Now they have come with a machine, it contains different holes to grade and a cleaner. The raw onions from the field have to be spread on this machine, the cleaner will rectify the muds and sent them to the grader, there onions will be differentiated.

The cleaner and grader combinedly would cost about 90,000 Indian rupees approximately. S Revathi, an onion farmer from Narasipuram, said that the onion de topper would reduce labor costs by 50%
