The x-ray imaging based mango sorting system uses a totally nondestructive indigenous technology employing X-ray imaging technique to sort the mangoes based on internal disorders in real time. The X-ray scanned mangoes are safe for consumption without any health hazards. Salient Technical Features: ? Detection of internal defects like spongy tissue and seed weevil in post-harvested mangoes. ? Image processing methods employed for sorting. ? X-ray imaging system integrated with mechanical feeding conveyor, rejection assembly, software and hardware modules. ? On-line grading and sorting of 3600 mangoes per hour approximately (about one ton per hour) on prototype model. ? Defect detection accuracy of 95% and above.
