AN OVERVIEW OF
INDUSTRIAL VACUUM
SOLUTIONS FOR FOOD
PRODUCTION
Let’s discover the three most common product lines used in
laboratories and companies to obtain production efficiency,
increase automation and maintain a high level of hygiene; all
according to ATEX certification and in compliance with GMP
standards.
INDUSTRIAL VACUUMS
Single-phase, three-phase and compressed
air. In stainless steel or completely painted.
Nilfisk industrial vacuums offer a high level
of filtration due to the polyester fabric
cartridge filters, ideal for very fine powders,
filtering air at high temperatures and for
toxic powders.
Nilfisk industrial vacuums are certified as
compliant with the following international
safety standards: ATEX, IECEx, CE, TüV
(L-M-H).
PNEUMATIC CONVEYORS
These are used to transport grains and
powders, according to precise preset times
and quantities, from the raw material
containers to the loading hoppers of the
packing or canning machines. They are
excellent for increasing the automation
of coffee and tea production lines. They
are necessary for maintaining quality of
mixtures in the beverage and confectionery
industry.
CENTRALIZED VACUUM SYSTEMS
When cleaning of surfaces over large
areas is required, or when access space
for mobile industrial vacuums is limited,
centralized vacuuming systems are the
perfect solution in the food industry.
They offer the advantage of positioning
the vacuuming unit, the filtering unit
and the exhaust system outside of the
production environment, maintaining only
the vacuuming hoses inside. Excellent for
continuously vacuuming in multiple points
along the conveyor belts.

OVEN CLEANING
NO MORE BURNED FLOUR OR CRUMBS = NO MORE EXPLOSION OR FIRE HAZARDS
The use of an industrial vacuum is excellent for cleaning inside an oven, such as an
industrial vacuum with a NOMEX filter (self-extinguishing material) suitable for vacuuming
white-hot substances. For all environments with a potential risk of explosion due to the
presence of flour, Nilfisk offers an ATEX certified industrial vacuum.
“… environments where there
is potential risk of explosion”
The ATEX certification of the
Nilfisk industrial vacuums,
for zone 21 or 22, makes it
possible to work safely even in
less ventilated environments
SAVING ENERGY AND TIME
WITHOUT LIMITS

EMPTYING AND CLEANING
THE DRIERS
EVEN THE MOST COMPLEX OPERATIONS BECOME SIMPLE AND FAST
Cereal driers are used increasingly due to continuous weather fluctuations and sporadic
rains which effect the quality of harvest or result in yields with unwanted moisture levels.
An easy and quick emptying of the driers makes a fast and more intensive rotation of the
drying phases possible.
“… faster and more
intense rotation”
Speeding up work means saving
time, but also a lot of energy
used for the drying process
ELIMINATING WASTE MEANS
PRESERVING PRODUCT QUALITY

[ f o o d ]
PRODUCTION LINE CLEANING
OCCASIONAL OR CONSTANT VACUUMING, ALL THE SOLUTIONS FOR A HIGH
QUALITY END PRODUCT
Keeping the production lines clean according to schedule prevents the product from being
contaminated by burnt crumbs and flour or other production waste. This operation also
avoids a high percentage of waste. The “TPlus” range is an excellent solution, for working
manually on the lines to serve this purpose.
The cleaning operation can also be performed as a continuous cycle by distributing
vacuuming points along the production line that are connected to a three-phase industrial
vacuum or a centralised vacuuming system.
“… avoids the product from
being contaminated…”
Product quality always results
from a strict control of its
contamination and avoids useless
waste that in turn requires
additional time for disposal

CLEANING MANUFACTURING
ENVIRONMENTS
A CLEAN ENVIRONMENT IS SAFE, HEALTHY AND EFFICIENT
The quality of the food production environment is the basis for guaranteeing hygiene and
safety. Nilfisk works constantly together with manufacturing companies in the design of
industrial vacuums and accessories dedicated to this purpose.
Cleaning the floors and production lines, as well as all of the systems, especially overhead
ones, are operations that Nilfisk mobile industrial vacuums help perform. Exceptional
quality of results are achieved, using accessories that speed up the work, only a few
minutes are required and the results can be seen immediately.
“… guarantee hygiene
and safety…”
Hygiene and safety make the
working environment more effective
because it can be fully utilized;
also creating an environment to
benefit operator efficiency

VACUUMING PACKAGING
MACHINE SCRAPS
THE DYNAMIC MANAGEMENT OF PACKAGING SCRAPS
IMPROVES PRODUCTION ORGANISATION
Nilfisk produces a range of industrial vacuums for the recovery of manufacturing scraps,
plastic, paper and fabric produced daily during the packaging cycle.
The industrial vacuum eliminates the continuous interruptions for cleaning the cutting
machine, avoids scattering the waste in the environment, whilst it makes it possible to
check product quality in real time, vacuuming any fine powder that can contaminate it.
“… checking product
quality in real time…”
The industrial vacuums can be used
to eliminate all contamination
risks, also during packaging
operations
MAXIMISING AUTOMATION IMPROVES
THE MANUFACTURING FLOW

TRANSPORT OF COFFEE
BEANS OR GRAINS
THE PNEUMATIC HANDLING OF COFFEE OR GRAINS MAKES IT POSSIBLE TO SAVE
TIME AND IMPROVE PRODUCT QUALITY
Nilfisk pneumatic conveyors are designed for transferring powders and grains that, taken
directly from bags, drums, big bags and other containers are released at a certain distance,
at the desired times and in the desired quantities.
Using pneumatic conveyors means being able to transport the product from a single point
to multiple destinations at the same time, and vice versa. The entire transfer process is
done hygienically, with respect for the environment and for the workers.
“… at the desired times and
in the desired quantities…”
Pneumatic handling not only avoids
harmful product contamination,
but also permits a perfect control of
the manufacturing flow, avoiding
expensive machine downtime

RECOVERY OF LIQUIDS AND WASTE
IN STORAGE AND AGEING SYSTEMS
HOW TO SPEED UP THE WASTE RECOVER TIMES
AND MAKE THE PRODUCTIVE ENVIRONMENT SAFER
Nilfisk produces industrial vacuums designed for cleaning in food storage and ageing
areas where it is necessary to vacuum liquids and solid organics and materials.
Essentially, there are three immediate advantages: saving cleaning time, making the
production and packaging environments more hygienic and lowering resource expenses
for maintenance.
“… less resource expenditure…”
Cleaning and the recovery of waste
can be carried out quickly and with
excellent results, which is the only way
possible to save time and money

ACCESSORIES
20
[ f o o d ]
The coloured nozzles with a rubber
lip are specifically designed for food
and drug environments. Available
in autoclavable and conductive
versions, they are FDA approved.
Coloured brushes
The coloured brushes, all with a
rubber structure (with the exception
of one in wood and aluminium) are
used for removing and vacuuming
dust from surfaces, machines,
production lines and structures in
a manufacturing environment.
Silicone hose
Antistatic non-toxic hose
The silicone hose is suitable for
cleaning powder from foodstuffs
and pharmaceutical mixtures (FDA
approved). It is white, resistant to
high temperatures (up to 200 °C)
and therefore can be sterilized in
an autoclave (at 121 °C). It has a
metal wire to earth the hose and
a stainless steel spiral; it is smooth
both on the inside and externally.
The antistatic non-toxic hose is
made of PVC with a transparent
polyurethane substrate, it is suitable
for cleaning abrasive and granular
materials. It is flexible and is
corrugated externally and smooth
on the inside. It also has a metal
spiral.
PTFE polyester filter
OPTIONAL
Nomex filter
The star-shaped or primary filter
is one of the most important
components in the vacuum cleaner
as it traps all the impurities that
could be pumped back into the
environment. These are in various
sizes to adapt to all vacuum cleaner
models, and in various materials.
Bag filters are used in the smallest
vacuum cleaners of the white line
series and in pneumatic conveyor
systems, they have a smaller filtering
surface area than star-shaped filters
and are used where a low quantity
of material must be vacuumed and
filtered.
Cartridge filter
Ideal for automatic and continuous
cleaning of the filtering cartridges
while vacuuming very fine or dry
powders.
The system “fires” jets of
compressed air inside the cartridges
while vacuuming, therefore it is not
necessary to turn off the vacuum
cleaner to clean the filter.
Separator for whitehot substances
Ideal for vacuuming and collecting
white-hot substances. The material
is cooled when it comes into
contact with the water in the
container. This water immersion
system may be suitable for certain
applications with dusty materials.
Separator for liquids
Ideal for vacuuming and collecting
liquids. A mechanical stop system
stops the vacuuming when
the container is full, whereas
the manual valves permit
the liquid to be drained.
Cap with mini-separator
Ideal for vacuuming light or dusty
material directly into the container.
It fits on the container or hopper,
creates a cyclonic effect which helps
deposit the material on the bottom.
Separator
Ideal for protecting the primary
filter from splashes of liquids
or potentially sharp material
vacuumed up. Should not be
used with dusty material.
Ciclone standard

[ f o o d ]
Grille and valve
Ideal for separating solid material
from liquids directly inside the
container. The grille in the base
of the container lets solid material
deposit, while liquids can be
recovered or drained through the
manual valve on the bottom.
Automatic liquid stop
Ideal for vacuuming liquids, and
powers down the vacuum cleaner
automatically. The unit powers
down when the max. liquid level
is reached in the container.
ARRESTO
Mechanical liquid stop
This stainless steel system stops the
vacuum system mechanically when
the max. liquid level is reached
in the container. Mainly used on
compressed air models or where
automatic stop is not envisaged.
STOP
Paper bag, safe bag and
anti-static safe bag
The container, which can be
exchanged with the original, is
able to house the paper bag or
safe bag. The safe bag system can
be used to collect toxic powders
and has a safety closing system
that upon its removal prevents
the user from coming into contact
with the vacuumed product.
