  • Can extrusion-expelled soybean be used as a protein source for human consumption?
  • Soybean is generally recognized as a source of edible and industrial oil, and the deoiled meal is seen as a source of protein in animal feed. In recent years, however, more interest has been directed toward using soy meal as a protein source for human consumption. Extrusion-expelling of soybean provides an opportunity in this direction.
  • What is a screw press expeller?
  • The expellers (named after the first screw press founded by Anderson in 1902) are the screw presses most often encountered in the industry. They consist of a screw rotating in a horizontal perforated barrel formed by regularly spaced metal bars (this space can vary from 0.5 to 0.1 mm); the oil flows along the barrel.
  • 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 industrial pressing of oilseeds?
  • Industrial pressing of oilseeds is realized using continuous screw presses. The presses are fed with crude or pre-treated seeds. Types of pre-treatments (thermal pre-treatment, size reduction, mechanical sieving, etc.) differ for various seed species (Carr 1997). Each type of seed pre-treatment provides its own advantages.
  • What is oil extraction process?
  • Generally, the oil extraction is based on two main steps: pressing (solid¨Cliquid expression) and solvent extraction. Mechanical and thermal pre-treatments preceded these processes and contribute to enhance their performances. Depending on the seed species, the oil recovery processes can vary.
  • Does unidirectional hydraulic pressing affect continuous oil expression?
  • Discontinuous hydraulic pressing leads to the similar performance changes as continuous screw pressing. Therefore, the unidirectional hydraulic pressing may be a first approach to evaluate the effect of these pre-treatments on the continuous oil expression.
