What Is Seasoning of Timber?
Important Point
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.
1. Natural 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.

- 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.
Wood Seasoning
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.
What Is Seasoning of Timber?
The process of drying out the water from “wet” or “green” timber is termed “seasoning”, or more simply “drying”. Water is just as essential to the life of a tree as it is for all living matter.
What Is Seasoning?
Seasoning is the process of supplementing food via herbs, spices, salts, and/or sugar, intended to enhance a particular flavour.
Timber Seasoning
Timber seasoning, also known as wood seasoning or wood drying, is the process of reducing the moisture content of freshly cut or green timber. The purpose of timber seasoning is to make the wood more stable and suitable for various applications by reducing its moisture content to a desired level.

Types of Seasoning of Timber
There are many ways of seasoning or drying timber, but only two methods have been found satisfactory, principally for economic reasons. They are air drying and kiln drying. Air drying will be considered in detail in this publication, but kiln drying is a special- ized process.
Wood Seasoning Methods
There are two main ways of seasoning timber. the first is the natural method where the timber drys naturally by air. The second is kiln drying, where the wood is circulated and the temperature of the wood is controlled by a kiln.
Wood Seasoning Is Used to
Freshly cut or “green” wood contains a significant amount of moisture, which needs to be reduced for the wood to be usable. Seasoning helps to remove excess moisture from the wood, reducing its moisture content to an appropriate level for its intended use. This is important because high moisture content can lead to dimensional changes, warping, and cracking in the wood.
Why Should Timber Be Seasoned?
Timber seasoning is the process of reducing moisture content from timber. This can be achieved in a few different ways, with kiln and air seasoning being the most common. If left unseasoned, timber can quickly warp, twist, and break as too much moisture wreaks havoc on the cellular structure.
Why Seasoning of Timber Is Done?
Before wood is utilised, it is allowed to dry out under controlled conditions during a process called seasoning of timber. In addition to enhancing the strength of wood and preventing wood rot, seasoning of timber also prevents changes in the size and shape of the wooden objects it is used to make.
Why Seasoning of Timber Is Important?
