RFV Drying of Eucalyptus nitens juvenile wood

Wood drying is an important process for adding value and manufacturing innovative products. Emergent species such as Eucalyptus nitens are still developing their potential as solid wood and requires further research and scientific knowledge to solve certain drying problems for adding value to that wood. Eucalyptus nitens wood is inherently difficult to dry, because of the natural propensity to internal checking, collapse and shrinkage, then lumber recovery after industrial drying of eucalyptus is very low. This work aimed to study the wood quality of Eucalyptus nitens juvenile wood of 13, 26 and 50 mm thickness after radio-frequency vacuum drying. The drying cycles were performed using a radio-frequency vacuum equipment of 3 m3 capacity. The results showed that radio-frequency vacuum drying of Eucalyptus nitens juvenile wood improve the wood quality for solid wood products, it were reduced the intensity of the internal intra-ring checking, surface checking and collapse.
