Small-scale Demucilager Machine for Arabica Coffee (Coffea arabica)

Natural fermentation is time- and water-consuming, laborious, causes weight loss in the coffee beans. It conventional method to remove mucilage Philippines that can take up 48 hours. This study aimed develop a small-scale demucilager machine evaluate its demucilaging capacity, efficiency, product recovery, damaged parchment coffee, electrical power consumption. also compare use of natural terms processing time, human labor, water The developed continuously-fed horizontal separates from by abrasion. consisted following components: hopper, which receives freshly depupled coffee: cylinders, separate supply system delivers hopper cylinders: output chute, discharges transmission system, transmit electric motor machine: and, frame, holds other components place. Evaluation results showed has 37.87 kg/hr 79.0% 4.87% damage, 96.96% 41.54 W-hr energy consumption at 1.23m/s peripheral speed 0o inclination. reduced time 12-24 hours using 2.64 machine. Human labor was 4 2 operators Water 0.87-1.60 L/kg 0.22 L/kg, respectively. Lastly, economically feasible custom rate 1.75 Php/kg with break-even 11,517.00 kg/yr. payback period 2.49 years benefit-cost ratio 0.62.
