Abstract

In this study, white cherry fruit was dried using different solar drying processes (P, F1, F2, F3, and Open). Drying experiments were continued until the samples reached an average moisture content of 0.10 ± 0.019 g moisture/g dry matter. The effects of drying techniques on drying behavior, drying rate, effective moisture diffusivity, energy consumption parameters (SMER and SEC), and exergy-based performance indicators were systematically examined. The drying rates were observed to range between 0.00097 to 0.0032 g moisture/g dry matter. The effective moisture diffusion values varied between 3.91x10-8-6.89x10-7 m2/s. The F1 drying process was found to be the most suitable in terms of total energy consumption. The SMER values ranged from 0.00036 to 0.0034 kg/kWh. The Exergy input, output, Exevap, Ex-Vdryer, and Ex-Vdrying values for the drying processes were found to range from 1.29 to 2.45 J/s, 0.266 to 0.420 J/s, 1.15-2.98x10-3 kJ/kg, 0.089 to 0.149, and 0.112 to 0.253, respectively. Furthermore, sustainability and improvement index values were found to vary between 1.098–1.180 and 0.90–1.91.
