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

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 trays. Drying experiments were conducted at...
