Title:
DRYING METHOD FOR WOOD OR THE LIKE
Document Type and Number:
WIPO Patent Application WO/1991/007261
Kind Code:
A1
Abstract:
This invention relates to a drying method for wood and the like which comprises conducting impregnation treatment by allowing a plant manufactured lumber to be impregnated with an organic impregnant and subjected to a hydrothermal reaction (hydrolysis), fitting an acoustic emission sensor to the lumber or the like thus subjected to the impregnation treatment, detecting an acoustic emission which the lumber or the like generates with the change of their wood structure as a signal, forecasting cracks in the lumber or the like by data-processing the signal and carrying out heat treatment while controlling the atmosphere using temperature and humidity as operation factors on the basis of the forecast data so that no cracks occur in the lumber or the like. The present invention relates also to a drying method of lumber or the like which is characterized in that heating and drying are carried out after the lumber or the like is impregnation treated with an organic impregnant.
