Power is provided by means of a prime mover. Note that the term “agitator” refers to the entire machine some people incorrectly use this term to apply to the impellers only. To begin, it is useful to identify the major components of an agitated tank, as shown in Figure 1.įigure 1, typical agitated tank Let us follow the flow of power through the system, identifying the nomenclature and standard symbols as we do so. We will also cover the basics of heat transfer calculations. Likewise, mechanical design is not covered, both due to time limitations and the availability of such information in more generic agitation courses.Ĭhapter One: Agitator Design Basics In this section, we will cover nomenclature, standard symbols, basic concepts, principle dimensionless numbers and the main classifications of flow patterns. Solids suspension is not covered, as serious solids suspension applications are rare in these industries, and are covered in more generic agitation courses available in the marketplace. An introduction to advanced tools such as Computational Fluid Mixing (CFM) is given, and sanitary design issues are addressed.

Considerable time is devoted to fermenter and bioreactor design, including how to pilot in such a way as to get the kind of data which is useful for agitation scale-up and energy cost minimization. The course begins with a basic introduction to agitation terminology and principles, then progresses through design concepts for liquid motion, gas dispersion and scale-up. A basic Introduction to general agitator design principles is given, but the focus is primarily on applications found in the Pharmaceutical/Bioprocessing Industries. The application technology ranges from simple to complex, and the construction details range from standard to highly sanitary. Typical applications in these industries might include, for example, simple tanks containing CIP solutions, broth and slurry tanks, compounding tanks and fermenters/bioreactors. Introduction This course is intended to aid those in the bioprocessing, pharmaceutical and food industries who must specify, purchase, operate, troubleshoot or perform research involving agitation equipment.
