JBW was retained to provide design engineering, analysis, and design services for the dryer upgrade at an OSB facility. This project included the analysis of a complex air-material separation system with high-heat and humidity that is integrated with environmental controls.

​

The dryers take wet flakes at 50% moisture and dry it to 5%. The water removed from the flakes is absorbed in the hot air, which is then separated from the dry flakes in a cyclone system. The hot, moist air goes on to be further separated in 3 more stages for environmental compliance.

​

JBW analyzed the system, which hadn't run properly for years, and ultimately suggested removing 2 fans from the system to achieve the pressure desired in certain locations.

​

The JBW team provided BIM coordination for the new dryers (which were larger than the originals), construction drawings, design and engineering of support system, spark detection and extinguishment, and a heat reclaim system. Structural design was provided for the new dryer foundations and platforms.
