Oil Extraction From Identity Preserved Crop Products All-Natural, High-Quality Protein Meal For Animal Feed
West Central, a major agribusiness firm in Iowa, replaced their entire existing facility with a new Dupps screw press operation to produce an all-natural, high quality protein meal from soy beans. The Dupps Company worked with WC for over a year to modify its presses to meet the unique requirements of their patented process. The resulting system allowed WC to provide a consistent sixty percent level of bypass protein -- also known as undegraded intake protein which supplies dairy farmers with a predictable and efficient way to balance rations for their stock.
In the patented WC SoyPlus process, soybeans are comminuted sufficiently to crack the hulls and beans. The comminuted soybeans are then heated in a reactor to a specific temperature range (exact temperature is proprietary) and maintained at elevated temperatures for a specified period (exact time is proprietary). If the time/temperature conditions exceed an optimum level, the nutrient value of the protein within the small intestine of the ruminant animal will be reduced.
After heating, the soy oil is extracted from the beans in a Dupps Oil Seed Pressor, specially engineered for the SoyPlus process. The Dupps Pressor typically processes over 50 tons/day of cracked soybeans, resulting in 5.0% residual oil in the discharge cake. The Dupps Pressor shaft is a proprietary design and is optimized for long service life, low maintenance, and low horsepower usage (under 2 hp/ton/day, raw soybeans).
