What We Do


Cereal Process Technologies is a Limited Liability Company managed by seasoned professionals in the agricultural processing and corn milling industries. CPT holds the license to the patented technology used in those processes.

Mr. R. James Giguere invented the corn dry-fractionation technology CPT employs in its milling process. He continues to hold the original patents for his innovation. A chemical engineer, Mr. Giguere’s career spans more than fifty years in wet and dry corn milling for food and industrial markets and in ethanol processing. Although retired, Mr. Giguere remains active in the company. His process and design innovations continue to advance corn dry-milling technologies.

CPT's dry corn fractionation technology has been used for more than 3 decades to produce ingredients for the beverage, alcohol and snack foods industries and petroleum drilling fluids, making it the most proven fractionation technology in the industry.

The CPT process is simple, yet elegant.  Infinite turn-down capability and process flexibility make it the perfect technology for an industry looking for new ways to enhance the bottom line.

Five corn milling and processing plants currently use the CPT technology for food, industrial and ethanol purposes. They include the world’s largest corn dry mill, Valero’s ethanol plant in Jefferson, Wisconsin. Constructed in 2007, this plant has continually produced higher value products even in thin margin environments. The newest CPT facility is the Pilot Plant located at the National Corn to Ethanol Research Center in Edwardsville, Illinois. 

This pilot plant, provided by CPT to NCERC, allows cutting edge research in concentrated starch, enhanced bran for cellulosic opportunities and other value-added research projects.  CPT is also in the process of constructing a large-scale milling facility in Iowa targeted for completion in early 2014.

All of these facilities chose CPT technology because of its proven ability to effectively separate each of the corn kernel’s key constituents: endosperm, germ (oil) and bran. CPT’s fractionation system delivers a much purer starch stream called "Degermed Debranned Corn" (DDC), which significantly improves the efficiency at the ethanol plant. At the same time, dry fractionation enables the ethanol plant to capture significantly higher value from the corn by entering newer, and growing, markets . The technology unleashes the capability to extract 1.2 to 1.4 pounds of pure corn oil per bushel for use in edible or biodiesel markets. Bran, or fiber, can be used for feed, thermal energy and cellulosic ethanol.

High protein DDG replaces DDGS with much higher value and the ability to increase the usage in monogastric animal diets such as swine, poultry and fish.  Commercial research is also being conducted to optimize biobutanol with fractionation and other confidential applications that hold tremendous promise.
