The portable evaporative cooler was designed for storage of 50 kg fresh fruits having overall diamentions of 1220 x 860 x 787 to study the performance of an on-farm evaporative cooler with the effect of different filling materials viz., coconut coir, saw dust + gunny bag, ECC cool pad, wala sheet and gunny bag. Selection of filling material was based on the cost, water holding capacity, rate of evaporation of water from filled material and easy availability. Sapota (Cv. Kalipatti) fruits were stored in an on-farm evaporative cooler for 16 days. The effect of filling materials on Physiological weight loss (PLW), inside temperature, inside relative humidity and cooling efficiency of five filling materials were studied. The weight loss varied between 2.50 to 13.29, 14.96, 15.37, 15.36 and 15.20% in coconut coir, saw dust + gunny bag, ECC cool pad, walasheet and gunny bag, respectively. The mechanical test such as cooling efficiency for each filling material was determined and it was recorded as 90%, 54%, 38%, 70% and 79% for coconut coir, saw dust + gunny bag, ECC cool pad, walasheet and gunny bag respectively. Minimum inside temperature of 16.5 to 17.20C and maximum inside relative humidity of 97 to 90% was recorded in coconut coir of an on-farm evaporative cooler when ambient temperature was 27.660C and ambient relative humidity was 51%.The maximum storage life of 16 days was found in coconut coir. Coconut coir was performed better when compared with other filling material. It was most economical filing material over the other filling materials.
