Modernization of drying chambers based on fuzzy regulation

One of the most important stages of woodworking is drying, thanks to which the physical and mechanical properties of wood are improved and its shelf life is increased. Drying of wood is a process that significantly affects the external environment. The fact is that drying most often takes place in convection drying chambers, which consume a lot of energy and are not efficient enough due to constant air exchange with the atmosphere. At the same time, about 50 % of the heat energy received is lost, and carbon dioxide released from the chamber negatively affects the environment. The paper proposes the modernization of a typical drying chamber to increase its efficiency by replacing the classical PID control with fuzzy logic algorithms in order to reduce the duration of transient processes.
