Abstract:
In India, sapota grading is predominantly carried out manually through hand-picking or sieves, making the process labor-intensive, inefficient, and prone to inconsistencies. Mechanical grading offers a more effective solution by sorting fruits based on their physical dimensions, ensuring uniform size and shape, which facilitates easier packaging and handling. This study evaluated the performance of a mechanical weight grader for two sapota variety Cricket Ball at varying speeds (10, 15, 20, and 25 rpm). For the Cricket Ball variety, the optimal speed was found to be 20 rpm, achieving a separation efficiency of 93.8% with a feed rate of 7.23 kg/min. The results demonstrate that mechanical grading ensures higher efficiency, consistent quality, and reduced labor dependency, making it a cost-effective operation for post-harvest management of sapota.
