Information about the Working Party


The EFCE Working Party was set up in 1980 to provide a forum for drying experts from academia and industry to meet and exchange knowledge and experience. The first chairman was Prof. Ernst Schlunder of the University of Karlsruhe, Germany.

Since then, the Working Party has met regularly and has organised or supported many technical meetings, including a number of the International Drying Symposia (IDS) which have been held in Europe. Plans for future EFCE Drying Working Party meetings and supported events can be found on the Events page.

Full details of the EFCE, its history, the national member societies and the other working parties can be found on the main EFCE information page at

Aims & Objectives of the EFCE-WPD

to promote science, technology and education in solids drying in EFCE member countries and worldwide;
promotion of interaction between academia and industry, to allow improvement of drying science and technology and encourage applications in industry of the latest scientific models and discoveries;
international exchange of knowledge and experience, between scientists as well as between scientists and practising engineers;
information exchange about the main trends in research on drying performed by the EFCE member countries, i.e. countries having delegates in the WPD;
information about conferences and meetings held or planned to be held in those countries, and other major international conferences (e.g. International Drying Symposia);
information about activities of national working parties on drying of the EFCE member countries;
to contribute to the definition of standards, nomenclature, recommended techniques and other good practice in drying;
provision of links to other important sources of information on drying and related subjects;
any other activities leading to the development and promotion of drying technologies.

Drying is defined here as: producing a dried solid by removal of liquid by evaporation, through supply of heat. (Drying through mechanical forces, e.g. centrifuges, or by non-thermal processes, e.g. osmotic dehydration, is excluded, as is drying of materials other than solids, e.g. gases. However, processes which do not begin with a solid feed, e.g. spray drying, or generate heat indirectly, e.g. RF and microwave drying, are included).

Drying can be treated as a unit operation, or as part of material processing (product engineering). Drying is important for integration (process systems engineering).
