A Vacuum Tray Dryer works under vacuum conditions on the conduction principle. Inside the dryer are several shelves having trays on which the products are placed. The top most shelf is a dummy shelf placed there to ensure proper heating and to prevent the dried powder from escaping into the solvent extraction system. The shelves are constructed hollow with baffles cum stiffeners placed in between shelves. Every shelf has an inlet and outlet nozzle and is connected to an inlet and outlet header through these nozzles.
A hot medium reaches the shelf through the inlet header and flows through the shelves in a uniformly zig-zag pattern ensuring faster heat transfer to the surface. This in tam heats up the trays on the shelves. The hot medium flows out from the shelf through the outlet header.
The inlet and outlet headers are designed in such a way that the now of the heating medium is equally distributed into each of the shelves. The dryer chamber is constructed from heavy-duty plates to prevent the plates from buckling during th vacuum operation. Additional limpet coils are provided in order to further stiffen the body and to pass on the hot medium. The chamber is provided with a heavy door and adequate locking arrangement. The dryer chamber is connected to a shell & tube by means of a vapour column to a Heat Exchanger. This in turn is connected to a condensate receiver.
Vacuum is applied to the condensate receiver. Vapour evolved during the drying process collects in the receiver after it is cooled in the heat exchanger. The vapour to be cooled is passed through the tube side of the Heat Exchanger, while cooling water is passed through the shell side. A cooling coil in the condensate receiver cools any vapours entering the receiver before it goes into the vacuum pump. The condensate receiver is connected to a vacuum trap to make sure that any uncooled vapours from the receiver get trapped thus minimising the vapour content entering the vacuum pump.
Vtd Vacuum Tray Dryer
Application VTD – 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 nozzleApplication VTD – Vacuum Tray Dryers are used to heat and dry material under vacuum drying and drying materials due to high toxic contents, nature, heat sensitive.
