Development of discrete element simulation method of vegetable oil press

Abstract

During the process of plant oil extraction major part of the power input transforms into thermal energy caused by friction. The evolved heat has a very significant effect on the quality of the oil. Our aim is to approach the real pressure and thermal phenomenon with the support of discrete element method (DEM) simulations. In the present stage of our research we have created a model with more complex geometry which represents the next stage of the evolutionary model development. The article presents our newest results.
