A large body of research has been conducted on the solvent extraction process using various solvents, and it has ultimately been found that hexane is the most suitable, economical, and easily recyclable solvent for any Solvent Extraction Plant or oil milling plant setup.
Solvent extraction is a process technology used to extract oils and oleo compounds from oil-bearing materials. Considering various practical aspects, it has proven effective for extracting oil from low oil-bearing materials to levels below 1%, leaving behind protein-rich meal suitable for applications such as poultry, fish, animal feed, and pet food. Over time, various types of extractors have been designed for this purpose, including the Ball Mill Extractor, Kennedy Extractor, Rotocell Extractor, Rotary Cell Extractor, and Moving Bed Extractor. As a trusted Solvent Extraction Plant Manufacturer, we offer all major extractor types to suit your oilseed processing needs.
The moving deep bed extractor is widely used with hexane as the solvent for extracting oils from a broad range of oil-bearing materials such as soybeans, cottonseed, sunflower seeds, and oil cakes from groundnut, castor, mustard, safflower, sunflower, shea, as well as materials like cocoa nibs. Proper preparation is essential to make the material suitable for extraction. Oil can be extracted from oil-bearing seeds, expelled cakes, or expanded materials.
Moving bed extractors are commonly used with capacities ranging from 60 tons per day to 1000 tons per day to extract oils from various seeds and expelled cakes. Our Solvent Extraction Plant is suitable for Soybean / Soya Bean, Cottonseed, Sunflower Seed, Groundnut / Peanut, Palm Kernel, Sesame Seed, Shea Butter, and Coconut / Copra Solvent Extraction Plant requirements — making it a complete solution for your oil milling plant setup.
Flagship Equipment
Solvent Extractor
Prepared seeds, oil cakes, or expanded materials are conveyed to the extractor through a sealed feeding system with level controls. Inside the moving bed extractor, hexane is sprayed counter-currently over the material, dissolving the oil to form miscella. The miscella is collected, filtered, and sent to a holding tank. The de-oiled material, still containing solvent, is then discharged and conveyed through a sealed system to a desolventizer toaster. This core equipment is central to every Solvent Extraction Plant Process we commission, whether for a Soybean Solvent Extraction Plant, a Coconut Solvent Extraction Plant, or a Shea Butter Solvent Extraction Plant.

Meal Desolventization
The solvent-extracted material is heated in a desolventizer toaster with steam to remove residual solvent, producing de-oiled cake (meal). It is then toasted with controlled moisture to deactivate enzymes and sent for conditioning and bagging.
Solvent vapors and fines are treated in a wet scrubber using hot water, then passed to a condensation system. The process operates in a closed loop, recovering solvent efficiently before final meal handling — a key advantage of our Solvent Extraction Systems.

Miscella Distillation System
Fines-free solvent vapors from the wet scrubber pass through the economizer (shell side), where they transfer heat to filtered miscella flowing in the tube side. The heated miscella is partially vaporized in a flasher, becoming more concentrated, while the vapors are sent for condensation.
The concentrated miscella then moves through a series of evaporators and flashers, where it is progressively heated and concentrated up to about 98%. It is then fed into a vacuum-operated stripping column, where remaining solvent is removed using thin-film exposure. Finally, the oil is dried under vacuum to reduce residual solvent to minimal levels, cooled through a heat recovery and cooling system, and transferred to an intermediate storage tank. This distillation process is an integral part of our complete Solvent Extraction Plant Process, ensuring high-purity oil output across all Solvent Extraction Systems.
