Maximum Starch Extraction for Higher Yields

Ethanol production begins with starchy grains. Today feedstock is reduced to particulates by mechanical milling and then mixed with water in line.  The resulting slurry whether corn, milo or other fibrous materials can now be pumped into the Arisdyne CFC™ controlled cavitation device.  Powerful cavitation forces completely fracture the corn structure particles, exposing additional entrapped starch molecules within the cellular structure, thus enhancing hydrolyzed enzymatic efficiency in the “mash”.

Reducing particle size increases accessible surface area. By increasing the amount of entrapped starch that is released, the resulting ethanol yield increase with corn feedstock can be increased by 1% to 2.5% and 2% to 4% or more with small grains (such as wheat, barley, rye, or triticale) with essentially no additional energy input and lower total feedstock costs.

The application of controlled flow cavitation prior to saccharification improves particle size and rate of starch-to-sugar conversion for subsequent fermentation to ethanol.  Ethanol can then be more efficiently generated through fermentation and subsequent distillation.

The diagram below shows the effect from controlled cavitation to the particle size distribution in corn slurry.  You can see that larger particles get smaller whereas small particles stay at the same size. CFC™ does make particles more uniform and narrow the particle size distribution.

The SEM photos below show the difference between CFC™ untreated and treated corn mash. (Similarly, photos of sorghum or milo reveal the same cell disruption).  The SEM photo on the left is uncavitated corn mash.  As you can see, the photo on the right shows how CFC™ fractured cell walls and liberates entrapped starch molecules. This increase accessibility of starch molecules to enzymes, leads to a higher sugar content and ultimately higher ethanol production.

By creating substantially greater surface area in the dispersion, our CFC™ optimizes the efficiency of the enzymes and opens to further cost reductions.

Arisdyne’s technology is the only patented process usingHydrodynamic Controlled Flow Cavitation”

The illustration below depicts a typical CFC™ system for plants ranging in size for 30 – 130 MMGPY.  It is equally adaptable to ICM, Delta – T and most other ethanol producing facilities.

The photo group of Arisdyne CFC™ units is a typical representation of an installed system in an ethanol plant.  As you can see the components are easily set up in line within an existing plant without the need to build a new facility or locate the system outside.
