Title:
PRESSURE REDUCTION TYPE DRYING MACHINE AND METHOD OF DRYING WOOD USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2006/025328
Kind Code:
A1
Abstract:
A pressure reduction type drying machine and a method of drying wood using the drying machine capable of uniformly drying a dried material in a short time, preventing the dried material from being damaged, and reducing a power consumption by repeatedly performing pressure reduction and heating/humidifying during drying and imparting vibration to the dried material in pressure reduction. In the drying machine, at least a ceiling part and side wall parts are formed in an outwardly swelled generally circular arc shape, and reinforcement ribs are disposed between outside walls and inside walls at a ceiling part, side wall parts, and a floor part along the outer periphery of the inside walls parallel with and/or perpendicular to the longitudinal direction of a drying compartment. The pressure reduction type drying machine thus provided can provide excellent reliability, productivity, and energy saving property, and particularly when the wood is dried, does not almost cause defects such as warpage, internal cracking, crazing, shrinkage, bending, and surface cracking, can develop luster on the surface of the wood and has no discoloration and still has slight odor after drying, can provide high commodity value since a humidity in a building can be permanently controlled according to an environment after the construction, and can effectively use moisture contained in the dried material such as the wood as a byproduct by extracting it without waste.
