Voice Engineers is supllier and Rotary Vacuum Dryer Manufacturer. In rotary vacuum dryer which are jacketed cylindrical vessel, wet feed is charged as a batch and is subjected to indirect heating while undergoing agitation due to the action of paddle mixing. These dryers have specially designed scraper blades which scrap the entire internal surface of the dryer and continuously move and rotate the material, thereby precluding the possibility of material remaining in contact with hot surfaces for protracted periods of time. The operation is normally carried out in vacuum. Recovery of solvent is possible by condensing the vapours generated during the drying operation.
Special Features of Rotary Vacuum Dryer
Rotary Vacuum Dryer Manufacturer has some typical applications in pharmaceuticals, organic chemicals, pasty materials, insecticides, pesticides, solvent recovery, dye intermediates, dyestuffs, etc.
Rotary Vacuum Dryer Manufacturer also known as Vanuleuth Dryer, is a cylindrical jacketed vessel with a central agitator having specially designed blades. The blades of this Rotary Vacuum Dryer Manufacturer are so designed that they sweep the entire internal surface and at the same time turn the material so that all the particles are come in contact with the heated surface.
The central agitator shaft is supported on the two end bearings housed in bearing housing in such a way that the alignment remains always intact. This central agitator is driven by means of a Motor & Gear box through the bull Gear.
Cooling could also be provided by cold water / brine refrigerant through the jacket. The horizontal shell is jacketed to heat the shell with steam / hot water or any other thermal fluid. Limpet coil is provided instead of jacket if the heating media is fluid.
A Dust Catcher consisting of bag filter is provided on the top to prevent Rotary Vacuum Dryer Manufacturer the losses of material particles after the drying process. A Condenser of adequate heating surface area is provided wherein the evaporated vapors are condensed and these condensed vapors are then collected in the receiver of suitable capacity, placed beneath the condenser.
