How big can a fermenter get? And what would the biggest fermenter look like? The answers to these questions depend upon how the requirements of heat transfer, mass transfer (gas-to-liquid), and momentum transfer (mixing) are met. In an earlier article (Heat Transfer for Huge-Scale Fermentation, Chem. Eng., November 2013, pp. 44–46) the authors described how heat-transfer requirements can cause...

Pressure to become more flexible and provide shorter cycle times have prompted chemical processors to examine their mixing operations to determine whether there is a way to increase process efficiency via mixing equipment. And, they just might be onto something, as modern mixing systems are designed for particular process requirements and mixing tasks, allowing them to operate efficiently. The greater...

The scaleup of liquid mixing systems does not have to be a mystery. The principles are quite well understood, although knowing which principles apply is not always obvious. Follow this guidance to improve operation. 1. Liquid mixing scaleup. Liquid mixing is the most common use of scaleup methods in chemical engineering. The concept of scaleup is to take small-scale results and predict results in...

Among all the engineers who will be involved in the purchase of a mixer or blender next year, roughly half will welcome a change in their production method. The other half will be determined to prevent it. Searching for the right equipment to make a new product or boost current production, about 50% of users will conduct open-eyed tests in the laboratory of a mixing equipment manufacturer.1 They will test...
