A study of the degree of hydration versus MR clearly indicated a loss of information for the latter parameter that could be crucial when optimizing a drying process. In addition, the MR is unsuitable for deriving fundamental parameters such as sample humidity and velocity of water release, or for determining energy parameters such as the Gibbs free energy change, enthalpy and entropy of water release. Another important advantage of using the degree of hydration instead of MR (and the subsequent data treatment) is the ability to predict new conditions by interpolating and extrapolating from the theoretical data. The use of contour plots provide additional information that allows comparison of the different temperatures and drying times that can be used to obtain a specific product. Such an analysis can be useful in selecting other parameters used in the drying process, e.g., the air velocity of the drier and sample thickness. A better analysis of the drying data based on the approach proposed here could improve the predictions and interpretations furnished by the models. In this regard, the benefits of modeling may be empirical and constrained to specific products and processes.
