CONVEYING
J-Tec designs, supplies, installs and
maintains systems for handling
dry substances and liquids. We
supply everything from individual
components to complete turnkey
installations. Our main fields of
activity are the food industry,

continually intest in state-of-the-art
facilities, equipment and ICT systems
worldwide. However, it is thanks to
the initiative, enthusiasm and skills
of our people that we are able to
offer a better, more efficient and
cost-effective total concept to our
customers.
Pneumatic conveying
Pneumatic conveying is a means of conveying
dry powders and other solids in an enclosed
system using air pressure as the means of con-
veyance.
Dense phase conveyingTwo variations of pneumatic conveying are
dilute phase and dense phase conveying.
Dilute phase conveying is characterized by a
high volume of air, lower air pressure and low
volume of solids per unit air volume while dense
phase is characterized by lower air volumes
and higher pressures and high volumes of solids
per unit air volume.
Dense phase conveying takes place at rela-
tively lower velocities and higher mass load
ratios compared to the dilute phase.
ApplicationDense phase conveying will typically be cho-
sen for:
• abrasive and sensitive products
• powders and pellets
• higher capacities
• long distance conveying (overpressure
dense phase)
We can make a distinction between vacuum
dense phase and overpressure dense phase.
Advantages
• avoidance of product damage
• avoidance of segregation of mixtures
• reduction of the wear of the complete
systems when conveying abrasive
products
• Higher conveying capacities due to typi-
cally high mass loading

Vacuum dense phase
Vacuum dense phase systems are par-
ticularly suitable for systems, which convey
materials at high capacities over short to
medium distances (up to 100 m), from
multiple sources to a single destination.
Using vacuum pumps, moving plugs of
material are formed and conveyed at sub-
atmospheric pressures.
Overpressure dense phase
In an overpressure dense phase system
the working pressure of the conveying air
is 2 bar or higher. The conveying air will
either be delivered by a compressor or
supplied by the distribution pressure net-
work at approximately 6 bar.
Depending on the technique and the
components used, we distinguish the fol-
lowing variaties of overpressure dense
phase pneumatic conveying
A Continuous dense phase overpres-
sure conveying with rotary valve
B Discontinuous overpressure convey-
ing with 1 (or 2) pressure vessel(s)
In both continuous and discontinuous
conveying systems we distnguish:
1 Unit for compressed air supply
2 Air regulating unit
3 Product feed into conveying tube by
rotary valve or by pressure vessel
4 Conveying into reception vessel

Options
Tandem pressure vessels:
For continuous feeding of the recep-
tion vessel and much higher capaci-
ties, a continuous conveying system
will be selected by means of a pres-
sure vessel. In this case the two ves-
sels alternatingly send product into the
conveying system.

Dilute phase versus dense phase
Among the various types of pneumatic con-
veying we distinguish the dense phase from
the dilute phase based on different charac-
teristics.
Dense phase conveying runs at relatively lower
velocities and higher mass load ratios com-
pared to the dilute phase.
The working pressure of the conveying air will
be 2 bar or even higher. Therefore the con-
veying air will be delivered by a compressor
or supplied by the distribution pressure network
over the plant at approximately 6 bar.

Application of dilute phase conveying
A dilute phase conveying will be chosen in
typical cases such as:
• Distances up to 100 m (vacuum) - 200
m (overpressure)
• Limited capacities
• No special requirements towards prod-
uct degradation
• No special requirements towards dust
formation and segregation
Structure of dilute phase conveying
Depending on the technique and the
components used, we can distinguish
between two types of dilute phase
pneumatic conveying:
A. Continuous dilute phase conveying
B. Discontinuous dilute phase conveying
In both continuous and discontinuous
conveying systems we distinguish overpressure
and underpressure.

Screw conveyor
This screw conveyor is custom-made to
meet your demands, but it is built with
standard components. The end result will
meet your requirements.
The food industry and fine chemicals
branch have high demands regarding
hygiene for conveying systems. To meet
these demands screw conveyors have to
be easy to clean.
To this effect, the screw conveyor can
be equipped with hinges and fasteners,
making it possible to completely remove
the cover.
Obviously, we have to keep safety in mind.
Therefore the covers are equipped with
safety switches, compliant with safety norms.
The screw is completely welded on two sides
by a welding robot. This guarantees uniform
welding, meeting high quality demands.
Vertical screw conveyor
This screw conveyor is specifically designed
for transporting powders and pellets in
vertical direction. No more dangerous and
difficult carrying of bags onto ladders and
platforms.
The vertical screw conveyor transports
material dust-tight to the right place. You
decide the height of the conveyor and the
desired content of the shoot. Tailor-made at
your request.
Safety, quick dismantling for cleaning and
other features are accounted for.
In many business industries such as food
and chemistry, pharmaceutical and plastic
industry, this vertical screw conveyor offers
the perfect solution.

High pressure air supply unit
For high pressure transports with air lock, J-Tec
has developed a special air regulating unit,
which can be used for the compressed air
net as well as for a screw compressor.
This air regulating unit consists of a completely
adjustable air valve combined with a flow-
meter.
For extremely low conveying velocities these
transports can be combined with side injec-
tion (bypass).

CONVEYINGAir supply unit & Pressure vessel
Pressure vessel
Through ongoing improvement of the product
inlet system and further development of the air
regulation unit, we were able to accomplish:
• a system fit for both fine and coarse
abrasive granular materials
• putting an end to plugging of the con-
veying piping
• an even product flow at the end of the
conveying line
Apart from dense phase systems, our program
also contains dilute phase conveying systems.
