● Heat source (for example, low pressure steam or thermal conduct oil) passthrough the sealed jacket. The heat will be transmitted to raw material to bedried through inner shell;
● Under driving of power, the tank is rotated slowly and the raw material inside itis mixed continuously. The purpose of reinforced drying can be realized;
● The raw material exists is under vacuum. The drop of steam pressure makesthe moisture (solvent) at the surface of raw material become saturation and willevaporate. The solvent will be discharged through vacuum pump an recoveredin time. The inner moisture (solvent) of raw material will infiltrate, evaporate anddischarge continuously. The three processes are carried out unceasingly andthe purpose of drying can be realized within a short time.
1.No deformed cracking: In tradition drying methods, it has wastes due to distortion, cracking and rot. Microwave infltrates to evaporate the interior moisture in short time and produce a spreading pressure to push moisture comes to the surface quickly.
2.Uniform drying: Its drying result is uniform moisture in horizontal levels of wood is absolutely same. Verically, moisture near surface is higher than the core which is good in aplication.
3.High eficiency and energy saving: Fast drying speed. Uniform and complete drying, no dstortin, no cracking and no hard- ening.Kills insects, insect proof, mould proof, rot proof for long storage time. High eficiency and lower energy about 30%.
