When it comes to wood, this process is applied to reduce the moisture content in the wood to a specific level, thus making it more workable and less likely to warp or shrink after it’s been used.
The process of kiln drying begins with stacking the wood in a chamber known as the drying kiln. The arrangement of the wood inside the kiln plays a pivotal role in ensuring an even distribution of heat and airflow. Once stacked, the kiln’s temperature, humidity, and ventilation are carefully controlled to ensure optimal drying conditions for the type of wood in question. This control over the environmental conditions within the kiln allows for precise management of the drying process.
The next step involves gradually increasing the temperature within the kiln. This causes the moisture in the wood to evaporate. The steam generated is then expelled from the kiln via vents. It’s crucial to maintain an appropriate balance between temperature and humidity during this phase, as too quick a removal of moisture can cause cracking or splitting in the wood.
The final phase of kiln drying is known as conditioning or equalizing. During this stage, any remaining moisture within different areas of the wood is balanced out to prevent future warping or distortion. Once this phase is complete, the wood is ready for use.
Overall, kiln-dried wood provides several advantages over air-dried variants. The most important among these are its dimensional stability and resistance to fungi and insects. Additionally, since most of the moisture has been removed, kiln-dried wood weighs less, making it easier to handle and transport.
So, when someone asks, “What does kiln dried wood mean?” you can now confidently explain that it refers to wood that has been carefully dried in a controlled environment to reduce its moisture content. This makes it more stable and resistant to issues that can often plague untreated or air-dried wood, such as warping and insect infestation.
