Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln , the product is known as kiln-dried timber or lumber , whereas air drying is the more traditional method.
A moisture meter gives a reading of the approximate moisture content of wood. The reading helps in determining whether the wood is suitably dry for its intended purpose. The moisture content reading can also assist in planning a project design that will accommodate future changes in dimension caused by changes in relative humidity.
A process for steam straightening and kiln drying lumber, (1972). [10] A method for producing parallel laminated pine lumber from veneer, (1975). [11] A helical flaking head with multiple cutting circle diameters for milling lumber, (1977). [12] A system for burning green bark to produce heat or power in sawmills, (1977). [13]
The true costs of the drying system can only be determined when comparing the total plant costs and risks with and without drying. [citation needed] Kiln dried firewood was pioneered during the 1980s, and was later adopted extensively in Europe due to the economic and practical benefits of selling wood with a lower moisture content (with ...
However, in the 1980s, the development of chemical treatment processes allowed the wood to be more widely used for furniture making and frames. Rubberwood is generally treated soon after sawing by pressurized immersion in boron preservative solution to diffuse the chemicals. Then, the treated timber is kiln-dried to reduce its moisture content ...
The moisture in wood can be measured by several different moisture meters. Drying produces a decided increase in the strength of wood, particularly in small specimens. An extreme example is the case of a completely dry spruce block 5 cm in section, which will sustain a permanent load four times as great as a green (undried) block of the same ...
