How long does it take wood to dry

Wood drying is also seasoning lumber or wood seasoning, the purpose it to reduce the moisture content of wood before make furniture or other wood products. Before we talk the drying time, let’s talk about the three methods by which timber can be dried.

1.Air drying

Air drying is also nature drying. it is the traditional way to dry the timber. It is drying the timber by exposing it in a clean,cool,dry and shady yard.It is drying the timber by exposing it in a clean,cool,dry and shady yard.The technique of air drying consists mainly of making a stack of timber (with the layers of boards separated by stick) on raised foundations. The costs for storing wood is the only operate cost, The exactly drying time based on the wood species,thickness and climate.Typical from several months to years for green timber to air dried timber. With the development of productivity,cash-flow is getting and more and more important for wood industry. So it is gradually unable to meet the production demand.

2.Conventional kiln

The timber is stacked in chambers, which are equipped with fans, boilers to control the temperature,relative humidity and circulation rate. That is conventional kiln drying. It is using coal,electricity, firewood to get steam. through steam heated exchanges deliberate control of temperature, relative humidity and air circulation creates variable conditions to achieve specific drying profiles. Actually it’s same principle with air drying. Just artificially created a wood drying environment, thus shorten the drying time. Normally the drying time is couple weeks to month to get quality kiln dried wood. The kiln need experienced operators and for thick blocks it is difficult to solve surface is dried but core still wet problem.

3.High frequency vacuum wood dryer machine

High frequency vacuum drying is the advanced wood drying technology. It is using electricity filed principle to make water molecule friction get heat. it is kind of directly heating. That will ensure wood inside and outside heating uniform.At a vacuum water boils at a lower temperature. In addition to speed a vacuum kiln can also produce an improved quality in the wood. That machine is the fastest way and most efficient with energy usage to get quality dried wood.With the development of technology, the performance of high-frequency drying equipment has been very perfect, especially for the drying of hard precious wood For this 500mm thickness blocks it can finish the drying process within 25 days. It solved the cash flow problem in wood industry.
