Conventional drying kilns are generally composed of kiln body, kiln door (lifting door device), heating system, humidity control system, air circulation system, intake and exhaust system, detection system and control system.

After more than 20 days of efforts, the Indonesian customer installed two wood drying kilns by himself according to the drawings, videos and remote installation instructions provided by our company

Wood carbonization, also known as wood high-temperature heat treatment (Thermal Modification), is an environmentally friendly wood that uses water vapor, inert gas, oil, water, etc. as heat-conducting media to perform short-term pyrolysis treatment on wood at a temperature of 160-250 °C. Physical Protection Technology.

Wood drying is the process of heating the wood under the condition of controlling the medium temperature and relative humidity, so that the internal moisture of the wood moves to the surface, the surface moisture evaporates to the outside, and the process of gradually removing moisture from the wood. In order to achieve effective drying quality, it is necessary to control the temperature and humidity of the drying medium, and adopt a reasonable drying process and operation method. The more common method used at present is the method of convection drying.So what are the benefits of drying wood? There are mainly the following aspects:

Carbonized wood is a modified product of high-temperature heat treatment of wood. Compared with ordinary wood, it has a series of characteristics:

Classification According to the performance and application of the product, carbonized wood can be divided into two categories: indoor use and outdoor use. In addition to the requirements for appearance quality, the former mainly requires dimensional stability. The tangential swelling and drying shrinkage of the wood is required to be 6-8%, and its corrosion resistance level is required to be grade Ⅲ—slight corrosion resistance; the latter, in addition to In addition to the requirements for appearance quality, the main performance requirement is biological corrosion resistance, and its corrosion resistance level is required to be level II—corrosion resistance. In addition, the chordwise swelling and drying shrinkage of wood are required to be 5-6%.

The industrial production of "carbonized wood" originated in Europe in the 1990s. Its typical production processes include: Thermal-wood, Retification, PLATO-process and oil-Treatment, etc. Carbonized wood production equipment at home and abroad can be divided into two categories: kiln type and tank type. Each has its own characteristics, but it has common requirements, and its process also has common characteristics.

When wood is carbonized, if the process or operation is improper, many defects will occur, mainly including cracking, deformation, uneven color, knot falling off, and even fire. However, if the causes of these defects are mastered, basically these defects can be prevented.

Wood drying rooms are generally classified according to the following main features.

The brick-concrete structure of the traditional drying room shell is low in cost and easy to build. However, there are some problems in the use of brick-concrete structure shells, such as poor corrosion resistance and cracking of the shell. In particular, the cracking of the shell not only increases the heat loss of the drying chamber, reduces the airtightness, and accelerates the destruction of the shell due to the intrusion of corrosive gases, but also seriously affects the normal use of the drying chamber. Therefore, precautions must be taken in the design and construction of the shell.
