Solvent Extraction Plant in Uttarakhand
Uttarakhand is the state closest to our works, and it happens to have two of the cleanest extraction opportunities in north India. The Tarai belt across Udham Singh Nagar, from Rudrapur and Kashipur through Kichha, Bazpur, Gadarpur and Sitarganj, is dense rice milling country, and the bran those mills generate is the natural feed for an extraction plant sitting alongside them. Haridwar and Roorkee add mustard and a steady flow of expeller cake.
The second opportunity is different in kind. Haridwar, Dehradun and Rishikesh form one of the largest ayurvedic and herbal manufacturing clusters in the country, where the requirement is not hexane at all but stainless steel batteries running ethanol or IPA for botanical and aromatic extracts. As a solvent extraction plant manufacturer in Uttarakhand, Mecha Engineering builds both, and our Saharanpur works is under an hour from Roorkee.
- We are next door. Saharanpur to Roorkee is under an hour and Haridwar barely more, so site visits, erection support, commissioning and a spares delivery in Uttarakhand happen quickly rather than being scheduled around a long trip.
- 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.

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
Tarai milling groups converting bran they currently sell cheap into crude rice bran oil and de-oiled rice bran for the feed trade.
Ayurvedic and Herbal Manufacturers
Haridwar and Dehradun units running stainless steel solvent batteries for standardised botanical extracts, where food grade build and clean changeover are required.
Mustard and Edible Oil Mills
Expeller units recovering the oil that mechanical pressing leaves behind in cake, usually the fastest payback a small 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.
Aromatic and Essential Oil Processors
Units working with medicinal and aromatic crops, where solvent extraction sits alongside distillation rather than replacing it.
SIDCUL Food and Process Industries
Industrial estate units at Haridwar, Pantnagar and Sitarganj adding extraction or recovery capacity within an existing process plant.

Questions we are asked
Solvent Extraction Plants in Uttarakhand: FAQs
Straight answers to what Uttarakhand buyers ask before and after a site visit.
Who manufactures solvent extraction plants in Uttarakhand?
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 Uttarakhand. 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 Uttarakhand, the rest of India and export markets.
What capacity range can you supply for a Uttarakhand plant?
Batch type mini plants start at around 10 TPD, and continuous lines are built from 20 TPD up to 500 TPD. Tarai rice millers usually size against the bran their attached mills generate daily, while the herbal units at Haridwar and Dehradun work in far smaller stainless steel batteries measured in litres rather than tonnes. Tell us which of the two you are and the sizing conversation is quite different.
Which materials can the plant process?
Rice bran, mustard and rapeseed cake, soyabean, mahua, neem and karanja seed, walnut and apricot kernel from the hills, and refinery spent bleaching earth. Stainless steel versions handle botanical, aromatic and oleoresin material for the ayurvedic cluster. 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 Uttarakhand 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 Uttarakhand sites?
Erection, piping tie-in, insulation, utility connection, water and solvent trials, first production run and operator training at your Uttarakhand site are part of the supply scope, along with foundation and civil drawings. Uttarakhand is our nearest market, and an engineer usually reaches a Roorkee, Haridwar or Dehradun site the same day.
How long does delivery take, and what about freight to Uttarakhand?
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 Roorkee or Haridwar is a very short run, and to the Tarai belt still a single day movement, quoted at actual cost with trailer, route survey and unloading crane arranged for large vessels.
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.
