Solvent Extraction
his process is related to the extraction of the liquid element from a solid substance, that is, solid - liquid extraction. The oil in the oil cells of the seed is separated using a suitable solvent such as hexane. This separation process is carried out in the extractor, the most important part of the facility. Then, the oil is removed from the oil-solvent mixture by distilling the solvent under light vacuum. The economy of this process is based on the solvent compensated in the mixtures and the bagasse recovered in the extraction with almost no loss. In addition, energy is utilized to the maximum extent possible.
Other important factors are;
Significant fat gain
This is due to the low oil remaining in the bagasse, depending on the equipment design and the countercurrent extraction principle.
