The succeeding modifications of the Lewis (Newton) model and
the Page model consist in introducing the additional terms and constants
into the models. The criterion of the modifications was the
goodness of fit of the formulated models to the experimental data.
The formulated after this manner equations are empirical models
which neglect the fundamentals of the drying process and their
parameters have no physical meaning. The formulated by authors
of this study models 11, 13, and 17 can be regarded as the modifications
of the Page model. Comparing with the models 2–9, similar
modifications of the Page model were lacking.
