The wet wood medium located in the electrical field. The polarized water molecules become dipole. With millions of times
direction change of electrical field per second, the molecules bring in very high temperature due to friction. Inside temperature
is higher than wood surface because heat distributed on the surface. At the same time, the tank inside is negative pressure. Due
to the function of temperature and pressure difference, the moisture in the wood core transfer from inside to surface rapidly.
Fast engineered wood HF hot press is using high frequency heating to shorten the processing time. It can make production more efficient.
