PDF Radio frequency vacuum drying of wood. I

A one-dimensional mathematical model to describe the transport phenomena during continuous radio frequency/vacuum (RF/V) drying of thick lumber was developed from general conservation equations.

Radio frequency vs. super steam vacuum

RF-VAC has been used to dry softwoods and hardwoods, green to 6% MC, green to 20% MC (followed by normal kiln drying--this worked well), and also 25% MC to 6% MC. The results have been mixed, with the manufacturers often not understanding the quality requirements for kiln-dried wood.
