چکیده مقاله:
Drying process has various applications in industry. This process which is a thermal energy operation has various applications in drying food, wood, edible grains and various chemical and cellulosic materials. Consuming high amount of energy during in drying industry has turned this process to one of the high-energy-consuming operations, while it has a high industrial significance. In recent decades, thermodynamic analysis, especially exergy analysis, has turned to one of required tools in designing, analyzing and optimizing thermal systems. The following research tries to present drying process thermodynamic modeling, and especially fluid bed drying and simultaneous equations in mass and heat transfer. Also, it is tried to derive exergy returns in the form of a heat and mass transfer parameters function and its changes are studied based on inlet air heat, air specific exergy, exergy difference between input materials and output products, product weight, air humidity contents, and inlet/outlet air humidity ratio. This model could be advantageous in optimizing drying operation and determining proper application of each system, and optimized system shape and order.
