The cutting technology of rotary veneer dryer is widely used in raw material processing, product processing and molding. Cutting is to separate the wood material into several individual shapes and reorganize according to the established form to form a board. This treatment can optimize the shrinkage, swelling and anisotropy of wood.
The larger the individual of cutting, the higher the mechanical strength of the combined plate. On the contrary, the smaller the number of individual slices, the better the homogeneity of the plates. The shape of the particle will have a great influence on the physical and mechanical functions of the particle. At the same time, the shape of the cut fiber also affects the strength of the product. The quality of the artificial panel and the grinding process will also be affected.
The drying process of veneer dryer includes veneer drying and particle drying. According to the different drying methods of dry and wet fiberboard, it is divided into dry fiberboard and wet fiberboard heat treatment. There is a certain difference between boring process and wood boring. The dry process of wood-based panel is measured by the relative humidity of dry carrier, especially to prevent the occurrence of dry stress.
Compared with the boring process of wood-based panel, the boring process of wood-based panel is carried out in the required high-temperature, high-speed and continuous environment. After the heating stage is finished, it does not stop, and immediately enters into the process of deceleration and boring. Steam and incineration gas are the primary sources of heat for dryness. Compared with infrared dryness, steam drying only consumes 4200-5000kj per 10006 evaporated water, while evaporated water consumes 1.5-3 times of heat per 10006 evaporated water. High frequency dryness has a series of advantages, such as fast drying speed and even water content, but the defect is high cost. But it is feasible to use it in combination with steam drying.
I hope the above information about veneer drying process after wood cutting can help you, thank you.
