Optimering av påstorkning
Från behov till färdig konstruktion
This thesis describes the redesign ofequipment designed for drying bags thatis used in Fresenius Kabis´manufacturing of their nutritionmedicine in Uppsala. The need of thistask arise during the start of thedevelopment of a new packaging line werethis equipment were meant to be used. Anevaluation of the bagdryers capacity andcapability was necessary.The work started with gathering ofinformation from suppliers of the usedcomponents and from the responsibleengineers for this equipment. Aneducation to learn how the equipmentworked and how to operate it were taken.That was followed by the creation of astudy plan were the tests were plannedto test different parameters effect onthe drying result and to see if thebagdryer managed to handle the bags ofthe correct format in the pace that theequipment should be designed for.The test results detected a need ofdesigning a unit with a function thatholds the bags in place while passingthrough the dryer in order to attainhigh quality results. The results werelater used for optimization of thedesign. The parameters that had thebiggest effect on the result were thedistance and the airflow.When the concepts were chosen thedetailed design was initiated and theresult of this is described in chapter 7Resultat. Shortly, the result from thedesign work can be described as a unitthat holds the bags in place whiledrying. The unit.s height is adjustableand the air knives tilting angle andheight can also be adjusted. With thisunit installed, the equipment will beable to meet the new capacity demandwhich is set on it. Continued work onthe design is recommended in order toreduce the designs weight and to verifythat the design is strong enough.
