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 …

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 …

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 …

Thin Stillage Fractionation to Improve Water Recycling Rates and Heat Transfer Characteristics in the Corn Dry Grind Process
… 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 thin …

Increasing dry grind ethanol yield through fiber pretreatment after liquefaction
… and fiber in corn grain are 72 and 10% on a dry basis (db), respectively. In the conventional dry grind process, starch is converted to ethanol; whereas, corn fiber remains unconverted. Corn fiber contains 12 to 18% cellulose and 11 to 23% starch which can be hydrolyzed and fermented into …

Technical and economic viability of value added product recovery in the corn dry grind ethanol process
… 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 …

Membrane Processing of Ethanol -Extracted Corn Oil
… (MALDI) mass spectroscopy. Economics of the dry grind process with the new membrane processes for oil recovery were shown to add considerable value.

Engineering economic analysis of the quick-germ/quick-fiber modified dry grind ethanol fractionation process
… of corn-to-ethanol production, several modified dry grind processes had been developed at the lab scale. The Quick-germ / Quick-fiber (QQ) process is one of them. However, there has been no analysis of the QQ process that provides detailed information related to the energy, water, and economic …

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 …

Shelf-Life Improvement of Distillers Wet Grains with Solubles
… a co-product of the ethanol production using the dry-grind process. DWG is widely used as a feed and supplemental protein source in North American cattle rations. However due to its short shelf-life, 3-4 days in the summer and 7-10 days in the winter, its use is limited to cattle feeding …

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, …

Evaluation and modification of processing techniques for recovery of anthocyanins from colored corn
… sensory properties of food and beverages. The processing industry commonly uses artificial food colorants derived from petroleum or coal, called coal tar dyes. These dyes may cause attention-deficit/hyperactivity disorder, genotoxicity, neurotoxicity and/or carcinogenicity. In an era of …

Characteristics of heat transfer fouling of thin stillage using model thin stillage and evaporator concentrates
… in 2012. Corn ethanol was produced primarily by dry grind process. Heat transfer equipment fouling occurs during corn ethanol production and increases the operating expenses of ethanol plants. Following ethanol distillation, unfermentables are centrifuged to separate solids as wet grains and …
