Solvent Extraction Plants SPECTEC offers continuous solvent extraction plants with latest technologies Mechanical method is the combo of high pressure, high temperature,& high moisture, which causes color fixation, oxidation, hydrolysis. Some seeds like rice bran & soya cannot be handelled by the expellors. Continuous solvent extraction plant does not cause any alteration to the properity of oil and recovers it with the characteristics as where present in the raw material and can handelled all materials. CAPACITY - 50 TPD TO 1000 TPD SPECTEC continuous solvent extraction plant consists of
- Seed preparatory section
- Solvent extraction section
- Distillation section
- Meal desolventising section
- Recuperation section
- Meal conditioning section
SEED PREPARATION Preparation is the process of properly preparing seeds for extraction of oil either by solvent or mechanical method. While a particular seed may contain from 20 % - 50 % oil, the oil is tightly bound within the cell & mechanical action must be taken to either forcefully remove the oil or to make the oil accessible to subsequent solvent extraction. The unit operations typically involved are scaling, cleaning, cracking, conditioning (or cooking ) & flacking. Depending on process & oilseed in question, process drying and hulling may be employed, as may expander and collect dryer/coolers. Solvent extraction process typically uses a flammable solvent, the operation is usually removed from the other facilities, and asses to the controlled area is restricted. Unit operation associated with solvent extraction includes extraction, solvent deistillation & liquid-phase recovery. Solid phase extracted material is desolventized, tosted, dried & cooled prier to meal finishing. Extractor is a countercurrent flow device, the solid material moves in an opposite direction of solvent-oil miscella with an increasing oil concentration. As the material to be extracted enters the unit,it is contacted with miscella at the nearly ful oil concentration. After this first wash,the miscella,containing around 20-30% oil,leaves the extractor for solvent distilition and recovery. After passing through the various washing stages, finally being contacted with fresh solvent and allowed to drain for a brief period, the extracted material, commonly known as white flakes, is removed from extractor and is conveyed to the desolventizing process.
