Abstract :The drying of rainbow trout in a square cross-sectional drier is examined to analyze the system in terms of the energy and exergy by considering thin-layer drying approach. In the experiments, the inlet velocity of air was kept to be constant at 1.5 m/s while varying the temperature of inlet air of 38, 46 and 53 C with relative moisture ranged from 28 to 43 percent. At the beginning, moisture content of specimen insert ignore into journalissuearticles values(fish); on wet basis was found to be around 75 %. The energy analysis on the consumed energy for the drying process was performed by considering the energy balance. Moreover, the exergy analysis was actualized by considering the second law of thermodynamics to identify the efficiency of device and magnitude of energy losses. At the beginning of the drying the energy consumption was high on account of the large moisture content and decreased with decreasing moisture content. The exergy for inflow and outflow was observed to be increased with increasing the air temperature used for drying process. Furthermore, it was observed that the lower temperature of the drying air, the lower exergy losses for entire drying period in range of 0-900 minutes.
