Summary

Food transport and storage in an insulated box equipped with Phase Change Material (PCM) is common for last mile delivery; however, it was addressed as a weak link with high average temperature and high temperature heterogeneity. This experimental study investigated the effect of PCM position (at the lid and at a side wall) and the spacing underneath the load on the temperature profiles inside the box. PCM (water-based), air, surface and core temperatures of the load (test product made of methylcellulose) at different positions were measured every 30 seconds from loading until PCM totally melted. PCM position is a determining factor on the coldest and warmest position while the underneath space decreased the difference between the maximum and minimum core temperature. In spite that the average temperature was not affected by these factors, the presence of space below the load is essential for temperature homogeneity.
