Analyzed is the problem of unsteady heat and mass transfer inside the moist colloidal capillary-porous body during the process of combined conductive-convective drying. Observed is the case when the layer of moist material is placed 
on the heated surface of constant temperature, while over the opposite free surface of the material, air of certain temperature, relative humidity and velocity is blown. Heat is supplied to the material primarily conductively, 
and removed convectively. The water vapor, evaporated inside the material, as well as on its free surface, is removed convectively.
The mathematical model of the process is formed following the principles of thermodynamics of irreversible processes. The equations describing combined heat and mass transfer in the layer of moist material, 
as well as the corresponding equations for the initial conditions and the boundary conditions at contact and free surface, are formed considering all thermophysical properties of the material to be fully dependent on local
temperature and moisture content inside the body during the process.
