Manufacturers of Industrial Equipments designed Rotary Cone Vacuum Dryer to operate in a vacuum. The vacuum of the Rotary Drum Dryer which removes vapours from the material when it is at low temperature and thus, an ideal unit for heat sensitive products. The dust filter is present at the top of the dryer used for removing vapors.
Wet feed is charged as a batch and is subjected to indirect heating while undergoing agitation due to the action of paddle mixing, The operation is normally carried out in vacuum. Recovery of solvent is possible by condensing the vapours generated during the drying operation.
