Solvent Extraction Plant Manufacturer in India

A solvent extraction plant recovers oil from oilseeds, cakes and other oil bearing material using a food grade solvent, most commonly hexane. Solvent washes the oil out of a prepared bed, the meal is desolventised and toasted, and the oil and solvent mixture is distilled so the solvent returns to the cycle. It recovers far more oil than pressing alone and leaves under one percent residual oil in the meal.

Pressing squeezes oil out mechanically and leaves 6 to 12 percent of it behind in the cake. Solvent extraction washes that remaining oil out chemically, so total recovery is much higher. The two are not alternatives in most Indian mills, they run in series, with the expeller first and the extraction plant behind it working on the cake.

Batch type mini plants start at around 10 TPD, and continuous lines are built from 20 TPD up to 500 TPD, with parallel lines where staged expansion suits the investment better. Tell us the material you receive each day, and whether it arrives seasonally or through the year, and we size the extractor, boiler and storage against your actual peak rather than an annual average.

Rice bran, soyabean, mustard and rapeseed cake, cottonseed, groundnut and sesame cake, sunflower, safflower, maize germ, castor, mahua, neem, karanja and sal seed, niger, linseed and refinery spent bleaching earth. Stainless steel versions handle spice oleoresin and herbal material. The preparatory section changes completely between materials, which is why we ask for an oil content and moisture report before quoting.

Commercial hexane to IS specification is the standard because it extracts efficiently and recovers easily. Consumption typically runs around 1.5 to 2.5 litres per tonne of material processed. Ethanol, IPA and ethyl acetate are used on stainless steel herbal and oleoresin lines where hexane is not acceptable in the finished product.

A properly prepared and correctly loaded plant leaves under one percent oil in the meal on a dry basis, and 0.5 to 0.7 percent is achievable where the feed goes through an expander. Preparation matters more than the extractor here, which is why we quote the preparatory section and the extractor together rather than separately.

The hexane area is designed as a hazardous zone from the first drawing rather than being made safe later. Vapour recovery, nitrogen blanketing points, flameproof motors, starters and field instruments, bonded earthing across the structure and gas detection are part of the standard scope, and drawings are prepared in the form your statutory and insurance inspections ask for.

Yes. Common jobs are adding a preparatory or expander section ahead of an existing extractor, replacing a worn extractor chain and screen assembly, upgrading a DT to a DTDC, rebuilding the distillation and recovery block to cut steam, and adding a PLC panel to a manually run plant. Send photographs, your current layout and a nameplate reading to start.

Yes, as a single scope. Foundation and civil drawings, structural erection, equipment installation, piping, insulation, utility tie-in, water and solvent trials, first production run and operator training are included. Spares such as chains, slats, wedge wire screens, gaskets, seals and condenser tubes are made at our own works, so there is no import wait on a replacement.

Yes. Plants are fabricated at our Saharanpur works and supplied across India and to export markets. Export consignments are despatched in match-marked, container or trailer sized sections with a complete erection drawing set, and our engineers travel for erection and commissioning.
