Center for Crops Utilization Research
In the 1980s a crisis existed in American farming—a crisis of overproduction, underutilization, and decreasing international market share for raw commodities. Also, the United States’ growing dependence on imported oil and long-term forecasts for increasing oil prices put America at risk. To address this crisis, Center for Crops Utilization Research (CCUR) was established in 1984 through a special appropriation from the Iowa legislature. The center was tasked to respond to the urgent need to improve America’s agricultural competitiveness. Four decades later, there are new opportunities to increase demand for Iowa’s crops. Consumer demand is increasing for new healthful food ingredients, biobased alternatives to petroleum-based products, and sustainable and environmentally friendly industrial processes. The rapid advancement of new food processing technologies and industrial biotechnology enable those demands to be met in an economically viable way. While CCUR’s core mission of increasing demand for Iowa crops remains relevant, the center is also taking these opportunities to grow our connection with companies and entrepreneurs to help them to test, troubleshoot, and optimize their ideas in an industrial-friendly setting.
Organizational Unit
Agricultural and Biosystems Engineering

Since 1905, the Department of Agricultural Engineering, now the Department of Agricultural and Biosystems Engineering (ABE), has been a leader in providing engineering solutions to agricultural problems in the United States and the world. The department’s original mission was to mechanize agriculture. That mission has evolved to encompass a global view of the entire food production system–the wise management of natural resources in the production, processing, storage, handling, and use of food fiber and other biological products.

History
In 1905 Agricultural Engineering was recognized as a subdivision of the Department of Agronomy, and in 1907 it was recognized as a unique department. It was renamed the Department of Agricultural and Biosystems Engineering in 1990. The department merged with the Department of Industrial Education and Technology in 2004.

Abstract

Mechanical expelling (pressing) is a common and developed technique used to separate soybean oil from soybean protein and fiber. Due to the relatively higher oil content in the expelled meal compared to solvent-extracted soybean meal, the mechanical process is often used for specific purposes in industry, such as targeted livestock feed applications. For improving oil recovery and profits, two-stage mechanical process combining extrusion before the expelling process has been introduced and adapted by industrial applications. To examine the viability of this improved two-stage extruding-expelling process, techno-economic analysis was performed by using SuperPro Designer for simulation of the soybean extruding-expelling process. Soybean oil yield increases to over 70% compared to the conventional single-step expelling process with 60%. Soybean oil and soybean meal contributed about 25% and 75% of total revenues, respectively. Through fluctuations in economic conditions, soybean meal plays an important role in earning profits, making the whole mechanical process profitable. According to the sensitivity analysis, the sale of soybean meal is one of the driving forces for the mechanical expelling process, especially in large industrial scales.
