The kernel contains the nuts of chironji. Traditionally, it was removed by hand hammer, small stone or some locally available stone chakki (Jatta). These methods are very tedious, laborious and uneconomical to the farmers and result in low quality products with higher broken kernels. To overcome this problem in processing of nut, IGKV, Raipur, design and developed a chironji nut decorticator, to remove outer shell from the nuts to get whole kernels. The machine comprises of feed hopper, cylindrical housing, decortications unit, main frame, electric motor, grader, sieve etc. Results showed that the efficiency of machine was found to be 93.90 % and capacity was 32.82 kg/h. The whole kernels and broken percentage was obtained at 16% and 2%, respectively. The machine is most useful to the small farmers, small entrepreneurs, self help group, tribal group etc. who are involved in decortications of chironji nut. In this method the cost of operation and time required to decorticate is very less as compared to traditional method.
