AIRFLOW AND UNIFORMITY Can Be Key Drying Considerations

Asphalt mixture samples, for example, must be heated and dried to determine moisture content in the mix as part of the quality control process during road construction and repair. While a kitchen range or a low cost static industrial oven can technically meet the uniformity requirements of these test specifications, only a high quality forced convection industrial oven with precise control and uniform performance will ensure accurate, repeatable test results. [...]if an application generates heavy amounts of moisture or involves drying solvents, the role of proper ventilation and the design of the exhaust system must be considered. Whether an industrial drying process is mundane or highly specialized to overcome difficulties and optimize a process, oven buyers should to pay close attention to the characteristics that lead to high accuracy and process repeatability: control system and physical design. # Rolf Kragseth is an applications engineer with Despatch Industries, Minneapolis, a manufacturer of industrial ovens and other thermal products.
