Northern red oak boards, 1 inch thick by 4 inches wide by 24 inches long, were dried from an initial moisture content of approximately 80 percent of various final moisture contents by radiofrequency electrical energy. Drying occurred rapidly above the fiber saturation point, but slowed down considerably below this moisture content. With the drying system used in this investigation, the average moisture content could be reduced in 15 minutes from 80 to 25 percent. However, the level of degrade in boards dried to 25 percent or below was probably too high for many oak products in which honeycomb is an important defect. The results did suggest that radiofrequency drying has some potential as a predrying process to be followed by lower temperature drying. (Author).

This handbook provides an overview on wood science and technology of unparalleled comprehensiveness and international validity. It describes the fundamental wood biology, chemistry and physics, as well as structure-property relations of wood and wood-based materials. The different aspects and steps of wood processing are presented in detail from both a fundamental technological perspective and their realisation in industrial contexts. The discussed industrial processes extend beyond sawmilling and the manufacturing of adhesively bonded wood products to the processing of the various wood-based materials, including pulp and paper, natural fibre materials and aspects of bio-refinery. Core concepts of wood applications, quality and life cycle assessment of this important natural resource are presented. The book concludes with a useful compilation of fundamental material parameters and data as well as a glossary of terms in accordance with the most important industry standards. Written and edited by a truly international team of experts from academia, research institutes and industry, thoroughly reviewed by external colleagues, this handbook is well-attuned to educational demands, as well as providing a summary of state-of-the-art research trends and industrial requirements. It is an invaluable resource for all professionals in research and development, and engineers in practise in the field of wood science and technology.
