10th University Course Fluidization Technology


Fluidization technology has a tremendous economic importance and is used for a wide range of physical and chemical processes like classification, drying, adsorption, heating and cooling of solids, combustion, pyrolysis, carbonization, gasification, calcination or gas-solid reactions.

In this course we focus on the drying as well as on the spray granulation, coating and agglomeration in fluidized beds. The particle formulation processes play an important role in the manufacturing of powder granules from liquid educts in the food, fine chemicals, biotechnological and pharmaceutical industries as dust-free and free-flowing particles with defined particle size distribution and desired mechanical strenght can be produced in a process with favorable heat and mass transfer conditions and good solids mixing.

Additional advantages of this size-enlargement process are the possibilities to improve particle properties, like appearance, taste and odor or the protection from oxygen, humidity, light or incompatible active agents as well as the adjustment of the controlled release of active components (e.g. drug).

This course highlights the fundamentals and applications of various fluidized bed processes for drying, coating, granulation and agglomeration of particles with practical hints and extensive calculation examples. The focus is on fluid mechanics, mixing, heat and mass transfer and particle formulation mechanisms. Furthermore, actual applications as well as modern computational tools and measuring techniques are presented. Practical process demonstrations in leading laboratories and tutorials will strengthen the acquired knowledge.

Target Audience

The course is designed for people from various backgrounds (engineers, chemists, food and pharmaceutical technologists) and with different levels of experience, who need to understand the fundamentals of applications of modern and efficient fluidized bed processes. The course language is English.
