Title: Effect Of Peripheral Openings On Cooling Efficiency Of Horticultural Produce

Abstract: Due to the significant level of losses of horticultural produce during post-harvest operations, the reduction of the general process costs and the conservation of the produce quality are intensely searched. Among these processes, precooling plays an important role in the achievement of the latter two objectives. In turn, the precooling efficiency is decisively affected by the design of the container. The aim of this research was to quantify the effect of different container opening configurations for forced air precooling efficiency. The designs were evaluated based on the response of the rate and uniformity of cooling, and air pressure drop across the container and the produce. A comparison was made between eight configurations, which were formed by combining four total venting area percentages (0.67, 2, 4, and 8%) and two distributions on the package surface (peripheral and central). The tests were conducted under five airflow rates ranging from 0.125 to 3.9 L.s The results allowed the determination of the effect of the opening configuration on the cooling rate and uniformity through the entire horticultural produce package.
