Wood Production: Manufacturing & Kiln Drying

we turn trees into manufactured wood products. Throughout the process, the moisture content (MC) of the wood is an important factor for producer and end user alike.

OUR LUMBER MANUFACTURING PROCESS GENERALLY FOLLOWS THESE STEPS:

1. Head Rig: The primary saw cuts the tree into sawn pieces or boards.
2. Edging: Removes irregular edges and defects from sawn pieces or boards.
3. Trimming: The trimmer squares off the ends of lumber into uniform pieces.
4. Rough Lumber Sorting: Pieces are separated based on dimension and final product production, whether the finished piece will be unseasoned (known as “green”) or dry.
5. Stickering: Lumber destined for kiln drying production is stacked with spacers (known as stickers) that allow air to circulate within the stack (green product skips this stage and the next).
6. Drying: Kiln drying wood speeds up the natural evaporation of the wood’s MC in a controlled environment.
7. Planing: Smoothes the wood’s surfaces and ensures that each piece has a uniform width and thickness.
8. Grading: Assigns a “grade” to each piece of lumber that indicates its quality level, based on a variety of characteristics, including its MC

KILN DRYING WOOD FOR MAXIMUM VALUE AND USABILITY

In order to maximize wood’s value and strength, Our mills invest both time and money in the kiln drying processes to remove excess moisture from the lumber stack. In fact, kiln drying on some hardwood species can take up to (and beyond) a month, depending on the initial MC of the wood

AIR HUMIDIFICATION FOR THE TIMBER PROCESSING AND FURNITURE MANUFACTURING

Like all hygroscopic materials, the water content of wood varies depending on the relative humidity of the environment in which it is located.

During cold weather, the raw material is generally stored either outdoors, or in unheated rooms with high relative humidity. In processing areas, the relative humidity is usually lower.

The interior fibres of the wood react to this change when moving between areas and can crack, deform, or significantly change in size, all of which causes a deterioration in value and a problem with productivity throughout the industry.

Ideally, the wood should usually contain 11% moisture content, which requires a storage area with an RH of 60%. This can be hard to achieve as it is unusual for a ducted air conditioning facility to be installed in either processing or storage areas.
