Drying systems for bioethanol production
Optimize your bioethanol production with advanced evaporation and drying equipment, ensuring efficient conversion of feedstocks into high-value end products like bioethanol, high-protein feeds, and bio-based chemicals.

Processes Bioethanol and High-Protein Feed Products
The Bioethanol Production and Processing Systems from VetterTec GmbH are engineered to support first and second-generation ethanol plants. These systems integrate stillage evaporators, high-protein animal feed dryers, and sophisticated mixing systems to optimize biofuel and protein production. Employing a closed air system to minimize emissions, they ensure energy efficiency with advanced evaporators and dryers selecting from VetterTec’s extensive range of technologies. Applications span bioethanol, DDGS, yeast extract, and plant-based protein concentrates, with a capacity for large-scale, continuous processing. Built for automation, these systems align with operations in agrifood, starch, grain, and chemical industries, and offer easy integration with your existing production line. Available in materials designed for corrosion resistance, they meet industry standards and allow for tailored configurations to suit production needs.
