Abstract

The current study investigated the environment indicators of a novel intermittent solar drying system (ISD) for drying agri-food products, and the drying behavior of onion slices during study. Mathematical modeling and environmental analysis of the ISD were compared with the stationary solar drying process (SDP). Thirteen well-known mathematical models were fitted to the drying data of the ISD and SDP. The obtained results revealed the lowest drying time using SDP at 13 h compared to ISD at 18 h. Where tempering in drying time decreased the diffusional process, consequently increasing the drying time. Among the examined mathematical models, Wang and Singh’s well expressed the drying behavior of onion slices during the ISD and SDP, with the highest correlation coefficient R2 = 0.99933 and 0.99691, respectively. The environmental indicators; the energy payback time (EPBT) was estimated = 1.81 using the ISD compared to 3.62 when using the SDP and the yearly CO2emission values = 0.205 and 0.123 tons using SDP and ISD, respectively. Both drying systems were found with high NetCO2mitigation = 49.3 and 19.6 tons per year using the SDP and ISD, respectively. The earned credit carbon (ECC) ranges from 980–3920 and 247–987 USD using the ISD and SDP, respectively. The ISD was found more suitable for drying agri-food products in terms of environmental indicators and ECC.
