Simulation of airflow and particle motion in a direct-flow spray dryer

The airflow motion in an upright direct-flow drying chamber is modeled with a heat carrier centrally fed to a cone of centrifugally sprayed dry milk particles. The calculations to describe this process are presented. Taking account of the gas dynamics of submerged jet motion, the derived dependences...

Zusammenfassung:The airflow motion in an upright direct-flow drying chamber is modeled with a heat carrier centrally fed to a cone of centrifugally sprayed dry milk particles. The calculations to describe this process are presented. Taking account of the gas dynamics of submerged jet motion, the derived dependences are compared with the results of testing a commercial spray dryer with a capacity of 500 kg of evaporated moisture per hour.
