Drying energy balance
http://www.rpaulsingh.com/course/lectures/dehydration1.html WebThe fluidized bed drying system is divided into the following subsystems: the blower, the heater and the drying column. For fluidized bed drying, the most sig-nificant component is the drying column. Therefore, the thermal balance is derived by applying mass, energy and entropy balances to the drying column in batch fluidiza-tion shown in Fig. 1.
