Drying characteristics of MasCon Pine (Pinus massoniana), under different microwave-vacuum conditions, were studied systematically in this paper. The results showed: 1) The process of microwave-vacuum wood drying could be divided into three stages: a short period of accelerating drying rate, a long stable period drying rate, and a period of decelerating drying rate, with the second period occupying 50% of the whole drying process; 2) Increasing initial wood moisture content and microwave radiation time increased the drying rate of wood ac...
