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.
The vacuum inside the dryer allows vapour to be removed at low temperatures, which makes the conical screw vacuum dryer ideal for drying heat-sensitive products. The vapours are removed through a dust filter fitted on top of the vessel.
