The methodology of acquisition and statistical analysis of data from the process of drying thin wooden elements
This paper presents an original methodology of acquisition and statistical analysis of data from the process of drying thin wooden items, without interference in the manufacturing schedule or process. The research was aimed at reducing the duration of the lamella drying process in a convectional drying chamber, and minimising non-conformities of dry lamellas. The authors discuss the effective application of convectional drying methods, taking into consideration non-homogeneous wood quality resulting from overor under-drying caused by uneven or insufficient exposure to the drying agent, long duration of the drying process serving to minimise the internal stress of the material, poor efficiency of the drying process, and relatively high operational costs. Based on the tests performed, a quick drying programme is recommended. To reduce the fraction of non-conforming lamellas, the authors suggest that the arrangement of lamellas in the cage be changed so that all lamellas are protected against unconstrained deformation.
期刊介绍:
Wood. Research papers. Reports. Announcements" ("Drewno") is an international scientific journal that publishes original results of innovatory basic and applied research concerning technological, technical, economic and ecological issues important for the wood science and forest-based industries, including their environment, and interesting to the international recipients. "Drewno" is an Open Access biannual journal.
Aims and scope:
wood science: anatomy, biology, chemistry, physics
wood mechanical and chemical technology, inter alia, sawmilling, composite wood products, wooden construction, furniture making, wood pulp, paper making
material engineering, biocomposites, nanocomposites
material management
environmental protection, safety of the processes, products and working stations
biotechnology
bioenergy, biofuels
forestry: harvesting and wood quality
wood-based industries economics
The Editorial Board of the journal especially welcomes articles concerning increase in wood resources (wood mobilisation); innovative composites and lignocellulosic materials; new trends in the protection, modification and finishing of wood; biorefining of raw wood material; "green" building; new technologies of wood waste recycling; sustainable development; innovation management; and business networks.
