Mixing, especially for unusual processes or unique equipment, often requires development testing. Scale-up provides a means for doing small tests. The results of scale-up can be used to understand and design, or modify large-scale equipment. Exploring the unknown is an essential beginning to successful scale-up. The process dynamics and limitations need to be known before successful applications can be understood and applied.

Existing processes benefit from a better understanding gained through small-scale testing. The ability to try new ideas without disrupting production can provide opportunities to improve process results and increase profit potential. However, scale-down is not without its own challenges, as not everything behaves the same in a small-scale test. Therefore, identifying the critical factors is no less important.

Often understanding one small-scale mistake can be one of the best pieces of information for successful scale-up. Just do not make the same mistake again, especially in the large-scale process.

This Webinar provides insight into some essentials of mixing scale-up. You learn that how you conduct the tests can be as important as how you analyze the results. Each situation has unique characteristics, but proper scale-up methods can guide a successful development process. This Webinar is for anyone doing development work on processes involving fluid mixing.

Dr. David Dickey started his own consulting business called MixTech, Inc., in 1998. Since then he has done independent consulting work to solve process and mechanical problems with various types of mixing equipment.

Much of David’s liquid mixing experience comes from a fifteen year career with Chemineer. As technical director for Chemineer, he helped develop a new impeller and several design procedures. His experience with customer lab tests provided him many opportunities for successful scale-up to process size mixers. David also worked for Patterson-Kelly, a manufacturer of...Read more
