Abstract 
	An essential property, especially during storage, handling and processing of a particulate material is flowability in vessels, bunkers, and silos. The flowability as a property influences the creation of falls, such an arching, piping, rat-holing, sudden avalanching in a storage transport system. In addition, flowability more notably depends on environmental factors and often is constantly changing so that the powder behavior is not often predictable. 
	This paper deals with Coating (surface modification) a small amount of additive, and thereby decreasing the angle of internal friction, which is one way of improvement flow properties of storage particulate materials. Although flow property improving of a particulate material is achieved, issues such as the applicability for food industry and quantifying how much coating batch is necessary for optimal storage of transport conditions still remain.
