The Rotocone Vacuum dryer with improved technology integrates during operation under vacuum.

The rotocone Vacuum dryer facilitates enhanced drying efficiency, low temperature operation and economy of process by total solvent recovery. It helps GMP based working by achieving optimum dust control, while offering the advantages of efficient charging and discharging of materials. The Rotocone Vacuum dryer consist of a jacketed double conical shell rotating around 8 to 13 rpm with provision for application of vacuum inside the shell & circulation of heating media in the jacket during the rotation of the cone. The large heating surface area presented by the internals of the cone ensures uniform drying of the product, as the product quietly dropping while the cone rotates slowly. The diffusive action induced by the dropping cone constantly presents a fresh layer to come into contact with the indirectly heated wall of the shell.

The mechanical & rotary sealing systems used to enable maintaining of deep vacuum inside the shell, and also ensures positive circulation of a heating media in the jacket.

A suitably sized Condenser & receiver allow the solvent vapour to be totally condensed before being handled by the vacuum pump. In addition, provision for purging the inner shell of the cone with the suitable inert gas.
