Visit with us at the North American SAF Conference & Expo

St. Paul, MN – St. Paul River Centre – Booth 131
September 11-13, 2024

We’re excited to present our solutions for processing ethanol to attendees at the North American SAF Conference & Expo. The program at this event is designed to promote the development and adoption of practical solutions for production of sustainable aviation fuel and the decarbonization of this transportation sector. 

GEA centrifuges have been employed by the ethanol industry for over 30 years with hundreds of machines running production. Besides producing ethanol, they are used to extract and purify valuable co-products. As the SAF industry expands, our commitment to environmentally sound fuel production is strengthening. Continuous testing and modifications of the equipment and process are both improving efficiency and economic viability.

If you have questions about the process and the equipment required, we have the answers.

Here’s what you can learn about at the GEA booth:

1) Whole Stillage Decanters 
With a compact design and small footprint, these decanters produce cake with >40% DS. This is due to deep pond design with high g-volume, automatic differential speed adjustment and always full torque. Featuring an energy efficient design, units provide robust and reliable operation.

2) Oil Skimming Decanters with GEA varipond® C
For maximum product yield, these robust units are capable of handling high back pressures. Our decanters are placed ahead of the whole stillage decanters to maximize the amount of corn oil available in the process. Known for long service life and maximum availability, these decanters are easy to operate and monitor. GEA varipond® C is used to adjust the corn oil level.

3) Corn Oil Recovery from Syrup
Corn oil is separated from thick stillage using a disk centrifuge after the evaporator. The centrifuge features all stainless-steel contact parts and a belt drive with VFD for low maintenance. Our fine tuner can be easily adjusted to add water to the oil phase based upon needs.

4) Corn Oil Recovery from Thin Stillage
To increase the amount of corn oil recovered, separation of thin stillage using a disk centrifuge can also occur before evaporation. This process produces a clean heavy phase and protein rich solid material for drying or mixing with your DDGS, providing the most flexibility and income potential to the processor. Corn oil separation by disk-stack centrifuge requires less energy and reduces the processors carbon index.
