Recent Research and Development in Wood Drying Technologies in China

Abstract

This article reviews research and application in applied wood drying technologies in China during the last two decades. It covers four areas including texts, manuals, and standards; predrying treatments; drying techniques and equipment; and energy conservation. The predrying treatments section includes presoaking, presteaming and preheating, end coating, and warp control. Drying techniques and equipment discussed involve predrying and redrying, conventional drying, high-temperature drying, vacuum drying, dehumidification drying, and press drying. The energy conservation section describes electricity conservation and heat conservation. Finally, some suggestions and remarks are given on the past experience and perspective for future research and development.
