Optimisation of multi-scale ventilated package design for next-generation cold chain strategies of horticultural produce​​


​Prof C Coetzee

Prof UL Opara (Horticultural Science)

The thesis applied a multi-parameter and multi-scale approach to develop improved designs and guidelines for fresh produce packaging systems. Specifically, the potential implementation of alternative vent hole designs that improve performance in the cold chain was investigated. Furthermore, a computational fluid dynamics model was proposed to characterise moisture content values and distributions in stacked cartons during refrigerated shipping conditions. This model will facilitate enhanced carton mechanical strength testing protocols in the future. Lastly, the challenge of loading refrigerated freight containers was considered and an improved packaging design system for fresh produce export was proposed.​
