e0“The experiments were also carried out to dry 2 kg of sliced apples spread over the drying trays”
e2“The experimental results showed that single-pass and double-pass collectors have daily efficiencies of 42.77% and 56.10%, respectively, with average exergy efficiency values ranging from 31% to 49% for single-pass and 51% to 67% for double-pass”
