Vacuum Tray Dryer (VTD)
ApplicationVTD - Vacuum Tray Dryers are used to heat and dry material under vacuum drying and drying materials due to high toxic contents, nature, heat sensitive. Vacuum Tray dryers use for API pharmaceutical, Herbal, chemical & foodstuff.Vacuum Tray Dryer is a static type of dryer used in various industries under vacuum atmosphere to dry temperature sensitive materials as well as pharmaceutical and allied products. It gives complete drying and vaporization of moisture of the product. We at Bhagwati Pharma are manufacturer of Vacuum Tray Dryer. The vacuum tray dryers are been customized according to the clients specification and the available capacities ranges from 6 to 96 trays per batch.They are suitable for various purposes that includes pharmaceutical, Herbal, chemical & foodstuff.Vacuum Tray Dryer works on the principle of conduction considering the vacuum conditions. There are several shelves placed under which products are placed. Top shelves gives proper heating and helps to prevent dried powder from escaping into the solvent extraction system. Baffles are been placed between the shelves. It contains an inlet and outlet nozzle both are connected to its own header throughout its own nozzleAdvantages of the Vacuum tray dryers:Efficient heat sensitiveDrying of Materials in ContainersLower Drying Temperature than Standard DryersFaster Drying due to Large Surface AreaComparatively Dries Large Moisture than Normal DryersGives High Quality Dried MaterialStainless steel construction (SS 316L/316/304)Removable Hollow Pad Type Heating ShelvesDedicated Circulating Systems & Fluid HeatingThermal efficiency Range - 60% to 80%Provision for Explosion Vent / Rupture Disc on body & Validation Port on BodyChamber provided with Vacuum break ValveQualitative Interlocking for Doors to ChamberUniform Heating FlowBranded Immersion HeatersHeavy duty MS / SS Door Fitted on HingesFor Large Models – Single & Double DoorsComplete Automation w/ PLC controls (Optional)Models: 6, 12, 24, 36, 48, 96 & 192 Trays.
Salient features :

- The medium flowing through the heating plates is water, steam, or thermal oil.
- The distance between the heating plates is determined primarily by the surface loading and the foaming of the product.
- Channel type heating shelves for faster heat transfer rates.
