Crop
Function description
1. Inlet of uncleaned crop
2. The inner screen separates large
impurities from the crop
3. The outer screen separates small
impurities and kernels from the crop
4. The impurities from both screens
are collected in the bottom through,
where the auger will convey the
impurities towards the inlet end
5. The impurities are guided into the
injector on the blower tubing (if both
shutters are closed)
6. The blower sucks air and light impu-
The capacity of the cleaner de-
pends of settings and screen se-
lection:
• If the cleaner's inclination is in-
creased, the crop flows faster
over the screens. Capacity is
increased and purity is reduced.

12. Outlet for large impurities from
the inner screen
13. Outlet for small kernels and
impurities from the outer screen

• Internal screens with small
holes increases the cleaning
efficiency and reduces the
capacity.
