The frame was constructed from angle iron with
joints welded together with gauge 12 electrodes for
rigidity. The frame configuration is such that it
supports the hopper, the blower and suspends the
sieve assembly as well as the drive unit. Plates 1 and
2 shows the front and the oblique view of the cereal
cleaner respectively. The hopper has a capacity of
3.55 x 10-2 m3. It is made of flat sheet folded into a
rectangular prism, tapering down at the base. The top
of the hopper measures 50 cm by 50 cm. A slide gate
mechanism was used for metering of grains into the
sieve assembly.
