Some common questions and answers about wood veneer dryers!
|
|
When we use the veneer dryer, we often encounter various problems, and some questions about the equipment make us at a loss. Let the editor of Jinlun explain it in detail for you!
1. Why should wood be dried?
Fresh wood contains a lot of water, and it continues to volatilize in a special natural environment. Of course, the volatilization of moisture will cause the wood to appear dry shrinkage, cracking, bending deformation, mold and other shortcomings, which will seriously harm the quality of wood products. Therefore, the wood must be dried before being made into various wooden furniture. Proper drying solution can get rid of the defects of the wood, improve the structural mechanical compressive strength of the wood, and improve the production and processing characteristics of the wood.
2. Wood veneer dryer machine equipment-heating furnace?
Wood veneer dryer machine equipment must have three basic elements to complete the mandatory drying of wood: heating, wheel dehumidification and natural ventilation. The heating effect is obvious; the runner dehumidification is used to dry the natural environment with high environmental humidity required by some links to avoid wood cracking, deformation, etc.; the ventilation and cooling equipment must evenly pass the cold and humid air over each position of the wood pile to enable drying The moisture content of the wood afterwards is uniform. Simple wood talent "heating furnace" generally uses electric furnace gas to heat immediately or indirectly, and it is impossible to have an effective cyclone circulation system, and the environmental humidity cannot be adjusted or adjusted. This kind of simple machinery and equipment can obtain good drying results. It is very difficult.
3. Which is the key to machine equipment and processing technology?
Excellent machinery and equipment characteristics are the basis for drying wood dry timber and a prerequisite for the implementation of the drying process. Processing technology is important for wood veneer dryers. The wood veneer dryer process usually lasts for several days or even dozens of days. When to heat up and under what circumstances, the runner dehumidification is very important. Appropriate processing technology can be quality; under the premise of low calorie consumption, the wood can be dried at a fast rate, and poor processing technology will cause many woods to be reduced in grade due to drying defects and uneven moisture content. Therefore, machine equipment and processing technology are as closely related as the hardware configuration of an electronic computer and mobile phone software.

4. Is it necessary to accurately measure the moisture content of wood?
The moisture content of wood is one of the key parameters of the wood veneer dryer. The scientific research drying process is closely based on the moisture content of wood. When the wood moisture content is high, you must choose a lower temperature and higher environmental humidity; the wood moisture content is around 30% is the critical period, and the drying must be carried out gently; when the wood moisture content of different piles varies greatly , Must carry out a balanced solution. Without knowing the moisture content of wood, drying can only be carried out based on work experience. Because there are many types of wood, and the material properties are very complex, sometimes it is not reliable to dry wood based on work experience. The high-quality wood veneer dryer machinery and equipment should have the basic elements to accurately measure the moisture content of wood.
5. Is the automatic control system necessary?
Wood veneer dryer is a long process. During the whole process, the drying equipment must continuously adjust the environmental parameters in the drying kiln according to the change of wood moisture content, so that the wood can be dried well. Manual intervention in this process not only requires the operator to have more, until the drying is completed. For manufacturers with little work experience, especially for manufacturers with high drying quality regulations, it is essential to be equipped with a fully automatic control system.
6. Wood veneer dryer, the drier the better?
Wood placed in a certain natural environment, after a sufficient period of time, its moisture content will tend to an equilibrium value, which is called the equilibrium moisture content of the natural environment. When the moisture content of the wood is higher than the equilibrium moisture content of the natural environment, the wood will get rid of moisture, but will absorb moisture and swell. Therefore, the wood veneer dryer should be moderate, not the higher the dryness.
The above are some questions and answers about the veneer dryer. I hope it will be helpful to everyone. Friends who want to know the price can call our customer service hotline at any time!
