The State of Moisture Transport Rate Calculations in Wood Drying
AbstractThe drying theories developed over the past fifty years have originated from the point of view of either the internal mechanisms of drying, which treats the flow of moisture within a porous material, or from the view of the external mechanisms of drying, which considers the movement of moisture away from the material. This paper considers the success the drying scientist has had in analytically predicting the moisture transport rates, suggests means to realize overall drying rates, and recommends areas of specific research required to obtain a technology which will result in faster, more economical, and more uniform drying of lumber.
