Development of tuna fish grater machine for shredded fish industrial of household scale br

This study aims to develop a fish grater machine to produce shredded fish on a household scale. The development of this fish grating machine considers getting the maximum capacity, minimum percentage losses, maximum percentage of the sample that grater with size short and middle grade, and maximum percentage of the sample that grater with size rough grade with limited sources specified power. The method used in this research is the machine manufacturing and testing approach. Three types of grater teeth (K-type, P-type, and B-type) are the main focus of this research to optimize the quality of the grater and the performance of the machine. The machine capacity, the percentage of losses and the optimal quality of the counting size of the developed machine can be achieved using a K-type grater. Analysis of variance and the t test are used simultaneously to determine the optimal performance of this machine. The results of this study suggest that using a K-type grater is the most suitable grating machine for shredded fish.
