Abstract
Computer simulation has possibility to give us useful information in development and improvement of grain processing technology. In discrete element method using elliptical elements a method to easily obtain a contact point in particle contact was proposed. Experimental results using a small scale model and simulation results using circular and elliptical elements at the same scale on shaking separation phenomenon of paddy and brown rice were compared in the change of separation condition with the inclined angle of a separation box. Good agreement between experimental and simulation result using elliptical elements suggested effectiveness of the elliptical model in a design of grain processing technology.
