| Abstract | ||||
| This work focuses on studying the influence of drying temperatures and system on the quality of pomegranate and energy requirements. The effect of peels thickness was also studied. Drying costs were determined. Drying temperatures that used were 50, 60 and 70 °C for hybrid solar and artificial drying systems. The peels layer thicknesses were 1. 2 and 3 cm. weight loss, moisture loss, drying rate, energy consumption and costs were determined. The results revealed that the drying pomegranate in artificially (oven) recorded the highest weight losses (77.72%) at 70 °C compared to the other system and temperatures. The moisture content of pomegranate peels ranged from 215.10 to 258.68 and 218.88 to 263.75 % d.b. for both solar and artificially drying systems, respectively. The drying rate of pomegranate peels ranged from 60.89 to 135.75 and 61.44 to 136.50 gwater kg-1 h-1 for both hybrid solar and oven drying systems, respectively. Using the oven drying system recorded the highest energy consumption at the lower type, where, it recorded 2.12 kW kg-1 dried, which inturn recorded the highest cost of 1 kg dried product, where it recorded 13.62 LE kg-1 at the same conditions. | ||||
