Fitting cassava drying kinetic with a high order equation

The experimental drying curves with air flow rates of cassava parallelepipeds were analyzed at different and thickneses to obtain an empirical model for the cassava drying kinetics. Experimental results were modeled with first and higher order kinetic models. The kinetic parameters were fitted by non-linear regression to experimental drying curves with a power law model. The parameters of the power law model were statistically significant in a non-lineal joint interval confidence of 99%. The effect of temperature, air velocity and sample thickness on drying kinetic results, showed a consistent behavior with respect to drying theory.
