Available in PDF, EPUB and Kindle. Book excerpt: This paper gives the results of more recent research to derive satisfactory procedures for drying infected 4/4 red oak under conditions milder than kiln schedule T4-D2. This research followed principles of kiln schedule development in response to drying strain outlined by McMillen whereby three factors affecting drying stresses must be considered: Temperature, relative humidity, and time. Successful development of a schedule depends upon determining the optimum combination of the three factors during drying lumber from green to final moisture content (MC). Surface and end checking, honeycombing, and ring failure result from shrinkage stresses caused by drying wood below the fiber saturation point. Prolonged exposure to excessive temperature while any of the wood is above the fiber saturation point weakens the wood and increases its susceptibility to interior checking and collapse.

This book was released on 1972 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Northern red oak (Quercus rubra L.) lumber from trees with heartwood infected by certain anaerobic bacteria proved more susceptible to honeyconb and ring failure during kiln drying than similar lumber from non-infected heartwood. Before drying, infected heartwood that was sound and clear of stains appeared the same as non-infected heartwood. However, the infected wood could be distinguished from non-infected green wood by having abnormal sour vinegar and rancid odors which result from volatile fatty acid production by the anaerobic bacteria.

Available in PDF, EPUB and Kindle. Book excerpt: Reducing kiln-drying time for oak lumber can reduce energy requirements as well as reduce lumber inventories. In this work, 1-inch northern red oak and white oak were kiln-dried from green by a combination of individual accelerating techniques--presurfacing, presteaming, accelerated and smooth schedule, and high-temperature drying below 18 percent moisture content. Results were compared with those achieved by conventional kiln drying. Drying time in the combined techniques procedure was reduced by more than 50 percent. The results for quality of the lumber were mixed. In most of the material, the quality was acceptable, but enough honeycomb was present to be of concern. (Author)
