The temperature of wood drying equipment directly affects the moisture content of formed wood. Dryer heating plate is generally three groups, each group is composed of four, five and six heating plates. Each heating plate of steam heating dryer is equipped with pressure regulating valve, which is used to adjust the steam pressure entering the heating plate, so as to change the temperature of the heating plate and ensure the production of high-quality wood. Among them, we need to pay attention to the following details.
1. Before entering the wood drying equipment, the moisture content of the wood will change due to the different storage time. In addition, the moisture content of paste liquid on the single side machine will change after a period of time, which will lead to the change of wood board moisture content.
2. Before compounding, it is necessary to preheat the wood board for a second time. The preheating process should also be adjusted according to the water content, that is, by adjusting the active paper guide roller, changing the preheating area, so as to achieve the purpose of adjusting the moisture content of wood board.
3. The purpose of drying is to ensure the curing of paste solution and adjust the moisture content of wood board at the same time. The two should not be neglected. Therefore, the pressure reducing valve should be adjusted at any time according to the moisture content of single-sided wood board, so that the wood drying equipment can reach the appropriate temperature, which not only ensures the paste liquid curing, but also ensures the moisture content of the formed wood board is moderate. In addition, the length of cooling section of wood drying equipment has a certain impact on the moisture content of wood panel. If the cooling section is too short, the moisture can not volatilize in time, so it is necessary to increase the local air supply to achieve the purpose of drying.
3. If the ideal condition can not be achieved by conventional temperature adjustment, the method of changing the speed can be tried. That is, when the water content is too high, slow down the speed; when the water content is too low, increase the speed.
When the wood drying equipment is working, it can not be stopped until it is absolutely necessary. If the wood drying equipment is shut down, the water on the wood drying equipment will be completely evaporated, resulting in the scrapping of all wood panels.
