MODELING OF CONDUCTIVE DRYING POLYGRAPHIC MATERIALS OF CAPILLARY-POROUS COLLOIDAL STRUCTURE

An approach to studying the processes of thermal treatment (heating, drying) of some types of polygraphic materials is proposed, which is based on the theory of nonstationary heat and mass transfer. The approach has been approbated for the process of conductive (contact) drying of a board sheet. The results of numerical investigations are applicable in practice in studying the processes of heat and moisture transfer in capillary-porous colloidal structures, as a result of which optimization of the technological regimes of drying-out and provision of the required qualitative characteristics of the products is possible for both polygraphic and other industrial areas
