Apparatus Design Features with an Influence on Product Quality 

The design of central as well as peripheral elements of spray fluidized bed equipment has been discussed in considerable detail by Jacob (2007), so that it is sufficient to give here a brief summary before focusing on some special aspects of apparatus design with high relevance for product quality. 

Important elements of the periphery of spray fluidized beds are  

The main central elements of spray fiuidized bed equipment, which have also been 

Each of the mentioned main constmctive elements of spray fluidized bed equipment can be used to manipulate product properties in the desired direction. For example, droplet size and spray pattern have an influence on the particle wetting and on the local liquid distribution in the fluidized bed - thus also on particle growth kinetics, the type of particle size enlargement (agglomeration in comparison to granulation and coating) and product properties (e.g., particle porosity and density, and surface morphology).
