Food Processing

Enhance productivity by exploring granular flow behavior — the foundation for optimal quality, capacity, safety, and efficiency. Rocky DEM’s accurate particle representation is the key.

Overview

Innovative food processing technologies rely on modeling for designing and optimizing operational parameters as well as regulating product quality and safety.

Rocky DEM supplements experiments and empirical models, providing input to mixing, coating, granulation, sorting, drying, and packaging processes — reducing development costs and shortening time to market.

Applications applications

Coating

Simulate real-scale equipment by using custom polyhedral, shell and fiber particles that model chip, nut, and candy coating/seasoning processes, including covering homogeneity.

  • Polyhedral elements

    Accurately predict dynamic bulk behavior. 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 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.

Mixing and blending

Rocky DEM accurate predicts mixing- and blending- equipment efficiency, enabling increased batch sizes, reduce blending times, and minimal segregation.

  • Greater productivity

    Optimize mixing-device design to reduce blending time and increase productivity.

  • Upscale equipment

    Apply DEM to evaluate the best upscaling strategy, from lab to commercial.

  • Add complex motions

    Simulate complex, combined-geometry motions using Rocky DEM’s fully integrated motion kernel.

Controlling Discharge

Rocky DEM simulates real-world bulk-flow regulation, helping to keep flow rates at levels appropriate to the process.

  • Realistic particle shapes

    Accurately predict bulk material dynamic behavior using polyhedral or shell particles.

  • Improve hopper discharge

    Evaluate discharge flow pattern to both eliminate stagnant zones and mitigate degrading-material problems.

  • Evaluate feeders and valves

    Optimize valve/feeder designs for uniform hopper drawdown.

Drying and Heat Exchange

Rocky DEM particle simulation accurately models both conductive and convective heat exchange — as well as drying processes — for bulk materials.

  • CFD–DEM coupling

    Rocky-Ansys Fluent coupled simulations enable analysis of convective heat transfer between particles and fluid.

  • True physical representations

    Increase simulation accuracy with realistic particle shapes that account for collisions and fluid forces.

  • Multi-GPU processing

    Leverage multi-GPU capabilities to handle huge cases with millions of particles.

  • Liquid film modeling

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