Why is pine the most difficult to dry?

Pine is considered one of the most difficult woods to dry, mainly due to its wood structure and composition.

1. Uneven density: Pine fibers are relatively fine and soft, resulting in uneven density inside the wood. This makes the wood dry at an inconsistent rate, prone to cracking and warping.

2. High moisture content: Compared with other woods, pine has a higher moisture content. It takes longer for the moisture inside the wood to evaporate completely. If the moisture is removed too quickly, the surface of the wood dries too quickly while the interior still contains moisture, which can cause the wood to crack.

3. High resin content: The resin content in pine is relatively high, and the resin plays a hindering role in the drying process of the wood. The resin forms a film layer that prevents the loss of moisture, making the pine dry slower.

Therefore, in order to obtain high-quality dried pine, it is necessary to adopt appropriate drying methods and strictly control parameters such as humidity and temperature during the drying process to avoid problems such as cracking and warping.
