| Resumen: |
The aim of this work was to determine natural convective heat transfer rates in bottled liquid food pasteurized using different container orientations; conventional vertical, inverted vertical, and horizontal bottle positions. For this purpose, a computational fluid dynamic (CFD) model was applied to predict the temperature distribution, flow pattern, and quality changes in non-Newtonian fluid foods for three orientations. The numerically predicted temperatures were successfully validated against experimental data and the model allowed to identify the critical point during the thermal
process. Results showed that the fluid flow developed in a horizontal orientation provided a better mixing of liquid food and, hence, a more rapid heating of the slowest heating zone compared to a vertical position. Moreover, the horizontal orientation achieved a 47.2% reduction of processing time and quality losses decreased (45.5–46.4%) with respect to a vertical position. These results suggest that a horizontal position could be considered as an interesting alternative for food processors since processing times can be reduced improving the final quality of the product |
