  • Does screw-pressing improve oil extraction performance?
  • By using screw-pressing at pilot plant scale, optimum oil recoveries from walnut, chia, and almond seeds were obtained at 7.5, 10, and 8% (WB) moisture contents, respectively (Martínez et al. 2008, 2012, 2013 ). In each case, the oil extraction performance was also dependent on the pressing temperature and other processing conditions.
  • How to optimize a process for sesame oil extraction by screw-pressing?
  • Ma. Gabriela Bordón, Box-Behnken designs were used to optimize a process for sesame oil extraction by screw-pressing at low temperature (50 °C). Experimental designs included seed moisture content (SMC), pressing speed (PS), and restriction die (RD) as the main processing parameters.
  • Can oil extraction process be scaled to industrial scale?
  • Extractions at pilot plant scale showed a peak in oil recovery (OR, 71.1 ± 2.80%) at 12.3% SMC, 4 mm RD, and 20 rpm PS. Theoretical models were scanned against experimental data in order to scale up the proposed oil extraction process to industrial scale.
  • Which oil extraction conditions have the highest or values?
  • Oil extractions at industrial scale showed maximum OR values (75.8%) under the following conditions: 8% SMC, PS 30 rpm, and RD 10 mm. Furthermore, these conditions gave oils with the lowest FC (4.8%) and quality parameters similar to those obtained at pilot plant scale conditions.
