The purpose of this research was to develop de-huller machine which can hull beans without broken parts. Specifically it sought to: 1. Find out the time rate of de-hulling; 2. Determine the efficiency of the machine; and 3. Find out the percentage recovery of de-hulled beans. Trial method was employed by the researchers which are within the realm or scope of true experiment. Statistical tools were utilized in the analysis of the data through the average value or mean. Mean was computed to determine the weight of coffee beans, time and percentage recovery of beans. The results shows that the machine made was found to be more efficient than the previous manual operated de-huller machine.
