Abstract
The invention relates to the field of wood processing, in particular to a wood drying processing device. The wood drying processing device comprises a feeding support, a guiding rail, a pressure vessel, a steam pump, a water tank, a steam pipe, a returning pipe, a vacuumizing device, dehumidifying devices, a decompression valve, a material pressing device and a control cabinet. The guiding rail is divided into two sections; one section of the guiding rail is fixed at the bottom of the pressure vessel, and the other section is arranged in front of a feeding inlet of the pressure vessel. The steam pump is communicated with one end of the steam pipe, and the other end of the steam pump is communicated with one end of the returning pipe. The other end of the returning pipe is connected with the water tank. The vacuumizing device is connected with the pressure vessel. The control cabinet controls the operation of the steam pump, the vacuumizing device, the material pressing device, the dehumidifying device and the decompression valve.
