While my country's wood drying industry is in line with international standards and developing rapidly, there are still some problems that cannot be ignored, mainly in:

There are many ways to dry wood, how many do you know? There are Solar drying, Vacuum drying, microwave drying, high-frequency drying and so on.

Fujian Zhangping CHIQIN Technology Co. Ltd, is professional in wood drying over 20 years, covering Aluminum Wood Drying Kiln, Heat Pump Wood Drying Kiln without heat source, Veneer Drying Equipment, Wood carbonization kiln,Food Drying Kiln, Kiln Components etc with high quality and reasonable price.

The company's independently developed integrated aluminum alloy food drying kiln is progressing smoothly, and the product has been produced and shipped.

When the wood dryer is running in the main hall, the fuel inside the machine will burn outside to produce heat energy. These energies will be fully absorbed through the transfer medium, and then the medium will evenly spread the absorbed temperature throughout the large material box of the dryer, forming a high temperature of about 180 degrees. Then, the air in the entire furnace box is circulated by the thermal circulation fan inside the equipment. The high temperature combined with air circulation can achieve a drying effect that everyone can imagine.

During the drying process of wood, it is necessary to conduct real-time monitoring of the temperature and humidity status of the drying medium in the drying room, changes in the actual moisture content of the wood, steam pressure inside the heater, and the operation of the electric motor, in order to execute the wood drying process conditions reasonably and ensure the quality and cycle of wood drying. The detection system mainly includes dry bulb temperature sensor, balanced moisture content sensor, wood moisture content sensor, as well as dry bulb temperature system display, balanced moisture content system display, and steam pressure gauge display. The most important thing is to ensure the accuracy of the dry bulb temperature and balanced moisture content detection device.

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.

A wood drying kiln is a device that uses hot air to dry wood. The drying principle is to heat the wood with hot air, causing the moisture molecules inside to evaporate, thereby achieving drying. The entire drying process is divided into three stages: preheating stage, normal temperature stage, and heating stage.

Wood can be carbonized by long-term pyrolysis treatment at high temperatures and pressures ranging from 180 ℃ to 250 ℃. The treatment of wood carbonization is a purely physical technique. In the process of wood carbonization, only temperature and water vapor are involved, and no chemical reagents or foreign objects are added. Therefore, carbonized wood is both environmentally friendly and safe, making it an environmentally friendly material.

The main elements of kiln drying wood drying equipments are described below: a) Construction materials: The wood drying kiln chambers are generally built of brick masonry, or hollow cement-concrete slabs. Sheet metal or prefabricated aluminium in a double-walled construction with sandwiched thermal insulation
