Glacial Lakes Energy Installs Arisdyne System’s Controlled Flow Cavitation System to Enhance Ethanol Yield

Arisdyne Systems and Glacial Lakes Energy Collaborate to Test and Demonstrate Controlled Flow Cavitation™ System Increases Ethanol Yield by Releasing More Starch from Corn

MINA, SD and CLEVELAND, OH (June 7, 2013) -- Glacial Lakes Energy recently installed Arisdyne’s patented controlled flow cavitation (CFC™) system at their Aberdeen Energy facility in Mina, South Dakota. Glacial Lakes Energy (“GLE”) and Arisdyne collaboratively demonstrated that the CFC™ System increased daily average ethanol production and performed above the test agreement of 1.5%.

“After evaluating several yield increasing technologies, including new enzymes, it made a lot of sense to test Arisdyne’s technology due to the simplicity, small footprint, and lower operating expenses” remarked Frank Moore, Director of Operations for GLE. “Arisdyne’s service model allows higher margins without upfront capital for machinery, and it includes full maintenance of the cavitation device and technology enhancements in a justifiable monthly fee.”

Commenting on the ease of installation, Glacial Lakes Energy’s Production Manager Tim Crabtree stated, “It only took two weeks to complete the make ready work and system installation; and only four hours to tie it into our plant’s process. Since start up of the equipment, it just runs.”

Shortly after startup, both teams began to validate the anticipated improvements. “Arisdyne has a very precise and comprehensive test protocol at full commercial scale,” stated Validation Engineer, Bill Herdt. “Full-scale testing provides a higher confidence level for most customers than mere slipstream testing.”

The yield enhancement principal and design of applying cavitation to slurry materials in order to liberate recalcitrant starch is well established. Arisdyne’s patented CFC™ devices and processes apply this high shear technology, in line, to open the corn cell structure efficiently, expose the starches to water and enzymatic activity more aggressively, and reduce particle size -- all contributing to lower viscosity and more complete front-end processing. Other approaches offer options for finer grinding, more intense heat and steam treatments, or more aggressive enzymes to liberate/convert more starch to sugars, but at higher processing costs, greater energy consumption, or capital investments requiring space and maintenance.

The ethanol industry is constantly tasked to find new methods and technology to improve the economics of corn and other grain based ethanol. “Arisdyne offers a proven technology. The combined capacity of ethanol producers using Arisdyne’s CFC™ technology is approaching 500 million gallons per year," remarked Fred Clarke, Executive Vice President of Arisdyne, “translating into nearly 15 million additional gallons per year to the ethanol industry. It’s just another example of how Arisdyne helps the ethanol industry to improve margins.”

About Glacial Lakes Energy, LLC

Glacial Lakes Corn Processors is one of the largest cooperatively owned ethanol facility in the United States, with more than 4,200 members. It is based in Watertown, South Dakota, and operates 100-million-gallon per year ethanol plants in both Watertown and Mina through its wholly-owned subsidiaries. The ethanol plant in Mina became operational in 2008. Glacial Lakes Energy also has ownership in Granite Falls Energy and Redfield Energy.
