• 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 seeds can a screw press machine process?
  • Our screw press machines are capable to process a variety of seeds and nuts such as Castor Seeds, Coconut / Copra, Cotton Seeds, Groundnuts / Peanuts / Earthnuts, Sunflower Seeds, Jatropha Seeds, Mustard Seeds / Rapeseeds / Canola Seeds, Neem Seeds, Palm Kernel, Sesame Seeds, Shea Nuts, Soyabean / Soybean, Flax Seeds, Karanja Seeds etc.
  • What is the oil extraction ratio of oil palm screw press?
  • … Plate 1: Side View of the Oil Palm Screw Press (Adetola et al., 2012) Results of performance test showed that the highest oil extraction ratio (OER) of 17.90% and oil extraction efficiency (OEE) of 79.56% were obtained at the sterilization time of 60 min, digestion time of 10 min and screw speed of 10 rpm (Adetola et al., 2012).
  • How does an oil extraction press work?
  • A screw rotates inside the barrel of the press which creates pressure for the extracti on of oil. Raw material is feeded through hopper & compressed inside the barrel for oil extraction and the cake is discharg ed through a choke mechanism outside. The pressure on screw was determined & applied in the created meshed design in Ansys.
  • How to improve the efficiency of oil extraction machine?
  • The efficiency of the machine could be further improved by cutting inner grove of the bars for ease of extracting oil from smaller seeds as rape seed, sesame etc. It is efficient only for small scale production. Failure of screw causes undesirable costs under excess stress and bending deformation.
  • How oil expeller Machine Works?
  • The working principle of the oil expeller machine is to forcefully push the oilseeds and nuts through the barrel by the action of the revolving worm. Due to increased pressure of worms, the oil squeezed out from the seeds and turns out through holes. After pressing, the crude oil and oil cake are obtained.
