Sanitary Mixing In Multi-Agitator Systems

Mixing is an integral part of food, beverage, dairy and pharmaceutical production. Within these industries, one of the most common specialty mixing systems in operation are multi-shaft mixers. These devices consist of a number of agitators working in tandem; for example, a low-speed anchor agitator producing bulk flow while a saw-tooth disperser blade turns at high speed to wet-out and disperse powders. Multi-shaft mixers are extremely versatile in terms of viscosity range (some models can handle up to ~1 million cP), shear levels and operating conditions (i.e. vacuum, heating/cooling, gas purging, etc.).

This bulletin discusses a few equipment features commonly supplied on multi-shaft mixers intended for sanitary applications.
