Economical Preparation of
Processing of Biopolymers
As crude oil and gas becomes
scarce and more expensive, chemists and plastics
engineers all over the world look for new, sustainable
raw materials and new technologies to produce polymers.
Biopolymers are produced
from annual crops and plants like wheat, corn, potato
and sugar cane and other new alternatives now being
developed for the production of food packaging materials
like film sheet and foam containers. i.e. PLA
While producing such
products, size reduction, compounding and recycling
technologies play a major role. This is the area
where PALLMANN specialists are pioneering and leading
the way with ecological and economical solutions.
In the world's largest research and technology center
for size reduction, PALLMANN offers an unparalleled
opportunity for all those working on technologies that
will change tomorrow's world.
Special techniques have been
developed in recent years, enabling us today to offer
processes such as shredding and fiberizing of annual
crops and plants, compounding the biopolymers with
additives and pigments, pulverizing granules and inline
recycling during the production of film sheet and foam
Preparation of Plants
Industrial processing of
renewable new materials is being driven forward
worldwide; whether it is for the usage of the fiber
components, the pith for the production of fodder, for
gaining ingredients such as proteins and vitamins, for
the extraction of oil and alcohol or for the production
of thermal energy.
PALLMANN has developed
suitable processes and machines that allow the
economical preparation of renewable raw materials.
Customer requirements are very diverse. Vegetable
matter is to be prepared for extraction into homogeneous
end products without a high percentage of fines.
Cell structures are to be
broken down in order to be able to better press the
contents. Fibers with a defined length or width
are to be gained in order to increase the physical
of composite materials. Voluminous feed materials
are to be processed automatically, if possible, in order
to be able to feed downstream processes.
The waxen layer on steams must be roughened in order for
glues and adhesives to stick. Vegetable matter
contains natural foreign objects such as sand and stones
as well as other disturbing matter, i.e. metals and
plastics that must be removed automatically during
processing, if possible.
requires special machinery, for example, with ballistic
discharge system components such a heavy gravity
sifters, stone traps, over belt magnets and non-ferrous
Machines with a high wear resistance that are not
sensitive to feeding fluctuations are required.
Installed in process lines, the machines operate around
the clock. Scheduled downtime for maintenance is
normally planned on an annual basis. The machines
used for these purposes distinguish themselves by their
flexibility in the adjustment of technical process
parameters and absolute reliability.
