The purpose of this research was to develop and fabricate prototype of Coconut Grater- Milk Extractor Machine combining those two existing machines to produce the coconut milk. In current practices on the market today, in order to produce coconut milk, two separate machines are used such as coconut grater machine -to get grated pieces of coconut milk and then the coconut extracting machine - to get the coconut milk. More specifically, the aim of this study were: (1) To determine the extracting efficiency of the coconut grater - milk extractor machine. (2) To determine the time in grating and extracting of the coconut using a coconut grater - milk extractor machine. (3) To determine if there is a significant difference in the performance of the coconut milk extractor machine as compared to the existing means in terms of: a. Extraction Efficiency, b. Time to finish a specified amount of coconut to milk. The statistical tool used in the study were the mean and the t-test. Based on the data gathered, it was concluded that there is a significant difference between the mechanical coconut grater- milk extractor and the existing means. Further study is recommended to improve the extraction improve the efficiency of the machine.
