| Summary: | Throughout the food industry, packaging development and optimum packaging design for
transporting perishable food goods and storing fresh produce can be challenging and tedious
tasks. It is crucial to maintain a specific temperature and airflow within the packaging system
of the perishable food product during storage or transportation to avoid quality degradation.
Preparation of packaging design test requires much complex work from the initial concept,
physical prototype, and testing process and until final packaging solution to meet the required
conditions. Nowadays, with the help of simulation tools such as computational fluid dynamics
(CFD) software, weeks or months of physical testing can be replaced by hours or even minutes
of a simulation run. This study will showcase a simulation work related to the food packaging
design solution using open source CFD software, OpenFOAM. For this case, the airflow and
thermal analysis for the ventilated packaging container for fresh fruits is investigated. This
work aims to present a CFD model to predict airflow and temperature distribution profiles in
ventilated packaging systems within the packaging container of fresh fruits. The simulation
runs are performed under different air inlet flow and different ventilation diameter holes. Based
on the preliminary result, the airflow distribution within the packaging box develops an uneven
temperature profile. The simulation approach will help us consider the optimal ventilation
configuration for proper ventilation efficiency by changing the ventilation position or modifying
the ventilation hole design. |
