Solvent Extraction, as the name suggests is a process to extract the oil from oil bearing materials by means of Solvent, normally- n – hexane. The plant is designed to extract oil directly from oil seed containing less than 20% oil like soyabean after flaking or it extracts oils from prepressed or fully pressed cake of seeds containing more than 20% oil like sunflower, peanuts, cotton seed, palm kernel, canola, copra, castor and variety of other materials. The extraction is carried out in a long horizontal moving bed that works on counter current, moving bed principal with variable bed height and variable speed mechanism permitting excellent penetration and percolation of solvent for absolute extraction. The low speed of extractor conveyor ensures almost no maintenance. Distillation takes place under vacuum and desolventising of meal is done in liberally designed desolventiser Toaster. For solvent recovery adequate capacity condensors and vent air stripping system is provided.
