SYSTEMS AND ENGINEERING FOR THE DEHYDRATION INDUSTRY

           

This is where we keep you advised of our recent newsworthy events and Westec America system developments and start-ups.

Flakeboard America Inc. (formerly Weyerhaeuser Company) – Duraflake in Albany, Oregon has installed two Westec Three Pass Rotary Dryers and related M.A.C.T abatement air systems for their Particle Board plant expansion Project.   The dryer systems include a 62ft. long “Face” Dryer as well as a 70ft. long “Green” Dryer – each capable of drying up to 70,000 O.D. lb/hr of wet wood particles.  Westec supplied all of the Mechanical Design, Dryer Components, Control Logic and Structural Engineering for the Dryer Systems and their supports.  Both dryer-systems were commissioned at the end of 2006.

 

           

Langboard Corporation in Quitman, Georgia has installed two Large Westec Single Pass O.S.B. rotary dryers and related air systems for their O.S.B plant expansion Project.  Westec supplied two 16ft.diameter x 84ft. Long Single Pass Rotary Dryers, all of the dryers’ air system components, Control Logic, Mechanical and Structural Engineering.   The systems were commissioned in 2005.

Plum Creek M.D.F. - Columbia Falls, Montana started operation of their No. 2 continuous M.D.F. press line.  The Westec fiber dryer comprises a large 84 inch by 350 ft. long tube followed by a second-stage drying tube that is 45 inch diameter.  Both dryers’ heating is from a sanderdust burner with Westec blending furnace and hot gas clean-up systems.  The Westec second stage dryer exhausts back into the first-stage dryer inlet.  The first-stage dryer exhausts (270,000 ACFM) into a wet scrubber and then into a large bio-filtration system.  The Westec systems reached full design production levels in late 2001 and has from it’s initial start-up met the customer’s requirements and expectations.

Boise Cascade Corporation, Elma,Washington has installed a Westec Three Pass wood flake drying system for their new wood plastic composite siding plant located at Elma, Washington.  The Westec drying system was selected because of its very low drying temperatures along with its low exhaust emissions and fully recycled operation.  The system started up in the spring of 2002.

Weyerhaeuser Company has contracted with Westec to provide assistance with the application and interfacing of RCO abatement devices at ten (10) of their panel manufacturing facilities.  Westec provided layout, design, and engineering assistance in order to concentrate and minimize exhaust volumes from the existing processes before they are abated in the RCO equipment.  Westec’s design included press enclosures for VOC capture, including drying system, recycle systems, and dryer air system upgrades.  The work included design of interfacings between existing emission points and the RCO inlet.  Systems were applied at Zwolle, LA; Emerson, AR; Dodson, LA; and Chester, SC veneer mills; and at Malvern, AR and Eugene, OR; M.D.F. plants; and at Simsboro, LA; Bend, OR; and Albany, OR particleboard plants.

Weyerhaeuser Company at their Heaters, West Virginia O.S.B. plant continues to set new production and quality levels in one of North America’s largest O.S.B. mills.  The mill uses four Westec three plus three-pass rotary drums for drying their surface and core layer strands.  The dryers are wet wood fuel heated and are abated to the highest industry standards.  The dryers operate at low temperatures (700oF to 900oF) and provide soft handling of the mixed hardwood strands.  The three plus three dryers represent the most advanced and cost effective technology for low temperature O.S.B. strand drying.

Ainsworth Lumber Company Ltd., Grand Rapids, Minnesota has taken delivery of a second pair of Westec O.S.B. Three-Pass strand drying drums.  The addition of these two high strand capacity drums completes their conversion to all Westec drying systems.  The dryer conversions were made to increase strand drying production.  The plant reports dryer throughput increases of 15% to 20% over the replaced conventional three-pass drums.
