Lumber and other wood products usually contain considerable moisture after their production, and drying is essential to prepare them for further use. Proper drying reduces the magnitude of dimensional changes due to shrinkage and swelling, protects wood from microorganisms, reduces weight and transportation costs, better prepares wood for most finishing and preservation methods, and increases its strength. Drying is accomplished in yards in the open air or in closed kilns. Other methods of drying also exist. The object of open-air drying is to reduce the moisture content of wood to the lowest value permitted by weather conditions in the shortest ...(100 of 12879 words)
