CASE STUDY
Confection processing within Mars Inc. is very complex. To
optimize and understand the physics, we use DEM, CFD, and
structural simulation. For example, modeling the Skittles or
M&M coating process — in which we must account for dynamic
flow of the actual candy shape, interaction between candies,
spraying and drying them, and accurately predicting the coating
distribution and crystallization growth — is paramount.
Rocky DEM coupled with ANSYS CFD captures these phenomena
using liquid bridge models, heat and mass transfer. This allows
Mars to migrate its process simulation models into a single,
integrated and high-productivity workflow, enabling quicker
simulations to be done in a much faster response time."
