displacement body

A baffle is a fixed or movable component within a piece of equipment that displaces usable volume. It reduces the free process volume and alters flow, mixing action or heat transfer. Baffles are installed in connections or inspection ports to prevent dead spaces. In these areas, they help to prevent product residues and cross-contamination.

Displacement bodies can improve the performance of a powder mixer. One example of this is the KoneSlid® mixer from amixon®. In this mixer, the displacement body enables low-energy mixing of different powders. At the same time, it facilitates rapid and virtually complete emptying of the unit.

The displacement body also adjusts the effective working volume. During this process, the product remains in contact with the mixing tools and the heat-transferring surfaces. Another special feature is static internal components that act as flow disruptors. These support the mixing and heat transfer processes. Dead spaces are reduced and process control is improved. This enables homogeneous processing to be achieved in mixers and vacuum dryers, even with partial filling.

Baffles influence flow patterns, residence times and heat transfer. They are frequently used in conical mixers, reactors and contact dryers. Their geometry is adapted to the product and the process.
