Free of dead space

A state is considered dead-space-free when an apparatus has no stagnant areas. The entire volume is covered by flow, mixing, temperature control, or cleaning. No material remains in shadowed zones.

Dead-space-free designs are especially important in mixers, reactors, and dryers. They prevent product deposits, inhomogeneities, and contamination. They also facilitate complete discharge and hygienic cleaning.

Dead-space freedom is achieved through flow-optimized geometries, suitable internals, and optimized fittings. In bulk solids technology, complete flow coverage and homogeneous shear flow are key criteria for dead-space-free processes.

amixon® mixing systems are designed so that the entire mixing chamber is captured by the flow field. This results in reproducible product properties and high process reliability.
