  2. Sorting/Grading • Process of categorizing fruits and vegetables according to quality Grading • Manual • Mechanical • Qualities graded • Size • Mass • Colour • Profile

  3. Diverging Roller Grader • Working • Fruits/Vegetables roll between diverging rollers • Pushed forward by the roller gradient • Fall between the rollers as the slot size increases • Location of fall determines the size of the sorted produce • Bin/Tray is placed underneath the rollers to collect the graded produce

  4. Diverging Roller Grader • Applications • Pre-Grading • Grading • Ideally Suited for Citrus and other round fruits and Vegetables • Can be used for grading Potatoes and Onions • Not Suitable for Long Vegetables like Carrots and Radishes

  5. Diverging Roller Grader • Technical Specifications • Capacity: 2-3 Tons/Hr (Onions and Potatoes) • Frame Size: 1750 X 950 X 900mm • Max. No of Grades: 5 • Frame Material: Low Carbon Steel • Rollers: Stainless Steel 304 • Motor Type: ½ HP, Single Phase, Geared

  6. Diverging Roller Grader • Advantages • Lower Cost Compared to other graders • Simpler Mechanisms Result in Higher Reliability • Greater Flexibility in adjusting to different grade sizes • Lower Power Consumption resulting in greater savings in the long run • Can be operated where 3 phase supply is not available • Limitations • Cannot be used to grade longer vegetables like Carrots and Radishes • Limited Throughput
