For applications where drying sensitive material is required, the Charles Brown Company steam tube dryer is an ideal match. Steam tube dryers typically operate at lower temperatures and rotate at slower speeds. This exposes the product to a larger heat transfer area than a typical direct heat dryer enabling material to gradually heat throughout rather than drying and hardening the external surfaces of the product. Steam tube dryers utilizing steam rather than hot gas and its direct heat source has enabled the steam tube dryer to operate up to 95% thermal efficiency. In some instances, the steam tube dryer method is superior to other direct and indirect heat methods. The Charles Brown Company steam tube dryers are constructed with miles of steam tubing built right in, protected by manifolds that cradle the steam tubes with industrial strength tube supports. All manifolds are tested and "U" stamped as per ASME Division I requirements. • The Charles Brown Company steam tube dryer can operate in both parallel and counter-flow arrangements.
