VPT
EKATO SYSTEMS GmbH
offers " made in Germany "
technology for mixing
pasty products with high
solid contents.
Q
uick and effective
blending of
such products requires
agitation systems
with high torque.
Both Z-kneaders and
horizontal ribbon blenders
are quite expensive
and difficult to discharge
completely.
The EKATO SYSTEMS VPT
Sewage Sludge Drying
With Thin Film Dryer up to 95% DS
hin Film Dryers have proven themselves
in municipal and industrial
sewage sludge drying since
1985 world wide. In Germany
42.162 tons dry matter from
municipal sewage sludge
were processed by Thin Film
Dryers in 2017. By end of
2020 this number will have
increased significantly. Two
big new facilities will be
started up then.
EKATO
vertical process blender offers
25% less torque demand and
a discharge of up to 98%, compared with
horizontal drum blenders.
The VPT features a heavy-duty " top entry "
agitator, combined with a baffle system designed
for liquid and solids blending to reduce
both operation costs and batch times.
The high impeller efficiency reduces energy
input into the blend and avoids an excessive
temperature rise during the batch cycle.
Benefits:
* vertical system with lower investment
and maintenance costs compared to horizontal
systems;
* no product wetted seals mean longer life;
* GMP-compliant design available;
* fast liquid incorporation in bulk solids -
30% less batch time;
* high-yield discharge system for maximum
yield of valuable product - up to 98%;
* commercially proven design;
* worldwide sales and service network.
Applications:
* PVC in methylene chloride paste;
* aluminum/water paste;
* pigments in petroleum paste;
* graphite plus water/oil paste;
* cocoa powder/palm oil paste.

IPCO: Highly efficient solidification
solution for hot melts
in form of its flagship Rotoform system
he Rotoform process delivers consistently
sized, hemispherical pastilles. As
this is a completely dry system based on
indirect cooling, there are none of the problems
associated with underwater granulation,
and the product leaves the system in
a cold, solidified (i.e. non-sticky) state, ensuring
clean, trouble-free packaging.
Key benefits of Rotoform solidification
include:
* Size reduction in liquid phase.
* Free flowing end product.
* High quality pastilles, adjustable from
2-30 mm.
* No drying necessary as no contact between
product and coolant.
* Low maintenance requirements.
* Regular appearance, defined weight and
volume.
* High bulk density and good packaging
properties.
* Dust-free production and product.
* Very low vapor/gas emissions.
* Low energy consumption.

requirements,
but a typical Hot
Melt Adhesives
processing system consists of remelting
equipment for wax, a pair of mixing reactors,
the Rotoform drop depositor (or strip former
and cutter), steel belt cooler and downstream
bagging and weighing equipment.
Typically, resin, premelted wax and
polymer are blended in a mixing reactor
on the level above the solidification plant.
While one batch is prepared, the batch that
has already been mixed is transferred to
the Rotoform unit, a process that enables
continuous pastillation.
The upstream part ensures that all ingredients
of the hot melt are melted and
mixed at the required temperature.
IPCO offers complete hot melt processing
plants covering everything from initial system
design, through solidification, to granule packaging
solutions. Plants offer a high degree of
flexibility, allowing quick and easy switchover
between different types of hot melts.

The technology ascertains
safe and reliable operation.
Spreading the sludge in
a thin film on the heating wall by
wiping blades offers a small product
hold up of approx. 10 kg sludge per
m2. It enables to generate every concentration
of dry substance up to 95%. Even
the sticky phase, which occurs at sewage
sludge between 45-60% DS, causes
no problem, either in constant operation
or after unexpected stops. Emptying is
not needed and re-starting can be done
without additional precautions. Thin
Film Dryers accept all typical inlet sludge
T
types. Indirect heating provides perfect
conditions for vapour condensation and
excellent conditions for direct connection
to an incinerator. Thin Film Drying systems
do not need ancillary equipment for feed
product preparation or for dry material
shaping. Maintenance is simple and does
not require specialists.
