birch peeled veneer

External heat-and-mass transfer during filtration drying of packed birch peeled veneer has been investigated. The dependence of heat-and-mass transfer coefficients on actual speed of heat agent filtration has been determined for dry and wet veneer sheets. The effect of heat agent temperature on the values of diffusive, heat and hydrodynamic boundary layers, and as a result, on heat-and-mass transfer intensity has been established by the experiments during filtration drying of packed veneer.
