Abstract

This project recommends a design for a soy processing facility to produce soy protein concentrates (SPC), soy oil and soy molasses from dehulled soybeans. Utilities were minimized, wherever possible by evaluating whether streams within the system had the capacity to heat or cool other processes. The plant has a production capacity of 170 MM lb soy protein concentrate/year and will be located in Decatur, IL. The proposed design also yields 114 MM lb soy oil/year and 62 MM lb soy molasses/year. The SPC, soy oil and soy molasses have less than 2 PPM residual solvent concentrations and comply with FDA regulations. The plant is running with an uptime of 80% and economic analysis shows an estimated IRR of 41% with an ROI of 59%.
