Abstract

Objective: In order to analyze the movement and mixing characteristics of food powder particles in the double-shaft paddle mixer to optimize the verification of the mixer structure. Methods: The EDEM software was used to simulate the proportional mixing of three different sizes of food powder particles, and then Bin Groups would build a mixing box to observe the mixing situation, and evaluate it by studying the number of particles between different types of food powder. Results: At t=5 s, there was still a certain gap in the number of particles in the squares corresponding to the three types of powdered food particles, but the difference was basically the same. The mixing degree of the three types of powdered food particles was already very high; The change trend of the contact between food particles over time was basically the same. As time increasing, the number of contacts between various powdered foods also increased. After t=8 s, the number of contacts between particles between various powdered foods basically reached a stable value. Conclusion: The discrete element method can effectively analyze the mixing of powdered food in the paddle mixer.
