Vacuum Tray Dryer (VTD)

Able Engineers Private Limited manufactures Vacuum Tray Dryers (VTD) designed for drying heat-sensitive materials that may decompose, oxidise, polymerise, or deteriorate at higher temperatures. These dryers are widely used in Herbal Extraction Plants, Pharmaceutical Plants, Chemical, Nutraceutical, and Food Processing industries for efficient moisture removal under controlled vacuum conditions.

A Vacuum Tray Dryer operates at reduced pressure, which lowers the boiling point of moisture and solvents present in the material. Consequently, it allows drying at relatively low temperatures and helps protect products that cannot withstand conventional high-temperature drying.

Able Engineers Private Limited manufactures industrial Vacuum Tray Dryers with a focus on drying efficiency, reliable operation, and product quality. The equipment can also support sterilisation before the drying process, depending on the system configuration. Its closed-chamber design helps prevent unwanted external matter from entering the product during normal operation.

Inside the Vacuum Tray Dryer, operators place the material on trays and load them into the drying chamber. They then close and seal the chamber door before starting the vacuum pump. The pump reduces the pressure inside the chamber. Meanwhile, steam passes through the space between the trays and the heating jacket or shelves. Heat transfers to the material through conduction, allowing moisture to evaporate under vacuum conditions.

Working Principle of Vacuum Tray Dryer (VTD)

The Vacuum Tray Dryer works on the combined principles of vacuum drying and conductive heat transfer.

First, operators spread the material evenly across the trays and place them inside the drying chamber. Next, they seal the chamber and start the vacuum pump to reduce internal pressure.

At the same time, steam circulates through the heating jacket and shelves. These heated surfaces transfer heat to the material through conduction. As the vacuum lowers the boiling point of moisture, the material releases moisture at relatively low temperatures.

Furthermore, the vacuum system removes the generated vapours from the chamber. This process helps achieve efficient drying while reducing the risk of thermal degradation in sensitive materials.

Features of Vacuum Tray Dryer (VTD)

• Low-Temperature Drying: Suitable for heat-sensitive materials that may deteriorate at higher temperatures.
• Vacuum System: Uses a vacuum pump to maintain reduced pressure inside the drying chamber.
• Conductive Heat Transfer: Transfers heat through steam-heated jackets and shelves.
• Closed-Chamber Design: Helps prevent unwanted external matter from entering the product.
• Sterilisation Compatibility: Can support pre-drying sterilisation, depending on equipment configuration.
• Efficient Moisture Removal: Helps evaporate moisture at lower temperatures under vacuum conditions.
• Multiple Tray Arrangement: Provides a large surface area for drying different materials.
• Controlled Operation: Allows operators to manage drying conditions according to product requirements.
• Customised Construction: Equipment capacity, heating arrangement, and material of construction can be selected according to the application.

Applications of Vacuum Tray Dryer (VTD)

Vacuum Tray Dryers are widely used in industries where materials require controlled drying at relatively low temperatures.

• Herbal Extraction Industry: Drying herbal extracts and plant-based materials obtained during extraction processes.
• Pharmaceutical Industry: Drying heat-sensitive pharmaceutical ingredients and intermediate products.
• Chemical Industry: Drying suitable chemical compounds, powders, and materials containing volatile solvents.
• Nutraceutical Industry: Drying nutritional ingredients and sensitive plant-based extracts.
• Food Processing Industry: Drying suitable food ingredients that require controlled temperature conditions.
• Laboratory Applications: Drying samples and materials under controlled vacuum conditions.
