Extrusion 1-2017

38 / 52

Tecnova is always at the forefront in recycling
equipment for all polymeric materials, with
the realization of extrusion lines suitable for
all needs of the industry, from laboratory
systems up to lines of two ton/hour capacity
that can process the various types of plastics,
and competitive way to manufacture
new products. Another critical issue is al-
so the fact that many companies, opti-
mizing their internal processes, are able
to reuse internally the recycled material
less contaminated.
Savings and reliability
An aspect not to be overlooked is the
energy savings of Tecnova plants, ob-
tained by installing AC motors. Further-
more the Tecnova lines are versatile, reli-
able and with a mechanical configura-
tion which facilitates access to the diffe-
rent parts during maintenance.
Regeneration of plastics is constantly
evolving; for this, it is essential for a
recycler to have the best performing and
reliable equipment over time. Today the
process requirements are driving more
and more frequently towards the recy-
cling, processing and exploitation of ma-
terials with a high degree of contamina-
tion and moisture, as in the case of
strongly printed products.
Moisture removal
The double degassing systems of Tecno-
va are able to remove moisture up to va-
lues of seven to eight percent, which can
vary up to ten percent thanks to the new
degassing system developed and called
VTS (Vacuum Twin Stuffer). As part of a
constant research aimed at continuous
improvement of single-screw extrusion
lines, it has been developed the natural

degassing VTS system with automatic re-
store of the melted material; this compo-
nent is able to double the capacity of the
lines, both single and double vent, pro-
cessing material with high moisture con-
tent.
This results in a proportional increase of
the hourly production of the lines with
equal amounts of material being pro-
cessed. With these solutions, it is there-
fore possible to remove the eight to nine
percent of humidity.
Development of new solutions
The Tecnova technologies have been
strengthened over the years, following
the evolution of the market and custo-
mers' needs: on one hand the need to
process more and more contaminated
materials and on the other to obtain a
product that can be used in a convenient
