Solvent Extraction Plant in Gujarat


Gujarat gives an extraction plant three distinct raw materials and each one wants a different machine. Saurashtra, around Rajkot, Junagadh, Gondal, Amreli and Porbandar, is groundnut country, and most of what reaches an extraction unit is expeller cake still holding 6 to 10 percent oil. The Kadi, Mehsana and Kalol belt runs cottonseed at scale. North Gujarat, around Deesa, Palanpur, Patan and Siddhpur, is the largest castor growing region in the world, and castor cake behaves like nothing else in an extractor bed.

As a solvent extraction plant manufacturer in Gujarat, Mecha Engineering designs around the material you actually receive rather than a catalogue model. Oil content, bulk density, moisture and bed behaviour decide the preparatory section, the extractor type and the steam load. Design, fabrication, structural work and shop assembly all happen at our own Saharanpur works, so one engineering team stays answerable from the drawing to the first tonne of meal.

  • 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 Rajkot, Kadi or Deesa 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 Gujarat 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 Gujarat Processors:


Pick the line that matches your feed material, or send your material analysis and we will tell you which of these fits.

Groundnut Cake Extraction Plant

Cake breaking, sizing and conditioning to pull the remaining 6 to 10 percent oil out of expeller cake. The standard build for the Saurashtra expeller belt around Rajkot, Gondal and Junagadh.

Cottonseed Extraction Plant

Delinting, dehulling, conditioning and flaking ahead of a continuous extractor, sized for the volumes handled around Kadi, Mehsana, Kalol and Bhavnagar.

Castor Seed Extraction Plant

Built for the bed behaviour and handling that castor demands, with a DT arrangement that protects the meal, for the Deesa, Palanpur, Patan and Siddhpur belt.

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, sesame 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 spent bleaching earth, which matters for the large refining cluster around Kandla, Gandhidham and Ahmedabad.

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:


Groundnut Oil Mills

Saurashtra expeller groups recovering the oil left in cake, usually the fastest payback a Gujarat oil mill can make on new capital.

Cottonseed and Ginning Groups

Ginning and crushing units around Kadi and Mehsana converting seed into crude oil and washed cottonseed de-oiled cake for the feed trade.

Castor Processing and Oleochemical Units

North Gujarat castor crushers feeding the derivative, lubricant and oleochemical industry that Gujarat exports from.

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 and Port Crushers

Refining groups near Kandla and Mundra adding captive extraction, or re-extracting spent earth to recover held oil rather than 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.

Questions we are asked

Solvent Extraction Plants in Gujarat: FAQs


Straight answers to what Gujarat buyers ask before and after a site visit.

Who manufactures solvent extraction plants in Gujarat?

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 Gujarat. 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 Gujarat, the rest of India and export markets.

What capacity range can you supply for a Gujarat plant?

Batch type mini plants start at around 10 TPD, and continuous lines are built from 20 TPD up to 500 TPD. In Gujarat most enquiries come from expeller groups adding extraction behind existing crushing capacity, so tell us how much cake your presses already produce each day and we size the extractor to that first, with headroom for a second line later.

Which materials can the plant process?

Groundnut cake, cottonseed, castor seed and cake, sesame cake, soyabean, rice bran, mustard cake and refinery spent bleaching earth. Stainless steel versions handle spice oleoresin and herbal material. Castor in particular behaves differently in a bed from groundnut or cotton, so 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 Gujarat 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 Gujarat 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 Gujarat 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 Gujarat?

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 Saurashtra, Kadi or north Gujarat 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. A specification sheet, layout and price come back within one working day.
