Millets with great health benefits, small nutritious grains are growing worldwide for food and feed. Due to the typical structure, hardness and small size of the shell grains, millet threshing remains a constraint. This study deals with the performance evaluation of the developed low-cost tabletop centrifugal threshing machine. Threshing experiments were performed on five millets at three moisture contents (11.1, 13.6 and 16.2% db) and three peeling rates (6000, 5,500, and 6000 rpm), namely foxtail millet, little millet, millet, kodomillet and barnyardgrass. The water content of the grains had a significant effect on threshing performance compared to the threshing rate, which had a lesser or negligible effect on time. The highest average threshing efficiencies obtained for millet, little millet, and millet were 92.7, 91, and 93.5%, respectively, at a grain water content of 13.6% (db) and a threshing rate of 5,500 rpm. The highest average threshing efficiencies for barnyardgrass and barnyardgrass were 80.9% and 74.4% at 11.1% (db) water content and threshing rate of 6000 rpm, respectively. For the same experimental combination, the rate of destruction was less than 5% for millet, little millet, and millet, but 5.7 and 9.2% for codomillet and barnyardgrass, respectively. The average threshing shell grain ratios to foxtail millet, little millet, millet, codomillet and barnyardgrass were 2.4,5.7,2.3,14.2 and 18.1%. The approximate cost of converting 1 kg of millet to rice is INR 0.97 ($ 0.01). (Translation author abstract)
Nigeria is known for its annual production of over 265,000 tonnes / year of palm. Palm dehulling has been done manually using machete. Due to the difficulties involved in manual palm dehulling, it is necessary to mechanize the work by developing an indigenous palm shell peeling machine. This machine consists of spikes, chain drive, gears, electric motors, bearings, shafts, reduction gears and sprockets. The machines performed best with local varieties of palm with an average water content of 5.08% (db), giving average mechanical capacity and percentage throughput of 175 coconuts / h and 84%, respectively.
