  • What is screw oil expeller?
  • Screw oil expeller is a mechanical device which can generate pressure from rotation of feed to expeller screw manually or automatically. Screw press method for oil extraction is a mechanical method for extracting oil from raw materials. Extracted oil from screw pressing are used either as a food product or as an industrial product.
  • How does a screw expeller work?
  • In this developed screw expeller, seeds are confined in barrel through a hopper and extraction of the oil is accomplished by exerting sufficient force on confined seed. The residue of the material from which oil has been expressed exits from the unit and is known as the cake.
  • Why is screw shaft important in a screw expeller?
  • Screw shaft is the most vital element of screw expeller as it provides the required amount of pressure for extracting oil from the raw materials. It is evident from this study that, the failure of screw shaft will result into extra costs which is undesirable. In addition, excess stress, bending, displacement may cause major overhaul of the press.
  • Does a screw press machine affect oil yield of N sativa seeds?
  • Deli et al. (2011) studied the effects of physical parameters of a screw press machine on oil yield of N. sativa seeds using a KOMET Screw Oil Expeller. Different nozzle size, extraction speed and diameter of shaft screw were applied in their study.
  • Does kneading temperature affect oil expeller performance?
  • Moses (2014) conducted a performance evaluation test to investigate efficiency of oil expeller machine, the effect of kneading temperature on the oil yield and the extraction losses of the machine.
  • Who developed a screw press for sunflower oil expeller?
  • Bamgboye and Adejumo (2008) also developed and modified a screw press for sunflower oil expeller. Modh and Mevada (2011) designed and made improvement in some components of oil expeller machine and also carried out the thrust ball bearing analysis and results to compare with analytical results.
