  • Is continuous mechanical pressing the best technology for vegetable oil extraction?
  • Among the physical processes for the extraction of vegetable oils, the continuous mechanical pressing emerges as the best technology to serve small farmers. That ́s because this type of equipment associates both small scale and low cost when compared to the other methods cited.
  • How to optimize a continuous mechanical press?
  • Optimization of the continuous mechanical pressing consist of defining the optimum parameters, such as temperature and moisture content of grain, or adjustments on the press, in order to reach optimum yields of oil, using a minimum value of pressure applied by the press.
  • What is a closed-type oil press?
  • Closed-type presses: in this type, the oilseed is enclosed by a strong perforated steel cage that can apply much more pressure than an open press. Removing oil from the interior of the grain is attained by the pressure applied by a piston placed close to the cage and hydraulically operated.
  • What temperature should a peanut oil press be heated to?
  • As the heating step is costly, it is recommended to heat the grains at lower temperatures, between 40 and 50 oC. The moisture content which favored the press, without contaminating the oil with water, is within the range of peanut commercialization (8 and 12 % wb), thus not requiring any step prior to pressing, such as drying.
  • Does shaft screw press speed affect oil yield?
  • A minimum express efficiency, 33.6 %, was obtained at 10 MPa compressive stress, 150 kg/h feed rate and 50 rpm of shaft screw press speed. For the studied range, oil yield increases with increase in speed of shaft screw press and in feeding rate.
  • Does shaft screw press affect Palm kernel oil yield?
  • The effects of compressive stress, feeding rate and speed of shaft screw press on palm kernel oil yield were evaluated by Akinoso et al. (2009). They used an expeller with a rated capacity of 180 kg/h.
