Mykychak B. Regularities of filtration drying of packed birch peeled veneer

The theoretical bases of hydrodynamics of the heat agent filtration through porous structure of the sheet materials, as well as generalization methods of these results are analyzed. The theoretical bases of external heat exchange between material dry surface and heat agent, as well as heat-and-mass transfer with material wet surface during the filtration drying are examined. The dependence between drying coefficients in the first and second periods was established. On the basis of kinetic results generalization the calculated dependencies are proposed. They allow to predict the drying time in the period of complete and partial saturation of heat agent by moisture and general time of drying as well.
