Seed Oil Extraction Hydraulic Press Machine in Ethiopia

  • What is oil extraction process?
  • Generally, the oil extraction is based on two main steps: pressing (solid–liquid 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.
  • 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).
  • 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 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–liquid expression) and solvent extraction.
