Vogelbusch Technology

Vogelbusch offers state-of-the-art proprietary technology for every stage of the ethanol process. Proprietary processes include

MULTICONT continuous fermentation

In 1980, the Vogelbusch MULTICONT continuous fermentation process was introduced to the U.S. with resounding success. Over the years, this process has been refined and is now considered state-of-the-art technology for yeast fermentations. This process is reliable and will operate in a steady-state for extended periods of time, provided that routine cleaning is performed. Final alcohol concentrations of over 14% (by volume) are regularly achieved, and excellent yields are obtained. The process lends itself to full automation and has considerably lower capital cost requirements compared to older technologies.

Heat integration

A further innovation introduced by Vogelbusch to the alcohol industry is the integration of distillation, evaporation, molecular sieve dehydration, and DDGS drying. This design minimizes both energy requirements and initial capital costs but does not overly complicate operations. The heat integration in this proprietary system allows multiple effect evaporation to be driven by waste heat from distillation and the DDGS dryers, while the condensation of the dehydrated alcohol vapor from the molecular sieve unit provides the heat input for beer preheating.

Recent developments with integrated energy-efficient DDGS dryers and evaporators have enabled Vogelbusch to introduce a new generation of alcohol plants that significantly reduce overall energy consumption. These innovations, together with environmentally responsible designs, have contributed significantly to the commercial success of fuel alcohol plants designed by Vogelbusch.

Through continuous development work by the parent company in Austria and by maintaining close contact with the operation of our plants all over the world, Vogelbusch stays on the cutting edge of technology.
