In this work, firstly the sorption isotherms of henna leaves were determined using a dynamic vapor sorption (DVS) device at 3 temperatures (30, 40, 50 °C). The equilibrium data were well fitted by the GAB model. Secondly, drying kinetics were measured using a pilot convective dryer for 3 air temperatures (same as above), 3 velocities (0.5, 1, 1.42 m/s) and 4 relative humidities (20, 30, 35, 40%)....
This electronic document is a “live” template and already defines the components of your paper Simulation and optimization of the drying process may require the calculation of the water diffusivity of the product. In this work we have described the estimation of the coefficients of diffusion of the moisture in the henna leaves from the drying curves obtained with DVS device. Two different methods...
