Abstract [en]

This thesis studies paper and what it is made of and different ways to manufacture it in a laboratory scale. It also contains a comparison of different ways to dry tissue and which method that suits a small laboratory tissue machine best.

 A small paper machine was found at Metso in Karlstad that was used as a basis for the concept machine. Since the machine at Karlstad used pressing and a cylinder drying method that involves pressing an alternative method to dry the paper had to be chosen.

For drying tissue there are several methods like, infrared and through air drying. A comparison was made between those methods to find out which suited the specification best.

The comparison shows that through air drying is the best drying method for the machine.

Abstract [sv]

I detta examensarbete studeras hur man tillverkar papper och olika sätt att tillverka papper i laboratorium skala. Den innehåller också en jämförelse av olika sätt att torka papper och vilken metod som passar bäst till en liten pappersmaskin.

En liten pappersmaskin hittades vid Metso i Karlstad. Den användes som grund för vårt förslag till maskin. Eftersom maskinen i Karlstad använde ett pressparti och flera torkcylindrar till att torka arket så behövdes de bytas ut. En jämförelse mellan olika torkmetoder gjordes för att finna en ny lämplig metod för ändamålet.

Litteraturstudien visar att det finns flera torkmetoder så som infraröd torkning och genomblåstorkning. En jämförelse gjordes mellan dessa metoder för att ta reda på vilken passade specifikationen bäst. Jämförelsen visar att genomblåstorkning är det bäst lämpade metoden för maskinen.
