Rolls:
The Model 4240 Clod Hopper is designed with 4
rolls to clean the small, large and debris stream of
product. After the sizing table separates the flow
of potatoes into the large and small sizes, each
one is directed over a set of rolls to remove clods,
stones and debris. The resulting debris stream
also goes over another roll to remove the remain-
ing potatoes. The large and small streams go over
the primary rolls and the debris stream goes over
the secondary roll.
Each roll can be moved relative to the end of its
conveyor using the handle on one end of the
frame. Each handle is connected to the adjuster
on the other side of the frame through a threaded
rod. Start with the "M" setting and adjust as re-
quired. Be sure to direct the stream of potatoes
to impact the roll at the 10:00 to 10:30 position for
best results.
