Excerpt from The Kiln Drying of Lumber: A Practical and Theoretical Treatise But it is not with the living tree that our present subject has to do - all of that belongs to the province of Forestry - but rather with the product after the tree has been cut down and sawed into lumber or other forms of wood. Lumbering and Forestry are not an titheses, but both Should accomplish the same result, the perpetuation of the forest for future use, whatever that may be. Lumber is a crop, as are vegetables, and the forest may be utilized, and at the same time conserved for future use.

Excerpt from Kiln-Drying Hardwood Lumber The information secured upon cost indicates - especially among smaller operators, where economies are less carefully studied - the widest divergence. The extreme figures, for products not widely different, are 75 cents and $5 per thousand feet. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from High-Temperature Drying of Lumber: A Review Past research has shown that the mechanism of moisture movement during the constant rate and falling rate periods is not clearly understood; that flow velocity is more important in high - temperature than in conventional drying; and that equilibrium moisture content of wood at high temperatures is lower than at room temperature. Reported advantages of high-temperature drying include short drying times, reduced inventory, lower energy requirements, reduction in Shrinkage, and a lower equilibrium moisture content in use. Disadvantages reported are higher initial equipment cost, greater power requirements and heating capacity, discoloration of the wood, knot dropout, conditioning problems, Strength loss, and greater degrade with some Species.

At present, no single book adequately covers a basic understanding of wood book satisfies the need for such a work. It describes drying in practice. This the fundamental basis of kiln-drying technology, to enable forest companies to imFrove their drying operations as high-quality timbers become scarcer and of yesteryear can no longer be tolerated. Adaptive the wasteful practices is no longer good enough. Innovations change based on past experience of the material being dried and the processes require a sound understanding of drying. Newer techniques, such as the use of ultrahigh temperature sea soning and superheated steam under vacuum, require an even greater depth of physical understanding for these methods to be used effectively and economically. book provides a description of modern ideas about wood structure, This moisture movement and stress development, from which models of the drying process are developed to give the kiln operator important information about the course of drying under specified conditions, and thus a means is compared with practice wherever for rational process improvement. Theory possible.
