The Air-Kiln Drying Technology Research on Australian Eucalyptus regnans Board

Abstract:

This paper researched on Australian Eucalyptus regnans drying properties by 100°C Test Method, also researched 25mm-thick boards dried by air-kiln drying schedule. The result indicated that the species belongs to refractory wood when drying, with checks and collapse defects that develop easily. In order to improve the drying quality, we adopted the method of first air-drying the moisture content (MC) to four different ranges and then kiln-drying. The two phrase air-kiln drying schedule concluded that the drying cycle of 25mm-thick Eucalyptus regnans board from 76.34% to 13.11% MC was 33.5 days, and the drying quality of visible defect met the requirement for the first level of the Chinese national standards.
