The chair of mechanical process engineering of the University in Dortmund invited to the symposium "Spray Drying '01„ to treat the various applications, techniques, and modern developments concerning spray drying and related processes. Objectives of the conference Spray dryers are used in industry in various applications to produce solid particles from liquid feeds such as suspensions, solutions, or even melts. In recent years the basic knowledge in describing and modelling of spray towers has significantly increased. Improvements on spraying systems and air flow distributors contribute to better performance of the process. It was the objective of the conference to exchange information on the following fundamental topics: Spraying and formation of liquid particles, Heat and mass transfer between gas and particles, Transition to the solid state and particle morphology, Agglomeration of fine particles. Depending on the customer requirements different particle sizes and specifications are desirable. The operation parameters therefore vary over wide ranges. The meeting also had to deal with operational conditions such as · Co or countercurrent flow · Heat recovery · Secondary drying and agglomeration · Dust removal and waste gas treatment · Product separation and discharge · Process and molsture control. Resume of the conference The conference “ Spray Drying" was held in Dortmund from October 8 to 10. In total 39 participants from outside Dortmund and about 8 participants from the university attended this workshop. After the last session, a questionnaire was collected. The evaluation found the majority whould suggest to have another meeting within 2 years. For those who intend to give a lecture in 2003, there is a large catalogue of issues to be covered in the future.
