What is the reduced speed drying stage of a veneer dryer?

            The drying rate of the material in the veneer dryer equipment depends on the surface evaporation rate and the dispersion rate of the internal wet separation. Generally, the drying rate in the early drying stage is controlled by the surface vaporization rate. Then, as long as the external conditions of drying remain unchanged, the drying rate and surface temperature of the material remain stable, this stage is called constant speed drying stage;

            When the moisture content of the material drops to a certain extent, the internal moisture dispersion rate to the surface decreases, and is less than the surface vaporization rate, the drying rate is mainly determined by the internal dispersion rate, and continues to decline with the decrease of the moisture content, this stage is called the deceleration drying stage.
