Effect of water spray storage of southern pine logs on the drying and shrinkage of lumber

Ten charges of southern yellow pine were dried to evaluate the difference in drying of lumber from freshly cut and water-stored logs. Final moisture content and shrinkage were evaluated. Kiln temperatures were held the same for all charges: 250?F dry bulb, 180?F wet bulb. Results indicated that the difference in drying times between the two wood sources was of little practical significance. These results show that it is not necessary to segregate lumber from water-stored material at the dry kiln; kiln charges can be mixed. Additionally, shrinkage values between the two wood sources were not significantly different. This indicates that there is no need to increase green target size in the sawmill when sawing water-stored material.
