The authors reviewed the present research status on lumber energy-saving drying technology,and summarized the recent research achievements of wood energy-saving drying.They considered that solar drying technology was suitable for pre-drying,and that phase change thermal storage was an effective way to solve the intermittent solar drying problem.A Solar-heat pump and a solar-conventional combination were ideal drying processes.A dehumidifier was commonly used in heat recycling and it was found that it could save up to 40%drying energy.The oscillating-flow heat pipe applied in heat recycling was cost effective equipment and could save 20%～50% drying energy.
