Characteristics of heat transfer fouling of thin stillage using model thin stillage and evaporator concentrates
… solids as wet grains and liquid fraction as thin stillage. Evaporator fouling occurs during thin stillage concentration to syrup and decreases evaporator performance. Evaporators need to be shutdown to clean the deposits from the evaporator surfaces. Scheduled and unscheduled evaporator shutdowns …

Effects of compositional variables on fouling behavior of thin stillage
… remaining nonfermentable material known as whole stillage is centrifuged to produce two processing streams; wet cake (30 to 35% solids) and thin stillage (5 to 10% solids). Thin stillage is concentrated to 25 to 30% solids in multi effect evaporators. The presence of fouling in evaporators can …

Effects of nitrogenous substances on heat transfer fouling using model thin stillage fluids
… corn ethanol industry, fouling occurs when thin stillage is concentrated into condensed distillers solubles. Several researchers have investigated operating conditions and constituents’ influence on fouling characteristics. However, understanding protein effects on fouling is limited despite its …

Analysis of Heat Transfer Fouling by Thin Stillage From Dry Grind Corn Processing Facilities
… adjust pH and Reynolds number on fouling by thin stillage from a commercial dry grind corn (DGC) process used to produce ethanol from corn. Thin stillage is a DGC process stream consisting primarily of unfermented dissolved solids that are concentrated by evaporators to produce an animal food. …

Effects of temperature conditions and heat treatment within a multiple effect evaporator on thin stillage fouling characteristics
… industry, evaporator fouling occurs when thin stillage is concentrated. Fouling affects the efficiency and environmental footprint of more than 200 biorefineries in the US. Thin stillage is the liquid fraction of unfermented materials from fermentation and is composed of carbohydrate, protein, …

Integrated anaerobic digestion and electrodialysis process model for enhanced volatile fatty acids recovery from thin stillage
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2027-05-01

Comparison Study Between Post-Fermentation Stillage and Pre-Fermentation Mash Utilizing Acidification and Steam Explosion Techniques for Cellulose Saccharification
… mash fiber and post-distillation stillage fiber were examined and compared using a variety of preparatory techniques to determine the better source for cellulose fiber saccharification. Once screened, dried, and diluted to a 10% solution, mash fiber and stillage fiber were exposed …

Thin Stillage Fractionation to Improve Water Recycling Rates and Heat Transfer Characteristics in the Corn Dry Grind Process
… to process more than twice the amount of thin stillage compared to quadruple effect evaporator system for given conditions.

Evaluating the potential of phosphorous recovery from wet milling and dry grind corn facilities using chemical precipitation
… such as light steep water (wet milling) and thin stillage (dry milling), contain phosphorus concentrations that are several orders of magnitude greater than wastewater, potentially enabling cost effective recovery, yet precipitation of phytate in these side streams is poorly understood. Lab-scale …

Enzymatic Enhancement of Water Removal In the Dry Grind Corn to Ethanol Process
… reductions in water-binding capacity of whole stillage were found for two, commercially available, cell wall degrading enzymes, GC220 and MGC. The addition of a protease, GC106, during fermentation was found to significantly enhance ethanol production rates as well as reduce the water binding …

Decontamination and Valorisation of a Corn-to-Ethanol Biofuel Waste Stream
… (TWS) produced during a corn-to-ethanol whole stillage upgrading process. Rheological analysis revealed that TWS exhibits non-Newtonian, pseudoplastic behaviour driven by interaction between fibrous solids and oil-based components, rather than by soluble components such as glycerol. Chemical …

Production of biofuels in a circular cascading bio-based energy system
… cost-effective pyrochar) to digestion of thin stillage which was under stress due to an acidic shock, to investigate the potential role in improving the stability of the AD process. Results showed that the addition of graphene could help stabilize AD of thin stillage after acidic shock, …

Nutritional evaluation of novel ethanol co-products for poultry
… protein and yeast fraction from ethanol stillage (Still Pro™, Fluid Quip Process Technologies, Cedar Rapids, IA). The original raw materials for the FWDDGS consisted mainly of, mashed potatoes, sweet corn, and white bread. The results of the rooster assays indicated that the digestibility …

Optimisation of distillery co-products for poultry feed
… the process confirmed the variability of the stillage, but highlighted the viability of the process for ameliorating some of these differences. Inter-batch variability was reduced from 10% to 1.2% in terms of protein content but dry matter content still varied by more than 8%, due to fibre …
