SAFETY STRATEGIES
In a truly sanitary conveyor, personnel have complete and easy access to all
areas of the system for cleaning.
sanitary conveyors can be
seen in their non-plate-onplate construction. Frame
sections in plate-on-plate
designs are often bolted
together with fasteners-
notorious harbor points for
contamination. This type of construction, in turn, prevents users from disassembling the equipment for cleaning.
In a truly sanitary conveyor, fasteners
are removed from the food zone and
replaced with non-harbor-point welds,
where necessary.
Different levels of 'sanitary'
VFD-Driven Motors Are at Risk
of Bearing Damage!
VFDs induce voltages on the shafts of
the motors they control - voltages
that can discharge through bearings,
destroying them in as little as 3 months!
Test Motors for Shaft Voltages
The new AEGIS® Shaft Voltage Tester™ Digital
Oscilloscope is configured to measure shaft
voltages right out of the box. This 100 MHz dual
channel oscilloscope comes with everything you
need to take and capture shaft voltage readings
in high-resolution, including a 10:1 probe with
special microfiber tips, a probe holder with a
magnetic base, and a compact carrying case. With
the push of just one button, the scope's screen
capture feature saves images for
analysis and reporting.

Protect Motors with the
Most Effective Shaft Grounding
Don't settle for conventional bearing protection
products that wear out quickly, require frequent
cleaning or adjustment, or have limited currentcarrying capacity. Proven in more than 2 million
installations worldwide, AEGIS® Shaft Grounding
Rings are maintenance-free and last for the L-10
life of the motor bearings.

When researching sanitary-conveyor
platforms, Kuhnz said, it's important to
consider where in a plant the equipment is to be located. For example, in
more downstream-oriented processing
applications, i.e., where sealed and
packaged food items are being moved,
a conveyor might not need to be as
hygienic as a system that carries raw
food and ingredients.
Although downstream conveyors
often accumulate corrugated dust from
the cardboard packaging, washing or
simply wiping them down constitutes
adequate cleaning. These systems are
still classified as sanitary designs, but
the more robust sanitary platform isn't
typically required.
The crux of the matter
Keep in mind that just because a
conveyor is built of stainless steel doesn't
mean that it is engineered with proper
hygienic attributes. This, according to
Kuhnz, is really what is at the crux of
the whole sanitary vs. stainless-steel
comparison.
His point is that more thought, from
an engineering standpoint, goes into the
sanitary conveyor to make it a truly a
hygienic platform. The sanitary aspects
are considered upfront during the
design phase to ensure these conveyors
are more available and productive in
food-processing facilities than systems
that aren't truly sanitary. For companies
involved in these types of operations,
understanding the different levels of
"sanitary" in today's conveyors will go
a long way toward providing peace of
mind. MT
