Drying Risk Assessment Strategies

Abstract

This article highlights drying risk assessment strategies showing details of the methodology involved and the various tools used at risk assessment. The methodology suggested is to apply qualitative risk assessment with risk estimation used for qualitative ranking of recommendations. The methodology suggested follows to a large extent the general procedure for risk assessment of machinery and the application of modified the “What-if” hazard method with the risk estimation by a multi-layer risk matrix technique. As an example, a case study of risk assessment for the typical two-stage spray-fluid bed dryer to produce milk powder is presented. The analysis shows how an acceptable risk level may be achieved by the introduction of risk reduction options.
