• 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¨C90 ¡ãC) within 7 h. The extraction of the seed oil was done in triplicate. The oil content of the seeds was 40.9?¡À?0.1%.
  • What is rapeseed oil?
  • Rapeseed oil third largest source of edible oil after soya bean oil and Palm Oil. Europe alone contributes six million tons to the world market. The seed is mechanically pressed or pressed to extract 50% to 75% of the Oil content in the seed before sending to solvent extraction to make the process more efficient.
  • Why can’t the solvent extraction plant be processed with flakes?
  • The Solvent Extraction plant can¡¯t be processed with flakes due to its high oil content. The Oil content are to handled with expander with squeezo matic arrangement. Where 20 % of the oil will be drained and collets containing 25% ¨C 28% oil will be transferred for extraction. The collets is with 35% more porosity than the flakes.
  • How much rapeseed oil can be extracted by cold pressing?
  • A nozzle diameter of 10 mm, a screw frequency of 50 Hz, and a press head temperature of 80 ¡ãC ensured the maximum pressed rapeseed oil yield of 26.65% within the applied experimental domain. The crude oil extraction degree achieved by cold pressing was 60.8% of the rapeseed oil yield obtained by the Soxhlet method.
  • How rapeseed oil is extracted by cold pressing compared to Soxhlet Method?
  • The crude oil extraction degree achieved by cold pressing was 60.8% compared to the Soxhlet method. The rapeseed oil contains predominantly oleic, linoleic, linolenic, and palmitic acids, agreeing with other reported rapeseed oils.
  • What is the mass flow rate of pressed rapeseed oil?
  • The temperature of the pressed oil at the exit from the press was 40 ¡ãC. The mass flow rate of the press cake and pressed rapeseed oil under these pressing conditions were 174?¡À?22 g/min and 52.7?¡À?0.1 g/min, respectively. Optimization of screw-pressing process factors can involve the oil recovery yield or quality properties.
