Modification of hand operated octagonal maize sheller
Improving Shelling Capacity of Octagonal Maize Sheller
Keywords:
Maize sheller, tubular, hand operated, maize, traditional shellingAbstract
TMaize shelling is one of the tedious and time-consuming agricultural operations. Shelling is the
important post-harvest activity in maize crop. The present study was undertaken to modify the
existing manual octagonal maize sheller (OMS) to increase its output capacity. The existing
octagonal maize sheller was modified and provided with a rotating handle and a clamp so that
it can easily be clamped with table, wooden rack etc. The performance of the modified
octagonal maize sheller was evaluated with manual octagonal maize shelling. There was an
increase in the average heart rate, energy expenditure as well as oxygen consumption while
shelling with the modified OMS, however, there was also an increase of output capacity by 32
per cent. The average output capacity of modified OMS was 18 kg/h as compared to 13.9 kg/h
with the existing octagonal maize sheller.
