摘要:

通过对日本人工林木材柳杉髓心方材进行系列高频真空干燥试验,掌握柳杉髓心方材的干燥特性及相应的高频真空干燥条件。结果表明:高频真空干燥前在常压下进行合理的蒸汽和过热蒸汽预处理,柳杉髓心方材可有效地提高干燥质量,尤其可防止开裂产生

关键词: 高频真空干燥, 髓心方材, 蒸汽和过热蒸汽预处理, 干燥质量

Abstract:

After a series of radio frequency/vacuum (RF/V) drying tests were conducted by using boxed-heart timber of Japanese plantation species, Sugi, the drying characteristics and corresponding RF/V conditions were investigated. The results of tests showed that before starting RF/V test, the pre_treatment methods with steaming and superheated-steaming under the atmosphere pressure were the effective ways to improve RF/V drying quality especially on reducing drying checks.

Key words: radio frequency/vacuum (RF/V) drying, boxed-heart timber, steaming and superheated-steaming pre-treatment, drying quality
