Title: High-temperature kilning of southern pine poles, timbers, lumber, and thick veneer

Author: Koch, Peter;

Date: 1973

Source: In: Proceedings, American Wood-Preserver's Association, Vol. 69: 123-140

Publication Series: Miscellaneous Publication

Description: At dry-bulb temperatures above the boiling point of water, with large wet-bulb depressions and high air velocities, southern pine prodcuts can be dried quickly. In an impingement-jet kiln at 300o F., veneer 3/8-inch to 5/8-inch thick can be brought to 10 percent moisture content in 40 to 75 minutes. Drying times for lumber arte linearly related to thickness, e.g., at dry- and wet-bulb temperatures of 240o and 160o F., time required is 10.4, 15.8 and 20.7 hours for thickness of 1.0, 1.5, and 1.9 inches. Under similiar conditions, planks or timbers 2, 3, and 4 inches thick can be dried to 10 percent moisture content in 22.4, 35.6, and 45.3 hours; surface checks in timbers so dried are absent or minor, but in 3- and 4-inch pieces end-checking may be moderate to severe. at 225o F., with 50o wet-bulb depression, poles 8 to 10 inches in diameter can be reduced to 30 percent moisture in about 44 hours.
