  • 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%.
  • What is soybean oil extruding-expelling tea model?
  • Flow diagram of soybean oil extruding-expelling TEA model. The extrusion process follows crop handling. Different from typical conventional expelling processes, there was no need for cooking before expelling in the extruding-expelling process. During the extruding process, heat was generated during extruding because of friction among soybeans.
  • Is soybean meal a profitable oil extruding process?
  • Though the oil expelling process is used to produce oil, the soybean meal is actually the driving force for the whole production system. From Figure 8 a, the increasing economic and markets can be also impacted. The extruding-expelling process has positive gross and net profits, indicating this process was profitable.
  • Why is mechanical expelling of soybean meal important?
  • Additionally, higher revenues for expelled soybean meal are the main reasons for higher revenue due to its higher oil content, and thus higher energy content. This is also the reason why the mechanical expelling process still exists for specific feed applications.
  • Is oil removal from soybeans economic?
  • Unfortunately, very few studies have examined the economics of oil removal from soybeans, especially for industry-scale mechanical expelling. This study focused on the extruding-expelling process to produce crude soybean oil (degummed). The objective of this study was to construct a techno-economic simulation model.
  • What is soybean oil?
  • Soybean oil is one of the main products from soy processing operations. It is also one of the main oils used for applications in the food industry and industrial applications, such as such as biodiesel and bio lubricant conversion [ 6, 7 ].
