Reducing Particle Size Increases Accessible Surface Area

By increasing the amount of entrapped starch that is released, the resulting yield from the same amount of corn can be increased by 3% to 5% or more 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 following diagram 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 photos below show the difference between CFC™ treated and untreated corn “mash.” The photo on the left is uncavitated corn mash. As you can see from the photo on the right, CFC™ disrupts cell walls and liberates the entrapped starch molecules. This increases accessibility of starch molecules to enzymes, which leads to a higher sugar and ultimately higher ethanol production.

Destruction of the Cell by Cavitation

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

Arisdyne's technology is the only patented process using hydrodynamic cavitation on the market today.
