  • 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 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.
  • 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.
  • Who developed a modified oil expeller?
  • Singh and Bargale (2000) designed and developed a modified oil expeller based on a novel principle of single feed, double stage compression to improve the efficiency of oil recovery. Bamgboye and Adejumo (2008) also developed and modified a screw press for sunflower oil expeller.
