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|
