Dynamic drying system for high-purity and sterile processes

For many applications, it is useful to combine drying with motion. Powders and granulates are mixed during the drying process, thus ensuring uniform heat transfer to the product. In addition, the rotary dryer can be loaded and unloaded contamination-free and with reduced effort. The drum has a dual-cone design.

The efficient system was designed for efficient rotary vacuum drying. Its main advantage over conventional rotary ovens is that the drum of the RTSD has a single rotary joint. This means that the supply of heating medium, measurements, vacuum generation and the drive are all effected via the single rotary penetration. This enables an optimum installation in clean rooms for sterile processes.
