Effect of storage time and consolidation on food powder flowability

This paper presents an evaluation of the effect of storage time and consoli dation on the flowability of the following food powders: flour, tea and whe y permeate. Instantaneous and temporal flow functions of the powders were m easured to quantify the combined effects of compression stress and time. Th e how functions were measured using a Jenike shear cell and a consolidating bench. A number of powder physical properties, including moisture content, bulk density and particle size were measured. These properties are used in interpreting and comparing the flowability measurements for each powder. ( C) 2000 Elsevier Science Ltd. All rights reserved.
