Özet
Food drying involves intense energy consumption; therefore, using solar energy instead of conventional ovens is an important alternative owing to sustainability and environmental impact. In this study, the effects of energy sources (grid electricity-GE, PV system, and grid + PV), light sources (Daylight-DL, LED, and DL + LED), and light intensities (2500, 7500, and 10,000 Lux) on energy/exergy efficiency, specific water removal ratio, improvement potential and impact categories were investigated for the developed Photovoltaic-Assisted Daylight Simulated Dryer (PVDD) system. In addition, the relation between the efficiencies and environmental effects was evaluated by correlation analysis. In the GE scenario, eta(energy) and eta(exergy) values ranged from 10.7 to 24.4 % and 1.55-4.48 %. In the GE + PV scenario these values ranged from 17.2 to 68.6 % and 3.67-33.3 %. Significant effects of energy source, light intensity and light source were determined (p < 0.05). In the case of LCA analysis, agricultural production had more than 60 % impact on the environmental impact values in the case of PV. The use of GE had relatively higher environmental impacts than PV. Efficiency values showed a negative correlation with all impact categories except land occupation. The results indicated that the system parameters significantly affected the environmental impacts and should be considered for the development of food processing.
