The kiln drying of lumber; a practical and theoretical treatise . hygroscopicmaterial which is to be dried. Evidently, many ofthese have failed to produce the results anticipated orhave been impractical from a commercial standpoint,since there are to-day only about twenty-five kinds incommercial use. Other Kinds of Driers.—While this publication willconcern itself primarily with the subject of lumberdriers, mention should be made of apparatus for dry-ing other materials. Where the wood is sufficientlythin, namely, quarter inch or less, it is usually driedin a totally different kind of apparatus, called a veneerdrier. A typical form of this apparatus is shown inFigure 9. It consists of a long flue or box, about 50 to100 feet long by 8 feet high and 6 to 13 feet this flue is carried horizontally on rollers aseries of steel belts composed of short, narrow, flatlinks hinged together lattice fashion so as to allow ofslight lateral motion, and to present a perfectly flatsurface. The thin wood or veneer is fed into the |K^-¥^ys J|^a^ M^iSSH.
