Choosing The Right Equipment
For Safe Food Manufacturing
As food manufacturers know, regulations have made us all think differently
about food safety issues. Industry is
driving standards by plant zones to
ensure producers are using the right
product for the right application.
The first zone of a food
processing facility (Food Zone,
High Hygiene or IP69 area) is the
most critical area. Equipment is
vulnerable to contamination due to
direct contact with food. In the Food
Zone, equipment is sanitized with high pressure spray at various
angles from up to six inches away at temperatures as high as
176° Fahrenheit. What’s important here is not to under-specify
your equipment, because using the wrong equipment could result
in an inspection failure, plant shutdown or fine. When specifying
equipment, look for features that reduce contamination and water
ingress, including superior sealing systems, stainless steel, H1
food grade oil, laser-etched nameplates, encapsulated windings
and IP69 ratings for water.
In the second zone (Splash Zone, Medium Hygiene), equipment
doesn’t directly contact food, but liquids from processing or
cleaning may splash on the components. In this area, standard
seals are adequate and seal covers are appropriate. Look
for breathers which prevent water ingress and desiccants to
eliminate humidity concerns. Standard mineral or synthetic oil
is sufficient, and epoxy-painted finishes keep everything looking
sanitary. In addition, motor enclosures may include neoprene
gaskets and condensation drains which can withstand some
splashing or light washdown.
The third zone (Non-Food, Low Hygiene) is an area where
products are not susceptible to contamination. As a dry area,
there’s no need to over-specify your equipment. Products referred
to as general purpose or general use are sufficient and, in most
instances, do not require special sealing. Expect standard paint
and standard mineral or synthetic oil; for motors, open drip proof
or totally enclosed designs are generally acceptable.
Manufacturers provide a variety of equipment options for both
wet and dry areas of a food processing facility. Selecting the right
ones are necessary to keep your production facility running safely,
efficiently and cost-effectively.
ABB Motors and Mechanical Inc.
WeighPack Systems, Inc.
introduces the C- 10 to
its PrimoLinear family
of automatic linear net-weigh filling equipment,
for limp, non-free flowing
and delicate products.
The C- 10 utilizes a
system of motor-operated
conveyor belts to gently
transfer food product
from the hopper to the
10-liter pneumatically-actuated weigh bucket
that it employs to
dispense product into
various package types. The PrimoLinear C- 10 system can be
customized for semi-automatic or fully automatic dispensing
cycles with single-lane or dual-lane functionality, dependent
upon the performance speed required. To the benefit of today’s
food producers, the PrimoLinear C- 10 is designed with an open
frame leaving no small crevices for bacteria to develop and
drastically reduces cleaning time between production runs.

Variable Intensity Blender
Munson Machinery has introduced a variable intensity blender
(model VIM-124-SS) with six injection ports, allowing liquids in
small to large volumes to be combined with bulk food materials
to produce pastes and slurries continuously at high rates.
Constructed of stainless steel, the sanitary unit can achieve
homogenous blends in as little as 20 seconds residence time
depending on material characteristics, yielding up to 200 cubic
feet of throughput per hour. A large-diameter solid main shaft
rotating within the cylindrical vessel is supported by externally
mounted bearings with air-purged seals. Large radius welds
connecting paddle arms to the shaft permit rapid cleaning and
sanitizing. The agitator is driven by a 20 HP ( 15 k W) explosion-proof inverter-duty motor with enclosed gear reducer and
variable frequency drive that can rotate the agitator at speeds
from 600 down to 120 RPM with no overheating.
