  • How does an expeller press work?
  • Expeller pressing is based on the principle of applying pressure and friction to the raw materials to squeeze out the oil. An expeller press is a screw-type machine that consists of a barrel, a screw, a hopper, a motor and an outlet. The raw materials are fed into the hopper and then conveyed into the barrel by the screw.
  • Does continuous screw pressing reduce oil yield?
  • For the flaxseed containing 6¨C10 % of water, the oil yield obtained by continuous screw pressing is reduced (Zheng et al. 2003 ), while it is stagnated for the flaxseed containing 7¨C9 % of water (Tostenson et al. 2004 ).
  • What is expeller pressing used for?
  • In the edible oil industry, expeller pressing is used to produce cooking oils, salad oils, margarine, shortening, etc. from various seeds and nuts, such as soybean, canola, sunflower, cottonseed, peanut, castor and flax. In the biodiesel industry, expeller pressing is used to produce biodiesel from vegetable oils or animal fats.
  • Does hydraulic pressing increase oil yield?
  • The oil yield obtained by hydraulic pressing from the flattened seeds is higher than one obtained from the whole seeds (Khan and Hanna 1984 ), while for the dehulled seeds, a lower oil yield is obtained by hydraulic pressing (Singh et al. 1984 ).
