Description: The drying process has been studied experimentally and theoretically but there are many difficulties in practical drying applications such as in agriculture. The solution to an engineering problem of a physical nature usually is formulated to be a mathematical expression of the specific model. A number of numerical methods are available with existing software for implementation to solve models but Taylor?s series was used for this study. Thin-layer drying rates of cowpea gotten from the International Institute of Tropical Agriculture were determined experimentally as a function of drying air temperature. Cowpea samples were exposed to convective air at drying temperatures of 55, 65, 75 and 85 ?C. Results indicated that cowpea drying is a diffusion controlled process and the characteristic drying constant also increased linearly with the product?s temperature. The experimental data obtained fitted into the Newton model have suitably illustrated the drying behaviour of cowpea with highest R2 of 0.9998 and lowest RMSE of 0.0109.
