Excerpt: Wood drying (also seasoning lumber or wood seasoning) refers to reducing the moisture content of wood prior to its use. There are two main reasons for drying wood: For some purposes wood is not dried at all (it is used "green"). Often the wood needs to be in an equilibrium with the air outside (e.g. Purchase includes free access to book updates online and a free trial membership in the publisher's book club where you can select from more than a million books without charge. Excerpt: Wood drying (also seasoning lumber or wood seasoning) refers to reducing the moisture content of wood prior to its use. There are two main reasons for drying wood: For some purposes wood is not dried at all (it is used "green"). Often the wood needs to be in an equilibrium with the air outside (e.g. construction wood) or the air indoors (e.g. for furniture). Wood is either air-dried or kiln-dried. Usually the wood is sawn prior to the drying process, but not always (i.e. drying the whole log) Wood is divided, according to its botanical origin, into two kinds: Softwoods from coniferous trees and hardwoods from broadleaved trees. Structurally softwoods are generally simple in structure and lighter whereas hardwoods are generally complex in structure and harder. However, in Australia softwoods generally refer to rainforest trees and hardwoods refer to sclerophyllous species namely Eucalyptus spp. Softwood (like pine wood) is much lighter and easier to process than the heavy hardwood (like fruit tree wood). The density of softwoods ranges between 350-700 kg/m³, while hardwoods are 450-1250 kg/m³. Both consist of approximately 12 % moisture (Desch and Dinwoodie, 1996). Due to the more dense and complex structure of hardwood, the permeability is very low in comparison to softwood, thus making it more difficult to dry. Even though there are about hundred times more species of hardwood trees than softwood trees, the ability to process and dry softwood faster and more easily makes it the main supply of commercial wood today. The timber of living trees and freshly felled logs contains a large amount of water, which often constitutes over 50% of the woods actual weight. Water has a significant influence on wood: wood continually exchanges moisture (wat. Books, , Timber-Seasoning~~Books-LLC, , , , , , , , , , General Books LLC<
