Veneer Dryer Problems And Their Fixes

Veneer dryers are essential tools for processing and drying veneers for a variety of uses. They guarantee uniform drying, boost longevity, and improve quality. Like any equipment, they have potential problems that might arise when they are in use, despite their significance.

Let's discuss common problems that occur during the veneer drying process and how to resolve them.

The Veneer Side Has A Wavy Edge

Cause: The problem occurs when the veneer is not correctly positioned on the dryer's mesh belt, there is unequal tension during drying, the board is too thin and dries quickly, or there is an excessive width gap on both sides of the veneer peeling machine.

Solution: Enlarge the knives on both sides; increase the equipment's humidity levels; and reposition the exhaust fans or vents.

The Crack At The End Of The Veneer

Cause: Leaving wet veneers stacked for long periods of time and manually loading and unloading are the usual causes of this problem.

Solution: Proceed with prudence. For veneers that have been kept for a long period, moisten the ends before drying. Refrain from overexposure to dampness or heat. To avoid cracking, set the dryer to dry slowly and evenly.

Some Veneers Are Too Moist Or Dry

Cause: The cause of the issue is the uneven drying circumstances and the differences in the initial moisture levels of veneers.

Solution: Use of a moisture meter to track moisture levels before and after drying, as well as distinct drying procedures for veneers of various thicknesses and wood species. To avoid drying anything too much or too little, adjust the drying settings to a gradual, equal drying process.

The Moisture Content Of Each Part Of The Veneer Is Different

Reason: There are variations in the veneers' thickness, an uneven initial moisture level, and improper operation of the dryer.

Solution: Fix the dryer; gauge the moisture content of the veneer before it dries; adjust the disparity in veneer thickness.

Crack Or Break In The Middle Of The Veneer

Problem: The machine's temperature is too high, its humidity is too low, and it doesn't meet the required drying conditions. The dryer's feeding speed is improper.

Resolution: Reset the dryer parameters, change the feeding speed, and tweak the dryer's moisture system.

The veneer dryer will have an impact on the production of plywood in the future. Variations in humidity in various areas might cause issues with heat presses and glue machines. Dependable machinery reduces production costs, upholds the necessary standard of quality, and dries rapidly.
