Separation
Preparation pan
The preparation pan is the first part of the cleaning system that the grain will come into
contact with. It’s function is to separate the grain and the chaff. The grain is heavier and
therefore goes to the bottom, the lighter chaff goes to the top. It is important that this
is kept clean, to allow this to happen effectively. A dirty preparation pan will cause a
poor sample and reduce output.
Fan
The speed is shown on the CEBIS screen. The
speed range of the fan is 680rpm – 1600rpm.
Adjustments are recommended at no more
than 50rpm at a time. On all LEXION 600’s and
LEXION 760 only, the position of the flaps in the
ducting from the fan can be adjusted with the
use of the pre-separation wind duct lever. The
more grain on the sieves, the further back the
lever needs to be. With high outputs in wheat it
is not uncommon to use hole 7.
