FEEDING METHOD
w
CAUTION: Do not allow foreign materi-
al such as tools, hardware, stones, wood,
bottles or cans to enter the feed area. The
cutting parts will be damaged or destroyed
and the product contaminated.
A uniform, regulated flow of properly sized
product is essential to satisfactory operation of
the Model 1700. A meter calibrated to show
percent of full motor load is wired into the elec-
trical system. The optimum feed rate may or
may not be achieved at 100 percent motor
load. This will vary with the type and size of
reduction head and the product being run.
Once the feed rate has been established, with-
out overloading either motor or cutting parts,
the meter should be used as a reference.
The rate of discharge is as important as the
rate of feed. Product must not be allowed to
back up in the cutting enclosure. Ideally, prod-
uct should be discharged into an open receiv-
ing tank.
If a closed feed/discharge system is used, it
must be monitored carefully.
w
CAUTION: Any build-up of product or
pressure in the cutting enclosure could
result in serious damage to the spindle and
reduction head.
Except for an emergency, never start or stop
the machine when the impeller is full of prod-
uct. This puts a tremendous strain on the
motor, bearings and cutting parts. In addition,
product that is cut before the machine has
reached full operating speed may be of such
poor quality that it must be discarded.
SPEED CONTROL
The speed of the impeller is determined by the
motor pulley, spindle pulley and timing belt
used. Refer to page 74 for maintenance
instructions and to the drive chart on page 141
for the parts needed to operate at the required
speed.
