Bamboo and wood products require drying and insect control to prevent cracking, shrinkage, and infestation in the usage environment. Traditional drying mainly involves prolonged drying with hot air kilns (ovens). Both bamboo and wood have longitudinal fiber structures, and during traditional heating, the lateral thermal conductivity of the wet material is particularly poor. It takes a long time to dry the center to the required level, and due to the differences in fiber structure and texture, the heating is uneven in all directions, leading to cracking and deformation of the material during the drying process, with a high rate of waste products. Additionally, it is very difficult to further dry the material once the moisture content drops below 10%, necessitating the adoption of a new drying method.

Utilizing the microwave heating characteristics, bamboo and wood products can be dried using microwave, overcoming the drawbacks of traditional heating and drying methods. Additionally, while drying with microwave, the microwave also has a strong insecticidal effect on the bugs and eggs in bamboo and wood products. Therefore, combining microwave drying with insecticidal treatment is an ideal solution.
