Drying characteristics of amaranth grain

Thin-layer drying of amaranth grain was conducted at 40, 50, 60 and 70 °C and a moisture range from about 32.5% to 5.0%, dry basis. A mathematical model based on Fick' s second law of diffusion with variable diffusion coefficient for spherically shaped grain was used to predict the drying behav...
