$a Cross warping during various drying processes of beech wood (Fagus sylvatica L.) $f Ivan Klement, Tatiana Vilkovská, Peter Vilkovský 215 $c Graf., obr., tab. 320 $a Lit. 330 $a Wood drying does not only consist of removing moisture; the quality of the dried product is the main requirement for the industrial process. Because wood shrinks during drying, deformations and stresses develop, leading to unusable products. When developing drying technologies and methods, the aim is to achieve the shortest possible drying time. 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 impact of different drying conditions (temperature, drying gradient) on the size of the cross warping. The lower values were for the low-temperature drying at 1.4 %. The high- temperature drying process increased values to double from 2.3 to 2.8%. A reduction in the size of the cross warping defects can also be achieved by effectively loading the samples in combination with 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. 463 -1
