This thesis describes the redesign of
equipment designed for drying bags that
is used in Fresenius Kabis´
manufacturing of their nutrition
medicine in Uppsala. The need of this
task arise during the start of the
development of a new packaging line were
this equipment were meant to be used. An
evaluation of the bagdryers capacity and
capability was necessary.
The work started with gathering of
information from suppliers of the used
components and from the responsible
engineers for this equipment. An
education to learn how the equipment
worked and how to operate it were taken.
That was followed by the creation of a
study plan were the tests were planned
to test different parameters effect on
the drying result and to see if the
bagdryer managed to handle the bags of
the correct format in the pace that the
equipment should be designed for.
The test results detected a need of
designing a unit with a function that
holds the bags in place while passing
through the dryer in order to attain
high quality results. The results were
later used for optimization of the
design. The parameters that had the
biggest effect on the result were the
distance and the airflow.
When the concepts were chosen the
detailed design was initiated and the
result of this is described in chapter 7
Resultat. Shortly, the result from the
design work can be described as a unit
that holds the bags in place while
drying. The unit.s height is adjustable
and the air knives tilting angle and
height can also be adjusted. With this
unit installed, the equipment will be
able to meet the new capacity demand
which is set on it. Continued work on
the design is recommended in order to
reduce the designs weight and to verify
that the design is strong enough.
