Oil extraction process
Oil extraction process:
(1) the process of oil extraction classification by mode of operation, the system of oil extraction process can be divided into intermittent and continuous leaching leaching:
① batch leaching parison into the extractor, the cake is discharged from the extractor to extract the solvent and the like into the fresh oil rich mixture operation of the process, are batchwise, intermittently, the leaching process is performed periodically belong to this type of process .
② Continuous leaching parison into the extractor, the cake is discharged from the leaching, solvent extraction and other fresh oil injection and a rich mixture operation of the process, a continuous leaching process is carried out belongs to this type of process. Press contact way, leaching method of oil extraction process can be divided into immersion, spray and hybrid leaching.
③ immersion leaching material embryos soaked in solvent extraction process called complete immersion leaching. Genus immersion leaching equipment pot groups, in addition to the bow, U-shaped and Y-leaching and so on.
④ extraction solvent spray was sprayed state and material embryos were contacted to complete the leaching process is called spray leaching, is a spray-type crawler leaching leaching equipment and so on.
⑤ It is mixed leach leaching way of a combination of immersion and spraying, are mixed with the leaching device and rotocel extractor and loop type extractor and so on.
(2) oil extraction process according to production methods can be divided into pre-press direct leaching and extraction:
① direct leaching direct leaching, also known as "a leach." It is the direct leaching process fuel oil pretreated. This process is suitable for low oil content of oilseed processing.
② pre-press oil leaching leaching pre-press to squeeze out the part of the pre-fat, high oil cake and then make the process of leaching. This process is suitable for a high oil content of oil.
