Abstract:
Most of the millet crops are native of India and are a group of small grained cereal food crops which are highly nutritious. Millets are popularly known as nutri-cereals as they provide most of the nutrients. Value addition in millets has great potential in increasing the profitability in cultivation. In this work, the performance evaluation of destoner cum grade cum aspirator (pre cleaner), double stage dehuller, rice separator (post cleaner), Polisher were studied. The machine capacity, cleaning efficiency, dehulling efficiency, whole rice recovery and broken rice recovery were recorded. The capacity of destoner cum grader cum aspirator (Pre cleaner) was recorded as 220.85, 212.52, 214.04 and 210.32 kg/h in case of foxtail, browntop, little and barnyard millets respectively. The capacity of double stage dehuller was recorded as 108.82, 103.75, 108.46 and 104.57 kg/h in case of foxtail, browntop, little and barnyard millets respectively. The capacity of rice separator (Post cleaner) was recorded as 223.52, 210.66, 211.75 and 204.48 kg/h in case of foxtail, browntop, little and barnyard millets respectively. The capacity of grain polisher was 40 kg/h for all the minor millets under this study. These machines are good to process all minor millets and they can be procured by small and medium scale processing industries to process the raw minor millets.
