ValutecValutec

Valutec is one of the world’s leading suppliers of timber kilns with more than 4,000 delivered kilns throughout its history. A strong focus on research and development has resulted in more than 20 international patents in technical solutions and guiding principles for drying and control systems.

In recent years, Valutec says that its TC continuous kilns have changed the way sawmills operate with a never-seen-before combination of flexibility, capacity and quality. In a TC kiln, the timber is dried during transport through a number of zones with separate climates.

In November, Valutec will start up its first TC kiln in North America at Pleasant River Lumber in Maine.

“We visited several Swedish sawmills that were using Valutec products and they exceeded our highest expectations in terms of the details, quality of design and energy efficiency,” says Jason Brochu, owner of Pleasant River Lumber. “At the end of the day, it was a very easy decision. Valutec has a product that will position us at the leading edge throughout North America when it comes to drying technology.”

USNRUSNR

USNR says its Counter Flow Kilns are the largest and most flexible in the industry. They use heating systems that produce 40 mm BTUs from a variety of fuel sources including steam, shavings, green fuel, and natural gas. This flexibility allows mills to burn the fuel that gives them the most savings. 

The USNR Green Fuel Burner “gasifier” can be manufactured as a hybrid burner using a combination of green sawdust and natural gas independently in the same system. Mills can switch between fuel sources to take advantage of price fluctuations and other market conditions. Having more fuel source options also lets companies continue drying through quarterly clean outs by using gas.

USNR has manufactured dry kilns for over 100 years, and today has the largest installed base in North America, says the company.

MuehlboeckCanadaMuehlboeckCanada

One of the biggest cost factors in producing lumber is thermal energy. With Muehlboeck’s drying systems Type 1003, already in operation at many sawmills, these costs are reduced by about half, says the company. The energy in the exhaust air is used for the drying process in a different part of the kiln.

The automated door system ensures heat loss is greatly reduced, but more importantly high capacity, high quality lumber output is guaranteed.

Muehlboeck’s innovative continuous dry kiln (CDK) systems, such as Dynamic & Flow, also bring logistic yard benefits due to automatic unidirectional lumber transport with custom-made buffers for loading and unloading, which reduces operating costs by eliminating the need for nighttime forklift operation.

Because of these advantages, Delco Forest Products Ltd in New Brunswick decided on one of Muehlboeck’s largest CDK’s for 100 million board feet. Installation is currently being completed.

Logging and Sawmilling Journal
October 2019

On the Cover:
James and Susan Willis manage J.A. Willis Contracting with ambition, strict business acumen, with a focus on efficient and productive equipment and highly motivated operators—it’s a powerful formula. Part of their core equipment is a Tigercat 845 harvester James first started using in B.C.—and continues to use in the logging operation they now run in New Brunswick, which now has a staggering 70,000 hours on it. The Willis logging operation also includes some recently acquired equipment such as the new Peterbilt truck with BWS quad trailer pictured on the cover. Read all about the Willis operation beginning on page 18 of this issue (Cover photo by George Fullerton).

B.C. hard hit by mill closures, curtailments
British Columbia—particular the Interior of the province—has been hit hard by sawmill closures and curtailments, and it is having a definite, and big, ripple effect on the logging sector, says the new general manager of the Interior Logging Association, Todd Chamberlain.

First Nations keeping the wood flow happening
First Nations and Métis communities are playing a key role in keeping the wood flow happening at Tolko Industries’ OSB plant in High Prairie Alberta, with a First Nations corporation managing all the log yard activities at the operation.

Opting for off-species
New Brunswick’s Tony Boyd took a somewhat circuitous route to sawmilling, via the trades and logging, but he’s now established a solid business producing custom wood products from a variety of off-species in the region.

A logging package that delivers
James Willis has logged in the West and East, working with the same dependable, productive Tigercat 845 buncher, though these days he has a new Log Max 6000V head, and opted for the Rotobec continuous rotator, a package that delivers the goods.

Taking care of business
B.C.’s Homalco First Nation is looking to build up its forestry operations, to make optimum use of their logging equipment—and to continue to grow its business and provide jobs and training for the band’s members.

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

The Last Word
Canada’s softwood lumber negotiating strategy is hurting, not helping, forestry workers, says Tony Kryzanowski.
