The raw cashew nuts collected from the growing areas are moved to the factories for processing. It is ensured that the raw nuts are thoroughly cleaned and are free from all foreign matter before they are taken for processing. The processing of cashew is done by any of the four methods
- SUN DRYING: The raw cashew nuts are simply dried in the sun for a few days and shelled with out temp.
- DRUM ROASTING: In Drum Roasting, the nuts are heated at high temperature is a rotating drum and then shelled.
- OIL BATH ROASTING: In this method, the nuts get roasted in a bath or cashew shell liquid and also the cashew nut shell liquid (CNSL) is extracted.
- STEAMING: It is another improved method adopted in Cashew processing. The nuts are steamed so as to make the shell soft and then cut open to get the kernel. The roasted /steamed rawnuts are opened by cutting or by using mallets and the testa is then removed after drying in a borma. The peeled kernels are then graded by size, shape and colour and packed for exports.
