Changing the wood drying game
How does a RF vacuum kiln work?
Our process is naturally different from conventional kilns, and far more efficient. 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 (no spacers needed).
After loading, the wood is then subjected to a steady supply of radio waves under vacuum conditions, creating an electro-magnetic field which polarizes or aligns the water molecules within the wood.
The continuous movement of the water molecules in the ever-changing electro-magnetic field creates heat energy which is then stored in the wood. As the temperature of the wood increases, the cell water is converted to steam under low temperature and expelled from the vacuum chamber.
Radio frequency technology like ours is used in many industries worldwide, such as molding plastics, gluing or sealing products such as wood, shoes and handbags, processing food items, and for medical use such as MRIs.
Our generators run at 6.78 MHz, which is standard in commercial applications. It is safe and efficient and will not harm people or products. Think of it like using your microwave instead of your conventional oven to heat food. The same principles apply; radio waves are simply less aggressive and penetrate wood better.
The RF difference
An impressive finished product
The RF drying process heats from the inside out, causing the wood to dry evenly and allowing the external surface of the wood to remain wet until the end of the drying cycle.
Maintaining a wet outer surface for as long as possible significantly reduces checking and defects generally associated with kiln drying.
