Technical Field

[0001] This utility model relates to the field of composite board drying technology, and in particular to a rapid drying equipment for bamboo and wood composite boards. Background Technology

[0002] Bamboo-wood composite panels, a material combining the properties of bamboo and wood, are widely used in furniture manufacturing, interior decoration, and construction formwork. The drying process is crucial in the production of bamboo-wood composite panels. On one hand, proper drying removes excess moisture from the panels, reducing their moisture content and preventing deformation and cracking during subsequent use, thus improving product quality and stability. On the other hand, proper control of the drying process helps improve the physical and mechanical properties of bamboo-wood composite panels, such as enhancing their strength and hardness. With the continuous growth of market demand for bamboo-wood composite panels, drying equipment is therefore essential.

[0003] Existing drying equipment is prone to damage and aging of its components due to the harsh environment of high temperature and high humidity during long-term operation. In addition, the heating elements and ventilation ducts of some drying equipment are compactly arranged, making it difficult for maintenance personnel to disassemble and replace them once a failure occurs. At the same time, the hot air of the drying equipment is usually blown in from one end during the drying process, which can easily lead to uneven drying of bamboo and wood composite boards. Therefore, a fast drying equipment for bamboo and wood composite boards is needed to solve the above problems. Utility Model Content
