Development of Chironji nut (Buchanania lanzan) grader-cum- decorticator

PDKV Chironji nut Grader cum Decorticator (CNGD) machine consists of grading hopper, decortication hopper, sieve assembly, outlets, and motor. The performance evaluation for Grading unit was optimized with 39 experiments. The performance evaluation for Decortication unit were optimized with 29 experiments. The experiments were generated through Box-Behnken Design and the experimental data was analyzed by applying Response Surface Methodology (RSM) using Design Expert 12.0.8.0 software for optimising the input parameters. The optimized input parameters of700 rpm oscillating speed of sieve assembly, 180 kg/h feed rate and three sieves each of diameter 9, 7 and 5mm showed the grading efficiency of 98.81%. The optimized input parameters of8% wb moisture content of nut, 80kg/h feed rate, 750 rpm speed of disc and 8 mm clearance between pair of stone disc showed the decortication efficiency of 76.87%.The developed chironji nut grader cum decorticator would help the cooperative farmers, tribal people, small help groups and unemployed youths for becoming an entrepreneur.
