Airflow in Batch Fluid-Bed Processing

Dilip M. Parikh, Niro Inc Significant amounts of solid materials are processed using fluid-bed technology. Suspension and movement of particles in an airstream maximizes the exposure of particle surfaces to air or gas, producing efficient evaporation. The primary factor influencing a fluidized-bed process is airflow. To understand and manipulate processing in a fluid bed, it is important to learn how airflow is generated, conditioned, and distributed through the bed during drying, agglomerating, and coating. This article describes how uncommon pressure drops and related processing problems can be identified and rectified by studying the airflow of the system
