In tradition drying methods for wood, it has lots of wastes due to distortion, cracking and rot. Microwave infiltrates to evaporate the interior moisture in short time and produce a spreading pressure to push moisture comes to the surface quickly. Its drying result is uniform – moisture in horizontal levels of wood is absolutely same. Vertically, moisture near surface is higher than the core which is good in application.
Trials prove that microwave is more than 5% efficient because,
Fast drying speed (it takes only 15-25 minutes to dry from 30% moisture to 12%). Uniform and complete drying, no distortion, no cracking and no hardening. Kills insects, insect proof, mould proof, rot proof for long storage time. High efficiency and lower energy about 30%. Easy operation and automatic work to save labor. Safe sanitary and wood saving
