  • Why do oilseeds need to be separated before oil extraction?
  • Most oilseeds need to be separated from their outer husk or shell prior to oil extraction. Dehulling also is referred to as shelling or decorticating. Dehulling increases oil production efficiency, capacity of the extraction equipment and reduces wear in the expeller as the husks are abrasive.
  • How are seeds prepared for oil extraction?
  • Unit operations for preparation of seeds for oil extraction vary slightly depending on the physical properties and oil content (Figure 1). However, most oilseeds go through the process of cleaning, drying dehulling, size reduction, flaking cooking and tempering.
  • How to extract oleaginous seeds without solvent?
  • The oil extraction by mechanical pressing is the most common method for continuous treatment of oleaginous seeds without solvent. Different types of presses can be used depending on the purpose (expeller, expander, and twin-screw extruder) and on the capacity range (3 kg h ?1 to 150 t day ?1).
  • How does seed production affect oil extraction process?
  • The increase in the quantity of seed being slightly lower than the increase in oil production, it demonstrates an improvement of oil extraction processes. Generally, the oil extraction is based on two main steps: pressing (solid¨Cliquid expression) and solvent extraction.
  • What is oil extraction process?
  • Generally, the oil extraction is based on two main steps: pressing (solid¨Cliquid expression) and solvent extraction. Mechanical and thermal pre-treatments preceded these processes and contribute to enhance their performances. Depending on the seed species, the oil recovery processes can vary.
