U-Loop® Fermentor

THE U-LOOP® FERMENTOR

In traditional stirred fermentors there are problems with achieving sufficiently small bubbles (large surface area of the gas), and there is a large energy waste due to inefficient stirring of the bulk liquid. Furthermore, there are problems with cooling when upscaling.

Uniprotein® is produced in a continuous fermentation process. A U-Loop® fermentor with static mixers is used. The U-Loop® fermentor gives a high utilization of the gases, which are carried through the loop by the liquid flow in almost plug-flow mode. The gases are introduced at the start of the loop and stay in well-mixed contact with the liquid until they are separated in the headspace (see below) at the end of the loop.
