The problem of contact drying of a layer of moist material 
placed on a hot isothermal surface is considered. A system of heat 
and mass transfer equations and equations for the initial and boundary 
conditions are proposed. Luikov's theoretical approach is utilized, 
but all relevant thermophysical coefficients are considered to be 
fully dependent on the temperature and moisture content inside the 
material during the process. The model is solved numerically. Results 
for temperature and moisture distributions inside the layer of the 
material obtained using this model are compared to results obtained 
by solving a model with constant thermophysical coefficients in the 
governing equations, formed by using the same type of heat and mass 
transfer equations and equations for the initial and boundary conditions. 
The process is also examined experimentally, which provided results 
that enable verification of the proposed models.
