New concepts for the starch industry: Glucose demudding by a decanter membrane synergy process
(2012) ACHEMA 2012- Abstract
- The starch industry is a key sector of the European food industry with an annual turnover of approx. €4 billion. The production processes in the starch industry are still dominated by conventional separation processes such as evaporators, separators and rotary vacuum filters (RVFs). Membrane processes are only rarely used.
This presentation will show how membrane processes can be used to optimise one of the key steps in the production process, the demudding of glucose, a starch-based sweetener, after saccarification. This step is conventionally dominated by RVFs with a diatomaceous earth (kieselguhr) coating removing the so-called mud phase —consisting of enzymes, proteins etc. In this novel approach, a synergy process consisting of a...

The production processes in the starch industry are still dominated by conventional separation processes such as evaporators, separators and rotary vacuum filters (RVFs). Membrane processes are only rarely used.
This presentation will show how membrane processes can be used to optimise one of the key steps in the production process, the demudding of glucose, a starch-based sweetener, after saccarification. This step is conventionally dominated by RVFs with a diatomaceous earth (kieselguhr) coating removing the so-called mud phase —consisting of enzymes, proteins etc. In this novel approach, a synergy process consisting of a two-phase decanter combined with ultrafiltration spiral wound modules is used for demudding. This approach not only overcomes the disadvantages commonly linked to the use of kieselguhr, such as high disposal costs, sugar losses in the mud fraction and safety of operators, it also achieves higher colour removal therefore reducing the load on the subsequent ion-exchange columns. The presentation will document the development of the synergy concept from independent decanter and membrane tests in the starch industry over pilot trials of the concept at wheat starch producer, to the installation of the first full-scale unit at a corn-starch producer.
Overall, the presentation will give an example of how the combination of membrane technology with a conventional separation process in synergy process can improve the production of glucose and therefore contribute to a sustainable growth of the starch industry.
