The application discloses a kind of solid wood board hot-pressing drying method, belong to timber processing technical field.Solid wood board hot-pressing drying method includes the following steps: solid wood board is placed on hot press;Hot press includes the upper pressing plate and lower pressing plate oppositely arranged along vertical direction, and left side pressing plate and right side pressing plate arranged along horizontal direction;Solid wood board is preheated;Upper pressing plate and lower pressing plate are heated to hot-pressing temperature;After upper pressing plate and lower pressing plate reach hot-pressing temperature, control upper pressing plate and lower pressing plate to exert radial pressure on solid wood board, left side pressing plate and right side pressing plate exert chordal pressure on solid wood board;When the moisture content of solid wood board reduces to below moisture content threshold, pressure is released and dried solid wood board is taken out.The application simultaneously exerts radial and chordal pressure during drying process, combined with the synergistic control of pressure and temperature, effectively controls wood deformation and stress during drying process, thereby inhibiting wood shrinkage, cracking and deformation problems.
