Enzymatic and process technologies to increase corn dry grind slurry solids
In conventional dry grind process, high glucose concentrations (>15% w/w) and liquefaction viscosities restrict slurry solids contents to 30 to 32% w/w. High slurry solids fermentations (above 33%) are important in reducing energy costs; decreased water input results in less evaporation, …

Characterization of amylose lipid complexes and their effect on the corn dry grind process
The dry grind process is the most commonly used method for production of corn ethanol. Ethanol from corn is the biggest contributor to bioethanol produced in the US. In this study, effects of different parameters such as liquefaction temperature, solids content and particle size on formation of …

Technical and economic viability of value added product recovery in the corn dry grind ethanol process
Although ethanol is the primary product of the corn dry grind ethanol process, other coproducts in the dry grind process also contribute to sustainability. However, low coproduct value is responsible for high dependence of plant profitability on ethanol revenue. Improving coproduct value and …

Thin Stillage Fractionation to Improve Water Recycling Rates and Heat Transfer Characteristics in the Corn Dry Grind Process
… a continuous microfiltration (MF) system for the corn dry grind process. Total area requirement decreased with number of stages but there was tradeoff between higher capital costs involved at higher number of stages. Optimal system also showed potential to process more than twice the amount of …

Use of treated effluent water in cellulosic ethanol production
… supplies. Current water consumption rate in corn dry grind ethanol plants is 3 to 4 gallons of water per gallon of ethanol produced (gal/gal) and 6 to 10 gal/gal for cellulosic ethanol plants. The main goal of this study was to examine the use of treated wastewater effluent in place of …

Applications of alpha-amylase corn in the dry grind process for fuel ethanol production
Dry grind processing for fuel ethanol production from corn faces obstacles that limit profitability and sustainability. High temperatures required for liquefaction demand large thermal energy inputs and produce slurries with high final viscosities. These viscosity values increase power consumed by …

Effects of corn quality and storage on dry grind ethanol production
Corn dry grind industry is the major contributor of ethanol production in the US. Ethanol plants incur economic losses due to seasonal variations in ethanol yields. Ethanol yields typically are low during the first month after harvest, increase for the next six to seven months and decrease again …

Comparison of fermentation characteristics between colored corn and yellow dent corn using two dry grind process methods
In dry grind ethanol plant, distillers dried grains with solubles (DDGS) is the primary coproduct which is used mainly in ruminant animal diets. Increasing market demand for coproduct in dry grind process is needed. One way is to use corn rich in anthocyanin content as feedstock. Anthocyanin …

Modeling the Fourier transform near infrared spectra of unreacted starch in corn for monitoring applications
The dry grind ethanol process is an important part of the renewable biofuels industry. In this process corn must be stored and used throughout the year. Corn quality changes, in terms of unreacted starch content, in the dry grind process have not been extensively studied, although they impact the …

Characterization of zein extracted from beer solids, a coproduct of dry-grind ethanol
Zein, the prolamine of corn, has been proposed for different food applications: as coating material for flavor encapsulation, in moisture barrier films, as chewing gum base. Most recently, it has been explored in biomedical applications as tissue scaffolding, to enhance cell spreading and …
