OPERATING PRINCIPLE
Product is guided to the center of a high
speed, rotating impeller (Figure 10). Centrifu-
gal force moves product outward to the im-
peller tips, which carry the product past the cut-
ting edges of the stationary reduction head.
Size reduction is accomplished by actually cut-
ting the product as opposed to hammering or
tearing.
Cutting heads and microcut heads are the
most widely used types of reduction heads on
the Model 1700 (a slicing head is also avail-
able). See the following pages for more specif-
ic information on each type of reduction head.
OPERATING SPEEDS
For optimum cutting results, different prod-
ucts may require a change in impeller speed
(see chart).Impeller speed is altered by chang-
ing the spindle pulley, motor pulley and timing
belt. See “Motor and Drive Parts”, page 140.
w
CAUTION:
Never operate three inch
impellers at speeds greater than 6480
RPM; to do so could damage or destroy the
cutting parts and contaminate the product.
FEED ASSEMBLIES
Feed assemblies consist of the impeller and
the parts necessary to direct and contain prod-
uct to the cutting area.The feed assembly used
will be determined by the nature and size of the
product to be cut. Specific parts that are com-
patible with the reduction head and impeller
are required for each feed assembly. Conse-
quently, some parts are not interchangeable
between different feed assemblies. See pages
90–108 for the feed assemblies available on
the Model 1700.
