Moisture sorption isotherms and drying kinetics of Moroccan rosemary

Sorption isotherms and drying kinetic of Rosmarinus Officinalis are experimentally investigated. Water sorption isotherms of rosemary leaves are studied at three temperatures: 30, 40 and 50 °C, using the standard static gravimetric method. The drying kinetics was studied for four different air temperatures (50, 60, 70 and 80 ° C) and two air flows drying (300 m 3/ h and 150 m 3/ h) for an ambient temperature in the range of 26-37 °C.
