Study on the Comparative Evaluation of Cashew Nut Shellers

Cashew nut recovery remains major concern in the cashew nut production. The hand operated portable cashew nut sheller was developed on the principle of shearing. The comparative performance was tested for hand operated cashew nut sheller, hand and foot operated sheller and manual shelling, the test results showed that hand operated sheller can shell 2.32 kg cashew/hr with the whole kernel recovery of 86.26 per cent. The per cent whole kernel recovery for new sheller was 86.26, while that for foot pedal operated sheller was 80.1 and hand shelling was 71.0.
