Theory of Drying and Its Application to the New Humidity-Regulated and Recirculating Dry Kilns

Forest Products, Section of Timber Physics, Harry D Tiemann in Charge

Description

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. A correct understanding of the principles of drying is rare, and opinions in regard to the subject are very diverse. The same lack of knowledge exists in regard to dry kilns. The physical properties of the wood which complicate the drying operation and render it distinct from that of merely evaporating free water from some sub stance like a piece of cloth must be studied experimentally. It can not well be worked out theoretically. The thermal process of the drying operation, however, is capable of exact theoretical analysis. It is the purpose of this article to interpret the conditions which exist in the various stages of the dry ing Operation with respect to the heat quantities and the changes which occur in the drying medium, from a theoretical standpoint. The object of this analysis 1s to show the limiting conditions which may be approached, but can not be exceeded.
