Abstract: The A.A.I. design longitudinal slot type Potato grader was modified and a new prototype was fabricated. The slope of sieves and their oscillating speed were standardarised to achieve higher degree of grading efficiency and capacity. The thicker rubber beeds have been provided to minimize the Potato damage. After above modification the Grader was tested. Based on the least slippage percentage and at minimum vibration of machine the suitable oscillation rate of sieve was found to be 385 per minute for efficient functioning of machine, maximum grading efficiency of 99.40 percent and a grading capacity of 30.92 quintal per hour was achieved. The energy consumption of Potato grader was found to be 0.025 kwh per quintal.

Keywords: Grader, cultivation, porosity, feeding hopper and sieves etc.
