This is evident that most of the time woodworking professionals get confused on improving their drying program. Incoplan gives a quick solution and delved deep into the matter.

6 outstanding tips to improve the drying program from Incoplan:

The success of wood drying resides in attention to detail. Loading the drying kiln correctly, and precisely managing the airflow are two practices , together with a proper drying software, that make a drying program successful.

• Lumber positioning: When loading lumber, it is important to arrange it in a way that the airflow does not directly hit the ends of the boards. To prevent the air from descending directly down the stack, it is recommended to have a spacious area.

• Horizontal flaps or deflectors: In the case of tunnel cells, semi-circular flaps or revolving deflectors of 300 mm width can be used to direct the air at different heights.

• Horizontal baffles: These double devices, usually made of rubber, are placed between the lumber and the attic to prevent the air from circulating aimlessly. They typically have heights of 500 or 1000 mm, or intermediate heights, and must touch the stacks for at least 10 cm to function correctly.

• Vertical flaps: Devices measuring 460 mm and 750 mm in width are strategically placed on the sides to obstruct airflow and stop it from passing over the board ends. When stacks are situated next to one cell side, it’s possible to deploy two flaps—one at the front and another at the back—to exclusively block the side that is exposed.

• Corners deflectors: These devices with a radius of 300 mm are placed on the corners of the cells to allow the air to slide and avoid the friction of the 90° angle. This improves the airflow circulation inside the cell and provides better spacing.

• Space between the stack and the attic: To ensure optimal drying of the wood, particularly softwood which benefits from significant airflow, maintaining a minimum gap of 50 cm between the stacks and the attic is advisable. This spacing facilitates proper circulation of air and contributes to the even drying of the boards positioned higher up.

These extremely helpful suggestions will help a professional to create personal best practices to achieve his desired result.
