• Can an expeller press be a hot press or cold press?
  • An expeller press can become a hot press or a cold press, depending on the steps you take upstream before extraction. Equating an expeller with hot pressing isn¡¯t quite accurate because the screw press has nothing to do with the processing temperature.
  • What temperature can an expeller press be used for?
  • In the case of harder nuts (which require higher pressures) the material can exceed temperatures of 120 ¡ãF (49 ¡ãC). 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.
  • How does a plant expeller press work?
  • The process begins with the cleaning and preparation of raw plant materials such as seeds, nuts, and fruits. Once prepped, the material is fed into the expeller press. As the screw rotates, it crushes the plant material and squeezes oil by exerting continuous mechanical pressure.
  • Are all cold pressed oils expeller pressed?
  • All oils that are labeled cold pressed fall under the category of expeller pressed oils. However, it is important to note that the converse is not always true¨Cexpeller pressed oils do not universally qualify as cold pressed oils. As a consequence, cold pressed oils can be categorized as a specialized subset of expeller pressed oils.
  • Are expeller pressed oils more effective?
  • When compared, however, expeller pressed oils may have slightly reduced efficacy as temperatures can go up to 200 degrees Fahrenheit during extraction. While the difference in therapeutic effect is mostly negligible, it may be pronounced if the plant consists of heat-sensitive chemical constituents.
  • Why is expeller pressing so expensive?
  • When expeller pressing, it takes a large number of nuts or seeds to create a high yield ¨C which means more money. This is one of the biggest reasons why oil manufacturers aren¡¯t keen on using this method of extraction and instead use methods that include chemicals and high heat.
