Process principles
Agglomeration in the fluid bed (->
Fluid Bed Granulation) is a modern process for building up
powder granulates. In this process, powder is moistened in order
to form
liquid bridges between the particles. The spray liquid can either
be water or an organic solvent, a powder dissolved in water or
another
binder. The moistened granulates are dried and cooled as required.
Due to the relatively low mechanical forces in the fluid bed, the
agglomerates/granulates are loose, have a low bulk density and are
outstandingly soluble in water.
