Summary

In fresh produce precooling applications, an important feature of packaging design are the vents that allow airflow within, between and through stacked packages. The pressure drop through an orifice (i.e. a vent) can be characterised in terms of a loss coefficient and numerous correlations exist to predict this in literature, which theoretically can be used to predict the airflow distribution for a given packaging system. However, many such correlations were developed for orifices with much larger total open area (TOA) than are typically encountered in packaging vents (2 - 8%) and do not account for apparently significant vent design parameters such as number of vents, and location on the packaging face. In this work, the pressure loss coefficient for different vent designs were measured and compared with literature sourced coefficients. In addition to vent size, results presented consider and describe the influence of number and location of vents on the package.
