| Abstract | ||||
| Onions considered one of the most important economic crops in Egypt. Onion grading is very important for its profit gain to the farmer. As it improves packaging and other post-harvest operations, manual grading of onions is tedious, labor-intensive, and causes many losses. The grading machine for onion evaluated in terms of grading efficiency, cost economics and onions damage percent for Giza 20 and Beheri varieties. The grading efficiency was 96.72%, 94.85 for Giza 20 and Beheri onions respectively, at 2.5 Hz, and at zero degrees an angle of inclination. The damage percent for onions was not observed at different grading conditions in this study. | ||||
