Use, Impact, Design, and Fabrication of an Onion Sorting and De-Topping Storage Machine

Due to the development of new avenues for the sale of agricultural commodities, Sri Lankans are now more concerned with the open market at competitive prices as the quality and value addition of agricultural products have improved. A significant method of adding value to the majority of agricultural products is size-based grading. The cost of the various agricultural products also varies greatly depending on how uniformly they are sized. In addition to improving the produce's processing properties, uniformity in size increases its consumer appeal. Currently, crop collectors, entire sellers, and retail sellers manually grade the sizes of the majority of agricultural crops, including large onions. The majority of farmers sell their goods without any sort of grading. Collectors, whole sellers, retail dealers, and farmers who handle post-harvest crops in Sri Lanka are less likely to employ expensive and sophisticated grading techniques. Additionally, a local market investigation revealed that the retail prices of large onion bulbs vary greatly depending on their size.
