FIELD: arrangements for supplying or controlling air or gases for drying solid materials or objects, particularly to dry lumber for wooden article, namely furniture and parquet production. ^ SUBSTANCE: method involves performing automated temperature and humidity of drying agent in drying chamber; controlling humidity of stacked lumber; preliminarily measuring initial lumber humidity and thickness; performing multi-objective optimization of temperature and humidity of drying agent at each of three stages on the base of predetermined initial lumber humidity and thickness; working out control action on drying process, which provides minimal value of three optimality criteria, namely y1 - lumber cracking criterion, y2 - lumber deformation criterion and y3 - total lumber drying time criterion. ^ EFFECT: increased efficiency of lumber drying operation, decreased lumber cracking and deformation during drying operation and reduced drying time. ^ 1 dwg |
