Solvent Extraction Plant in Maharashtra
Maharashtra is the one state where a solvent extraction plant has to be good at two very different things at once. Marathwada, around Latur, Nanded, Jalna and Beed, runs on soyabean and needs a full preparatory line with cracking, dehulling and flaking. Vidarbha and Khandesh, around Akola, Amravati, Yavatmal, Buldhana and Jalgaon, run on cottonseed and expeller cake, where delinting, dehulling and cake sizing decide whether the bed drains at all.
As a solvent extraction plant manufacturer in Maharashtra, Mecha Engineering sizes the plant around the material your mandi actually delivers, not a catalogue model. Soya arrives for a few intense months and cottonseed runs longer, so extractor loading, boiler sizing and storage are drawn against your real crushing calendar. Design, fabrication and shop assembly happen at our own Saharanpur works before anything is despatched to site.
- Despatch built for the distance. Plants leave Saharanpur in match-marked, trailer-sized sections with an erection drawing set, so nothing is cut or improvised on your Latur or Akola 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.

Turnkey Erection by Our Team
Civil and foundation drawings, structural erection, piping, insulation, utility tie-in, commissioning and operator training at your Maharashtra site, covered in the scope.
Direct Manufacturer Pricing
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.
Systems we supply
Solvent Extraction Plant Range for Maharashtra Processors:
Pick the line that matches your feed material, or send your material analysis and we will tell you which of these fits.
Soyabean Solvent Extraction Plant
Full preparatory line with cracking rolls, dehuller, conditioner and flaker feeding a continuous extractor, with a DTDC where feed grade soya DOC is the product. The standard build for Latur, Nanded and Jalna.
Cottonseed Extraction Plant
Delinting, dehulling and cake sizing ahead of the extractor, sized for the expeller belt of Akola, Amravati, Yavatmal and Jalgaon where cake still carries useful oil.
Groundnut and Sunflower Cake Plant
Cake breaking, sizing and conditioning to recover the 6 to 10 percent oil that mechanical pressing leaves behind in groundnut and sunflower cake.
Mini and Batch Type Extraction Plant
Batch percolation extractors for 10 to 30 TPD duty, lower capital and simpler operation. A practical first plant for a miller moving from expeller-only to solvent extraction.
Oleoresin and Herbal Extraction Line
Stainless steel batteries running ethanol, hexane, IPA or ethyl acetate for spice oleoresin, safflower and botanical extract duty, with vacuum concentration on the outlet.
Spent Earth and Re-Extraction Unit
Recovers the 20 to 30 percent oil held in refinery spent bleaching earth and residues, which matters for the refinery cluster around Navi Mumbai, Pune and Nagpur.

|---|---|---|---|
| Soyabean | 18 to 20 percent | Cracking, dehulling, conditioning, flaking | Latur, Nanded, Jalna, Beed, Parbhani |
| Cottonseed | 16 to 20 percent | Delinting, dehulling, conditioning, flaking | Akola, Amravati, Yavatmal, Jalgaon, Dhule |
| Cottonseed Cake | 6 to 10 percent residual | Cake breaking and sizing only | Khandesh and Vidarbha expeller units |
| Groundnut Cake | 6 to 10 percent residual | Cake crushing and sizing | Ahilyanagar, Dharashiv, Solapur |
| Sunflower and Safflower | 20 to 35 percent | Dehulling, conditioning and flaking | Solapur, Dharashiv, Sangli, Satara |
| Rice Bran | 14 to 20 percent | Stabilising, then pelletising or expander | Bhandara, Gondia, Chandrapur, Raigad |

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:
Soyabean Crushing Units
Marathwada crushers converting seed into crude soya oil and the de-oiled cake that carries most of the plant revenue through the poultry trade.
Cottonseed and Ginning Groups
Ginners and expeller units in Vidarbha recovering the oil that pressing leaves in cake, usually the fastest payback a Maharashtra oil mill can make.
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.
Edible Oil Refineries
Refining groups adding captive extraction upstream, or re-extracting spent bleaching earth to recover held oil instead of paying to dispose of it.
Spice, Oleoresin and Herbal Extractors
Stainless steel solvent batteries for oleoresin and botanical extract lines where food grade construction and clean changeover are required.
Oleochemical, Soap and Biodiesel Units
Non-edible seed and residue processing feeding soap, oleochemical and biodiesel production streams across the western belt.

Questions we are asked
Solvent Extraction Plants in Maharashtra: FAQs
Straight answers to what Maharashtra buyers ask before and after a site visit.
Who manufactures solvent extraction plants in Maharashtra?
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 Maharashtra. 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 Maharashtra, the rest of India and export markets.
What capacity range can you supply for a Maharashtra plant?
Batch type mini plants start at around 10 TPD, and continuous lines are built from 20 TPD up to 500 TPD. In Maharashtra the deciding factor is usually the crushing season rather than the annual tonnage, so tell us how many months soyabean or cottonseed actually arrives and we size the extractor and boiler against that peak instead of an average.
Which materials can the plant process?
Soyabean, cottonseed and cottonseed cake, groundnut and sunflower cake, safflower, sesame, rice bran, maize germ and refinery spent bleaching earth. Stainless steel versions handle spice oleoresin and herbal material. The preparatory section changes completely between soya and cottonseed, which is why we ask for an oil content and moisture report 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 Maharashtra 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 Maharashtra 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 Maharashtra 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 Maharashtra?
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 Marathwada, Vidarbha or Khandesh 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?
