A model to simulate the drying process of alfalfa is presented aiming to produce design data for alfalfa dryers. The drying profile of a fixed bed dryer has been simulated through a system of five partial and ordinary differential equations, which describe the changes of the physical properties of the product, as well as the thermodynamic data of the drying air. The equations were solved using the thin-layer drying theory. In order to check the accuracy of the model, the drying rate curves were
