| Summary: | The subject of this paper is the analysis of the influence of higher initial
temperatures during the drying of oak lamellas on the final quality and wood
colour. Two different drying schedules (initial temperature: 45°C and 50°C;
final temperature: 55°C) were used and then the drying quality and wood
colour were determined. The colour change was expressed by parameter ΔE but
also by the corrected parameter ΔE00. It was shown that the drying quality
was very high in both cases, and that the colour change that occurred during
drying was invisible to the naked eye. The application of higher
temperatures does not pose a risk to the drying quality due to the small
thickness of the wood and the short drying process. In industry, a higher
initial temperature is justified in situations where sufficient quantities
of (cheap) thermal energy are available. The results confirmed that the
percentage of lamellas’ deformation was reduced when the load was applied
while drying. |
