Abstract

Abstract: For packaging processes of food and drug powders safety and cleanliness of the final product is one main aspect of the manufacturing process. To reach longer life periods of the products many of these processes are using inert gases during dosing procedure. To examine the entrainment of different kinds of gas species by free‐falling bulk material during the dosing process an experimental setup was built. Therefore different particle‐size distributions as well as different falling heights were analysed. The achieved results are used for the validation of numerical simulations based on different numerical methods.
