Abstract

The paper is concerned with continuous measurements of the rheological properties of fermentation broth. An on-line rheometer “Rheohelix-1”, based on the application of a helical screw impeller rotating in a draught tube, has been constructed. The instrument was used for measurements of the rheological parameters of fermentation broth of Aspergillus niger in a submerged fermentation process. The results of rheological and standard measurements have been compared.
