Correcting Mixing Failures

Correcting Mixing Failures

How does the industry intend to expose the applications that did not meet expectations? And what is the procedure for achieving that?

Mixing is a critical operation which determines the quality and properties of the products in the chemical, pharmaceutical, food and other related industries. Improper mixing can result in high product rejection, which may only be realized much later in the manufacturing process. The cost of improper mixing can have significant impact on the product bottom-line.

More often than not, improper mixing is a result of incorrect selection or design of the fluid mixing equipment, agitator. With the myriad of mixing equipment available, it is a matter of understanding and application which is required, to identify the most suitable equipment.

There are several instances where the mixing performance falls short of the user expectation. Improvements can be brought about identifying the gap between the existing operation and the required performance, and experimenting with changes in the process (if permissible) or through design modifications, changes in operating parameters of the equipment. In most cases this knowledge remains limited to end users and equipment manufactures. The end user prefers to maintain secrecy about special processes and equipment. Likewise the equipment manufacturers likes to safeguard what they have learned, and use this information in business interest. In some cases however, equipment manufacturers provide case studies which are available in public domain and may be informative.

Considering the wide variety of industrial applications, not every application in mixing has been studied and many applications are difficult to model computationally. As a result, it is sometimes laboratory trails become necessary.
