The Vacuum Tray Dryer (VTD) is an essential pharmaceutical processing unit, designed for drying heat-sensitive, solvent-wet, and hygroscopic materials under vacuum conditions. As a leading Vacuum Tray Dryer manufacturer, supplier and exporter in India, Bipin Pharma Equipment has delivered GMP-compliant VTDs to pharma, chemical, food, and cosmetic industries across India and 25+ countries.
What is a Vacuum Tray Dryer?
A Vacuum Tray Dryer is a batch-type, static drying system that operates under reduced pressure. Product is loaded onto stainless steel trays placed on hollow heated shelves inside a sealed double-walled chamber. A vacuum pump draws air out of the chamber, reducing the pressure and consequently lowering the boiling point of moisture or solvents in the product. Heat supplied through hollow shelves via hot water, steam, or thermic fluid gently evaporates moisture at temperatures as low as 30–40°C.
Vacuum Tray Dryer (VTD)
GMP-compliant, SS 316L construction. Available in 4 to 48 tray configurations. Custom sizes available. Exported to 25+ countries.

Agitated Nutsche Filter Dryer (ANFD)
Combined filtration and drying in one closed unit. Ideal for API manufacturing with stringent containment requirements.
View ANFD →Working Principle — Step by Step
- Loading: Product spread uniformly on SS trays in 10–25 mm depth layers
- Chamber Sealing: Door sealed with silicone gasket to ensure vacuum integrity
- Vacuum Creation: Vacuum pump evacuates air; pressure reduced to −0.8 to −1 bar
- Heat Application: Heating medium circulates through hollow shelves — conductive transfer to product
- Evaporation: At reduced pressure, moisture/solvent boiling point drops; evaporation occurs at 30–50°C
- Vapour Removal: Vapour drawn to condenser — solvent recovery possible (IPA, acetone, ethanol, etc.)
- LOD Monitoring: Periodic sampling until target Loss on Drying is achieved
- Venting & Discharge: Vacuum released with dry filtered nitrogen; product discharged
