  Enzymatic Steeping Process for Corn Wet Milling (Research Abstract)
Development of a new enzymatic corn wet-milling steeping process that will reduce the steep time, reduce SO2 emissions, lower the capital and operating cost and enhance the quality and yield of products.
  Enzyme-Based Technologies for Milling Grains and Producing Biobased Products and Fuels (Research Abstract)
The objective is to develop new, cost effective, alternative methods and engineering processes for corn processing and fractionation using enzymes, immobilized enzymes and other environmentally sustainable processes.
  Free Tryptophan in Wheat Grain and Milling Fractions
Abstract from a research project exploring free amino acids in whole wheat or milling fractions. The analysis used cultivars of Scout 66 and Trego grown near Bushland, Texas in 2002. There is a link to the full article.
  Grain Milling (Botswana)
Describes a project to develop and manufacture small village-style decorticators to test the performance and economic feasibility of small sorghym-milling systems in Botswana. The project also examined the acceptance of these mills by the village communities and their influence upon sorghum demand and use. The project began in June 1978 and was completed in August 1980.
  Impact of nutrition on the gluten composition and processing quality of wheat (PhD)
Order information and summary of the reseach project. The summary includes a restatement of the problem, the project aims, the approach and the benefits to the industry.
  Improved Handling and Storage Systems for Grain Quality Maintenance and Measurement
This project has 4 objectives. 1. Measure grain commingling levels during elevator handling for use in developing procedures, decision support systems, and instrumentation to facilitate value-added and identity-preserved grain segregation operations. 2. Develop new stored grain packing factors with known accuracy as needed for common grains in trade over a range of field conditions. 3. Develop improved aeration, monitoring, and sanitation systems and best management practices for quality maintenance and insect control in stored grain. 4. Measure dust emission, particle-size distribution, and air entrainment during grain unloading to facilitate reducing dust emissions from grain handling operations and equipment. The project ends 2011.
  Improved Handling of Grain in Commercial Elevators
The specific goals of the expanded research are to: 1. Develop two-dimensional mechanistic models of grain commingling in lab-scale and full-scale bucket elevator boots. Appropriate modeling methods have been identified┐the discreet element method will be used┐and needed grain physical properties have been tabulated from the literature. 2. Determine the effect of repeated handling on particle size distribution of dust emissions from corn and wheat during elevator handling. Experimental protocols were developed during testing with feed pellet handling that can be applied to measurements with wheat and corn. There are links to annual reports from 2005 through 2008. The project is scheduled to end in 2010.
  Increased grain milling efficiency through improved wear resistance rolls
A synopsis of a project conducted at Purdue University to better understand the flaking process in the soybean crushing industry.
  Modeling thermal effects on biomaterials properties
A synopsis of a research project conducted at Purdue University that studies the effects of a given level of heat and moisture application on the conditioning and flaking of soybean particles during milling. The subsequent results are used to improve the production of soybean meal, oil and byproducts.
  Physical and Chemical Properties of Shelled Corn Related to Conditioning, Drying, and Processing
The objectives of this research project are to develop basic knowledge and understanding of the relationships between processing characteristics and the physical properties and chemical properties of shelled corn. There is a link to the 2008 annual report. The project ends in 2010
  Post Harvest Grain Quality & Stored Product Protection Program
Informs about events and news about the program, which is a cooperative effort of Purdue University's Cooperative Extension Service, and the Departments of Agricultural & Biological Engineering, Entomology, and Botany & Plant Pathology.
  Relationships Between Sorghum Grain Attributes, Milling Quality and Flour Quality/functionality
The objectives of this research are: (1) Optimize a milling procedure for sorghum to produce high quality flour, (2) characterize milling fractions of sorghum produce by various milling procedures, and (3) relate physical attributes of sorghum grain to milling performance. The project ends in 2013
  Skcs Uniformity Measures Relating to the Laboratory and Commercial Milling of Wheat (Research Project Abstract)
Research to determine the impact of HRW kernel size variability on laboratory and commercial mill performance. Develop a single kernel hardness reference method that can also serve as a reference method for the SKCS 4100. This will answer questions regarding hardness measurements of hard and soft white wheat, define the measurement error attributed to the SKCS 4100 when measuring hardness, and improve the SKCS calibrations. Research began September 29, 2003; will end Sept. 28, 2008.
  Canadian Grain Commission/Commission canadienne des grains
Information on all Canadian grain, pulse and oilseeds commodities, how grain is handled, grade standards, issues regarding the Canadian grain industry, and, information on the GRL (list of publications, texts of conference presentations, etc.). Has links to many other sites and Canadian organizations.
  Nebraska Wheat Quality Lab
Assists both wheat producers and consumers by developing wheat varieties with quality characteristics that are desired by the wheat processing industry. Founded in 1959, the Lab works with wheat breeders, geneticists, and plant pathologists from the University of Nebraska and USDA-ARS to develop improved wheat varieties for farmers. The Lab uses predictive tests to estimate the end-use quality properties of wheat lines. These tests include milling, protein quality, bread baking, and noodle processing.
  USDA ARS Engineering Research Unit
Researches current problems associated with post-harvest grain conditioning, handling, storage & quality assessments that affect the safety of our food & feed chain. Laboratory, pilot & full scale grain equipment & storage facilities are used to develop new technologies for facility management, maintenance of grain quality, objective assessment of grain quality & reducing grain losses in market channels. The research addresses problems in grain storage, grain flow, grain dust control, wheat hardness testing, wheat milling, dough mixing & digital image analysis for grain inspection.
