In hardwood kilns, the conventional wisdom requires that multiple samples which are removed from the wood drying kiln for periodic moisture measurements, be repositioned within the lumber charge in a horizontal orientation, that is parallel to the air stream through the charge. As will be explained in the following, the present invention represents a substantial diversion from conventional thinking and results in a highly accurate measurement apparatus and technique for controlling hardwood kilns

Four Indonesian customers come to visit our factory.They visited our drying kiln and workshop to learn more about product information, and discussed their plans and future procurement plans in the conference room

A wood drying kiln and airflow controlling process is described in which the kiln includes an structure with a charge receiving chamber, and a door accessible opening to allow passage of a charge of lumber for drying. Circulating fans in the structure produce airflow that is directed by baffles in a prescribed path through the charge. At least one row of elongated resilient brush bristles within the structure are positioned therein to yieldably engage the charge of lumber placed within the charge receiving chamber.

Wood drying kiln can drying different type of wood,then there has a question is that how do i choose the best kiln dried wood?

Three main external factors which affect the speed of wood drying equipment.

The 21st century is in a shortage of resources, will need much energy-saving and environmental protection, especially our timber resources are becoming increasingly scarce, but China’s timber resource utilization is not high. The waste of timber, mostly due to the wet unseasoned wood, or mishandled, resulting in falling timber, etc. even lost value. Fresh wood contains a lot of water, constantly evaporating water branch in a particular environment. Natural evaporation of moisture will cause the wood will shrink, cracking, bending, mildew and other defects seriously affect the quality of wood products, so the timber is made of various types of wood before the wood drying equipment must be used to force the timber (by control) drying.

Deep carbonized anticorrosive wood is widely used in wallboard, outdoor floor, kitchen decoration, mulberry house decoration, furniture and many other aspects. However, it is not recommended for use in contact with water and soil.

Wood carbonization mainly acts on hemicellulose, cellulose amorphous regions and hydrogen bonds connecting cellulose and hemicellulose.

Factors Affecting Wood Drying Speed The main factors affecting the drying speed of wood are medium temperature, humidity, air circulation speed, wood moisture content gradient, and temperature gradient.

Moisture in wood can move inside the wood under certain conditions, which is called moisture conductivity of wood. Moisture can drain from both ends of the wood by moving along the fiber direction, or it can drain from the sides of the wood across the fiber direction, and in most boards, the length is much greater than the thickness width. The side area of ​​the sheet is much larger than the end area. Therefore, although the conduction of moisture along the fibers is easier than that across the fibers, it is the conduction across the fibers that plays a decisive role in wood drying.
