The invention discloses a wood conditioning method. The method comprises following steps of immersion treatment, primary heating and humidifying treatment, primary
drying, primary cooling, secondary heating and humidifying treatment, secondary
drying, secondary cooling and ventilation
drying. According to the wood conditioning method, the high-temperature and low-temperature alternative drying manner is adopted to reduce the wood water containing rate, through immersion treatment,
ammonium bicarbonate is guided into the wood, due to alkalescence of an
ammonium bicarbonate solution,
cellulose on the wood
cell wall can be swelled up, introduction of subsequent heat and water flowing can be facilitated, according to high-temperature and high-
humidity treatment, overheat water steam is used for forming
partial pressure so as to move water out of the wood, through cooling,
temperature gradient is used for diffusing water to the outer portion, the high temperature drying and the low temperature drying are alternatively carried out, the water containing rate of the wood is reduced to the proper range, the anti-
mildew anti-
corrosion property of the wood can be increased, consumed time is short, and
energy consumption is small.
