Timber drying: top loading
Timber drying: top loading
Information
Top loading is an effective method to reduce the twisting of timber during drying. Top loading can be applied using weighted blocks, such as concrete, laid on top of the timber stacks loaded in the kiln, or using pneumatic or hydraulic pressure frames, that are pressed into the top layer during the drying process.
Pneumatic pressure frames require greater investment, but the benefit is that they can adjust the pressure during the drying process. Also, in contrast to concrete block loading, pneumatic pressure frames do not reduce the drying capacity.
