(Received November 15, 2006) CORE

Fluidized bed drying is a process of contact between the two phases. The solid phase, under fluidization con-ditions, assumes a "fluid like" state. When drying air is passed upward through a layer of wet material, as shown in Fig. 2, the gas will pass at low flow rates through the fixed bed of particles. As the gas velocity is increased, the pressure drop across the particle layer will
