Abstract

This study aimed to evaluate the spatial distribution of the air circulation speed and the final moisture content of pine lumber after kiln drying by using geostatistics. Two kilns acting on boards of 27 mm and 42 mm were evaluated. Air circulation speed and final moisture content were collected in different regions of the kilns. There was no significant difference for air circulation speed and final moisture content between the front and rear regions of the equipment. In the horizontal axis (Y-axis), air circulation speed averages did not differ statistically in both situations, but higher values for this variable were obtained from the spaces between the piles. Final moisture content tended to increase when closer to the door opening. In the vertical axis (Z-axis), the lower part tended to reach higher air circulation speed values. Thus, the spatial behavior influences the air circulation speed and final moisture content during lumber drying. Besides, the variograms presented the same tendency in comparison to the data obtained in a conventional manner, which indicates that geostatistics can be used to represent variables in kilns during the drying process.

松树木材干燥:用于干燥窑的地质统计学

本研究旨在利用地质统计学的方法对松材窑干后空气循环速度和最终含水率的空间分布进行评价。对两种作用于27mm和42mm板上的窑炉进行了评价。在窑内不同区域采集空气循环速度和最终含水率。设备前后区域的空气循环速度和最终含水率无显著差异。在水平轴(y轴)，两种情况下的空气循环速度平均值没有统计学差异，但该变量的较高值来自桩与桩之间的空间。最终含水率趋于增加，当接近门打开。在纵轴(z轴)上，下部趋向于达到较高的空气循环速度值。因此，空间特性影响木材干燥过程中的空气循环速度和最终含水率。此外，与常规方法获得的数据相比，变异函数呈现出相同的趋势，这表明地质统计学可以用来表示窑中干燥过程中的变量。
