• What is an oil expeller press?
  • French custom designs, manufactures and supports oilseed preparation equipment and screw presses, sometimes referred to as oil expeller presses. These oil extraction machines gather vegetable oil from oil-bearing seeds and nuts for food and industrial uses, including biodiesel and other fuels.
  • Who invented linseed oil extraction machines?
  • Alfred W. French Sr. founded French in 1900 to produce state-of-the-art equipment for the extraction of linseed oil from flax. Mr. French soon adapted his equipment to other oilseeds as well. Today, French stands as a leading supplier and innovator of oil extraction machines and mechanical oilseed screw presses.
  • 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 is cold press oil processing?
  • Cold press oil processing is a method where heat exposure is minimized to offer the highest recovery of oil in a single pass. In oilseed processing, the primary goal is to extract as much oil as possible from the seed while consuming as little energy as possible. The result is two end products: oil and the leftover solids, traditionally called meal.
  • What is industrial pressing of oilseeds?
  • Industrial pressing of oilseeds is realized using continuous screw presses. The presses are fed with crude or pre-treated seeds. Types of pre-treatments (thermal pre-treatment, size reduction, mechanical sieving, etc.) differ for various seed species (Carr 1997). Each type of seed pre-treatment provides its own advantages.
  • Who is French oil extraction machine & screw presses?
  • Today, French stands as a leading supplier and innovator of oil extraction machines and mechanical oilseed screw presses. French has provided thousands of roller mill and mechanical screw presses around the world, processing all major oilseeds with customers in more than 80 countries.
