Teal-Jones Lumber Meets the Challenge
When Teal-Jones Lumber, a member of the Teal-Jones Group, purchased Langdale Lumber in Antlers, Okla., in late 2014, it carried on its parent company’s tradition of providing customers with top-quality wood products.
The Oklahoma mill manufactures dimensional Southern Yellow Pine lumber, which is used in a wide range of building applications because of its strength, dependability, and versatility. Pine logs come to the mill from the surrounding area. At the mill, they’re cut, dried, and planed, and the lumber is sold to wholesalers throughout the United States and parts of Mexico.
On average, Teal-Jones produces 50 million board feet a year. In 2016, when this article was written, the mill was expecting record production.
The process for producing quality products and ensuring consistent grading standards is rigorous at Teal-Jones Lumber. Each piece is inspected and graded for knots, bark remnants, slope of grain, and material efficiency to meet or exceed all standards.
Moisture Management Is Critical
It’s in the mill’s two double-track kilns, each capable of drying 125,000 board feet per charge, that consistent quality is maintained.
“To help minimize warping and shrinkage associated with green lumber, our Southern Pine is kiln dried for long-term stability,” says Kerry Cogburn, Teal-Jones Kiln Supervisor.
“In fact, our kiln drying is critical to our success. In order to produce high quality products, it’s extremely important that we know the moisture content (MC) throughout the drying process because if we overdry or underdry the wood, we can downgrade it,” he adds.
To dry the lumber properly, Teal-Jones uses the MC4000 In-Kiln Moisture Measurement System from Wagner Meters. Installed in the mill’s two kilns, the MC4000 works in tandem with American Wood Dryers’ Drystar Computer Control System. The Drystar takes the information from the MC4000 and tells the kilns what to do: heat up or cool down, adjust the dry bulb or wet bulb, and open the vents.
As a kiln supervisor, Cogburn says kiln drying is an art that requires skill and technical knowledge. “But having a dependable in-kiln moisture measurement system working together with the Drystar computer system makes it that much easier,” he says.
There’s also a significant economic advantage.
“By having the in-kiln system, we don’t have to shut the kiln down several times, open it up, and lose all that heat. We rely on the Wagner system to tell us when our 2x products reach our target range of 19% MC and our 4x products hit 24% MC. It’s very costly to bring the kilns back up to 200°F or so.”
“By minimizing our hot checks to one, maybe two per charge, we’re not losing that heat. And that saves us energy. In fact, I estimate it saves us conservatively $300,000 annually due to savings in time, energy costs, and the effort that’s spent drying the wood,” he adds.
Meeting the Challenge
When the MC4000 says the wood is done, kiln operators confirm it with Wagner’s L722 Lumber Stack Probe attached to the L622 digital recording moisture meter. The challenge is leaving the right amount of moisture in the wood so it isn’t overdried or underdried.
“That’s where the L622 and the stack probe comes in handy. When the magical number (MC) comes up with the MC4000, they’ve been consistently reliable in confirming our wood is ready,” Cogburn says.
In the past, the mill used a pin meter to see if the charge was ready, but that proved unreliable and costly.
“With the pin meter we might have to start that charge two or three times before it was satisfactory. The L622 and the stack probe eliminate that,” he says.
“Plus, the L622 also does something else the pin meter couldn’t do. It allows us to download an informative report summary to a computer which we can print out. It’ll give me an average of the recorded moisture readings, graphs, and the overall MC of each charge. So it’s been a real valuable tool for us.”
Moisture management is critical for Teal-Jones Lumber, especially during kiln drying. “It’s what has helped us produce quality lumber consistently and efficiently,” says Cogburn.
“And, just as important, profitably, too.”
The Teal-Jones Group describes itself as the largest privately held forest products company operating on the West Coast of Canada.
Product Update: The L622 moisture meter mentioned in this article is no longer available. It has been replaced by the L5300 Industrial Hand-held Wood Moisture Meter, which works with the L722 Lumber Stack Probe.
