Abstract
A separating device for extracting cholesterol from plasma uses a spinner to disperse plasma into an extracting solvent in the form of fine droplets to improve separation efficiency, thereby making it suitable for delipidating blood plasma. Blood plasma is delipidated by providing the plasma to the spinner and dispersing the plasma into the extracting solvent in fine droplets. A de-emulsification step removes residual solvent from the plasma. Blood is removed from an animal and the blood plasma is delipidated. Delipidated plasma is de-emulsified and combined with the animal blood, which is then reintroduced into the animal.
