  • Why is prepress solvent extraction better than sunflower meal?
  • Because sunflower oil has a substantially higher economic value than sunflower meal, process economics improve significantly as the oil recovery yield increases. Therefore, prepress solvent extraction, with the highest oil recovery yield, is the process method utilized today for the majority of the sunflower seed that is crushed globally.
  • What is a prepress solvent extraction method in a sunflower crushing plant?
  • In a typical sunflower crushing plant using the prepress solvent extraction method, the initial steps of seed pre-cleaning and seed drying are located in the seed receiving section of the facility, prior to seed storage.
  • How is sunflower oil extracted?
  • We can increase the surface area by grinding the sunflower seeds into a coarse meal, using mechanised hammer mills. This meal is then heated to aid oil extraction, a process that can sometimes release impurities. These are removed to ensure that the oil is edible. The mixture is then fed into a sunflower oil pressing equipment.
  • How is sunflower crushed for oil recovery?
  • Sunflower is crushed for oil recovery via one of two process methods, hard pressing or prepress solvent extraction. Hard pressing relies upon exerting high pressure on the prepared seed to separate oil from the solids fraction, historically recovering about 25% oil from the seed.
  • What is sunflower seed processing?
  • Sunflower seed processing focuses on sunflower oil as the most valuable product. It is used as high-value oil in various food applications. The deoiled meal is considered a byproduct and is mostly used as animal feed. In 2011, annual world production of deoiled sunflower meal was at 16 million tons (FAO, 2013).
  • What is prepress solvent extraction?
  • Prepress solvent extraction relies on exerting medium pressure on the prepared seed to separate the majority of the oil, followed by solvent extraction to separate additional oil from the solids fraction, recovering over 40% oil from the seed in modern crushing plants.
