Wood drying ways

Why you need to dry wood for woodworking ?

When wood is used as a construction material, whether as a structural support in a building or in woodworking objects, it will absorb or desorb moisture until it is in equilibrium with its surroundings. Equilibration (usually drying) causes unequal shrinkage in the wood, and can cause damage to the wood if equilibration occurs too rapidly. The equilibration must be controlled to prevent damage to the wood.

Different ways for wood drying 

You might do not  know which drying way is the much suitable for your wood, let’s see what’s the difference between them

Drying way Traditional steam drying hot wind drying platen vacuum drying microwave drying common high frequency drying high frequency vacuum drying
Drying speed Slow Slow slight faster fast fast fast
Working range Wood thickness 10-55mm,mid-hard wood drying Wood thickness 10-55mm,mid-hard wood drying thinner timer drying is stuitable for panel of floor thickness is less 20mm it is suitable to dry veneer, thinner timber,hard wood or thicker timber(especially for red wood) in final drying and secondary drying
Loading way Separated bar for ventilation between wood Separated bar for ventilation between wood more cumbersome loading simple loading but it has request for loading position, or the wood will be dried uniformly very simple, directly stack timber on feed device, no need battle
Flatness after drying bad,easily deformed bad,easily deformed good, good flatness by hot platen better best,the timber will not happen deformation and bend under the hydralic platen press timber tightly
Wood stress after drying little much little less least
Drying cost Low cost , but high cost for thicker and hard wood Low cost , but high cost for thicker and hard wood higher higest higher, but low cost for hard wood, thicker wood and secondly drying for wood
Uniform moisture content after drying bad,easy deformation worse than traditional steam drying good  normal bad better
Operation Complicated, and need professional training Complicated, and need professional training Complicated, and need professional training easy easy easy
