  • Does screw pressing increase oil yield?
  • Screw pressing of entire seeds leads to higher oil yields (maximum 85.7 % for entire seeds and maximum 72.01 % for dehulled seeds). Behavior according to moisture content is also different; for entire seeds, oil yield decreases with increasing moisture content whereas an optimum oil yield can be found for dehulled seeds.‌
  • 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 screw press is used for canola seeds?
  • The Reinartz AP08 screw press (length 1800 mm, width 500 mm and height 800 mm) was used for this study (Fig. 1). This pilot screw press is Fig. 4, Fig. 5 show the evolution of the press performances (passage time, press capacity, oil yield, and specific energy consumption) versus the screw rotation speed (0–18.2 rpm) using canola seeds.‌
  • Can oil seeds be mechanically expressed in a screw press?
  • This work studies oil seeds mechanical expression in a screw press. For this purpose, a pilot-scale screw press (0–40 kg/h) was instrumented by installing sixteen pressure sensors and three temperature probes throughout the screw. Canola ( Brassica napus L) and flax ( Linum usitatissimum) seeds were used for investigation.‌
  • Can a screw press extract oil?
  • The oil extraction by a screw press (mechanical press) has been conducted using different oilseeds to obtain the yield of oil by several researchers (Bogaert et al., 2018a; Chouaibi et al., 2019; Petropoulos et al., 2018; Rombaut et al., 2015; Subroto et al., 2015).‌
  • What equipment is used for oil seeds expression?
  • Screw presses are the most prevalent equipment used for oil seeds expression. A screw press consists of an horizontal or vertical screw fitting closely inside a perforated cage (frame) where liquid (oil) is expelled. Both screw and cage are tapered toward the discharge to increase the pressure on the material.
