Abstract
In the buckwheat industry, buckwheat sizing effect has played a significant role in the subsequent hulling effect and food quality in its deep processing. In order to study the influence of inclination angle of linear vibrating screen on buckwheat sizing effect, EDEM was used for numerical simulation of sizing process with the inclination angle of the screen separately at 2°, 3°, 4°, and 5°. By observing particle distribution on the screen deck and calculating the different types of particles in various statistical areas, qualitative comparison and quantitative analysis on the conveying capability of the screen and the penetrating capability of particles at different inclination angles were made, and the results revealed that with the increase in the inclination angle of the screen, the conveying capability of the screen was enhanced, while particles became less capable of penetrating through the sieve. When the inclination angle was increased from 2° to 3°, the conveying capability of the screen was significantly improved, while the penetrating capability of particles on both screen decks was slightly reduced. By taking the penetrating capability of particles and the conveying capability of the screen into comprehensive consideration, it turned out that better sizing effect would be achieved at the inclination angle of 3o. Our research will provide a reference for optimizing the processing parameters during the vibrating separation of buckwheat.
