The Batchmixer provides the ultimate in speed and flexibility, reducing overall process time compared to traditional systems, enabling the operator to mix powders with different characteristics in a contained environment. With applications from 2 litres to 5000 litres, the system also allows the operator to vary product volumes from 10-100%. The system is particularly appropriate for pharmaceutical applications where active substances must be handled without contamination or changes to physical properties.

This easily integrated system has a main container with an integrated central deflector and a PTS with two tangential inlets on top. The powders are automatically introduced by the PTS and circulated within the container for a predefined period of time. The deflector ensures homogenous distribution of the mixture. The mixing process is faster and more effective as a result of the two jets of powder meeting in the PTS body, but with limited circulation speed, particles are not damaged. The system operates under inert conditions for hygroscopic, oxygen sensitive or explosive powders.
