Creation and Efficiency Determination of Dried Stolephorus Sorting Machine

Abstract

This research aimed 1) to design a sun-dried anchovy sorting machine, 2) to measure efficiency of the sun-dried anchovy sorting machine  and 3) to examine satisfaction with the sun-dried anchovy sorting machine invented by the researcher.  The findings revealed that the sun-dried anchovy sorting machine is designed to have size of 800 x 1,900 x 1,200 millimeters (width x length x height) driven by a 220-Volt AC motor with 1/2 horsepower, and velocity of 1,400 rounds/ minute. It is equipped with a sieve at size of 740 x 1,700 x 223 millimeters (width x length x height) of which the holes’ diameter is 10 millimeters, and the number of sieve holes is 4/1 square inch with 3-degree slope. Finding performance of the sun-dried anchovy sorting machine, the researcher realized that after sorting 5 kilograms of dried anchovies, the dried-anchovies of 4.73 kilograms and fish scraps of 0.23 kilograms were obtained. Meanwhile, the sorting of 10-kilogram dried anchovies produced 9.52 kilograms of dried anchovies and 0.40 kilograms of fish scraps on average and the sorting of 15-kilogram dried anchovies produced 14.32 kilograms of dried anchovies and 0.59 kilograms of fish scraps on average. Additionally, when sorting 30 kilograms of dried anchovies the researcher obtained 28.57 kilograms of dried anchovies and 1.22 kilograms of fish scraps on average. Therefore, the performance of the sun-dried anchovy sorting machine was 95.23%. Regarding satisfaction with the sun-dried anchovy sorting machine among 30 samples, the average satisfaction was 4.38, which was at very good level (SD = 0.62).
