Calculation of the parameters of studied systems heat treatment (the process duration, temperature distribution inside the product and in its mass change) is complicated both by external and internal moisture transfer. In this regard, a strict mathematical description of moisture and heat transfer between the surface of the semi-finished product, which must be considered as a capillary-porous body, and the surrounding medium should be based on a joint solution of hydrodynamics equations and convective heat- and mass transfer, taking into account the normal component of the mass flow on the body surface, which complicates the task. Consideration of such a task with regard to moisture transfer under the action of water content gradients, temperature and pressure is possible if the driving forces of transfer processes do not consider these potential gradients on the surface of a capillary-porous body, but the differences between potentials averaged over the surface and volume of the body...
