Characteristics and advantages of wood qualitative and balanced treatment vacuum drying equipment:
1. High frequency heating: in the high frequency drying equipment, the wood is in the middle of the high frequency polar plate, and the electric field directly penetrates the wood for uniform heating, while the high frequency only acts on the water, and the wood itself does not absorb the electric field. Therefore, the water is quickly heated and gasified. Due to the internal temperature and water vapor pressure, a pressure gradient is formed inside the wood, forcing the water in the wood to be discharged to the surface, The water vapor is discharged into the tank, so the high-frequency drying is heated from the inside to the outside, which is just opposite to the traditional steam or hot air heating. Therefore, the relative humidity of the wood surface is very large, eliminating the process of continuous water spraying in the drying process. At the same time, the heating is more uniform, fast and not easy to crack and deform.
2. Vacuum state: the boiling point of water in vacuum state is low, and the water in vacuum, qualitative and balanced drying equipment begins to vaporize when it is heated to 60 ℃, which achieves the purpose of drying at low temperature, greatly reduces the problem of wood cracking and deformation, and is especially suitable for the drying of more valuable wood sensitive to temperature. The effect of vacuum suction accelerates the drying process. The yield can reach more than 95%
3. The top of vacuum, qualitative and balanced drying equipment adopts hydraulic device, and the wood is dried in the compressed state, which plays the role of wood straightening.
4. In addition, vacuum, qualitative and balanced drying equipment has many characteristics such as sterilization, insecticidal and environmental protection, which will not be described one by one.
