Wood Internal Stress at Different Drying Stages The internal stress changes during wood drying can be divided into four stages. At the beginning stage of drying, the wood has not yet produced stress, and the moisture content of each part of the wood is above the fiber saturation point. If the test piece is cut from the middle of the material, the test piece is sawn into a comb shape, and the height of each tooth is the same as the sawn tooth. The original size before opening is the same. If the test piece is cut into two halves, each piece remains straight, which shows that there is no moisture content stress and no residual stress in the wood.

Thermally modified wood namely charring wood, carbonized wood is through carbonization processing timber, carbonization, carbon under the word is a fire, as the name suggests, there is no water in the water must satisfy the condition of high temperature, wood strength for protection, control of coking process, must have a protective medium.

CHIQIN Company is a company specializing in the production of various wood drying kilns and food drying kilns.  Safe production, reduce casualties and property losses has been the most important work of enterprises.

There are various types of drying equipment, including hot air drying equipment, vacuum drying equipment, freeze drying equipment, microwave drying equipment, spray drying equipment and rotary drying equipment. Each type of drying equipment has its unique working principle and application scenarios, which can be selected based on the characteristics of the material and drying needs.

Microwave drying of wood is a new technology that has been increasingly used in domestic and international markets in recent years. Compared with traditional drying methods, microwave drying equipment has a series of advantages such as uniform heating, fast drying speed, no deformation, no cracking, good quality, and is conducive to continuous and automated production.

1. Circular drying method This method is mainly applicable to wood such as Korean pine, Masson pine, and spruce. When operating, the wood needs to be divided into two parts: one part is placed in the center of the drying kiln, and the other part is placed around the drying kiln. This method can make the wood dry more evenly.

Using ThermoWood in place of regular wood presents several advantages, including but not limited to: Durability: As the wood is treated and becomes more resistant to the effects of insects, decay, and rot, ThermoWood can be used in a variety of outdoor applications without fear of degradation from weather exposure.

To ensure the smooth progress of the wood drying process, it is necessary to conduct a systematic inspection of the facilities in the drying room before each drying, especially the internal facilities. Otherwise, if problems occur during the drying process, it will seriously affect the production cycle and drying quality of wood drying, and also have an impact on the service life of the drying equipment. The equipment inspection before drying mainly includes the inspection of the various systems that make up the drying chamber.
