Solvent Extraction Plant in Chhattisgarh
Chhattisgarh mills more rice than almost anywhere in India, and the belt running through Raipur, Durg, Bhilai, Bilaspur, Rajnandgaon, Mahasamund, Dhamtari, Janjgir-Champa and Bemetara throws off bran in quantities that make a captive extraction plant an obvious step. Bran is also a material that punishes delay, because free fatty acid climbs the moment stabilisation slips, and a plant sitting next to the mills protects that value.
South and north of the rice belt the material changes completely. Bastar, Kondagaon, Kanker, Surguja and Jashpur send sal seed, mahua and niger from the forest districts, which are seasonal, collected rather than farmed and variable in moisture. As a solvent extraction plant manufacturer in Chhattisgarh, Mecha Engineering designs for whichever of these you actually handle, and fabricates the plant at our own Saharanpur works.
- Despatch built for the distance. Plants leave Saharanpur in match-marked, trailer-sized sections with a full erection drawing set, so nothing is cut or improvised on your Raipur, Bilaspur or Jagdalpur site.
- Turnkey or section wise. Take the complete line, or only the preparatory section, the extractor, the DT or the distillation and recovery block to upgrade what you already run.
- Safety built into the design. Flameproof motors and panels, proper earthing, nitrogen purging points and vent gas recovery, documented for your statutory approvals.
- Spares without an import wait. Chains, slats, wedge wire screens, gaskets, seals and condenser tubes are made and stocked at our own works.

You buy from the fabricator, not a trading house. No dealer margin, and every design change is quoted against actual material, machining and labour.
Build features
Features of Mecha Engineering Solvent Extraction Plants:
Every feature below protects one of three numbers your plant is judged on: oil recovered, solvent lost and steam burned per tonne.
01
Maximum Oil Recovery Efficiency
Extractor bed depth, sprinkler layout and miscella stage count are matched to your feed so solvent washes the bed evenly. Residual oil in the meal is held to under one percent on a dry basis instead of drifting up with load.
02
Energy Efficient Operation
Economiser, multi-stage evaporation and heat exchange between hot meal, vapour and incoming miscella cut live steam demand. Lower steam and power per tonne is where an extraction plant actually earns its payback.
03
Robust Safety Systems
Vapour recovery, nitrogen blanketing points, flameproof motors, starters and field instruments, bonded earthing and gas detection. The hexane section is treated as a hazardous area from the first drawing, not retrofitted later.
04
Customisable and Scalable Design
Layouts are drawn to your shed height, plot shape and boiler capacity. The structure and utility headers are sized so a second extraction line or a refinery block can be added later without rebuilding.
05
Low Hexane Loss Per Tonne
Shell and tube condensers, a solvent water separator and a mineral oil vent gas absorption column recover solvent that most plants send out of the vent. Hexane is a running cost, so every litre recovered is margin.
06
Feed Grade Meal Protected
Controlled steam sparging and residence time in the desolventiser toaster strip solvent without scorching the meal, so protein and colour hold up and your de-oiled cake sells into the feed trade at the better rate.

How the plant runs
The Solvent Extraction Cycle, Step by Step
Six stages from raw cake to crude oil and de-oiled meal. The solvent runs in a closed loop throughout, which is what keeps hexane cost and fire risk under control.
01
Material Preparation
Feed is cleaned, de-stoned and passed through cracking rolls, a conditioner and a flaker or expander so the oil bearing cells open and the bed drains freely.
02
Extraction With Hexane
Prepared material moves through the extractor while hexane is sprayed counter-current across the bed. Oil dissolves into the solvent and leaves as miscella.
03
Desolventising and Toasting
Wet meal enters the desolventiser toaster, where steam sparging strips residual hexane and toasts the meal to stable moisture and temperature.
04
Miscella Distillation
Miscella is heated through the economiser and evaporation stages, then vacuum stripped so the crude oil leaves free of solvent traces.
05
Solvent Recovery
Vapour condenses in shell and tube condensers and passes to the solvent water separator. Vent gas goes to the absorption column so uncondensed hexane is recovered.
06
Oil and Meal Handling
Crude oil is cooled and pumped to storage or onward to refining. De-oiled cake is dried, cooled and conveyed for bagging or bulk despatch.
Where these plants are used
Application Areas of Solvent Extraction Plants:
Rice Bran Oil Producers
Rice milling groups across the Raipur and Bilaspur belt converting bran they currently sell cheap into crude rice bran oil and de-oiled rice bran.
Sal Fat and CBE Processors
Units extracting sal fat for the cocoa butter equivalent and confectionery trade, where product value justifies careful, gentle processing.
Forest Produce Federations and Collectives
Organisations handling seasonal minor forest produce that want processing capacity near collection rather than shipping seed out of the state.
Soyabean Crushing Units
Rajnandgaon and Kabirdham crushers converting seed into crude soya oil and de-oiled cake for the poultry and cattle feed trade.
Cattle and Poultry Feed Makers
De-oiled cake producers judged on protein, colour and residual solvent, so the desolventiser toaster design matters as much as the extractor.
Oleochemical, Soap and Biodiesel Units
Non-edible seed processing for mahua, karanja and neem, feeding soap, oleochemical and biodiesel production streams.

Questions we are asked
Solvent Extraction Plants in Chhattisgarh: FAQs
Straight answers to what Chhattisgarh buyers ask before and after a site visit.
Who manufactures solvent extraction plants in Chhattisgarh?
Mecha Engineering Pvt. Ltd. designs and fabricates solvent extraction plants at its own works at Village Meharbani on Behat Road, Saharanpur, Uttar Pradesh, and supplies them across Chhattisgarh. The company was set up in 2022 and builds extraction, distillation, drying and process equipment for edible oil, agro-processing, feed, herbal and chemical units in Chhattisgarh, the rest of India and export markets.
What capacity range can you supply for a Chhattisgarh plant?
Batch type mini plants start at around 10 TPD, and continuous lines are built from 20 TPD up to 500 TPD. Most Chhattisgarh enquiries come from rice millers, so the practical question is how many tonnes of bran your mills generate each day. Forest produce units usually need something smaller, because collection is seasonal and a large line idling for months costs more than it earns.
Which materials can the plant process?
Rice bran, sal seed, mahua, karanja and neem seed, niger, linseed, soyabean, sunflower and refinery spent bleaching earth. Stainless steel versions handle oleoresin and herbal material. Forest produce varies far more in moisture and quality than bran from a mill, so we ask for an oil content and moisture report on an actual lot before quoting.
How much residual oil is left in the meal?
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.
What is the hexane consumption and how is loss controlled?
Typical consumption runs around 1.5 to 2.5 litres per tonne of material processed. Loss is controlled by condenser sizing, a properly working solvent water separator, sealed conveyors and a vent gas absorption column that scrubs uncondensed vapour with mineral oil before anything leaves the plant.
What safety arrangements are included?
The hexane area is designed as a hazardous zone from the start. Flameproof motors, starters and field instruments, bonded earthing across the structure, nitrogen purging connections, gas detection points and a vapour recovery loop are part of the standard scope, and drawings are prepared in the form your statutory and insurance inspections in Chhattisgarh ask for.
Can you supply only one section instead of a full plant?
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.
Is installation and commissioning included for Chhattisgarh sites?
Yes, and the scope is the same as for a site next door. Foundation and civil drawings, structural erection, equipment installation, piping, insulation, utility tie-in, water and solvent trials, first production run and operator training at your Chhattisgarh site are included. Our erection team travels to site and stays until the plant is producing to specification.
How long does delivery take, and what about freight to Chhattisgarh?
Mini and batch plants are generally ready in 12 to 16 weeks. Continuous lines take 20 to 30 weeks depending on capacity and automation, with erection running alongside your civil work. Road freight from Saharanpur to Raipur, Bilaspur or Bastar is quoted at actual cost, and for large vessels and structures we arrange the trailer, route survey and unloading crane.
How do I get a price for my plant?
Call +91-9084351006 or +91-7500378000, send a WhatsApp message, or email info@mechaengg.com with four details: the material you will process, the tonnes per day you want to handle, the oil and moisture content of that material and the steam and power available at your site.
