Abstract
In this study, an experimental investigation was carried out on solar system consists of many main components; solar air collector, drying chamber and air blower. Manufacturing and an analysis of two active double-pass solar air collector integrated with unfinned and helical finned absorbers have been carried out. The helical fins increased the standers solar collector (unfinned) efficiency by about 6%. In five hours for 2 kg of apple slices drying, the final weight of the dried product is 1.237 kg using an unfinned solar collector, while 1.039 kg using helical finned solar collector. Keywords: solar drying, air heater, thermal performance, helical fins.
