Taste the Difference – A New Method of Measuring Segregation: Steak Seasoning, a Case Study
Bulk solid processing generally fails due to one of three problems: material may hang-up in the system, the flow rate cannot be controlled by volumetric feeders, or material segregates during processing creating quality problems. This paper focuses on diagnosing and solving segregation problems. Almost all bulk solid blends are a combination of three or more materials; yet our ability to measure and mitigate segregation tendencies in multi-component mixtures is significantly below our ability to create these mixtures. The paper presents a method to measure the segregation potential of a steak seasoning blend comprised of five components using spectral methods. This blend was chosen as a case study mixture to show the effects of segregation in multi-component systems. Changing the physical characteristics of just one component can often affect segregation of several components in the system. This paper shows how changing the size of the salt affects at least two other components.
