How to dry birch plywood during production

The drying process of birch plywood is a critical part of the production process, which directly affects the quality and performance of the final product. The process begins with the initial processing of the wood chips, first cutting the wood into the required thickness, and then strictly screening and grading these wood chips to ensure that they meet the production standards in terms of size, thickness and texture. The fine processing of this step lays the foundation for the subsequent drying process, because the consistency of the wood chips is the key factor to achieve uniform drying and high efficiency.

After entering the drying stage, the wood chips are fed into efficient drying equipment. These equipment usually use advanced hot air circulation technology to create an optimal drying environment for the wood chips by precisely controlling the temperature, humidity and air flow rate. During the drying process, hot air will continue to penetrate the wood chips, accelerating the evaporation of the moisture inside them. At the same time, the built-in humidity control system of the equipment can monitor and adjust the humidity level in real time to avoid cracking or deformation of the wood chips due to over-drying.

To ensure the best drying effect, manufacturers will fine-tune the drying process according to a variety of factors such as the type, thickness and initial moisture content of the wood chips. For example, for thicker wood chips, it may be necessary to extend the drying time or increase the drying temperature, while for wood chips with a higher moisture content, a gentler drying method is required to prevent the water from evaporating too quickly, causing internal stress concentration, which can cause deformation problems.

During the drying process, the placement and turning of wood chips should also not be ignored. Reasonable placement can ensure that the hot air penetrates the wood chips evenly, thereby improving drying efficiency; while regular turning helps prevent the wood chips from deforming due to uneven heating for a long time. Therefore, manufacturers usually use professional drying racks and turning equipment to ensure that the wood chips remain in the best condition throughout the drying process.

In addition, advanced monitoring technology also plays an important role in the drying process. These monitoring devices are connected to the drying system and can track the drying progress and moisture content changes of wood chips in real time. Through monitoring data, manufacturers can adjust the drying process in time to ensure that the wood chips are dried in the best condition and minimize production risks.
