2 Post peeling - what does it mean?
The two actual processes in Cashew processing Shelling (Removal of outer shell) Peeing (Removal of adhering testa) Further processes for marketability Grading Packing

3 Post peeling Challenges
Natural issues from RCN - Spotted Speckled - Immature - Dessert Yellow Oily - Rotten Manually sorted to White, Scorched and Scorched Seconds/Dessert. Manual process also upgrades the quality of Cashews, by scraping, cutting out spots, etc. Problems from the Factory - Shelling and Peeling Shelling: Loose Shell, CNSL contamination, Dust Peeling: Loose Testa, Adhering Testa, Dust Much more in Mechanical Shelling and Peeling Infestation

4 Post peeling Presently used technologies
Air Aspirator (Remove dust – Cashew are soft and generate dust in every stage) Sifting and Sieving (Remove small pieces) Gravity separator/Destoner (Remove foreign mater and stones) Optical sorting

5 Post peeling – Optical sorting
Colour sorting - Camera sorting (B/W, CCD, Infra-Red, NIR) - Laser sorting Optical size sorting (W240, W320, W450, etc.) Optical Shape sorting Final Quality Control – Metal Detection, X-Ray Detection Insect Control – Chemical and Low Oxygen Fumigation
