  • How is soybean processed?
  • Modern soybean processing starts with solvent extraction to obtain crude oil and defatted meal. Most defatted meal is used for animal feed and only a small portion is further processed into different types of soy protein products for human consumption (see Chapter 8). Crude oil contains variable amounts of nontriglyceride materials.
  • Can two-stage extruding-expelling process improve soybean oil yield?
  • 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%.
  • How is oil extracted from soy flakes?
  • During solvent extraction oil is removed from the soy flakes by an organic solvent to form an oil/solvent mixture called a miscella. The oil is recovered from the miscella by removing the solvent by steam stripping. Most commercial oil extraction is currently by hexane extraction, but other solvents have been considered.
  • How hexane is used to extract soybean oil?
  • However, efforts have been made to reduce the costs (Reverchon and Osseo 1994). Solvent extraction of soybeans is a diffusion process in which the solvent (hexane) selectively dissolves miscible oil components. During extraction, hexane solubi lizes soy oil from cotyledon lipid bodies in soy flakes rapidly, as soon as it enters the lipid body.
  • What are the sources of wastewater from soy oil processing?
  • 1. Wastewater Control The sources of wastewater from soy oil processing are (I) process wastewater, which has been in contact with oil, (2) noncontact cooling water that is uncontami nated because it has been circulated in pipes, and (3) rainwater runoff, which may have been in contact with contaminated areas (Smallwood 1995).
  • How many tons a day does a soybean extraction plant remove?
  • In addition, for grade 2 soybeans, which may contain up to 2% foreign matter, an extraction plant processing 1000 tons daily will remove as much as 20 tons of trash (Snyder and Kwon 1987). Moore (1983) described the cleaning apparatus used to separate foreign materi als (Fig. 6.2). Soybeans are distributed over a two-deck screen sizer.
