• How does a Moringa screw press oil expeller work?
  • Schematic view of the moringa screw press oil expeller Schematic exploded view of the moringa screw press oil expeller The seeds are introduced into the machine through the roasting drum where they are heated. Thereafter, the seeds flow down to the feed hopper through a sliding gate provided on the roasting drum.
  • How to predict flow velocity and pressure in screw-press oil expeller?
  • The flow velocity and pressure was predicted using an analytical solution of an isothermal Newtonian flow in finite screw channel. An innovative design of continuous spiral screw was developed for screw-press oil expeller.
  • What is a screw press oil expeller?
  • The conventional screw press oil expellers are made of 4-8 set of screw sleeves with different pitch in reducing order and mounted on shaft. The spacers are provided in between two screw sleeve and the two flight uniform.
  • What is a continuous spiral screw for oil expeller?
  • An innovative design of continuous spiral screw was developed for screw-press oil expeller. The flow velocities in the down channel range from 125 to 175 mm/s through the length of screw from 150 to 500 mm for the screw drive of 48 rpm. The maximum pressure was built at the end of screw in the range of 9 – 10.57 x 105 Pa.
  • 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.
  • 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.
