DEC (Dietrich Engineering Consultants sa) developed the PTS-Batchmixer to mix active substances without modifying their physical properties and without the risk of contamination for operators. It transfers, mixes and discharges products fully automatically and is especially suited to the needs of the pharma industry.

The PTS-Batchmixer mixes powders with large differences in ratio (1/10,000) and totally different properties in a totally contained way. The system comprises a main container with an integrated central deflector. A PTS powder transfer system with two tangential inlets is installed on top of the container. Powders are introduced automatically and circulated in the container. The deflector guarantees a homogenous distribution of the mixture in the container.

The mixing effect in the PTS body when the two jets of powder meet, increases the speed and effectiveness of the mixing process. As the speed at which the powders are circulated is limited, particles are not damaged. The system can operate under inert conditions, thus hygroscopic, oxygen sensitive or explosive powders can be mixed.

This technology is easy to integrate into production lines. Powders can be transferred automatically from drums, sacks or even process equipment (e.g. a dryer, etc.). After mixing, the system can be automatically discharged into the next production step. It has no moving or rotating mechanical parts, requires little maintenance and is easy to clean automatically.
