The principle of vacuum conveying
1. Components of a conveyor system
The minimum configuration of a complete conveyor system consists of atleast one product intake, one transport line and the actual vacuum conveyor
with its control system. A feed station or a conveyor gun is used as the product intake depending on whether the material to be transported is locatedin a silo, a Big-Bag station, a barrel or a different type of container. It is thelink to the transport line and supplies additional air to the material under the
influence of the vacuum (false air). This creates a material/air mixture, which
is now transported through the transport line to the conveyor unimpeded. A
pipeline or a vacuum-tight hose is used as the transport line.

Product intake

Once the transported material has reached the vacuum conveyor, filters
separate the air from the material/air mixture and it collects in the collection tank on the conveyor‘s bottom valve. Once the desiredquantity of material has collected in the conveyor over theset vacuum time, the control system shuts down the vacuum supply and opens the bottom valve.

2. Function of a vacuum conveyor
While the bottom valve is closed, the vacuum pumps generate a vacuum inthe housing. The material to be transported is sucked in through the pipeline
and collects in the collection tank on the closed bottom valve. During thisprocess, swirling material adheres to one or more filters in the top sectionof the housing. At the same time, overpressure is generated in the AirShocktanks, which are each connected to a filter.

The vacuum pump switches off once the set transport time expires. The bottom valve opens and the transported material is discharged down and outof the tank. At the same time, the filters are back-flushed via the stowed
compressed air from the AirShock tanks. The bottom valve then closes andthe process can start again. The process continues in a set rhythm, without
restriction, depending on the setting.

3. Modular design of our vacuum conveyors

A

Our standard models can be viewed as the basic equipment for different,
typical applications and transport quantities. In practice, almost all conveyor
systems that we deliver are individually customised to deal with specificrequirements. This means that a different number and length of module segments and filters as well as vacuum pumps in various output classes areused. The function of the circuit and control unit is also adapted to yourspecific process conditions.

B
C

Despite this, our conveyors remain extremely flexible. Every segment canbe adapted to changing production conditions or replaced if it is damaged.

D

We also provide housing made from different types of stainless steel andwith different surface treatment as well as different filter types and gaskets.
This depends on the chemical properties of the transported material as well
as safety and environmental and hygiene requirements. It also enables thetransportation of toxic substances or materials that represent an explosion
hazard. It simply depends on whether screws, sand, magnesium or cereal
grains are being transported.

close in succession. If the resistance decreases, e.g. because more false air issucked in, the flap valves open automatically.
A self-regulating system.

The core of the vacuum pump primarily consists of horizontally arranged
chambers. The first chamber (pressure chamber) is always filled with compressed air. Openings with air nozzles are located between the chamber
partitions. These are always in the same position (height and depth) so that astrong airflow can effectively flow through all the nozzles from the pressurechamber unimpeded.
This strong airflow, with its air molecules, pulls additional air molecules
through the nozzles, resulting in a vacuum in these chambers. The volume
of air discharged from the vacuum pump is now significantly greater than
the supplied compressed air, but has lower pressure. This energy has been
converted to a vacuum in the vacuum chambers and is able to transportlarge quantities of material over long pipelines into the conveyor‘s housing.
All flap valves are opened when initially establishing a vacuum. As the vacuum increases, due to the product resistance in the system. the flap valves

5. Filters for vacuum conveyor systems
The filters in a vacuum conveyor separate the air from the material/air mixture that arrives in the conveyor. The filter stage may consist of a single filter
or multiple filter elements and performs several tasks. It ensures that noparticles reach the vacuum pumps, that the production facility’s ambient air
is not contaminated and, in the case of powdery material, that the material
loss remains as low as possible.

We distinguish between tight and open folds. Tight folds have a larger area
due to the higher number of folds and can therefore retain more particles.
But, they have a disadvantage when dealing with adhesive or sticky transport materials. After back-flushing via the AirShock tanks, particles remain in
the tight folds, which has a negative impact on performance. In these cases,
filters with open folds are used.

Depending on the purpose, we provide filters in different sizes and designs
as well as with different filter materials and other special design features.
The right selection depends on the conveyor’s output, the properties of thetransported material and various other aspects, such as safety and environmental protection.

Filter material:
Three different filter materials are primarily used. Woven stainless steel isideal for coarse-grained transported material, but fine particles would penetrate into the filter fabric. As a result, absolute filters are used in thesecases. The have a Teflon coating. The particles adhere to the surface and areeasy to backflush. For example, Teflon-coated polyester is suitable for paintpigments as well as for extremely fine powders. If the material has a coarser
grain, such as sand or granules, aluminium-coated polyester provides bettertransportation and separation. Depending on the transported material, thedensity of the fabric also plays an important role to ensure the optimal efficiency of the conveyor system.

Design:If the system is designed for a low transport capacity, cylindrical filters areused. For higher transport capacities and fine particles or adhesive powders,candle-shaped filters are generally used. If working with strong vacuums,
e.g. for long transport lines, reinforced filters are the right choice. This typeof differential pressure-reinforced filter has a perforated stainless steel tube
in its interior that supports the filter fabric. This provides additional stability
and tear-resistance.
A special design variation is the filter with folds that open at the bottom. In
this case, the lower end of the filter is not closed by a cap, but by an adheredplug, which is located inside the filter sleeve. This facilitates the access of theair/material mixture and back-flushing, which is particularly beneficial foradhesive and oily materials.

vacuum resistanceLeft: Folds that open at the bottom
Right: Standard end cap

Which filter material is best suited for the specific application depends verymuch on the process.

The principle of vacuum conveying

6. AirShock tanks
A valve charges the integrated AirShock tanks with compressed air whilethe vacuum conveyor is in operation. These AirShock tanks are discharged
automatically once the vacuum pump stops. A special system creates a
shockwave under every AirShock tank, which effectively cleans the filters.

7. Product inlet
Besides our standard configuration with tangential inlet, there is also theoption of using a radial inlet with non-return valve. This primarily prevents
excessive dust backflow in the transport line.
The inlet creates a vortex in the conveyor’s collection tank, reducing thestrain on the filter. In particular, it is ideal for materials with small
particle sizes, such as powders, pigments and flour.
The radial product inlet may be more appropriate for coarser
and sharp-edged transported material in some circumstances. It
reduces wear on the inner side of the housing. The radial inlet
counters unwanted adhesion inside the housing if oil and moist
materials are transported.

8. Bottom valve with free-flow valve
technology
An important feature of all our Lutena vacuum conveyors is the free-flow
valve technology. The bottom valve effectively opens across the entire housing diameter. This ensures an extremely quick and reliable product discharge.
It means that bridge formation in the housing is impossible and additional
installations, such as fluidisation, beaters and vibrators are not required.
Often copied – never replicated.

9. Product intake
The material to be transported can be fed into the conveyor system fromvarious containers. We therefore provide two different processes for feeding
the material into the conveyor system. A conveyor pipe removes the material
to be transported from above, e.g. from sacks, barrels, tanks or cartons. Thisis a manual type of product extraction.
We recommend using a feed adapter to enable an automatic product intake.
This can be mounted under various existing systems.
It may be a silo, a big-bag station or even a feed station into which thematerial is poured.

Conveyor pipe:
The conveyor gun, which sucks in the material from above, may also consistof an outer and inner pipe. In contrast to a feed adapter, with its horizontal
injector, in this case the material/air mixture is supplied to the conveyor line
through the inner pipe. The outer pipe is used to supply false air. The mixture of material and air takes place at the tip of the conveyor gun, which isinserted into the material or bulk to be transported. The bulk material phase
can also be adjusted by adjusting the inner pipe. The conveyor pipe can bemounted to a piece of equipment or can be held by hand. Bridge formation
inside the housing is not possible and additional installations such as fluidisation, beaters and vibrators are not required.

Feed adapter:
The inlet funnel of the feed adapter is directly connected to the silo or a feedstation via a flange or a clamping ring. The material flows through this inlet
into the underlying horizontal intake pipe, where it gathers as a plug. A small
pipe with a narrow diameter is located inside this pipe, which penetrates
through the material plug. This is a horizontal injector, which is connected tothe intake pipe via a bushing. The vacuum suction now conveys the external
air through the injector and also carries along particles of the transported
material as a material/air mixture. The inflow air is controlled by a ball valve
and the position of the pipe end from the injector allows the conveyor phase
to be adjusted. If a large volume of air is added, this is referred to as the flow
phase, which means that the material/air mixture is conducted through theconveyor line at high speed. In a dense phase, more material is transportedwith less air, but more vacuum power is required to prevent blockages inthe transport line.

Addition of false air
using a double-walled system

The specific conveying phase, i.e. the air to transported material ratio, thatprovides the optimum transport performance depends on the material.
A second false air adjustment option with ball valve adds more air (falseair) along the path behind the horizontal injector and provides additional
acceleration for the material flow. Air filters can be attached in front of bothball valves in order to prevent the contamination of the transported material,as they generally take in ambient air close to the ground.

The principle of vacuum conveying

10. Transport lines
Pipelines or vacuum-tight hoses with embedded steel spirals are used totransport the material between the product intake and the vacuum conveyor. Combinations are also possible. In general, for longer lines, conveyor
systems with stainless steel pipelines are more efficient and faster, as theygenerate less frictional resistance. They are the best choice for stationary
systems.

The transportation of coarse and sharp-edged materials or
objects at high speed may damage the inside of the vacuum
conveyor and its filters. In these cases, special pipes with increasing diameters are used, which reduce the speed of thetransported material before it reaches the conveyor. Special
inlet modules are also possible.

Transparent conveying hoses are generally used for distances up to 20m.
They have the benefit of simpler and faster assembly and also give the operator the opportunity to see what is happening in the transport line. Potential
blockages are easier to localise.

A specific ratio exists between the pipe diameter and thequantity. For example, a pipe with a diameter of 100 mm cantransport twice the amount of a pipe with a diameter of 75
mm.

In both cases, the longer the line and the more vertical the line elements, thelower the output of the entire conveyor system. Using the latest state-ofthe-art technology, the maximum transport length amounts to about 100 m.

Pipe bends:
Pipe bends also reduce transport performance. The deflectionof the material/air mixture from its straight direction of flow
leads to additional frictional resistance in pipe bends. The
smaller the radius of the pipe bend, the greater the friction
loss. For example, a pipe bend with a radius of 90 degrees generates precisely the same amount of resistance as a 2m-long,straight line with the same diameter. (A bending radius of
R=10xD must be ensured)

Dimensions:
Besides the capacity of the vacuum conveyor, the diameter of the transportline also plays an important role. A narrow diameter results in a higher transport speed and can increase the transport volume for materials in dense
phase conveying. If the line has a larger diameter, the material transport isslower, but the susceptibility to blockages is lower. It therefore depends on
the right combination of power and line cross-section based on the transported material.

An overview of the behaviour of different pipe dimensions:

Ø 100 = 1 Lines
Ø 75 = 2 Lines
Ø 50 = 4 LinesØ 32 = 8 Lines

Another aspect is wear. This is particularly prevalent when conveying large and sharp-edge transport material. In this case,the use of hoses is preferred. Particles of the transported material may become embedded in the bend area of the hose,creating wear protection. A improvement in the service life
by a factor of 10 compared to stainless steel pipe elbows
is not unheard of.

11. Product discharge / transition pieces
In completely closed systems, the outlet module can, for instance, be connected directly to a processing or bottling plant. Support collars and weld
ends are used for this purpose. In particular, screw-mounted support collars can also absorb the weight of the conveyor, so the need for additionalwall-mounting or frames is either partially or entirely removed.

Transition pieces from the vacuum conveyor to the product recipient can be tailored to the customer’s requirements.

The conveying properties of bulk materials

The transport properties of bulk goods,
materials and products
1. Transported material

3. Classification of the material

A vacuum conveyor system can be used to transport a range of different materials and products. This ranges from the finest powdery substances throughto small items several centimetres in size. Our conveyor systems are used in
the chemicals, pharmaceuticals and food industry as well as in metal andplastic processing and many other sectors of industry.

The size of a vacuum conveyor is heavily dependent on the material to betransported. This affects the diameter of the feed line, the output and qualityof the conveyor and other components. The following properties are determined to classify the material.
Properties of transported material:

Examples:• Powdery substances – lime, paint pigments, more…
• Granular substances – grains, coffee beans, sand, more…
• Coarse-grained substances – gravel, screws, more…
• Small items – cucumbers, diced ham, steaks, more…

• Flow property/angle of repose• Bulk density• Wear/abrasion• Particle size (distribution, shape, density, hardness)• Sensitivity to moisture (hygroscopicity)• Risk of explosion• Level of danger/toxicity

2. Material flow in a conveyor system
A certain ratio between the product mass flow and the air mass flow isrequired to ensure the flow properties of transported goods in the system.
This is referred to as the phase density.
If the product mass flow and the air mass flow are equal, no more air islocated in the transport line and it is blocked. By contrast, if the phase density is equal to zero, no material is to be found in the transport line. Various
phase densities occur between these two limits. We primarily distinguishbetween three phases. In the dense phase, the transported material moves
through the transport line in individual blocks. The speed of the product isquite slow.
In the strand phase, there are different manifestations of the product/air
mixture. The product is normally transported in the lower half of the pipe,
while a kind of dilute-phase transport occurs in the upper half. A switch between strands and blocks is possible. The properties of the phase are heavily
dependent on the product.
In the diluted phase, there is an equal distribution of the material/air mixture
in the transport line. This is where the highest product speeds are reached.
20 – 40m/s are possible.
Gentle product transportation essentially occurs in the strand and dense
phase. The best type of transport in the specific case depends on the productand process.
We analyse the transport capacity of materials in our laboratory for thispurpose.

Phase density =Product mass flow
Air mass flow

4. Flow property
The most important requirement for the transportability of a material whenusing vacuum technology is its fluidity. It depends on the particle size, particle geometry as well as the electrostatic and hygroscopic properties. While
granules generally display good flow properties, it is significantly poorer forother materials, such as various forms of powder.
The approximate flow property can be determined using a simple method.
When material is poured in piles on a floor, it either has a raised or flat
shape. The flatter the piles, the better the flow property.

5. Bulk density
The bulk density is the specific weight of the material with the air between
the particles, i.e. its weight if the volume is equal to a one-litre beaker. The
bulk density before the transport process is critical, as many materials canpass through various states of compression. It is important to know whether the transported material is loose or compressed under its weight.
The bulk density is important when selecting the optimal diameter of thetransport line. Most materials have a bulk density of between 500 and 900
grams/litre and require a larger pipe diameter. Smaller pipe diameters areused for higher bulk densities.

The conveying properties of bulk materials

6. Particles

9. Hazardous and toxic substances

To ensure the optimal size of the conveyor system, besides the flow properties and bulk density, attention must also be paid to the individual particles. This includes the particle weight (density), size, geometry, hardness
and particle size distribution. Particle weight and size are important factors
when determining the vacuum suction in order to raise the material in thetransport line.

Vacuum conveyors can essentially be used to transport hazardous substances, as they can be installed as a completely closed system. The constantvacuum in the system also prevents contamination of the outside air if minor leaks occur. The exhaust air discharged from the vacuum pump can becleaned by special filters or fed into an existing filter system.

If the transported material displays different particle sizes, it has an unfavourable particle size distribution. They can become entangled, which also
needs to be considered when dimensioning the system.

7. Sensitivity to moisture (hygroscopicity)
Hygroscopic substances may be deposited along the entire system duringtransportation and impair the filter performance. If the material agglutinates, this may block the transport line and the feed funnel. We test therespective material under realistic conditions in our laboratory and canconfigure the optimal conveyor system for your operation.

8. Risk of explosion
When transporting some substances, there is a risk of reaching a critical material/air mixture, which may lead to a dust explosion. This is generally triggered by electrostatic discharges. As the phase density constantly fluctuates
in a vacuum conveyor system, electrostatic reactions cannot be completely
ruled out. However, all components of a conveyor system are connected tothe same earthing point to minimise the risk of spark formation.
Some of the most common substances at risk of explosion:
Aluminium
AspirinCottonIron
CoffeeGrains
Cocoa
Timber

i

Coal
Cork
Tea
Flour
Sugar
Nylon

You can receive more information on this topic fromyour competent occupational health and safety
authority.

Another risk prevention option is the use of a police filter stage in the vacuum conveyor. If the first filter stage is damaged, the police filter stage takes
over the filtration activities until the other stage is replaced.

State-of-the-art vacuum technology is used for transporting all kinds of materials. In principle, this involves the same
technology used in a vacuum cleaner – the only difference lies in the transported material, the applications andthe power class. Boost your productivity by transporting materials more effectively. In a vacuum conveying system,
materials are conveyed in a completely closed system. Heavy lifting, dusty processing rooms and other sources ofcontamination are a thing of the past.

Lutena-BagStar

The Big Bag Station for vacuum conveying
This practical Big Bag Station for vacuum conveying is one of our latest products. It offers several
advantages compared to a smaller silo. The filling funnel, pipe connections, filters and taps are already
pre-installed. This means that it can be easily connected directly with the pipeline of a vacuum conveying system. In addition, LUTENA-BagStar is highly versatile in terms of its usage, is easy to transport
and is also very cost-effective.

Special solutions

Special solutions in vacuum conveying
Special measures are necessary when conveying and processing some materials, be they to prevent harm to the environment and people or to minimise production downtime and raw material losses. In many cases, the existing process
technology or spatial conditions call for special solutions. In all such cases, LUTENA-VAKUUM designs modules andadd-ons for your vacuum conveying system to meet your specific demands.

PECIAL SOLUTIONSPopular special solutions:• C onveyor with police filter stage• C onveyor with pinch valve as vacuum relief• D ust removal with a suck and blow system•M inimal maintenance• V acuum generation with electric pumps

Special solutions
Examples of possible special solutions
Vacuum conveyor with police filter stage

Our police filter stage is used in areas in which neuralgic substances are processed or where a regular filter
check cannot be ensured in a vacuum conveyor. A police filter stage contains a double-decker filter chamber. If
the first filter stage is penetrated, the second filter stage starts operation.
This system can also be designed with a differential pressure measurement with an interface to a central
control centre.

LUTENA VACDUSTer (dust removal system)

We also provide small dust removal systems based on our special modular design.
For example, these are used for dust extraction on tablet presses or in similar areas.
The Lutena VACDUSTer can be connected to existing dust extraction systems. Manual or automatic filter
back-flushing is also available. The LUTENA VACDUSTer can naturally also be fitted with a police filter level. It
is available with either a collection tank or with a discharge valve.
The discharge valve is based on our free-flow valve technology.

Suck and blow system
Our pneumatic suck and blow system is used if the LUTENA VACDUSTer operates in an EX area, or no central
extraction is available or desired.
An annular gap ejector sucks in the dust-laden air and then blows it into the LUTENA VACDUSTer.
The suck and blow system is extraordinarily powerful given its small size. It can easily be mounted to a transport line consisting of pipes or hoses. The suck and blow system is exclusively operated with compressed air,just like our vacuum pumps.

Vacuum relief system when using electric vacuum pumps

When using electric vacuum pumps, the vacuum supply to the conveyor needs to be shut-down and theconveyor needs to be ventilated.
This is where our pneumatic vacuum relief system is used.
A pinch valve supplies large volumes of external air to end the suction cycle.

Filter development

Dust and particle filters to the highest standards
Our many years of experience in the field of vacuum conveying technology have led to the development of special
filters for the various models of vacuum conveyors.
Examples include stainless steel filters made of woven material, which are ideal for pharmaceutical, food and chemical applications. PTFE-coated filters with a grade of filtration of 0.5µm are also available. These are used for very fine
products such as toner powder. A wide range of materials and filters can be supplied.

Product feed

Product feed for vacuum conveying
The shape of the product feed or intake point is an important factor to optimise the performance of a vacuum conveyor system. Almost all bulk materials require an appropriate false air volume to ensure safe transport. Or alternatively,
the material needs to be transported at an appropriate speed or in an appropriate transport phase.

MODULES AND EXTENSIONSWe provide different systems inorder to achieve this:• Feed adapters• Conveyor pipes• Conveyor guns

Bulk material technology
made easy…

31

Product feed

Feed adapters
Feed adapters are used in a range of sectors where products are fed automatically. It is used under silos or even in various feed stations.
A conveyor adapter has 2 points for adding false air:
1. Via the “horizontal injector”
2. Via the secondary supply air

1

2

Horizontal injectors
The horizontal injector allows the optimal adjustment of the location and volumeof the false air supply to the product. This prepared product/air mixture can then be
accelerated using the secondary supply air.

Feed nozzle
If a manual product feed is required, we recommend our double-walled feed
nozzle. The desired false air volume can be set by adjusting the position of
the inner pipe to the outer pipe. Both pipes are bevelled to facilitate immersion in the product.
It can also be manufactured with a suction basket on request. Our single-walled conveyor guns are used for the simplest applications.
