The invention discloses a wood dryer and belongs to the technical field of wood processing equipment. The wood dryer comprises a drying chamber surrounded by a shell, a door used for opening or closing a feed inlet is arranged on one side of the shell, a plate containing frame which is driven by a power machine to rotate is arranged in the shell and comprises a core tube, multiple support fin plates and a supporting net plate, the core tube faces the door transversely, the support fin plates stretch out of the surface of the core tube in the radial direction, and the outer ends of the supportfin plates are covered with the supporting net plate. A draught fan is arranged outside the shell. Each support fin plate is provided with two opposite panels which are respectively provided with multiple air outlet holes, and an air channel is arranged between the two panels. An air outlet of the draught fan communicates with the air outlet holes through the core tube and the air channels. The wood dryer can solve the problems that an existing wood dryer has uneven air supply, wood veneers piled on the surface are prone to crazing or curling, while wood veneers piled in the middle and at thebottom are difficult to dry, and as a result, energy consumption is high, and the energy utilization rate is low.
