The
heart of the hulling process is the twin, rugged 18"
dia rolls equipped with removable huller knives. These
twin rolls are driven at a ratio to enhance the cutting
process thus minimizing the amount of uncut and recycle
seed. This ratio combined with a spiral lead on the
cutting edges allows the highest percentage of open
"hulled" seed available to the separation
room.
The replaceable huller knives are manufactured from
the highest quality alloy and hardened to 52R for extra
long process life. Having removable hulling surfaces
allows Cottor to tailor the knife profiles to fit the
specific hulling requirements of the wide variety of
oil seeds processed. All huller knives are manufactured
from a single fixture giving absolute interchangeability
for all replacements. |
