Wood drying equipment can make good use of high temperature and hot air to dry wood quickly. Nowadays, there are still some people who do not use the equipment correctly. Improper use of the equipment will bring many bad consequences. Let me introduce the equipment to you. Consequences of improper use: excessive and uneven shrinkage of the wood surface, and shrinkage is often accompanied by internal cracks. The correction method is to use soft reference drying and appropriately reduce the drying temperature, which can prevent shrinkage to a certain extent.
Warping is a composite deformation, tile bending, bow bending, bending and torsion often occur at the same time, which makes the wood lose its use value. The correction method is to use saturated steam in an appropriate state to reduce the degree of warpage.
Cracking: According to the different cracking parts, it can be divided into three types: end cracking, surface cracking and internal cracking, all of which are caused by uneven drying and different evaporation rates of water in each part, resulting in local stress. The correction method is to adjust the drying benchmark of the equipment and slow down the evaporation rate of water.
Bending can be divided into bow bending (bending along the grain) and tile bending (bending across the grain) according to different shapes. The remedy is to stack the lumber correctly with spacers and place heavy objects on top of the stack. The wood drying equipment has strong scalability, and the design considers the production margin. Even if the output increases slightly, there is no need to replace the equipment. We should pay attention to the use of such a simple equipment, follow the correct steps, and maintain the equipment regularly to extend the Period of use.
