Research Status and Application Prospect of Wood Hot-press Drying

The theoretical and experimental research of wood hot-press drying was summarized in this paper. The effects of hot-press drying technology on drying time, drying quality and physical-mechanical properties of wood were analyzed. The research on the heat and mass transfer regularity as well as establishment and solution of mathematical models describing heat and mass transfer were concluded so as to forecast hot-press drying process and control the drying technique, which laid the foundation for establishing and improving mathematical models and techniques of wood hot-press drying. The main existing problems in the research on wood hot-press drying and mathematical model describing heat and mass transfer were pointed out. Suggestions on the mechanism study and mathematical modelling describing heat and mass transfer were proposed. The application of hot-press drying to wood from plantations was also prospected, providing references for the efficient and high value-added utilization of plantation wood.
