  • 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 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.
  • 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 are oil extraction parameters?
  • The aim of this presentation is to study theoretically and experimentally the oil extraction parameters such as velocity of flow, pressure in screw channel and oil flow during oil expelling with a given screw configuration. This type of information will be useful in optimization and control of expeller operation.
  • Does a screw press produce jatropha oil?
  • The influence of different motors speeds of 20, 60, 100 and 140 rpm and preheating temperatures 50, 75, 100 and 125 °C on oil extraction yield were investigated. The results show that extraction Jatropha oil by screw press ismore efficient in producing Jatropha yield than other methods.
