Abstract [en]

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.
