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
