Application Bulletin: Fermentation Broth Clarification For Food And Feed Ingredients
Producers of bulk food and feed ingredients such as amino acids, organic acids, and vitamins use fermentation as the basis of their production. Today's modern industrial biotechnology processes use carefully selected and purified microbial cell cultures to produce an ever-increasing variety of ingredients and increase productivity.
A large producer of feed additives and vitamins needed technology to manufacture a variety of products in an enclosed system. Due to changing market conditions, this producer desired a degree of flexibility in operation matched to the particular product type being manufactured.
Membralox® ceramic crossflow technology was chosen for this new, state of the art facility for its ability to reliably deliver the highest filtrate quality regardless of broth characteristics. Unlike centrifugation, where cell size and density as well as fluid viscosity influence the separation efficiency, membrane separation offers an absolute physical barrier that will always provide the optimum separation.
Additionally, ceramic technology provided a solution which could operate without incurring the storage, handling and waste typical of filter aid-based precoat technology. An additional advantage of this solution is the ability to further use the product retentate stream, for example by drying it for use as animal feed.
