Ravi International Rotocone Vacuum Dryer diagram. We are leading Manufacturers of Rotocone Vacuum Dryers. RCVD batch type of Vacuum Dryers. They are however suitable for only 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. The RCVD is of the Rotary type, having inclined indirectly heated surface. The rotary 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 solvent. 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.
APPLICATION DATA :
a) RCVD are used for free flowing, temperature sensitive materials.
b) It is also used for Drying expensive Pharma materials where high degree of purity is required.
c) Nitrogen blanketing can be provided by way of seals at charging and discharging points, for drying of highly explosive materials.
