The control of the wood drying process is a very important part of the drying process. It is directly related to the quality of the wood drying. Good control is the organic combination of the operator and the control equipment. Otherwise, no matter how advanced the control system is without the correct operation of the operator, it will be No practical effect.

The most important thing in the wood drying process is to make the parameters in the drying equipment as close as possible to the drying benchmark. The most important parameters in the wood drying benchmark are wood moisture content, air temperature and humidity.

The factors affecting the temperature and humidity stability of humid air are as follows. (1) Factors affecting the stability of humid air temperature control during the drying process. By controlling the steam in the heater to control the humidity of the humid air, the stability of temperature control mainly depends on whether the area of ​​the heater configured in the wood drying chamber matches the volume of the wood to be dried.

Mahogany furniture is a kind of high-end durable consumer goods, and its production is a very particular knowledge. The production of any set of mahogany furniture needs to go through material selection, wood drying, woodworking molding, coating and painting, etc. to complete. Among them, the moisture content of furniture materials and wood drying treatment are the most important, because this is one of the basic requirements for the production of mahogany furniture, otherwise the finished furniture will have cracking and deformation of the panel, loose tenon structure, moth-eaten and mildew on the sideboard, etc. Therefore, the quality of furniture cannot be guaranteed.

The heaters commonly used in the drying room are: cast iron ribbed tube heaters, smooth tube heaters, spiral plate heaters and rolling plate heaters.

(1) The wood to be dried in the same drying room must have the same species or similar material properties, the same thickness, and the initial moisture content is basically the same. (2) Be careful not to damage the door, wall and indoor equipment when loading materials. The materials should be parked or stacked stably and neatly.

According to the drying quality and drying time of the dried wood, the performance of the drying standard can be evaluated, and the following three indicators are used to evaluate the use effect of the drying standard.

During the drying process of wood, in the process of water evaporation in wood, due to the different combinations of various water in wood and wood, the properties of water in wood at each stage are different, and the properties of wood corresponding to this are also different. Therefore, in the wood drying process, the evaporation process of water in the wood should be reasonably controlled, so as to improve the drying speed as much as possible on the premise of ensuring the drying quality of the wood.

When wood is drying, the drying defects that often occur in wood drying include: internal cracks, surface cracks, end cracks, bending, shrinkage, charring, severe surface discoloration, and uneven drying.

Whether the sawn timber accumulation is reasonable or not directly affects the dry quality of the wood, and its importance cannot be ignored because the sawn timber accumulation operation is simple and heavy. There are some requirements for stacking operations as follows:
