A machine was designed and developed for coconut milk extraction and its performance was evaluated at IIFPT, Thanjavur, Tamil Nadu. The milk extraction efficiency was found to be 78.27%. The milk yield was tested with three different nozzle clearance of 2, 3, 4 mm and rotational speeds of 40, 50 and 60 rpm. Finding saying that, the percentage of coconut milk yield was higher at the point of combination of the nozzle clearance of 2 mm with the rotational speed of 40 rpm which yielded about 49.03% of coconut milk. The lowest coconut milk yield of 33.38% was analyzed during the point of combination of the nozzle clearance of 4 mm with the rotational speed of 60 rpm. Both lower and higher percentage of coconut milk yield were having a significant difference (p<0.05) with other results. The experiment shows that the increase in rotational speed of the motor resulted in decrease in the milk yield. It was also showing that the average milk yield started to decrease while increasing the nozzle clearance (mm). Thus, our major research finding saying that, lower rotational speed and nozzle clearance result to the higher amount of coconut milk yield. The performance evaluation indicates the values of 30.52 kg/h and 0.041kWh/kg-grated coconut for average feed rate (FR) and Specific energy consumption (SEC) for the designed coconut milk extractor.
