According to experiment for rubber wood, microwave dryer is observed to have a higher value than that of hot air, resulting in higher energy requirement for drying process. So what kinds of wood material are suited for microwave technology?

Firstly, high value-add furniture wood is widely used by microwave dryer. Microwave dryer minimize wood discolor and prevent wood cracking during drying process. Lower moisture content of high valued wood is quickly eliminated by microwave wave throughout a continuously tunnel model. Accurately control drying temperature and moisture content are the main advantages, which other drying solution hardly achieve it. The whole drying process is precisely governed by PLC system to assure wood value

Secondly, Using adhesive to sticking wood is also suited for microwave dryer. Laying the adhesive wood on the conveyor belt, microwave energy are capable of exciting glue water molecular so adhesive wood is uniformly dried out to the next stage treatment, maximum saves drying time and cost

Thirdly, Hardwood is also available to use microwave dryer. Microwave wave directly penetrates high density wood compared to steam and hot air drying solution. Therefore, microwave could fast drive moisture from the center of hardwood to the surface, uniformly heat up wood both inside and outside.

In addition, microwave dryers are also applied for industrial scale second time wood drying that has the lower moisture content, water-painted wood, normal painted wood and plywood material. Industrial Microwave is an environmentally friendly machine which does not produce any pollution and unexpected material. 

“Microwave processing allows timber to be impregnated with resins or preservative to improve its strength, stability and durability,” says Professor Peter Vinden, CEO of CRC Wood Innovations. “Microwave technology enables acceleration of preservative treatment to a few minutes, and generates a more environmentally friendly product.”
