Not AvailableIn tribal areas of India, traditional methods of threshing of minor millets like little millet (Panicum sumatrense),
M1, kodo millet (Paspalum scrobiculatum), M2, foxtail millet (Setaria italica), M3, proso millet (P. miliaceum),
M4, barnyard millet (Echinochloa frumantacea), M5, finger millet (Eleusine coracana), M6 is done of beating by sticks
or treading out the crop panicle under the feet of oxen. This operation is most time consuming, labour intensive,
drudgery prone, uneconomical, lower output and obtain low quality products. A thresher for these millet crops was
developed and optimization of the operating parameters with little millet was done by using Response surface methodology
(RSM). The optimized parameters were 7.79% (d.b) moisture content, 105 kgh-1 feed rate, 625 rpm cylinder
speed, 5 mm threshing sieve size which gave maximum threshing efficiency of 95.13% and cleaning efficiency of
94.12%. After optimization of parameters the thresher was tested for threshing of all the six minor millets with proper
adjustments of sieve. Threshing capacity of M1, M2, M3, M4, M5 and M6 were obtained as 89, 137, 140, 91, 88 and 99
kg/h, respectively with more than 96% threshing efficiency and less than 2% broken grain.Not Availabl
