Based on the mechanism of moisture and heat transfer in wood during microwave-vacuum drying (MVD), an one-dimensional mathematical model to describe the process of wood MVD was established and verified by experiments in this research. The results showed that the process of wood MVD experienced three distinct periods: Rapid warming-up with accelerating drying period (I), a constant temperature and constant rate drying period (II), and a heating-up with falling rate drying period (III). Compared with conventional hot air drying, the second period made up the bulk of the whole drying process. The...
