摘要：

Recognised for its excellent mixing capabilities and its optimal heat and mass exchange, fluid bed technology is being increasingly applied in the food industry where drying, coating, agglomeration and/or mixing processes are involved. The primary factor influencing fluidised bed processing, is the air flow and its distribution. Numerical modelling techniques such as Computational Fluid Dynamics (CFD) provide an important means to investigate air flow distribution through specific equipment. In this paper,, CFD simulation results of the air flow in a Glatt GPCG-1 lab-scale fluid bed in which stainless steel woven wire mesh distributors were used, are presented, together with the results of verification experiments. As an unequal air flow inside the plenum was found to occur, CFD was used as a design tool to investigate reactor configuration changes in order to obtain a more homogeneous air flow towards the distributor.
