wood kiln drying
A kiln is an enclosed structures designed for drying materials such as wood. With a kiln, you can control temperature, airflow, and humidity levels, resulting in better quality dried lumber. Using kiln rather than air drying can make the work a lot more easier and faster. So, most wood production mills use this oven to bring down the moisture content of the green lumber to the desired level. The purpose of this process is to keep the moisture at a level where it won’t cause further damage. Kiln-drying can help avoid damages such as warping and twisting of the logs that is dried during furniture operation. Unlike air-drying that is done in an open place, kiln-drying is done in a closed chamber. Everything in kiln-drying is in your control, in terms of the quantity and weight of the lumber to dry to, the temperature you want in order to dry them, and the time of drying that you prefer according to the appropriate time the wood needs.
Different Kind Of Wood Kilns
Solar
A solar kiln relies on solar to heat and dry the content inside. Then sunlight is absorbed by the collectors, which transfer the heat to the air. These wood kilns usually use electric-powered fans to enable the air to freely circulate through the wood. Solar drying is a very expensive process and you’ve got to run the fans a long time making the drying quite expensive.
Conventional
A conventional kiln has pipes that radiate heat into its chamber, which is forged from steam or by hot water coils. Then the wood is heated by burning its content of biomass. The moisture content of wood is converted into vapor, which then is released through the hot air. This demands a significant amount of energy for the wood to completely dry.
Dehumidification
Dehumidification kiln is advantageous because it generates a lot of environmental benefits. These kilns use a heat pump system that extracts moisture out of the wood as the evaporated water is condensed on the refrigeration coils. The generated condensation is drained as a cool liquid instead of being released as warm air.
Vacuum
Vacuum kilns are known for their high-drying speed systems. However, they are costlier than either conventional or dehumidification kilns since the heat of vaporization is being provided by electricity instead of local fossil fuel. Atmospheric pressure determines the boiling point of water.
Radio Frequency
Radio frequency wood kiln is used to dry the entire timber evenly, right down to its center. In this, the water molecules will excite, align and exit the wood through the natural veins water traveled while the tree was alive. Its system hold the wood in place during the gentle drying cycle to ensure straighter outcome
Microwave
Microwave dryer is normally applied for wood second process before we make any wood craft or wood furniture, microwave dryer could further dry off those wood to achieve the excellent drying result. This drying possess the disinfestation function to assure longer wood reserving time and prevent moldy

air drying disadvantage
In the case of air drying the logs are not only left depending of the weather and the climate fluctuations, but there are also other associated costs including costs of storage as the process generally takes a minimum of 12 months under optimum conditions, in order for the wood to be ready. In fact, air drying will never bring the humidity level down to the needed level of flooring applications. Also forget that the wood would be absolutely susceptible to bacteria and insects during that long period of storing.
Wood kiln advantage
Instead of waiting several months in air drying, your kiln dried wood can be ready within only a few weeks. In fact, advancements in wood drying technology have reduced the time it takes, lowered the risks of damaging your lumber, and reduced other costs. Kiln dried wood is your ultimate choice since the drying method is a great way of purging timbers of mold and insect infestation.
Goal of Wood kiln drying
The two primary goals of the kiln-drying process involve moving the moisture to the surface of the timber and letting it into the atmosphere. That’s where the trio of controlled airflow, temperature, and humidity comes in. While the airflow and relative humidity in the kiln helps with the evaporation of the moisture in the timber, increasing temperature speeds up diffusion, which helps to drive moisture to the surface.

Bottom FAQ
Kiln drying is a common procedure in wood production mills, and it is used to efficiently reduce green timber moisture levels to “workable” levels–moisture content levels that will not result in the variety of problems that can be created by over moisture levels in wood.
Modern high-temperature, high-air-velocity conventional kilns can typically dry 1-inch-thick (25 mm) green lumber in 10 hours down to a moisture content of 18%. However, 1-inch-thick green Red Oak requires about 28 days to dry down to a moisture content of 8%.
There are many reasons why wood suppliers like Northern Log Supply believe kiln-dried logs are better than air-dried logs. Because of the high heat, kiln drying ensures that all insects, eggs, mold, and fungi in the wood are killed and dries off the resin, which would otherwise turn to liquid at room temperature.
This incredibly low moisture content also makes kiln-dried wood great for cooking. Its hotter burns cook food more thoroughly than seasoned firewood. And its cleaner smoke produces better tasting food.
Kiln drying your own wood at home can be a great way to sustainably harvest the materials around you, and dry it fast enough to build furniture with. If furniture is made with wood that is too wet, it will continue to dry and crack, possibly ruining the piece.
Temperatures inside the kiln range from 120 to 190 degrees F, depending on the stage of drying. Although there are kilns in which temperatures reach up to 240 degrees F, they are usually limited to softwoods that dry very easily and low-value hardwoods.
Yes, because kiln dried wood goes through an important process, it really does make the best quality wood furniture. The biggest benefit of making furniture from kiln dried wood is that there is less moisture in the wood, which provides for stronger, better looking furniture.
