Final
Design
The figures below portray our final design for the device. A description of
the process can be found below the figure:
1. The harvested heads of amaranth are fed into the thresher which uses a grooved, frictioned belt to thresh the amaranth heads. 2. The threshed debris falls onto a screen, which stops any large material, such as stems. 3. The seed, chaff, and dirt fall through the screen into the chute. 4. Here, the seed, chaff and dirt mixture encounters an air flow generated by the fan. This air flow is at a speed which allows the seed to fall, but blows the chaff out the chute. 5. Finally, the seed, at the bottom of the chute, falls through a small slit into a catch pan. |
