Abstract
An adhesion model in Distinct Element Method (DEM) for mixing of food powders having different adhesive forces was developed. It is necessary to determine which adhesive force should be applied in the DEM simulation when the particles having high adhesive force and particles having low adhesive force during mixing come in contact with each other. The simulations of mixing behavior of particles having high, low and their average adhesive forces were performed to discuss the effects of adhesive forces on mixing behavior. While, in order to compare to the mixing behavior simulated, two types of mixing experiments of salt and potato starch, and wheat flour and potato starch which have different adhesive forces were carried out. As a result, it was found that when the particles having different adhesive forces contact, the mixing behavior and mixing index of the simulation using the values of high adhesive force would be in agreement with those of the experiment.
