Rotary Double Cone Vacuum Dryer (RCVD)/Rotocone Vacuum Dryer With Lump Breaker

Rotocone vacuum dryers (RCVD) are suitable for free flowing materials which are readily converted from slurry or wet cake to free flowing powder without exhibiting sticking or lump forming properties during the course of drying operations. All (RCVDs) have inclined indirectly heated surface. The Rotary Double Cone Vacuum Dryer action permits gentle folding and mixing of the material thereby enabling it to come in contact with the indirectly heated surfaces resulting in vaporization of the moisture in the wet particles. The vapour is sucked out by vacuum inside the dryer. Operating in a vacuum, reduces the boiling point of the solvents and consequently the evaporation is faster and takes place at a much lower temperature than would be applicable at atmospheric temperature. Vapour from the dryer passes under vacuum through a cyclone separator into a condenser and is eventually collected in a receiver. Recovery of the solvent is almost 100 percent.
