Abstract
A Wurster processor and a powder feed system are coupled via an eductor so as to supply dry powder through the air diverter sleeve of the Wurster for discharging onto the circulating particles during operation of the Wurster. Agglomeration and aggregation of the particles is eliminated or minimized by isolating or separating the liquid spray by the spray gun from the dry powder.
