Solvent Extraction Plant in Rajasthan
Rajasthan is the mustard capital of India, and that shapes almost every extraction enquiry that comes out of the state. Bharatpur, Deeg, Kumher and Alwar hold one of the densest expeller clusters anywhere in the country, and what reaches an extraction plant there is cake still carrying 8 to 12 percent oil. Sri Ganganagar and Hanumangarh add a second mustard stream alongside cottonseed from the canal belt.
The rest of the state pulls in different directions. Hadoti, around Kota, Baran, Bundi and Jhalawar, runs soyabean and needs a full flaking line. Bikaner, Nagaur, Churu, Sikar and Jodhpur send groundnut cake and guar korma. As a solvent extraction plant manufacturer in Rajasthan, Mecha Engineering sizes the preparatory section and extractor around which of these you receive, and fabricates the plant at our own Saharanpur works.
- Short road run to eastern Rajasthan. Saharanpur to Alwar, Bharatpur or Jaipur is a direct highway movement, which keeps freight, crane and erection cost predictable for the mustard belt.
- 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.

Extractor drive, conveyors and vessels trial assembled and run at our Saharanpur shop. Hydro and leak tests are recorded before anything is loaded on a trailer.
Turnkey Erection by Our Team
Civil and foundation drawings, structural erection, piping, insulation, utility tie-in, commissioning and operator training at your Rajasthan 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 Rajasthan Processors:
Pick the line that matches your feed material, or send your material analysis and we will tell you which of these fits.
Mustard and Rapeseed Cake Plant
The Rajasthan standard. Cake breaking, sizing and conditioning to pull the remaining 8 to 12 percent oil out of expeller cake, built for the Bharatpur, Deeg, Kumher and Alwar cluster.
Soyabean Extraction Plant
Full preparatory line with cracking rolls, dehuller, conditioner and flaker feeding a continuous extractor, sized for the Hadoti belt around Kota, Baran and Jhalawar.
Groundnut Cake Extraction Plant
Cake breaking and sizing to recover the 6 to 10 percent oil that pressing leaves behind, for the Bikaner, Nagaur, Churu, Sikar and Jodhpur expeller units.
Guar Korma and Churi Line
Handles guar by-product streams from the gum industry, where recovered oil and a cleaner protein-rich meal both add value for the feed and export trade.
Mini and Batch Type Extraction Plant

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:
Mustard Oil Mills and Expeller Groups
Bharatpur and Alwar crushers recovering the oil that pressing leaves in cake, which is usually the fastest payback a Rajasthan oil mill can make.
Soyabean Crushing Units
Hadoti 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.
Guar Gum and Korma Processors
Gum industry groups adding value to korma and churi streams through oil recovery and a cleaner, better-selling protein meal.
Edible Oil Refineries
Refining groups adding captive extraction upstream, or re-extracting spent bleaching earth to recover held oil rather than paying to dispose of it.
Oleochemical and Soap Units
Non-edible seed and residue processing feeding soap, oleochemical and biodiesel production streams.

Questions we are asked
Solvent Extraction Plants in Rajasthan: FAQs
Straight answers to what Rajasthan buyers ask before and after a site visit.
Who manufactures solvent extraction plants in Rajasthan?
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 Rajasthan. 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 Rajasthan, the rest of India and export markets.
What capacity range can you supply for a Rajasthan plant?
Batch type mini plants start at around 10 TPD, and continuous lines are built from 20 TPD up to 500 TPD. In the Bharatpur and Alwar mustard belt most buyers already run expellers, so the practical question is how much cake your presses produce each day. We size the extractor to that, with structure and headers left ready for a second line.
Which materials can the plant process?
Mustard and rapeseed seed and cake, soyabean, groundnut cake, guar korma and churi, cottonseed, taramira, sesame cake, rice bran and refinery spent bleaching earth. Stainless steel versions handle oleoresin and herbal material. The preparatory section changes with the material, 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 Rajasthan 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 Rajasthan sites?
Erection, piping tie-in, insulation, utility connection, water and solvent trials, first production run and operator training at your Rajasthan site are part of the supply scope, along with foundation and civil drawings. Eastern Rajasthan is a short road movement from Saharanpur, which keeps the erection team close and shortens commissioning.
How long does delivery take, and what about freight to Rajasthan?
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. Freight to Alwar, Bharatpur, Jaipur or Kota is a direct highway run quoted at actual cost, and for large vessels we arrange the trailer, route survey and unloading crane.
How do I get a price for my plant?
