Vacuum Tray Dryer for Gentle, Low Temperature Drying
Mecha Engineering Pvt. Ltd. is a Vacuum Tray Dryer Manufacturer in India, building stainless steel vacuum tray dryers for the pharmaceutical, herbal, chemical, and food industries. The vacuum tray dryer, also called a VTD, dries heat sensitive and hygroscopic materials gently at low temperature, so the product keeps its quality.
As a vacuum tray dryer manufacturer based in Saharanpur and supplying across India and to export markets, we build each unit in the tray count and capacity you need, from small lab and pilot sizes to larger production models. Every dryer is built for uniform drying, easy tray handling, and a long service life, and is backed by installation support and spares.
The dryer uses heated shelves through which steam or hot water circulates, and it works under vacuum so moisture boils off at a lower temperature. This protects delicate products and shortens the drying cycle. Contact Mecha Engineering Pvt. Ltd. for a GMP compliant dryer sized to your tray count and capacity.
Features of Our Vacuum Tray Dryer
- Gentle Low Temperature Drying: Vacuum operation lowers the boiling point of moisture, so heat sensitive and hygroscopic products dry without thermal damage.
- Uniform Heat Transfer: Steam or hot water circulates through the shelves, giving even, consistent drying across every tray.
- Stainless Steel Construction: Built in SS 304 or SS 316 contact parts for hygiene, corrosion resistance, and easy cleaning.
- Leak Free Vacuum Chamber: Heavy duty door and quality gasket sealing hold the vacuum and keep the chamber clean.
- Range of Tray Counts: Built in standard sizes so the capacity matches your batch, from small lab units to large production models.
- Easy Loading and Low Maintenance: Simple tray loading and unloading with minimal handling, for a long, low maintenance service life.
How a Vacuum Tray Dryer Works?
The vacuum tray dryer is a box shaped batch dryer with a stack of heated shelves inside a sealed chamber:
- Loading: The wet product is spread on trays, and the trays are placed on the heated shelves inside the chamber.
- Heating: Steam or hot water circulates through the shelves and transfers heat evenly to the trays.
- Vacuum: A vacuum pump lowers the pressure in the chamber, which reduces the boiling point of the moisture so it evaporates at a low temperature.
- Vapour removal: The vapour is drawn off and passed through a condenser, which keeps drying conditions steady and protects the product.
- Unloading: Once the product reaches the target moisture, the vacuum is released and the dried trays are removed.

Frequently Asked Questions About Vacuum Tray Dryer
What is a vacuum tray dryer?
A vacuum tray dryer is a box shaped batch dryer that dries products on trays placed over heated shelves inside a sealed chamber. It works under vacuum, so moisture evaporates at a low temperature and the product is not damaged by heat.
Why dry under vacuum?
Vacuum lowers the boiling point of moisture, so drying happens at a lower temperature. This suits heat sensitive and hygroscopic materials, prevents oxidation, and gives faster, gentler drying.
What tray counts do you offer?
We build vacuum tray dryers in standard sizes such as 6, 12, 24, 48, and 96 trays, and we size the unit to your batch. Share your requirement and we will suggest a suitable model.
What material are your dryers built from?
Product contact parts are built in SS 304 or SS 316 stainless steel to GMP standards for hygiene, corrosion resistance, and a long service life.
What heating medium is used?
Steam, hot water, or thermic fluid circulates through the shelves, selected to suit your product and the available utilities.
Which industries use a vacuum tray dryer?
It is used in the pharmaceutical, herbal, chemical, food, and nutraceutical industries, anywhere heat sensitive material needs gentle drying.
Do you provide installation and after-sales support?
Yes. We provide installation support, spares, and ongoing service.
Do you supply vacuum tray dryers outside India?
Yes. We supply across India and to export markets.
