The role of horticultural carton vent hole design on cooling efficiency and compression strength: A multi-parameter approach

摘要: Abstract Forced-air cooling (FAC) is used to rapidly remove the field heat of horticultural produce better preserve quality. Cartons are ventilated promote uniform packed and minimise energy by precooler fans. The resulting efficiency influenced area configuration carton vent holes. However, placing holes also reduces compression strength, which requires reinforcement using additional fibreboard, thereby increasing manufacturing costs. This study, therefore, applied a multi-parameter evaluation approach assess four designs, each for three hole areas corrugated fibreboard grades. Computational fluid dynamics (CFD) was evaluate airflow resistance, rate, uniformity package related consumption. Experiments were quantify box strength. Results mechanical strength showed negative linear relationship between area. effect on dependent grade. For cartons trays, Multivent design 58% less FAC significantly improved compared Standard design. significant improvement in efficiency, enables match or improve design, considerably smaller ventilation study thus demonstrates importance incorporating developing packaging with optimised designs.
