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.
