Özet
In this study, shad (Alosa fallax nilotica) was dried in microwave (360, 720 W), developed heat controlled microwave (50, 70 °C), hybrid microwave (350 W + 50 °C, 350 W + 70 °C) dryers. Drying time, drying rate-rate, effective diffusion, color, hardness, energy consumption (SMER, SEC), exergy energy, energy efficiency, heat-mass transfer value of the drying processes were investigated. The shortest drying process was determined as 450 seconds at 720 W power, while the longest was 414minutes at 50 °C. Effective diffusion values calculated for microwave, temperature controlled microwave and hybrid drying processes are 1.32–9.43 × 10−8 m2/s, 2.43 × 10−8-2.41 × 10−7 m2/s and 8.52 × 10−7-2.76 × 10−6 m2/s, respectively. Has changed between It has been determined that the most suitable drying method in terms of total energy consumption and energy efficiency values is the drying process performed in a temperature-controlled microwave dryer. Exin and Exout values of the temperature-controlled microwave drying process were calculated to vary between 2.20 and 5.16 J/s and 1.82–4.68 J/s, respectively. Exin and Exout values of the hybrid drying process were calculated to vary between 1.94 and 4.84 J/s and 1.70–4.68 J/s, respectively. The heat transfer values calculated for the temperature-controlled drying process varied between 0.104 and 0.00269 W/m2K and the heat transfer values calculated for the hybrid drying process ranged between 0.100 and 0.00270 W/m2K. It was determined that the most suitable drying processes for color characteristics were 360 W and 350 W + 50 °C. For the hardness value, it was determined that the 350 W + 70 °C drying process was statistically more appropriate (P < 0.05).
