Corn wet-milling is a process where components of corn kernels are extracted to produce a highly purified product. Most of the products from this process are valuable and mainly required by the food industry. Through this process, every part of the corn is useful to produce the quality ingredients.
The work being done under this agreement is a joint effort to lower the overall processing costs for wet milling and improve the economics of fuel ethanol through the development of enzymatic processing technology. Under this project, a small plant trial (200 Metric Tons per day) of the enzymatic wet milling process (E-Milling) will be done.
The steeping and steepwater evaporation are the two most capital and energy intensive processes in a corn wet milling operation, which limit new plant construction and production expansion. This project will explore a new technology that utilizes the combination of high intensity ultrasound and protease treatment to purify starch from corn.

The wet mill of a corn plant refers to area where the corn is separated into its individual components of starch, gluten, fiber, and germ. The separations in the wet mill are mostly physical through grindmills, screens, cyclones, centrifuges, presses, and filters. The main product of the wet mill is a relatively pure starch stream, either dried ...
May 15, 2003· It is the idea to carry out a cleaning of the starch with an effective amount of an acidic protease after the starch-gluten centrifugation but before the hydrocyclones, in the wet milling process. At this stage up to about 500 ppm free sulphur dioxide may be present in the starch fraction to be cleaned, and pH is 4-4.5.
There is disclosed a continuous process for refining whole grain wheat to obtain a prime wheat starch fraction and an animal feed product, the process comprising dry milling wheat kernels to provide an endosperm fraction, a germ fraction, a fiber (bran) fraction and a cleanings fraction, wet milling the endosperm fraction to provide a mill starch slurry, removing fine fiber tailings from the ...
Jul 21, 2017· J. Nagle has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

The present invention relates to an improved process of treating crop kernels, comprising soaking the kernels in water for 1-12 hours, wet milling the soaked kernels and treating the kernels with one or more enzymes including an acidic protease.
Jan 21, 2009· Enzymatic corn wet milling (E-milling) is a process derived from conventional wet milling for the recovery and purification of starch and co-products using proteases to eliminate the need for sulfites and decrease the steeping time. In 2006, the total starch production in USA by conventional wet milling equaled 23 billion kilograms, including modified starches and starches used for .
Corn wet milling and dry milling are the predominant methods of processing and each method produces distinct co-products. The Corn Wet-Milling Process. The Corn wet-milling process is designed to extract the highest use and value from each component of the corn kernel. The process begins with the corn kernels being soaked in large tanks called ...

Use of enzymes to reduce steep time and SO2 requirements in a maize wet-milling process (PAT - US2002022252)
Quadro invented the original cone or conical mill in 1976. Though simple in principle, the Comil ® was a revolutionary concept that has since evolved into a global processing standard adopted by market leaders around the world. The Cone Mill is typically used for some of the following common applications: Sizing wet granulated particles before ...

REPULPING DIFFICULTIES WITH WET-STRENGTHENED PAPER. Flakes of poorly dispersed paper often plague papermaking operations that have to deal with repulping of wet-strength paper, whether it consists of broke from their own process or whether it arrives at the mill as waste paper.
Sep 28, 2017· More recently, "enzymatic milling", a modified wet-milling process that uses proteases to significantly reduce the total processing time during corn wet milling and eliminates the need for sulfur dioxide as a processing agent, has been developed. Johnston et al., Cereal Chem, 81, p. 626-632 (2004).
