| Abstract: | Based on the experimental results of the infrared drying of a 30 mm plank, this paper studies the characteristics of the three phases of drying and its application. The measurement data and the simplified drying kinetic equations have been analysed. The use of optimized kinetics operational condition ensures the saving of time, energy and keeping product quality in the infrared drying. The drying process can be studied by new nondimensional numbers equation and three phase theory. |
