  • 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.
  • How oil-rich seeds can be extracted from a twin-screw system?
  • However, some models have, in the screw end, an extraction zone ensuring the oil extraction. Thus, the oil-rich seeds treatment became feasible since the obtained pellets have oil content in the range of 30?35 % (Johnson 2000 ). The twin-screw systems are mainly extruders whose use began to grow.
  • Who invented the screw press?
  • The first screw press was invented by Anderson in 1902 and was steadily improved since. Generally, the screw press contains a helical screw rotating in a barrel. The seeds are driven by the screw; the barrel ensures the progression of the seeds by preventing the cake to “turn en mass”.
