This firm has developed a new (patent pending) Dual Feed System for its Swirl Fluidizer dryers (photo). The new system allows very-low-viscosity and thixotropic feeds to be dried to produce a powder with consistent moisture content and product quality. The Dual Feed System uses the mixing that already takes place in the drying chamber, driven by its rotating disintegrator. One feed carries the liquid feed product to the drying chamber; the second carries dry powder pneumatically or by screw feeder. The two inlet streams are arranged so that the powder is immediately mixed with the liquid feed so that the moisture is distributed over the entire available powder surface. — GEA Niro, GEA Process Engineering, Inc., Columbia, Md.
