Solvent extraction is the most efficient method for recovering oil from oilseeds and press cakes, achieving yields above 95%. It is the industry standard for processing large volumes of material with minimal residual oil.
In this process, prepared oilseed material is subjected to counter-current extraction with hexane, which dissolves the oil to form miscella. The miscella is separated, distilled and recycled, while the de-oiled meal passes through a desolventiser toaster for solvent recovery and conditioning. Efficient distillation and condensation systems ensure solvent recovery rates of over 95%, making the process economical, reliable and sustainable for high-capacity plants.
Kumar's solvent extraction plants are engineered with specially designed wedge wire screens and optimised miscella flow systems for maximum oil recovery. Desolventiser toasters ensure safe and efficient meal conditioning while achieving high solvent recovery. Distillation units, economisers and hydroclones are integrated for energy savings, consistent operation and reduced maintenance. Robust construction, automation-ready systems and solvent recirculation capabilities make these plants efficient, safe and cost-effective.
