1.Character
High frequency wood dryer applies both high frequency and vacuum condition. HF heating: high frequency power acts only on the moisture of wood, it penetrates the wood where there is water or mositure, there is high frequency power. So it dries fast and uniformly.
Vacuum condition:
1)At vacuum condition, the water is vapor at a very low temperature, so it eliminates the sparking or splitting problems for hard wood, especially for the type of extremely hard wood that likely to spark if drying temperature is too high.
2)Further more, vacuum condituon creates a minus pressure, this pressure sucks the water or moisture out of wood fast.
