Definitions

  • the invention relates to a method for pressing a liquid out of a pressed material, in which the pressed material is transported by a screw press along a pressing path and compressed.
  • the invention further relates to a device for pressing a liquid extract from a pressed material, which is designed as a screw press having a movable in a cylinder wall guided screw and the at least one feeder for an extractant and at least one collecting device for the extract connected.
  • Such methods and devices are used, for example, to squeeze oil from oil-bearing crops.
