The invention discloses a three-dimensional air supply drying air flue system. The three-dimensional air supply drying air flue system comprises a box, a first air valve, a first air door assembly, asecond air valve, a third air valve, a second air door assembly and a fourth air valve. Through closing of the first air door assembly and the second air door assembly and control over opening and closing of the first air valve, the second air valve, the third air valve and the fourth air valve, an air path of a drying inner cavity serves as a penetration air supply air path. Through closing of the first air valve, the second air valve, the third air valve and the fourth air valve and opening of the first air door assembly and the second air door assembly, the air path of the drying inner cavity serves as a parallel air supply air path. Through adjustment of switchover of the first air door assembly or the second air door assembly in the preset totally-opened state, the half-opened state and the closing state, the
