Ethanol Fermenter

MuPor industries has designed and patented a novel rapid fermentation bead system that has reduced fermentation time from 36 hours to just 6 hours. These beads have been shown to be effective for bench-top scale fermentation and microbrewery purposes, but their full potential will likely require a specifically designed fermenter tailored to the design of the beads at a large demonstration scale (~200 gal.).

Design Task
BioEx beads can quadruple the production capacities of ethanol industries, whilst increasing ethanol yield by 5%. It overcomes difficulties of fermentation, like excessive foam formation, excessive heat release, recovery and reuse of bio-catalysts. Our mission is to have a fully functional 150-300 gallon fermenter system operational that takes advantage of the BioEx beads, and if possible to be distilling and producing ethanol for fuel use.

Our major project goals are:

 * Build a fermentation system that is capable of industrial use
 * Fully utilize the advantages of the BioEx beads
 * Show significant fermentation time reduction with the use of BioEx beads
 * Create a system that is simple to retrofit to current fermenters
 * Prove that a layered fermentation system is a feasible replacment to traditional designs

Background Research
In a margin environment with high corn prices, relatively low oil prices and stagnant consumer demand for gasoline, the ethanol industry has borne witness to razor thin margins. The crunch has caused everything from slowdowns to temporary full shutdowns as producers wait for prices to even out and attempt to pinpoint where they can squeeze even the smallest of profit increases out of each gallon of fuel they produce. It wasn’t always that way for the ethanol industry. A decade ago, ethanol producers may not have considered that type of incremental changes, but these days, a boost of even half a cent per gallon could make the difference between an operational or idled ethanol plant(Bevill 2012).

MuPor Technologies (MPT) has a patent pending biocatalyst bead technology (BioEx beads) which produces ethanol in a more sustainable way than current fermentation practices. BioEx beads increases ethanol yield from current 88 - 90% to 95% and decreases production time from 36 hours to 6 hours. Increasing the fermentation rate with BioEx beads prevents excessive foam formation, a common problem of fast fermentation requiring expensive anti-foam agents. The results are reduced production costs, increased ethanol yield, and more sustainable production. It overcomes difficulties of fermentation, like excessive foam formation, excessive heat release, recovery and reuse of bio-catalysts.
