HF and Vacuum condition:
As HF heats from inside, so the core of wood will dry first, and then gradually to the outside, then the vacuum pump extract the moisture out from inside thus make the surface of wood is always wet, for some hard wood if the surface is dried quickly, there will be spark on the surface and leave permanent defect on the wood, but HF vacuum condition will totally eliminate the problem.

3. Temperature control:
