The results show that a longer equalizing phase promotes better uniformity of moisture content. This improvement helps reduce certain drying defects, such as warping, and improves lumber grade.
Analyses indicate that incorporating and optimizing the equalizing phase can increase the value of the lumber.
The tests also allowed for the observation of the impact of conditioning and certain parameters, such as the wet-bulb depression in the central zone, on productivity.
In a context where it’s possible that some mills have excess drying capacity, this research suggests an adjustment of residence times and drying parameters to improve overall drying performance and the value of the products.
