Vacuum Kiln
Radio Frequency Vacuum Kilns vs Conventional Wood Dryers Wood that is over 10 cm thick generally falls into the large section category It is difficult to completely dry this type of wood using conventional drying methods like steam drying and hot plate drying because both of these methods adopt a heat conduction method to heat the wood
About
Radio Frequency Kiln Operating Principles: Wood is loaded into the kiln chamber and sandwiched between an anode and cathode plate A hydraulic load is placed on the pack to ensure that there is surface contact between the wood layers and the plates The wood is then subjected to a steady supply of radio waves under vacuum conditions
