• What is an expeller press?
  • An expeller press is a screw-type machine that mainly presses oil seeds through a caged barrel-like cavity. Some other materials used with an expeller press include meat by-products, synthetic rubber and animal feeds. Raw materials enter one side of the press and waste products exit the other side.
  • What is expeller pressed soybean meal?
  • Expeller-pressed soybean meal is sustainably-produced, chemical-free soybean meal. In the past, some soybean producers had to transport their harvest hundreds of miles to reach feed mills and soybean crush plants for processing. Anderson International Corp provides a solution with their expeller-pressed soybean meal.
  • How does a pilot expeller press affect linseed oil yield?
  • When using a pilot expeller press designed for cold pressing, increasing rotation from 1.2 to 18 rpm increased press capacity from 2.2 kg seed/h to 29.4 seed/h, while decreasing canola oil yields from 91 to 84% . Additionally, the number of presses was shown to affect the oil yield and the quality of linseed oil.
  • Why do we need improved cultivars for vegetable oil extraction?
  • Limited land availability and growing demands for vegetable oils call for the development of improved cultivars for harnessing higher yields as well as more efficient oil extraction technologies to augment oil recovery from different oilseed crops without compromising with the oil quality.
  • When did expeller presses start?
  • The earliest expeller presses utilized a continuous screw design. The compression screws were much like the screws of a screw conveyor ¡ªthat is, the helicoid flighting started at one end and ended at the other. Valerius Anderson invented the interrupted screw design and patented it in the year 1900.
