ABSTRACT
The two generic drying ic models accepted by the majority of drying researchers are the lumped parameter model typically represented by the van Meel characteristic drying function model and the distributed parameter model typically represented by the Luikov continuum models. The first model is a semi-empirical model which hypothesises that there exists a unique characteristic drying rate function for a solid material and that the form of this function indicates the modes of moisture transport in the material. The second model is a diffusion-like continuum model with mass content, temperature and pressure gradient driving the heat, mass and momentum transport. The major advantage of the first model is the easy parameter estimation by using standard least square regression algorithm, whereas the parameters of the second model are more difficult to isolate and estimate quantitatively especially for the case of moisture content and temperature dependent parameters such as moisture diffusivity.
