RCVD / Double Cone Rotary Vacuum Dryer

Application & Process

The Prism Double Cone Rotary Vacuum Dryer It is suitable for the raw materials that need to concentrate, mix and dry at low temperature for example, biochemistry products in chemical, pharmaceutical and foodstuff industries. Particularly it is suitable for the raw materials that.

• Material that cannot undertake high temperature.
• Material that is easy to oxidize.
• Material that do not permit to destruct.
• To recover material with residual volatile.
• Material with vigorous irritative and toxicity

The Prism Double Cone Rotary Vacuum Dryer consists of a jacketed double conical shell rotating around 6 RPM with under the state of vacuum inside the shell, pass steam or hot water in to jacket for heating. The large heating surface area presented by the internals of the cone ensures uniform drying of the product, as the product gently tumbles while the cone rotates slowly. The vaporized air can be pumped out through vacuum exhaust pipe when the damp raw material absorbed heat. The diffusive action induced by the tumbling cone constantly presents a fresh layer to come into contact with the indirectly heated walls of the shell, the drying rate of raw material is quickened and uniform drying efficiency is raised too. A well-designed sealing system enable maintenance of deep vacuum inside the shell, and also ensures positive circulation of a heating media in the jacket
