Do the veneers you dried have cracking problems?

Customers often report that the veneers dried by the dryers they used in the past have cracking problems. What is the reason for this phenomenon?

This is likely to involve the internal structure of the dryer and the stability of the dryer's operation.

If the foundation is not leveled during the early installation of the dryer, the dryer is unbalanced as a whole, which may cause the rollers to be not completely on a horizontal line, causing the veneer to run unsteadily in the dryer.

The board may have cracking problems.

In addition, the spacing between the rollers of the dryer, technically speaking, the roller spacing from the axis to the axis of the four-layer roller dryer is 330mm, and the upper and lower air ducts are laid between the front and rear rollers. If the roller spacing is too large, the veneer will run unsteadily inside the dryer, and the front edge of the veneer is easy to get stuck, which may also be one of the reasons for the veneer being dried out.

In addition, during the veneer drying process, the moisture at the edge of the veneer evaporates faster than the middle part, and the shrinkage and deformation of the edge part are restricted by the middle part, so the edge of the veneer is prone to ripples and sometimes cracking.
