This project consolidates around the design and implementation of a prototype for wood drying experimentation; based on a medium power RF circuit coupled to a drying platform it looks for to validate the endogenic heating phenomena by dielectric means. As it was conceived for research purposes, it is rugged enough and it has the proper protected for user safety and technical endurance; due to these considerations, vacuum tubes were used in the design and exposure to RF radiation is time controlled as well, including manual and automatic operation. This opens the gap for future research around energy efficiency, quality and operation of this type dielectric drying vs. conventional drying methods timber.
