  1. Analytical Tools For Corn Fractionation Roger Ginder Darren Jarboe Iowa State University

  2. Project Overview • Evaluate the economic benefits of corn pretreatment for the dry grind ethanol process using an ethanol processing plant simulation model • Compare simulated returns from using whole grain as a feedstock to returns from using de-germed corn as the feedstock • One project among a group of related projects that will evaluate other fractionation issues

  3. Value of the Project - Near Term • Potential benefits to ethanol industry • Potential benefits to biodiesel industry • Better utilization of value in the corn

  4. How the Project Fits with Dry Mill Ethanol • Has potential to improve the quality of DDGS • Reduced fiber content for some DDGS uses • Increased protein content • Makes corn more competitive with alternative ethanol feedstocks

  5. How the Project Fits with Dry Mill Ethanol • Reduces quantity of a co-product (DDGS) that is becoming plentiful and may be in excess supply going forward • Has potential to increase efficiency of ethanol plants • Increased ethanol per gallon of plant capacity • Better utilization of the primary Iowa feedstock (corn)

  6. Other Related Projects • Specialty Corn with Trait in Germ Portion Approved for Food Uses • Specialty Corn with Trait in Germ Portion NOT Approved for Food Uses • Recapture of Corn Oil After Fermentation For Feed and Industrial Uses

  8. Deliverables For IGQI Portion • Provide a working paper that describes and evaluates the ethanol value chain and the first stage of the value chain for corn products located in the germ. • Develop analytical data and tools to assist producers in evaluating the financial viability of using de-germing prior to dry milling as part of the corn processing value chain.

  9. Progress On IGQI Portion of the Project • Developed Basic Ethanol Model • Currently Building the De-germing Model • Have Obtained Data Necessary to Evaluate Quick Germ Process • Good Progress on Quick Germ Model Development • Attempting to Obtain Cost Data on Mechanical De-germing (Commercial Scale) • Not Currently Operational On Plant Scale

  10. Issues Encountered • Operating Cost Data From Firms Experimenting With De-germing Difficult to Obtain • Most Efforts Are Experimental • Few Firms Are Involved • Data Considered Proprietary • Confidentiality Agreements Have Frequently Been Signed By Plants

  11. Issues Encountered • Favorable Ethanol Prices Have Skewed Industry Interest Toward Investment in Plant Capacity Rather Than Refining Processes • Plant Expansions • Additional Plants • Marketing and Transportation Infrastructure
