  • 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.‌
  • How is rapeseed extracted?
  • 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. The Rapeseeds contain some legume shells, impurities, sand and stones etc. These materials are followed during the harvest at the time of collection.‌
  • Which solvent is used to extract rapeseed oil?
  • It was also interesting to observe that p -cymene, d -limonene and isopropanol were the most effective solvents for oil extraction from the original rapeseed, and p -cymene, isopropanol and n -hexane were more selective. Table 1. Extracted rapeseed oil yields with various solvents. ISO 659-1988.‌
  • 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% – 28% oil will be transferred for extraction. The collets is with 35% more porosity than the flakes.‌
  • What is the process of rapeseed pre pressing?
  • The rapeseed will be used the process of the pre pressing system instead of Expander with squeezo matic arrangements. The Mustard seed can be directly solvent extracted or pressed cake or fully pressed cake. For direct solvent extraction two types of alternative processes are explained in the above.‌
  • How to flake cracked rapeseed?
  • This process will soften the cracked beans make it suitable to good flaking. The Cooked and conditioned cracked rapeseeds are passed through a pair of chilled cast iron rolls fixing specific gap of 0.2mm to 0.35mm to rupture the oil cells where the it will come on the surface and then used to extract with use of solvent.
