The influence of the drying medium on high temperature convective drying of single wood chips



The influence of the drying medium on high temperature convective drying of single wood chips



Drying Technology 15(6/8): 1801-1813



High temperature convective drying of single wood chips with air and superheated steam respectively is studied theoretically. The two-dimensional model describes the coupled transport of water, vapour, air and heat. Transport mechanisms included are the convention of gas and liquid, intergas as well as bound water diffusion. In the initial part of the drying process, moisture is transported to the surface mainly due to capillary forces in the transversal direction where evaporation occurs.
