells for a long time with low efficiency.
