Fluidized bed drying is a frequent method for drying of moist particles. This method improves heat and mass transfer coefficients considerably. In this article, exergy analysis of fluidized bed dryer in bubble regime was established and developed. The exergy efficiency has been introduced as main criteria for optimizing the operation conditions and also the effects of different parameters as drying time, particle moisture content, air mass flow rate and air velocity on exergy efficiency, were been investigated.
