With this process, you allow your wood to sit passively at any given temperature and let it dry naturally. The pre-dryer looks like a large barn in a commercial operation but can be sized to fit the small producer. It is equipped with steam heat, several fans, and vents to maintain ideal air drying conditions year-round. Automatic controls monitor dry bulb and wet bulb temperatures. These controls open roof vents to exhaust humid air and side wall vents to admit fresh air.
I usually stack some fresh cut wood on my rack to add humidity to the house. Here is a photo from December 30 and a photo from yesterday. The wood has settled 3″. I did remove two pieces and have not checked for moisture content. I’ll suggest splitting the wet stuff down a little smaller.
Set each piece of wood on the rack so that no pieces are touching. For drying firewood, they can be stacked so that minimal touching occurs and maximum air circulation is achieved. If your wood is slightly too large and you are drying it for burning purposes, use a firewood splitter or a timber splitting axe to portion the logs into smaller sizes. Setting the lignin like this can have drawbacks if done too quickly however. When the wood dries the outer layers dry faster than the inner layers. If the outer layer “sets” up too fast it creates a hard shell around the inner layers and traps the moisture inside.
Once some cells lose most of the free water, a continuous pathway of water is no longer present and moisture cannot move as a liquid. Many people might not know this, but wood can’t go straight from the tree to a smoker. Such http://www.admobilya.com.tr/chip-carving-from-slojd-in-wood/ wood is what’s commonly referred to as green wood in the smoking circles. Whether you call it wood drying, wood seasoning or seasoning lumber, the point is you need to prep your wood before chucking it into the smoker.
Conventional Wood Drying
Hot, dry conditions of July and August may cause freshly sawn lumber from refractory species to dry too fast. The outer shell of oak and hickory boards may dry and shrink faster than the inner core, causing excessive checks and casehardening. Yellow-poplar and soft maple are less likely to be damaged by rapid drying. Other species are intermediate in their drying characteristics. End coating the boards of species that easily check and split with a wax-based solution, which can be applied by brush or spray, can help minimize degrade.
How To Dry Lumber
That moisture is naturally not replaced as it would be in a living tree, and the wood’s moisture level will drop considerably as it dries. Kiln drying significantly reduces the moisture content of green lumber, but there’s more to be considered. Compact, entry-level dehumidification kiln for drying lumber between 300 and 1,000 board feet.
The reality of wood’s nature, and indeed, part of its attraction over the centuries, is that it is a hygroscopic material. Until it is fully sealed, wood constantly interacts with moisture in its environment and will absorb or release moisture as necessary to find a balance with its environment. Mills and manufacturers alike invest time, money and training into their drying processes to provide optimal grade products at the correct moisture levels for their customers.
