History, Origin, and Evolution

  • What is oilseed press cake?
  • Oilseed press cake is a major co-product of the extraction of oil from oilseeds. The two traditional methods to extract oil from oilseeds are either using a screw press or using solvents.
  • How are rapeseed seeds extracted?
  • The rapeseeds were milled using a laboratory mill (A11 basic, IKA, Germany) and sieved into 1 mm fractions. The obtained fraction of seed material (about 20 g) was treated with petroleum ether (b.p. 60–90 °C) within 7 h. The extraction of the seed oil was done in triplicate. The oil content of the seeds was 40.9 ±â€‰0.1%.
  • How is rapeseed pressed?
  • In the same study, rapeseed was pressed using a single-screw press operated with two screw speeds, i.e., slow and fast, and two barrel temperatures (nonheated and heated, where resulting cake temperatures were 53 and 60 °C, respectively).
  • 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.
