This paper reviews research and application of practical wood drying technologies in China during the last two decadesIt covers pre-drying treatments,drying techniques and equipment and energy conservationSuggestions and remarks for further development and application of advanced wood drying technology in China are presented

In order to enhance the quality of woodwork, a new drying equipment of two-stage compression high temperature heat pump was developed. This heat pump drying equipment is capable of switching between one-stage compression and two-stage compressing. Components and working principle of two-stage compression high temperature heat pump equipment were introduced in this study. Drying experiment was conducted with Pinus massoniana plates. The results show that this equipment had great energy saving performance and the average energy recycling rate could be achieved beyond 28%. Meanwhile, by means of two-stage compression and utilization of new refrigerant-R245fa, condensing temperature and heating temperature reach 120 and 110°C, respectively.
