Artificial Neural Network Modeling Of Ddgs Flowability With Varying Process And Storage Parameters, Rumela Bhadra, K. Muthukumarappan, Kurt A. Rosentrater Aug 2011

Artificial Neural Network Modeling Of Ddgs Flowability With Varying Process And Storage Parameters, Rumela Bhadra, K. Muthukumarappan, Kurt A. Rosentrater

Neural Network (NN) modeling techniques were used to predict flowability behavior of distillers dried grains with solubles (DDGS) prepared with varying condensed distillers soluble (10, 15, and 20%, wb), drying temperature (100, 200, and 300°C), cooling temperature (-12, 0, and 35°C) and cooling time (0 and 1 month) levels. Response variables were selected based on our previous research results, and included aerated bulk density, Hausner Ratio, angle of repose, Total Flowability Index, and Jenike Flow Function. Various neural network models were developed using multiple input variables in order to predict single response variables or multiple response variables simultaneously. The NN …


Effects Of Conditioner Steam, Extruder Water And Screw Speed On Physical Properties Of Ddgs-Based Extrudates In Twin-Screw Extrusion, Parisa Fallahi, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan, Mehmet Tulbek Aug 2011

Effects Of Conditioner Steam, Extruder Water And Screw Speed On Physical Properties Of Ddgs-Based Extrudates In Twin-Screw Extrusion, Parisa Fallahi, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan, Mehmet Tulbek

A fractional factorial design with a replicated central composite point was used to investigate the effects of extrusion processing on physical properties of DDGS–based aquafeeds using a twin screw extruder. Extrusion cooking trials were performed using an ingredient blend for Nile tilapia, with 2 levels of screw speed (350 and 450 rpm), 2 levels of extruder water (0.236 and 0.302 kg/min) and 2 levels of conditioner steam (0.1 and 0.15 kg/min). The central point was 400 rpm screw speed, 0.271 kg/min extruder water, and 0.12 kg/min conditioner steam. Effects of these processing conditions on extrudate characteristics were extensively analyzed, and …


Using Alternative Flours As Partial Replacement In Barbari Bread (Traditional Iranian Bread) Formulation, Shirin Pourafshar, Padmanaban G. Krishnan, Kurt A. Rosentrater Aug 2011

Using Alternative Flours As Partial Replacement In Barbari Bread (Traditional Iranian Bread) Formulation, Shirin Pourafshar, Padmanaban G. Krishnan, Kurt A. Rosentrater

Since cereals and cereal-based products are a cheap source of energy, they are highly consumed in all of countries. Wheat is the major cereal, consumed in different food products, especially bread. Today, whole wheat flour is being consumed in most of the breads because of its nutrient components but still different problems are associated with this flour, such as allergies and loss of nutrient components due to milling and refining. Thus, to find different sources to fortify products made with wheat flour as their major ingredient, especially bread is important. In this study, five different flours (20% of each flour …


Effect Of Starch Sources And Protein Content On Extruded Aquaculture Feed Containing Ddgs, Sankaranandh Kannadhason, Kasiviswanathan Muthukumarappan, Kurt A. Rosentrater Feb 2011

A 3 × 3 × 3 completely randomized design was used to investigate extrusion cooking behavior and product characteristics of distillers dried grains with solubles (DDGS), protein levels, and various starch sources in a laboratory scale single screw extruder. Cassava, corn, and potato starches with varying levels of DDGS (20%, 30%, and 40% wet basis (wb)) were extruded with three different proportions of protein levels (28%, 30%, and 32% wb). The extrusion cooking was performed at a constant feed moisture content of 20% wb, barrel temperature of 120 °C, and a preset screw speed of 130 rpm (13.6 rad/s). Extrudate …
