  • Can a mechanical oil expeller press be used for small scale oil extraction?
  • A mechanical oil expeller press was designed, constructed & further analyzed with simulation software (ANSYS) in this research work. This expeller can be useful for small scale oil extraction. ASME shaft design code was used in designing the screw shaft of the press. Locally available material (mild steel) was used in manufacturing of the expeller.
  • What is a screw press oil expeller?
  • The document describes the design and fabrication of a small-scale screw press oil expeller. Key features include a feeding hopper, cylindrical casing housing an interrupted screw drum, oil and cake outlets. In operation, the screw drum conveys, crushes and presses oilseeds, extracting oil through perforations.
  • Can screw expeller cater massive Jatropha biomass for oil extraction?
  • This study is aimed to make efficient screw expeller to cater massive Jatropha biomass for its oil extraction. A computational flow dynamics (CFD) simulation is performed to estimate the pressure developed inside the barrel through screw pressing when the feedstock is Jatropha seed.
  • How does a oil expeller work?
  • Locally available material (mild steel) was used in manufacturing of the expeller. A 20 hp 3-phase electric motor was used for running the machine and the rpm of the screw was maintained 140 rpm. A screw rotates inside the barrel of the press which creates pressure for the extraction of oil.
