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.

The basic principle and drying essence of dehumidification drying and conventional drying are the same. Both rely on the convection heat exchange between the hot air in the wood drying room and the wood to be dried, and the air heats the wood and absorbs the moisture evaporated from the wood. The main difference between the two is the method of dehumidifying the air.

Surface cracks are longitudinal cracks that occur along the wood rays on the outer surface of sawn timber (usually the outer cut surface of a chord-cut board). It is caused by excessive surface tensile stress in the early stage of drying

The discoloration of wood, simply put, is the color change on its surface due to the action of the environment (sunlight, oxygen, moisture, temperature) and microorganisms (fungi).

The discoloration of wood, simply put, is the color change on its surface due to the action of the environment (sunlight, oxygen, moisture, temperature) and microorganisms (fungi). Discoloration can occur on logs, sawn timber, and wood products.

What are the basic concepts of wood drying, do you know?
