Process Equipment

Explore new possibilities to enhance your processing efficiency. Rocky DEM is being used to improve everything from drugs to food, and from specialty chemicals to biofuels.

Overview

Rocky DEM is the most powerful solution for companies in the food, pharmaceutical and chemical industries to optimize the performance of their processing equipment.

Rocky DEM enables processing industries the world over to accurately simulate and analyze the behavior of bulk solids, boosting their performance.

Applications applications

Coating

Simulate real-scale equipment using custom polyhedral particles that model pill/tablet coating processes, including covering homogeneity.

  • Polyhedral elements

    Accurately predict dynamic bulk behavior of tablets and pills. Polyhedron models eliminate artificially bumpy surfaces that can significantly affect particle dynamics.

  • Collision statistics

    Improve equipment design to reduce breakage via collision statistic data analysis.

  • CFD–DEM coupling

    Run coupled Rocky–Ansys Fluent simulation during the coating process to account for convective heat transfer with hot/cold airflow.

  • Liquid film modeling

    Model liquid-film-spray injection and drying to evaluate coating homogeneity system-wide — all while accounting for liquid-bridge adhesion forces.
