Modeling and experimental validation of an indirect active hybrid solar dryer for mint leaves: Coupled thermal and moisture-transfer analysis

A mathematical model was developed and experimentally validated to predict the thermal performance and drying behavior of an indirect active solar dryer (IAHSD) for mint leaves. The distinctive contribution of the proposed approach is its integration of solar-energy input, auxili...

Environmental sustainability and thermodynamic evaluation of a solar dryer with zigzag airflow during henna leaf drying

Abstract This study developed and evaluated a solar dryer with a zigzag airflow pathway for drying henna leaves under Egyptian climatic conditions. The system was designed to improve air‐product contact in tray drying by directing heated air alternately above and below the drying...
