American Wood DryersAmerican Wood Dryers

American Wood Dryers has been producing quality, efficient dry kilns for the lumber industry for over 30 years with installations throughout the world.

The company has supplied everything from package kilns for smaller volumes of hardwoods to large volume, high throughput conifer kilns, such as high temperature batch track or continuous track kilns.

Kiln structures are aluminum or steel. Enclosures are Alclad aluminum or type 304 stainless steel for some hardwoods. American’s prefabricated panel system reduces installation time and maintenance costs. Continuous kilns use a combination of steel and aluminum to optimize performance and cost.

Heat systems include hot water, steam, hot oil, and natural gas or biomass direct fired. Fan systems are either direct drive kiln duty motors or standard motors mounted outside of the kiln chamber. Variable frequency drives can be supplied to reduce electrical cost and optimize drying schedules.

Drystar PC-based proprietary control systems or PLC systems are supplied to customer preference.

USNRUSNR

USNR has manufactured track and package kilns for over 100 years. USNR says it has installed the largest number of continuous dry kilns in North America, and it continues to improve the design of its counter-flow kiln and related systems, including the 8-grate burner.

The 8-grate burner is the largest green fuel burner in the industry, capable of producing 40 mm BTUs, says the company. This powerful system offers the widest variety of heat sources including steam, shavings, green fuel, and natural gas. It can also be manufactured as a hybrid burner that uses a combination of different sources in the same system. This flexibility allows mills to use the fuel that gives them the best savings.

A new hybrid burner project in the U.S. South will provide natural gas and green fuel options. The ability to switch between different heat sources lets mills take advantage of price fluctuations and other market conditions.

Hildebrand-BrunnerHildebrand-Brunner

Hildebrand-Brunner recently introduced a new highly efficient continuous-type kiln, the Alexander Hildebrand Continuous Kiln (HCK-A).

This type of continuous kiln is designed for mills that produce large volumes of lumber product, e.g., dimension SPF. While designing its Alexander Hildebrand Continuous Kiln, the company put great emphasis on creating exactly the right drying conditions (temperature, climate, air speed) for the respective lumber moisture content. The technical features of each individual drying zone are customized to the drying state and moisture of the lumber passing through.

Lumber is placed length-wise on carts and dried during transport through a number of zones with separate climates. Ultimately, customers will dry lumber in the company’s continuous kiln HCK-A just as they would in a conventional package kiln. Conditions are perfectly adjusted to the lumber moisture content at all times.

It features the company’s new “greenkiln” technology for energy management and the Hildebrand Turbo Technology (HTT) ensuring tight final moisture distribution for maximum planer yield.

Logging and Sawmilling Journal
November 2017

On the Cover:
While others shy away from oilpatch logging, Alberta's JD Haggart Contracting pursues this business for one simple reason—it pays better and they have the experience to be able to mobilize quickly when an opportunity comes their way. They also have the equipment to deliver the wood, including two John Deere 2154 processor carriers, both equipped with Waratah heads. Read all about the operation beginning on page 10 of this issue. (Cover photo by Tony Kryzanowski)

Balancing out the forestry workplace
There’s a movement underway to encourage more women to work in the forest industry, and it’s getting some solid traction from forest company Tolko Industries—and full support from women who are now working in the industry.

Ability and availability = logging success
Alberta logging contractor JD Haggart—managed by the husband and wife team of Dave and Roxanne Haggart—know that ability and availability are keys to logging success, especially in oilpatch logging.

Front end focus following mill fire
Saskatchewan’s NorSask Forest Products is bouncing back from a fire that hit its sawmill earlier this year, and has invested $21 million on a major front end redesign following the fire.

Bringing on the next generation...
Nova Scotia’s Sebastien Pouliot knew he wanted to be a logger at a very young age—and he’s now successfully ushering in a new generation of equipment operators, through a training program.

Salvage logging in B.C.—but this time it's for burned wood
Forest companies and logging contractors are getting ready to go into salvage mode big-time to tackle the burned timber from the worst fire season B.C. has ever seen. It’s been estimated that about 53 million cubic metres of timber has been burned, about four times the provincial allowable annual cut.

Sawmill/speedway combo
Paul Hargrave and his son, Scott, have a passion for sawmilling—and for race cars, too, since they have a combination sawmill/speedway operation on B.C.’s Vancouver Island.

Team logging effort
The husband and wife team that manages Ontario’s St. Onge logging has been successful in directing their operations through the industry’s rocky times—and now has a very successful chipping operation, and recently started logging for EACOM and Weyerhaeuser.

The Edge
Included in this edition of The Edge, Canada’s leading publication on research in the forest industry, are stories from the Canadian Wood Fibre Centre, Alberta Innovates and Alberta Agriculture.

The Last Word
Jim Stirling on B.C.’s wildest wildfire season, and looking at how to prevent a repeat performance.
