HF Vacuum Dryer manufacturers take you to understand the advantages of high frequency vacuum drying and other drying methods
timer : 2022-03-15
The following HF Vacuum Dryer manufacturers analyze the advantages of high-frequency vacuum drying and other drying methods:
Compared to traditional wood drying methods:
Mainly heat conduction drying (such as steam drying kiln, hot air circulation drying kiln, etc.) is relatively inefficient, because heat conduction drying is heated on the surface, and the heat is slowly transferred to the core, which means that the surface temperature for a long time. High, the core temperature is lower, which is the opposite of high-frequency heating. As we all know, the thermal conductivity of wood is low, so the drying time is longer. At the same time, another defect brought about is that the surface temperature of the wood is finally high, and the surface is excessively high. Drying, the HF Vacuum Dryer manufacturer tells you that these two points will cause cracking on the surface of the wood, and due to the uneven characteristics of heat conduction, it will also lead to changes in the stress of the wood and the problem of bending and deformation of the wood.
Compared to microwave drying:
Microwave is an electric field with a higher frequency than high frequency. As mentioned earlier, the higher the frequency, the faster the heating speed, and the shallower the heating, so microwave drying is more suitable for drying thinner boards or wood, HF Vacuum Dryer manufacturer told Because the microwave heating speed is fast, the surface of thick wood will be quickly heated, and the microwave electric field is difficult to radiate to the wood core, so poor control can easily lead to surface cracking or even surface carbonization or burning.
Compared with ordinary vacuum drying:
HF Vacuum Dryer manufacturers tell you that conventional vacuum drying mainly adopts the heating method of hot plate, that is, the wood is placed in the middle of the hot plate, and the hot plate is hollowed with heat-conducting oil or steam hot water. It can ensure that the wood is dried at a lower temperature, However, this drying method is still heat conduction heating, which still cannot ensure that the thick wood will not crack or deform during the drying process.
