Vacuum Drying Technology for Plantation Larch Lumber
A series of vacuum drying tests were conducted on timbers of plantation larch.The authors studied the effect of vacuum pressure(200,400 mmHg) and initial medium drying temperatures(61,8,8 ℃) on the drying rate and moisture content deviation of the specimens.The results showed that the drying rate and moisture content deviation of the samples,were optimized by vacuum drying technology.By increasing the initial temperatures,the drying rate increased,but the drying rate decreased when the drying medium temperature increased.
