Wood Drying
Drying of B. Bamboos in dehumidifier kiln
The primary reason for drying of wood is to bring down its moisture content to a level as will later be used
in service condition to minimize the dimensional changes (or movement) in the final product. This is done in
an enclosure called seasoning kiln in controlled way to avoid defects like warping, splitting, cupping etc.
Drying of wood improves properties including mechanical properties, dimensional stability and also enhances
service life of wood against biodegradation. The microwave wood dryer system
Our current research is focused on studying drying behavior of plantation timbers of India using
dehumidification dryer and microwave dryer.
The efficiency and drying behavior of six plantation timbers (E. teriticornis, G. robusta, H. brasiliensis,
A. auriculaeformis, T. grandis and C. equistifolia) was studied using a desiccant based dehumidification wood
dryer. Energy requirement in reducing moisture by one percent below FSP was nearly two to three folds as
compared to above FSP in all the species
Drying behavior of some of the wood and bamboo species is being studied using a microwave dryer. Effect of initial moisture content, microwave intensity and exposure duration on drying rate and drying quality is being investigated.
