ABSTRACT
Hexagonal Evaporative cooler was designed,
constructed and tested using locally available materials. This was used in the
preservation of freshly harvested Vegetables. The capacity of1 the cooler was
0.135m3 Two tests including "No Loud Test" and “Load Test" were
carried out on the cooler. The "No Load Test” was carried out to evaluate
the effectiveness of the pad materials (jute, wood shavings and latex foam)
used. While the “Load Test” was carried out during preservation of Vegetables
with Jute pad material. Freshly harvested Okra (Hibiscus esculentus),
Amaranthus (Amaranthus spp) and Tomato. The maximum temperature drop of the
cooler was 12.5°C. The minimum and maximum dry bulb temperatures of the
cooler were 18.3 and 25°C. Jute pad was .observed to have the highest
saturation efficiency of 97% and humidTfication efficiency of 91.2%,and latex
foam 80.5% and humidification efficiency of 67.4%.The cooler was able to
sustain the weight and freshness of okra and amaranthus for 28 days. It was •
also found that the cooler was not suitable for the storage of ripe tomato.
