Powders are explosive
Spray drying is a part of powder processing and poses a special risk.
During the process dust is produced in a chamber with high temperatures, resulting in a risk of explosion under ideal circumstances. Often, these ideal circumstances are unpredictable, and sometimes very little is necessary for an explosion to occur – the right concentration of dust, turbulences, a source of ignition, or spontaneous combustion.
This is calling for producers to use equipment that is considering all preventive measures that can be taken to avoid explosions.
