• What is an oil extraction machine?
  • This machine is commonly used in commercial or industrial where there is a need for large-scale oil production. They are engineered to efficiently process significant quantities of oilseeds or nuts, ensuring high productivity and optimal oil extraction yields.
  • 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.
  • What happens during screw expeller processing of palm kernel seeds?
  • Heat transfer between the pressing chamber and the oil and oilcake streams during screw expeller processing of palm kernel seeds. Journal of Food Engineering, 31 (1), 1¨C7. Omobuwajo, T. O., Ige, M. T., & Ajayi, A. O. (1998). Theoretical prediction of extrusion pressure and oil flow rate during screw expeller processing of palm kernel seeds.
  • 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).
  • Who invented the oil expeller?
  • The name of the expeller and the expelling process go back to an invention of Anderson International Corp. It has been patented by Mr. Anderson and protected by the corresponding trademark. Through early licensee agreements the expeller soon became the standard machine in the modern oil milling industry worldwide.
  • What is a seed expander?
  • Expanders are closed extruders, where the seeds are crushed but without oil extraction. The screw is locked in a closed system in which nozzles are regularly made to enable water or steam injection. This mode of seed crushing can be considered as a seed preparation before a second, mechanical or solvent extraction step.
