Abstract
Wood drying does not only consist in removing its moisture: the quality of the dried product is the main requirement for the industrial process. Because wood shrinks during drying, deformations and stresses develops than can lead to unusable product. When developing drying technologies and methods, the aim is to achieve the shortest possible drying times. The most common defects in wood after drying include cross warping (cup), which significantly affects the efficiency of processing the raw material into products. The research was focused on the effect of different drying conditions (temperature, drying gradient) on the size of the cross warping. Despite very intensive drying and large moisture gradients at the end of drying, the values of cross-peeling in beech samples after high temperature drying were small and the positive effect of high temperatures on the amount of drying of the wood was confirmed. A reduction in the size of the cross warping can also be achieved by effective loading of the samples in combination with a more precise control of the high temperature drying process so that smaller values of the moisture gradients of the samples at the end of the drying process are achieved.
