Abstract. Fluidized bed processing of multiparticulate is a common technology used in the pharmaceutical industry. It is used for drug layering onto an inert core material, seal coating of drug containing cores, and the final functional coating. The fluid bed technology has evolved in various configurations, based on a top spray, …

The process of spray drying in detail. Liquids containing solids, such as solutions, suspensions or melts, are sprayed into a fluid bed, spouted bed or into the pulsating gas stream of the Glatt powder synthesis. Due to the high heat exchange, the aqueous or organic solvents evaporate immediately. The solids directly form small particles.

Fluidised-Bed Agglomeration and Coating. In a batch fluidiser (Uni-Glatt, Weimar, Germany) solid particles (~500 g) were fluidised by hot air (70 °C) and moistened on the surface by spraying a binder solution to finally obtain, after drying, either larger agglomerates or coated individual particles (Fig. 14.1). The air bed temperature was ...

The shaping process for granulation takes place in a closed vessel equipped with mixing tools and a chopper. The particles are simultaneously pulverized and mixed while a binder liquid is added. This creates liquid and solid bridges and very dense granules are formed. Originally, the granulating liquid was poured into the product.

Wet granulation (also wet blending) in the high-shear mixer is a classic process for building up granules from powder. This process is used when rapid agglomeration to form relatively compact granules is desired and the solid, pre-applied starting materials have low adhesive properties of their own.
