Dewatering and drying

We have pursued drying-related research and development since 1989. We have experience of the drying of biomass, paper, crops, and clothes, and we are constantly in the process of extending and deepening the knowledge of drying-related research and development.

The aim of our research and development is to contribute to the production of energy efficient and environment-friendly drying processes. Our resources to achieve this are suitable premises and equipment, staff with different areas of expertise, and well-functioning routines for picking up and processing the problems that industry and society bring to our attention.

Issues can be raised at different system levels. Applied research and development projects predominate, but also curiosity-driven research and development play important roles. Research issues can be theoretically or empirically based.

Some general research objectives of this group are

Two general research objectives are

  • to contribute to the development and implementation of energy efficient and environment-friendly drying and dewatering processes.

  • to establish a competitive dewatering and drying research group that is an attractive partner for the Swedish pulp and paper industry including suppliers and consultants.
