In drying Australian veneer it was found that roller and mesh belt mechanical dryers had too high an installed cost per unit output, while a counter-flow progressive kiln system, using vertical racking of the veneer, resulted in degrade from splitting and buckling. The latter difficulty was analyzed as resulting from uneven air flow in the kilns. A new dryer design was built and tested, and it was shown that the improved circulation control of this unit resulted in rapid drying schedules and greatly improved control of end frilling and splitting.
