The mixing efficiency of a binary mixture in a rotating drum was evaluated using image analysis and a mixing index. Two different varieties of food were tested in this experiment to observe how they would flow and mix a rotating drum. The physical properties of granular materials were measured in a horizontal rotating drum during the slumping motion angles of repose of dynamic. The angles of dynamics are investigated as a function of rotation speed, degree of filling, and drum diameter. Mixing quality is a physical property that may be used to evaluate a mixing procedure. To compute the mixing index, image analysis is required to establish the mixing time and efficiency. After a certain amount of mixing time, the mixing efficiency is measured by a sufficient number of picture analyses. The granular materials in this experiment have different particle shapes, sizes, volumes, densities, and colors to investigate whether there is a difference in the image analysis program. The RGB color of the cutting picture was analyzed using the image processing tools given by TinEye color extraction software, which is based on MATLAB code. This application calculates the binary mixing color percentages. To further investigate the process, a mixing index is utilized to measure the evolution of mixing. The development of mixing efficiency throughout the mixing process is quantified using a mixing index. A genuine mixture’s mixing index M ranges from 0 (completely separated) to 1 (Totally randomized).
