  • 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.
  • 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.
  • 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.
  • Does sunflower oil contain phytosterols?
  • In this study we evaluate the chemical composition of sunflower oils obtained separately by pressing and subsequent solvent extraction from a new seeds rich in phytosterols (IASP-18) and conventional seeds (HA-89). Results have shown that the total content of oil was much lower in the IASP-18 (18.1%) than in the conventional (37.5%) seeds.
  • How is sunflower meal extracted from mineral oil?
  • The solvent vapor stripped from the mineral oil in the mineral oil stripping step is sent to the vacuum condenser for solvent recovery. After the solvent extraction process, an additional increase of the protein content of sunflower meal can be obtained by tail-end dehulling.
  • How to optimize oil extraction from high oleic sunflower seeds?
  • In this study, response surface methodology (RSM) was applied, to optimize oil extraction from high oleic sunflower seeds via EAEP in a prototype automatic continuous stirred-tank extractor. Temperature, enzyme mass, water mass and proton concentration were varied for the exploration of optimum process conditions.
