OPERATING PRINCIPLE
Product is delivered by an agitator and
feed screw to the cutting head and impeller
(Figure 12). Once in the stationary cutting
head, the heart of the Comitrol unit, product
is revolved by the rotating impeller at high
speed with the resultant centrifugal force
propelling the product outward (Figure 13).
The impeller tips force the product against
uniformly spaced horizontal separators. Small
portions of product projecting into the spaces
between the separators are cut off into parti-
cles by spaced columns of vertical knives.
These particles fly outward and away from
the cutting head. The wall surfaces between
the vertical knives are relieved to eliminate
friction that would produce heat. Motor power
is effectively utilized to cleanly sever the
product into uniform particles instead of pro-
ducing destructive heat. For a description and
list of the cutting heads available, see
“Cutting Heads”, pages 64 & 66. Impellers
are listed on page 63. Consult the factory for
specific cutting head and impeller application.
