What Is Seasoning of Timber?
The wood spice process is the process by which the moisture in the wood is reduced to the required level.
By reducing the moisture content, strength, elasticity, and durability properties are developed. A well-seasoned wood contains 15% moisture content.
It is a process by which the amount of moisture in a freshly cut tree is reduced to a suitable level. Doing this increases the durability of the wood. The different methods of spice used can be classified into:

Type of Seasoning of Timber
- Natural seasoning.
- Artificial seasoning.
It can be air seasoning or water seasoning.
1.1. Air Seasoning
Air seasoning is done in the shed with a platform. As shown in below fig, wooden piles are stacked on platforms approximately 300 mm high.
Care is taken to see that there is proper air circulation around each wooden hair. Over a period, the moisture content decreases in a natural process. A well-seasoned wood contains only 15% moisture. It is slow but has a good seasoning process.
Water is sprayed on the banks of rivers. The thick end of the wood is placed, pointing upwards. After a period of 2 to 4 weeks, the wood is taken out.
During this period, the sap contained in the wood is largely washed away. The wood is then stalked in a shed with free air circulation.
1.2. Water Seasoning of Timber
Water seasoning is the process in which timber is immersed in water flow which helps to remove the sap present in the timber. It will take 2 to 4 weeks of time and after that, the timber is allowed to dry. Well-seasoning timber is ready to use.
2. Artificial Seasoning:
In this method, the wood is kept in a chamber with regulated heat, Controlled humidity and proper air circulation. Seasoning can only be completed in 4 to 5 days.

There Are Different Ways of Seasoning:
- Boiling Seasoning:
- Kiln Masala Seasoning:
- Chemical Seasoning:
- Electrical Seasoning:
2.1. Boiling Seasoning:
In this method, the wood is immersed in water, and then the water is boiled for 3 to 4 hours. It is then slowly dried. Hot steam can be circulated on wood instead of boiling water. process of
The spice is sharp but expensive.
2.2. Kiln Masala Seasoning:
The kiln is an airtight chamber. The seamed timber is placed inside it. Again fully saturated air with a temperature of 35 ° C to 38 ° C is forced into the kiln. Heat slowly
The kiln used may be stationary or progressive. Carts moving from one end of the wood kiln to the other end in the progressive kiln are gradually eliminated.
Hot air is supplied from the discharging end so that the temperature rise is gradual from the charging end to the discharging end. This method is extensively used to make spices.
2.3. Chemical Seasoning:
In this method, the wood is immersed in a suitable salt solution. The wood is then dried in the kiln. Initial treatment by chemical seasoning ensures uniform spicing of the outer and inner parts of the wood.
2.4. Electrical Seasoning:
In this method, a high-frequency alternating current is passed through the wood. The resistance to electric current is low when the moisture content in the wood is high.
Reduced moisture content reduces resistance. A measure of resistance may be used to prevent spice at the appropriate level. However, it is expensive to process. This technique has not been attempted in some plywood industries but on large scale wood spices.

Reason for Seasoning of Timber:
Wood seasoning is applied to meet some specific requirements. There is a reason for wood seasonings to follow.
- To change and improve the qualities of wood.
- To make a correct percentage of wood shrinkage.
- To ensure the use of forests.
- To reduce the adverse behavior of wood.
Improved Ability by Seasoning of Timber:
By seasoning, some commonly known properties are improved which are outlined below:
- Painting and finishing
- Resistance to insect attack
- Electrical Resistance
- Heat content
Benefit Seasoning of Timber
- Good quality of seasoned wood.
- A large amount is convenient in this process.
- Well experienced wood construction.
- It takes less time. Generally, 3-4 hours is quite good.
- Develops strength and elasticity.
Seasoning of Timber
Seasoning is the process of drying timber to remove the bound moisture contained in walls of the wood cells to produce seasoned timber. Seasoning can be achieved in a number of ways, but the aim is to remove water at a uniform rate through the piece to prevent damage to the wood during drying (seasoning degrade).
Artificial Seasoning of Timber
Artificial seasoning is the process by which lumber is dried using man-made devices such as a kiln. Regular wood seasoning is done by air drying in conditions below 18 percent moisture. There are multiple advantages to having wood artificially seasoned that relate to the quality, strength and cost of the wood.
Seasoning wood is the process of correctly drying timber in order to remove moisture in the cells of the wood walls. It is a necessary procedure to produce seasoned timber, helping it to burn cleanly. Seasoning can be achieved via several methods, but all methods aim to remove water and prevent damage to the wood.
Natural Seasoning of Timber
- Water seasoning is the process in which timber is immersed in water flow which helps to remove the sap present in the timber.
- In the process of air seasoning timber logs are arranged in layers in a shed. …
- In case of chemical seasoning, timber is stored in suitable salt solution for some time.
