![]() By increasing the microwave output powers and decreasing the sample amounts, the effective moisture diffusivity values ranged from 3.982×10−11 to 2.073×10−10m2s−1 and from 9.253×10−11 to 3.162×10−11m2s−1, respectively. model gave a better fit for all drying conditions applied. Among of the models proposed, the semi-empirical Midilli et al. To determine the kinetic parameters, the drying data were fitted to various models based on the ratios of the differences between the initial and final moisture contents and equilibrium moisture content versus drying time. ![]() By increasing the microwave output powers (180–900W) and the sample amounts (25–100g), the drying time decreased from 12.50 to 3.0min and increased from 6.60 to 16min, respectively. The effect of microwave drying technique on moisture content, moisture ratio, drying rate, drying time and effective moisture diffusivity of mint leaves (Mentha spicata L.) were investigated.
