| Description |
In India, Maize (Zea mays) is an important crop after the rice and wheat. Many farmers grow maize but could not afford the cost of acquiring some of the imported threshing machines because of their cost. Such people resort to manual means of threshing which results into low efficiency, high level of wastage and exerting of much labor. This machine was constructed to shell maize and separate the cob from the grains. It was constructed from locally available materials and its cost is low and affordable. The operating speed of pedal operated maize sheller was optimized for its operation at higher operating speeds in pedaling mode. Effect of operational parameters of pedal operated maize sheller i.e. shelling disc r.p.m. (80, 130, 150, 230 and 280) and moisture content (7, 9, 11, 13 and 15%) of maize on machine capacity (kg/h), unshelled grain (%), mechanically damaged grain (%), shelling efficiency (%) and cleaned outlet grain (%) were studied. The capacity of machine was maximum 56.71 kg/h with maximum shelling efficiency and cleaned outlet grain i.e. 99.25 (%) and 98.45 (%) respectively and minimum mechanically damaged i.e. 3.88 % at shelling disc r.p.m (180 r.p.m) and moisture content of maize was 9 %. After the optimization of operational parameters of the machine using RSM, the results were found that capacity of machine and shelling efficiency were maximum i.e. 65.92 and 99.60 % respectively and mechanically damage was minimum i.e. 4.77 % at 216.4 shelling disc r.p.m and 8.17 % moisture content of maize. |
