Abstract:
      A kinetic model of water evaporation on the surface of paper was derived based on the boundary layer theory in the current study. In addition, the mass and energy balance model was established for paper drying process. Using numerical analysis method, a paper drying process of corrugated paper machine was simulated, and the paper temperature, paper moisture, and the drying rate during paper drying process were calculated, three stages during paper drying process were analyzed quantitatively: the temperature-rising drying stage (1#~4# cylinder), the drying at constant rate (5#~39# cylinder) and decelerating drying stage (40#~48# cylinder). When paper moisture dropped to 0.22 kg/kg, the paper entered into the decelerating drying stage.
