In the field of pharmaceutics, spray drying is often used for producing particles with predetermined qualities. Produced particles are usually insulating in nature, and this property combined with small particle size, might lead to electrostatic problems. These problems involve, for example, dust explosions, fires, reduced process efficiency and particle accumulation on the walls. In the spray drying...
In the pharmaceutical industry fluidization is often used in drying, coating and granulation processes. During fluidization powder particles contact other particles as well as the walls of the vessel and this leads to generation of electric charges. These charges may result in sparks, dust explosions, fires, reduced process efficiency and particle accumulation on the walls. However, the mechanism...
