The Design And Developing of Dice Carrot Size Sorting Machire : A Case Study of ABC Co.Ltd

Abstract

The objective of this research was to control the quality of carrot size screening in 10 millimeters by designing and developing a prototype of a dice carrot size sorting machine with cost savings and economic efficiency. The design and development of the dice carrot size sorting machine prototype had a size of 25×20×51 centimeters, respectively. Prime Movers needs 90 watts of electric motor. The result of the research has shown that by sorting the size of a diced carrot with 8 human laborers, the production capacity is 297 kilograms per day. The prototype of a dice-carrot-size sorting machine using a 90-watt motor along with two human laborers for placing plastic bags in the machine will have a production capacity of 51.36 kilograms per day. By using 90 watts of dice sorting machines, their production capacity of 17.29% is less than that of 8 human laborers. By increasing the power of the machine motor to 746 watts, the production capacity increased to 425.71 kilograms per day, which amounted to 67.76 percent compared to the labor force. And the overall equipment effectiveness of the carrot-size screening machine prototype was 92.94%. Economic analysis shows the break-even price of the product is 425.71 kilograms per day and the payback period is 26 days.
