Vacuum Tray Dryer in Bihar
Bihar's drying demand comes mostly from food and herbal processing, and both punish a hot air oven. Makhana processors in Darbhanga, Madhubani, Purnia and Katihar need a gentle, controlled cycle that holds pop quality and moisture within spec. Litchi, mango and vegetable pulp units around Muzaffarpur dry heat sensitive powders where colour and aroma decide the grade. The pharma and formulation side at Hajipur, Patna and Bihta dries granules and intermediates under GMP, and chemical units near Begusarai and Barauni finish with solvent wet cake that has to be condensed and recovered rather than vented.
As a vacuum tray dryer manufacturer supplying Bihar, Mecha Engineering builds the chamber around your product rather than around a catalogue number. The dryer uses specially designed hollow shelves through which steam or hot water circulates smoothly, so heat passes into the tray by contact instead of by air movement. Under vacuum the boiling point of the moisture drops sharply, which is what lets a delicate product dry faster and at a far lower temperature. Fabrication, polishing, leak testing and trial runs all happen at our own Saharanpur works before the dryer is loaded for Bihar.
- Utilities matched to the site. Many Bihar units run without a steady boiler, so electric and hot water heated shelf circuits are quoted alongside steam instead of being treated as an exception.
- Leak tested before it ships. Every chamber is held under vacuum on our floor and the hold reading is recorded in your test report.
- Audit ready paperwork. MOC certificates, GA drawings, weld and polish records and IQ or OQ documents go with the dryer.
- Spares held in stock. Door gaskets, silicone seals, trays, sight glasses and vacuum fittings ship the same week you ask.
What you get with every dryer
Four Commitments Behind Each Bihar Installation
These are the points Bihar buyers check before releasing a purchase order, so we put them in writing rather than in a brochure line.
Vacuum Held and Recorded
Chamber, door and every nozzle are leak tested at our Saharanpur shop. The vacuum hold figure goes into your test report before dispatch.
Installation by Our Team
Erection, utility tie-in, vacuum pump and condenser piping, commissioning and operator training at your Bihar site, covered in the supply scope.
Direct Manufacturer Pricing
You buy from the fabricator, not a trading house. No dealer margin, and any design change is quoted against actual material and labour.
Build features
Features of Mecha Engineering Vacuum Tray Dryers:
Every feature below protects one of two things: the quality of the product on the tray, or the hours your operator spends loading and unloading it.
01
Efficient Shelf Heating
Hollow pad type shelves are designed for uniform circulation of steam or hot water, so heat reaches every tray at the same rate and the batch dries evenly from the front row to the back.
02
True Vacuum Operation
Pulling the chamber down drops the boiling point of the moisture, so a heat sensitive product dries at a far lower temperature and the cycle still finishes quicker than an air oven.
03
Leak Proof Chamber
Heavy duty door with a high quality gasket seal, machined door frame and reinforced shell. The chamber holds its vacuum instead of making the pump work for the whole shift.
04
Flat Shelves, Full Contact
Shelves are fabricated and levelled so the tray sits flat on the pad. Contact area is what moves the heat here, and a warped shelf is what causes a wet patch in the middle of a tray.
05
Easy Loading and Unloading
Tray guides, a full width door and comfortable shelf spacing let one operator charge and discharge the dryer with minimal manual handling and no tipping at the edge.
06
Solvent Recovery Built-In
Shell and tube condenser with receiver and vacuum trap where you dry off ethanol, methanol or IPA. Solvent is collected as condensate rather than passing through the pump.

Choosing a model
Which Vacuum Tray Dryer Size Fits your Bihar Batch?
Tray count follows batch weight, and batch weight follows the bulk density of your wet cake. This is the shortlist we work through with a Bihar buyer on the first call.
| Model | Indicative wet load per batch | Heating media usually chosen | Typical Bihar application |
|---|---|---|---|
| 6 Tray | Around 10 to 15 kg | Electric or hot water | R and D and QC laboratories in Patna and Hajipur |
| 12 Tray | Around 25 to 30 kg | Hot water | Pilot scale makhana, litchi and herbal units at Darbhanga and Muzaffarpur |
| 24 Tray | Around 50 to 60 kg | Steam or hot water | Ayurvedic, nutraceutical and food extract production around Patna and Bhagalpur |
| 48 Tray | Around 100 to 120 kg | Steam | Formulation and intermediate drying at Hajipur, Bihta and Fatuha |
| 96 Tray, double door | Around 200 to 250 kg | Steam with a header on both faces | Bulk food, maize and contract processing at Begusarai, Purnia and Katihar |
| Custom build | Quoted to your figure | Steam, thermic fluid or electric | Line matching, retrofit and non-standard tray sizes |
Loads above are indicative only. Actual capacity depends on your bulk density and the cake thickness you can spread on a tray, so share a sample figure and we will confirm the model against it.
How the dryer runs
The Vacuum Drying Cycle, Step by Step
Six stages from wet cake to dry powder. Your operator sees the same sequence on every batch, which is what keeps the moisture figure consistent.
01
Tray Loading
Wet cake is spread on the trays to an even thickness and the trays are slid onto the heating shelves through the front door.
02
Sealing and Evacuation
The door is closed against its gasket and the vacuum pump pulls the chamber down to the set level before heating begins.
03
Heating Through the Shelves
Steam or hot water circulates through the hollow shelves. Heat passes by contact into the tray, so there is no air blast on the product.
04
Moisture Removal at Low Temperature
Under vacuum the moisture boils off well below its normal point, so the product dries quickly without thermal damage.
05
Vapour Condensation and Recovery
Vapour passes into the condenser, is cooled and collects in the receiver. A vacuum trap keeps any carry over out of the pump.
06
Vacuum Break and Unloading
Vacuum is broken through a filtered air line, the door is opened and trays are drawn out for milling, sifting or packing.
Where these dryers are used
Application Areas of Vacuum Tray Dryers:
Pharmaceutical and API Units
Drying of solvent wet cake, intermediates, granules and bulk drug powder where residual solvent has to be condensed and recovered rather than vented.
Herbal and Ayurvedic Processing
Soft extracts, kwath concentrates, oleoresins and shilajit dried gently so that marker compounds and colour survive the cycle.
Nutraceutical and Supplement Makers
Vitamin blends, probiotic and enzyme carriers and standardised extract powders that cannot see high temperature or open air.
Fine and Specialty Chemicals
Dyes, pigments, catalysts and crystalline chemicals that are hygroscopic, oxygen sensitive or prone to degrading in a hot air oven.
Food, Spice and Flavour Plants
Flavour powders, natural colours, spice oleoresins and heat sensitive food ingredients where aroma retention decides the grade.
Contract Manufacturers and Exporters
Multi-product units switching materials weekly, so they buy for quick changeover, easy cleaning and third party audit readiness.

Questions we are asked
Vacuum Tray Dryers in Bihar: FAQs
Straight answers to what Bihar buyers ask before and after a site visit.
Who manufactures the vacuum tray dryers supplied in Bihar?
Mecha Engineering Pvt. Ltd. designs and fabricates vacuum tray dryers at its own works at Village Meharbani on Behat Road, Saharanpur, Uttar Pradesh. The company was set up in 2022 and supplies drying, extraction, blending and process equipment to pharmaceutical, herbal, chemical, food and cosmetic units across Bihar, the rest of India and export markets. You buy from the fabricator, not from a trading house.
What tray sizes and model range can you supply for a Bihar plant?
Standard models run at 6, 12, 24, 48 and 96 trays, and non-standard tray counts are built where a batch size falls between two models. Tell us the wet cake weight you want to dry in one batch and the thickness you can spread on a tray, and we work backwards to the tray count, shelf area and chamber size.
How does a vacuum tray dryer protect a heat sensitive product?
Two ways. Heat comes in by contact through the hollow shelves rather than by hot air blowing across the product, and the vacuum inside the chamber lowers the boiling point of the moisture so it leaves at a much lower temperature. Together they let a delicate herbal extract or API intermediate dry fully without the thermal degradation an air oven would cause.
Which material grade do you use, and can I get certificates?
The standard build uses SS 304 for the chamber interior, shelves and trays. SS 316 and SS 316L are used where the product or solvent is corrosive, or where a pharma audit requires it. Mill test certificates for every plate and pipe are issued in your company name and handed over with the dryer along with the GA drawing and test report.
Do I need a condenser and receiver with the dryer?
If your cake is only water wet, a condenser is often skipped to save cost. If it carries ethanol, methanol, IPA, acetone or any other solvent, order the condenser, receiver, cooling coil and vacuum trap. It recovers the solvent as condensate, keeps vapour out of the vacuum pump and stops you venting solvent into the shed.
What heating media can the shelves take?
Steam and hot water are the usual choice, and hot water suits the lower temperature food and makhana work that most Bihar buyers run. Thermic fluid is used where a higher shelf temperature is needed, and electric heating is offered on 6 and 12 tray lab models where no boiler is available. Tell us the utility you already have and we build the shelf circuit around it.
Is installation and commissioning included for Bihar sites?
Erection, utility tie-in, vacuum pump and condenser piping, leak check, first product batch and operator training at your Bihar site are part of the supply scope. Our engineers travel from Saharanpur and stay on site until the first batch is signed off, so a single planned visit covers installation, trial and operator training.
What documentation is provided for GMP, WHO or export audits?
Standard handover covers the general arrangement drawing, material of construction certificates, vacuum and leak 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.
How long does delivery take, and what about freight to Bihar?
Standard 6 to 48 tray models are built in 4 to 8 weeks from order confirmation and a 96 tray double door or fully automated unit takes 8 to 10 weeks. Road transit from Saharanpur to Bihar adds roughly 2 to 3 days. Freight is quoted at actual cost, and for larger chambers we arrange the trailer, route survey and unloading crane along with the dispatch.
How do I get a price for my vacuum tray dryer?
Call +91-9084351006 or +91-7500378000, send a WhatsApp message, or email info@mechaengg.com with four details: the product you are drying, the wet cake weight per batch, the solvent or moisture involved and the utility available on your floor.
