Abstract: ARARAO, ROSALIE PER1DO. Don Severino Agricultural College, Indang, Cavite, April 1994. "DESIGN AND EVALUATION OF A MULTI-PURPOSE DRYER USING AGRO-WASTE AS FUEL". Adviser: Engr. Camilo A. Polinga. An agro-waste fueled multi-purpose dryer was constructed in Mahabang Kahoy Cerca and evaluated at the Don Severino Agricultural College, Indang, Cavite from January to March 1994. Specifically, it aimed to design a dryer adaptable to small scale farmers; utilizing the most common agricultural waste as heating source for the dryer; evaluate the dryer's performance; and, determine its cost and return. The dryer consisted of the drying chamber, heating chamber, heat exchangers, furnace, and chimney. The dryer was evaluated using coffee, peanut, pineapple, and mango, while treatments used were coconut shell, wood charcoal, and coffee pulp. Results showed that the kind of fuel materials used in drying gave a highly significant effect on drying time, drying rate, and fuel consumption in drying some crops. Best result was obtained using wood charcoal as fuel giving the highest drying rate and the shortest drying time with smallest quantity of fuel consumed. Drying operation using wood charcoal gave average drying times of 25.545 hours, 9.64 hours, 11.64 hours, and 16.13 hours; drying rates of 3.72 %MC/hr, 3.05 %MC/hr, 6,55 %MC/hr, and 4.22 701C/hr; and, fuel consumption of 12.5 kilograms, 4,375 kilograms, 5.5 kilograms, and 7.0 kilograms for coffee, peanut, pineapple, and mango, respectively. The recorded drying temperatures using the same fuel materials ranges from 50 °C to 55°C for the whole drying operation. The cost of the dryer was 12 11.054.40. It has annual gross revenue of R 40,320.00 and net income of R 5,378.64. Payback period of the dryer was computed to be 2.06 years while the break-even point was 967.69 hours per year. The dryer has a benefit-cost ratio of 1.1. Results indicate that the dryer is applicable for commercial purposes.

ARARAO, ROSALIE PER1DO. Don Severino Agricultural College, Indang, Cavite, April 1994. "DESIGN AND EVALUATION OF A MULTI-PURPOSE DRYER USING AGRO-WASTE AS FUEL". Adviser: Engr. Camilo A. Polinga.

An agro-waste fueled multi-purpose dryer was constructed in Mahabang Kahoy Cerca and evaluated at the Don Severino Agricultural College, Indang, Cavite from January to March 1994. Specifically, it aimed to design a dryer adaptable to small scale farmers; utilizing the most common agricultural waste as heating source for the dryer; evaluate the dryer's performance; and, determine its cost and return.

The dryer consisted of the drying chamber, heating chamber, heat exchangers, furnace, and chimney.

The dryer was evaluated using coffee, peanut, pineapple, and mango, while treatments used were coconut shell, wood charcoal, and coffee pulp.

Results showed that the kind of fuel materials used in drying gave a highly significant effect on drying time, drying rate, and fuel consumption in drying some crops.

Best result was obtained using wood charcoal as fuel giving the highest drying rate and the shortest drying time with smallest quantity of fuel consumed. Drying operation using wood charcoal gave average drying times of 25.545 hours, 9.64 hours, 11.64 hours, and 16.13 hours; drying rates of 3.72 %MC/hr, 3.05 %MC/hr, 6,55 %MC/hr, and 4.22 701C/hr; and, fuel consumption of 12.5 kilograms, 4,375 kilograms, 5.5 kilograms, and 7.0 kilograms for coffee, peanut, pineapple, and mango, respectively. The recorded drying temperatures using the same fuel materials ranges from 50 °C to 55°C for the whole drying operation.

The cost of the dryer was 12 11.054.40. It has annual gross revenue of R 40,320.00 and net income of R 5,378.64.

Payback period of the dryer was computed to be 2.06 years while the break-even point was 967.69 hours per year. The dryer has a benefit-cost ratio of 1.1. Results indicate that the dryer is applicable for commercial purposes.
