Shilajit Extraction Plant in Bihar

Mecha Engineering Pvt. Ltd. designs and fabricates shilajit extraction plants at its own works at Village Meharbani on Behat Road, Saharanpur, Uttar Pradesh, and supplies them across Bihar. The company was set up in 2022 and builds extraction, filtration, drying and process equipment for pharmaceutical, ayurvedic, nutraceutical, food and cosmetic units throughout India and for export.

Two ways. The extraction stage runs as a low temperature aqua process with a PT100 sensor in the liquid and jacket control holding the set point, so the batch never overshoots. The concentration stage is done under vacuum, which lowers the boiling point and takes the water off without the heat load that open evaporation would need. Send a sample and we can run a trial batch before dispatch so you see the retained value on your own material.

Single vessels run from 100 litres for pilot and R and D work up to 5,000 litres for commercial lines, with multi-vessel arrangements where throughput demands it. Tell us the daily raw shilajit quantity you want to process and the output form you sell, and we work backwards to the vessel size and the number of batches per shift.

Yes. Extraction, filtration and vacuum concentration are common to both. Resin is drawn off at the end of concentration at a controlled moisture level, while powder needs a spray dryer added after that stage. Most units start with the resin line and add the dryer once capsule or tablet orders justify it, so we size the concentration stage for that addition from day one.

The standard build uses SS 304 for the shell and product contact parts. SS 316 and SS 316L are used where a pharma or export audit requires it. Mill test certificates for every plate and pipe are issued in your company name and handed over with the plant along with the GA drawing and test report.

It depends on your raw material and your buyer. A clean, well sorted lot going into a domestic ayurvedic formulation may pass on basket and bag filtration alone. A retail resin jar or an export lot usually needs a sparkler or cartridge stage after that, and some buyers ask for a membrane stage. We quote the filtration skid as a separate line item so you can see what each stage costs before you commit to it.

Yes, erection, piping tie-in, utility connection, water trial, the first shilajit batch and operator training at your Bihar site are part of the supply scope. Because the distance from Saharanpur is long, the visit is planned as one continuous block, and the engineer stays until your own operators have run a full batch unaided rather than leaving after a demonstration.

Standard handover covers the general arrangement drawing, material of construction certificates, hydro and vacuum test reports, weld and polish records, the operating and maintenance manual and a spare parts list. DQ, IQ and OQ protocols, along with a validation document set, are prepared on request for GMP and export buyers.

Standard vessels ship in 4 to 8 weeks from order confirmation and full turnkey lines take 10 to 12 weeks. Road transit from Saharanpur to Patna, Muzaffarpur or Bhagalpur adds roughly two to three days. Freight is quoted at actual cost, and for larger vessels we arrange the trailer, route survey, packing and unloading crane along with the dispatch.

Yes. Common jobs include adding a filtration skid to a plant that is only using a basket strainer, adding vacuum concentration to a unit still evaporating in open kettles, replacing an agitator and gearbox, adding a PLC panel to a manual line, and repolishing an internal surface that has lost its finish. Send photographs and a nameplate reading to start.

It can, but it has to be built for it. Unsorted material carries more rock, sand and moisture variation than a graded commercial lot, which means a larger settling allowance, a heavier coarse filtration stage and a wash on the residue so you are not throwing away recoverable value with the marc. Send us a sample and a description of what you typically buy, and we will size the sorting and filtration side against your actual input rather than an ideal one.

Call +91-9084351006 or +91-7500378000, send a WhatsApp message, or email info@mechaengg.com with four details: the raw shilajit grade and source, the batch quantity in kilograms, the output form you want, and whether you need PLC controls and export documentation. A specification sheet and price come back within one working day.
