What is a Vacuum Tray Dryer (VTD)?
A Vacuum Tray Dryer (VTD) is a specialised drying solution designed to remove moisture from materials under reduced pressure. This low-pressure environment allows drying at significantly lower temperatures compared to conventional methods, making it ideal for heat-sensitive products.
Featuring a rectangular chamber with multiple trays, the VTD ensures uniform heat distribution and efficient moisture removal. The trays are heated indirectly using steam or hot water, while a vacuum pump creates the necessary pressure reduction to accelerate drying.
Key Features of Vacuum Tray Dryer
Gentle Drying Process
Operates at lower temperatures, protecting heat-sensitive materials from thermal degradation.
Uniform Drying
Ensures consistent drying across all trays, preventing localized overheating or under-drying.
Controlled Atmosphere
Can be used in an inert gas environment, protecting materials from oxidation or contamination.
Reduced Drying Time
Vacuum conditions lower the boiling point of moisture, speeding up the drying process.
Energy Efficiency
Consumes less energy compared to conventional drying methods due to its controlled conditions.
Easy Maintenance
Removable trays and smooth interior surfaces for hassle-free cleaning and maintenance.
Versatile & Customizable
Suitable for drying powders, granules, solids, and delicate heat-sensitive substances in batch mode, with precise control over drying parameters. Available in various configurations — including tray sizes, construction materials, and automation features — to meet specific requirements.
Material of Construction
The Vacuum Tray Dryer is available in MS, SS304, SS316, SS316L, and Hastelloy. Various kinds of fluoropolymer coating on contact surfaces — including Halar, PP, ETFE, PFA, and PVDF — are available for corrosion-sensitive applications. For pharmaceutical GMP applications, SS 316L with internal surface finish Ra ≤ 0.6 µm is standard.
How Does a Vacuum Tray Dryer Work?
A Vacuum Tray Dryer operates by placing wet material on perforated or solid trays inside a rectangular, vacuum-tight chamber. The process steps are:
Loading: Wet material is spread evenly on the trays, which are loaded onto the heated hollow shelves inside the chamber.
Vacuum: A vacuum pump reduces the internal pressure to 25–100 mmHg, lowering the boiling point of moisture.
Heating: Heat is supplied indirectly through steam- or hot-water-heated hollow shelves, allowing drying at 40°C–80°C.
Moisture Removal: The evaporated moisture is drawn out by the vacuum system and condensed, leaving the dried product on the trays.
Unloading: Once the target moisture (LOD) is reached, vacuum is released and the dried trays are removed.

Frequently Asked Questions
What is a Vacuum Tray Dryer (VTD)?
A Vacuum Tray Dryer (VTD) is a drying system that removes moisture from materials under reduced pressure. The low-pressure (vacuum) environment lowers the boiling point of moisture, allowing drying at much lower temperatures (40C to 80C) than conventional dryers. This makes it ideal for heat-sensitive pharmaceutical, chemical, and food products. Material is placed on heated trays inside a vacuum-tight rectangular chamber.
What capacities of Vacuum Tray Dryer does Bipin Pharma manufacture?
Bipin Pharma Equipment manufactures Vacuum Tray Dryers from 12 trays (VTD-12, up to 50 kg/batch) to 96 trays (VTD-96, up to 400 kg/batch), with standard models VTD-12, VTD-24, VTD-48, and VTD-96, plus fully custom configurations. Standard tray size is 700 x 450 mm, with a vacuum level of 25 to 760 mmHg and a temperature range of 40C to 120C.
Why use a Vacuum Tray Dryer for heat-sensitive products?
A Vacuum Tray Dryer is ideal for heat-sensitive products because the vacuum lowers the boiling point of moisture, so drying happens at low temperatures (as low as 40C). This prevents thermal degradation, oxidation, and loss of potency in sensitive APIs, vitamins, and biologicals. It can also operate in an inert gas atmosphere to further protect materials from oxidation or contamination.
What is the material of construction of Bipin Pharma Vacuum Tray Dryer?
Bipin Pharma Vacuum Tray Dryers are available in MS, SS304, SS316, SS316L, and Hastelloy, with SS316L mirror-polished contact parts (Ra under 0.6 micron internal) as standard for pharmaceutical GMP applications. Various fluoropolymer coatings on contact surfaces are also available including Halar, PP, ETFE, PFA, and PVDF. Heating medium options include steam, hot water, or thermic fluid.
