<br/><br/> ESTACIO, JENELYN C. and FLORES, RIC KARL T. Design, Fabrication and<br/>Performance Evaluation of an Automated Onion Grader. Undergraduate Thesis. Bachelor<br/>of Science in Agricultural and Biosystems Engineering. Cavite State University, Indang,<br/>Cavite, May 2018. Adviser: Engr. Kevin P. Titiwa.<br/>An automated onion grader was designed, developed and evaluated at Cavite State<br/>University- Main Campus, Indang, Cavite. The primary components of the machine include the<br/>one-hp three-phase electric motor, hopper, sieve assembly, collection unit, counter unit and the<br/>main frame. This study was experimental in nature where the technical performance of the<br/>machine was limited to the determination of grading efficiency, grading rate, accuracy of<br/>counting, and machine's capacity. The grading efficiency of the machine was found to be<br/>maximum at 168-171 oscillation/min with 60.60 percent. The accuracy of counting of the<br/>machine showed a peak result at l 49-151 oscillation/min. On the other hand, the grading rate<br/>and capacity were highest at188-192 oscillation/min with 20.73kg/min and 37.87kg/min,<br/>respectively. The initial cost of the machine was P29, 952.00. The cost of grading would be<br/>P0.20/kg and the break-even point can be attained with at least 38,333.33kg of onions graded<br/>per year. The time it would take to recover the investment for the machine was 3 years.
