PTS Batchmixer The mixing process is an important process in the handling of bulk materials, especially in the pharmaceutical sector, where highly active substances must be mixed as carefully as possible and free of contamination. Choosing the appropriate mixing technology is therefore of paramount importance. The Batchmixer, developed by Dec, is the only mixing system that has no mechanical or moving parts and achieves sophisticated mixing processes. The system is based on the PTS - Technology (Powder Transfer System) and uses vacuum and pressure. A homogeneous mixture by circulation is obtained in a short time. The powder to be mixed, even hygroscopic or explosive substances, is sucked in, circulated for a while in the container and after the mixing process completely emptied. Due to the dense phase conveying with reduced flow velocity the particles remain largely intact. The closed system provides a very high degree of containment. Academic studies have shown that the

PTS technology Based on the PTS-Technology the Batchmixer (patent pending) was developed by Dec to mix active substances in a self-contained system. This system allows contamination free and product friendly mixing (no rotating mechanical parts) in batch mode under inert conditions. This offers the possibility to mix hygroscopic, oxygen sensitive or explosive powders. Various powders can be mixed with large differences in mixing ratio (1/10.000) at a low mixing time. A high ratio of no-load to full-load can be realized (High turn down ratio < 10% - 100%). The Batchmixer is practically maintenance free and can be cleaned in place (CIP). This technology is able to be integrated easily into all kinds of production lines, because powders are transferred, mixed and discharged in an automatic and closed way.

The demand of toady’s factories for a modern mixer includes high capacity range, easy cleaning and small dimensions to safe space. Gericke’s GMS mixer is equipped with horizontally aligned double shaft rotors and is offering a very interesting ratio of mixer’s volume and required headroom. A 2000 l volume mixer needs less than 1.5 m headroom! The mixing tools create a fluidised bed which allows the particles to move easy and quick in the mixing chamber, without introduction of energy that would destroy the particles. Gericke therefore calls the mixer ‚Multiflux‘ mixer. The typical mixing time is below 1 minute and avoids the breakage of different ingredients like powders and agglomerates. The special shape of the mixing paddles allow the quick and efficient emptying of the mixer after a production cycle. The low number and good access to the mixing paddles makes the cleaning easy. Gericke supplies all additional equipment being necessary to fill the
