Introduction
Veneer drying is an important process before plywood manufacturing. Controlling veneer’s moisture content to Optimized value for each wood material is a key to make good adhesion characteristics at next plywood manufacturing process. For this purpose, humidity of the air in dryer is controlled and moisture content of veneer is adjusted.
Expected Benefits
- Increase Energy Efficiency of Veneer Dryer Process
- Reduce Operating Cost
- Improve Yield of Veneer for Plywood Manufacturing
- Improve Quality of Veneer for Plywood Manufacturing
Process Overview
In order to control veneer’s moisture content to optimized value from 6 to 20% for each wood material, humidity of the air in the dryer is measured and controlled from 30 to 40%. Temperature is controlled from 130 to 200 deg. C.
As the results, dry veneer with optimized moisture content is manufactured.
