Abstract

A mixer-granulator, preferably a spiral path granulator, is combined with a pneumatic conveyor dryer in a process for converting a solution or suspension into a dried particulate product. In a preferred embodiment, the particles formed in the mixer-granulator show a non-equilibrium moisture distribution with an interior part of lower moisture content and a surface part of higher moisture content.
