| Summary: | The paper shows results of analysis of influences of oscillating parameters
of drying on measuring wood moisture content in the kiln, rate and quality of
drying. For this analysis, we used a conventional drying cycle, a cycle with
oscillating equilibrium moisture content (EMC), and a cycle with oscillating
temperatures. A special software tool was created for managing the
oscillations. It was shown that oscillations of EMC and temperatures result
in cyclic changes in wood MC, but also in the additional inaccuracies of MC
measurements in the kiln. The drying process of the cycle with oscillating
EMC lasted somewhat shorter than the other two cycles. Drying quality was the
same or better in the cycles with oscillations as compared to the
conventionally dried cycle, and the smaller tensions in the wood confirmed
the activation of the additional mechano-sorptive effect during cyclic
changes of MC in surface layers. [Projekat Ministarstva nauke Republike
