Aim of the course and learning outcomes:
This learning concerned with wood drying processes. Lumber drying is one of the most time- and energy consuming steps in processing wood products. Educate in application special methods timber drying, know design and construction drying chambers, multiple source of heat in addition, the sensitivity of the structure to stresses set up in drying limits the drying rate; rapid drying causes defects such as surface and internal checks, collapse, splits, and warp. Graduate this learning can by used standard technical terminology.
