The present application relates to the technical field of artificial board preparation, and specifically discloses a wood
chip efficient hot
air drying device, which comprises a
drying cylinder and a hot air source, the center of the end surface of the
drying cylinder is provided with a disc, a hot air duct connected with the hot air source is arranged through the
drying cylinder, a hollow rotating
pipe is rotatably arranged on the outer wall of the hot air duct, a plurality of material scraping plates are uniformly arranged on the hollow rotating
pipe, a material dropping port is formed on one end of the material scraping plate close to the hollow rotating
pipe, and a
material scattering plate sealing the lower end of the material dropping port is rotatably connected to one end of the lower end of the material dropping port close to the hollow rotating pipe; the wood
chip efficient hot
air drying device changes the internal structure of the traditional drum dryer, so that the wood chips can be dried faster, the drying uniformity of all wood chips can be improved, the drying effect of all wood chips is ensured, compared with directly passing in the axial hot air, the
contact time of the hot air and the wood chips can be prolonged, and the
heat energy loss in the hot
air drying process can be reduced.
