EFFECT OF POT IN POT COOLING SYSTEM ON THE STORAGE LIFE OF OKRA (ABELMOSCHUS ESCULENTUS)
Evaporative cooling system is a physical phenomenon in which the surrounding air cools an object or a liquid in contact with it. An extensive literature has been reviewed. The materials and methods used in the research involves, the two clay pots (bigger and smaller size), water, Okra, measuring devices (Thermometer and Hygrometer), and the wooden cover. A smaller pot was kept inside a bigger clay pot and the Inter-space was filled with river-bed sand which was made moist by adding water thrice a day i.e. morning, afternoon and evening. The result obtained showed that the okra can be stored for 14days in the mean temperature of (27.27, 32.92 and 29.68 OC) and relative humidity of (97.43, 47.08 and 66.30 %). Conclusively, the pot in pot evaporative cooler could be used in New Bussa, Nigeria during the dry season when the temperature is high and relative humidity is low.
