The process of kiln drying.seasoning consists basically of introducing heat. This may be directly, using natural gas and/or electricity or indirectly, through steam-heated heat exchangers, although solar energy is also possible. In the process, deliberate control of temperature, relative humidity and air circulation is provided to give conditions at various stages (moisture contents or times) of drying the timber to achieve effective drying. For this purpose, the timber is stacked in chambers, called wood drying kilns, which are fitted with equipment for manipulation and control of the temperature and the relative humidity of the drying air and its circulation rate through the timber stack (Walker et al., 1993; Desch and Dinwoodie, 1996).
This form of seasoning/drying provides a means of overcoming the limitations imposed by erratic weather conditions. In kiln seasoning as in air drying, unsaturated air is used as the drying medium. Almost all commercial timbers of the world are dried in industrial kilns.

What is kiln seasoning?
Kiln seasoning is the most effective commercial process for drying wood. It accelerates the moisture-removal process through the use of external energy.
What is the two types of seasonings in wood?
The two types of seasonings in wood are air seasoning and kiln seasoning. Air seasoning involves drying wood naturally by stacking it in a way that allows air circulation, which can take several months. Kiln seasoning, on the other hand, uses controlled heat and humidity in a kiln to speed up the drying process, typically reducing the time to a few days or weeks. Both methods aim to reduce the moisture content in wood, enhancing its stability and durability for various applications.

What is wood seasoning?
Seasoning of timber is the drying of timbers moisture content to a level below 22% by several methods, including Air seasoning, kiln seasoning or a combined of both. Seasoning of timber allows wood to be used for practical purposes whether it be for shaping, constructional purposes, what ever the need for timber, it must be seasoned.
What is the advantage of kiln seasoning?
it can be done in a short time.
What are the two types of season?
The two types of seasoning are the natural/air seosoning and the kiln seasoning
2 types of moisture in the two stages of wood seasoning?
Wood seasoning involves two types of moisture: free moisture and bound moisture. Free moisture is the water that exists in the wood's cells and can be removed relatively easily during the initial drying phase. Bound moisture, on the other hand, is water that is chemically bound within the wood fibers and requires more intensive drying methods, such as kiln drying, to eliminate during the final seasoning stage. Properly seasoning wood reduces its moisture content, enhancing its stability and durability for various applications.
How does conversion and seasoning work with wood?
Seasoning of wood is removed of water and moisture in wood
What are the disadvantages of wood seasoning?
Wood seasoning or drying reduces the moisture content of wood. If the wood is dried to quickly it will shrink at the surface and compress the damp interior.
Is the wood in this product kiln-dried for optimal quality and performance?
Yes, the wood in this product is kiln-dried for the best quality and performance.
What is green wood?
Uncured or non-Kiln dried wood.
What are the three different stages of kiln seasoning?
Stage 1 - steam is ejected into wood at a low temperature to force moisture out. Stage 2 - steam is reduced and temperature is increased to dry the wood. Stage 3 - then there is a flow of hot almost dry air
