ABSTRACT: The purpose of this
research is to improve the performance of the tool
before and get a corn sheller
sheller corresponding cylindrical shape. The modified part was the cylinder of
sheller by using 4, 8, and 12 segments of serrations. Each cylinder received 3
treatments. The cylinder was fed by 1 cob (T1), 2 cobs (T2), and 3 cobs (T3) with
three replications. This research was successful to modify the corn sheller
machine with dimension of 100 cm x 50 cm x 115 cm with three types of sheller
cylinders. The mechanism principle of this corn sheller was that the sheller
cylinder in the middle of holder cylinder was operated by human power through
hand crank with 50 to 70 rpm. The results showed that the highest yield (96%)
was obtained by corn sheller with 4 serrations while 4% remained unshelled. The
lowest yield (92%) was obtained by corn sheller with 12 serrations while 8%
remained unshelled. From all treatments, the
best result was corns sheller with 4
serrations fed with 3 corn cobs with percentage of 99.40% good shelled
weight and 0.60% poor shelled. The lowest result with biggest damage was in the
corn sheller with 8 serrations fed with 1 corn cob. The result was 97.53% good
shelled and 2.47% poor shelled. The highest capacity (1.58 kg corn cobs/minute)
was obtained by the corn sheller machine with 4 serrations.
