Title (EN) METHOD FOR EXTRACTING LIPIDS FROM MICROALGAE
(FR) PROCÉDÉ D'EXTRACTION DE LIPIDES À PARTIR DE MICROALGUES
(KO) 미세조류로부터 지질을 추출하는 방법
Abstract:
(EN) The present invention relates to a method for extracting lipids from microalgae and, more specifically, to a method for extracting lipids from microalgae by adding, into a high shear mixer, a mixture in which 6 to 262 parts by weight of an organic solvent is added on the basis of 100 parts by weight of microalgae. The present invention enables lipids to be effectively extracted, even when a small amount of solvent is used, and energy consumption to be substantially reduced. In addition, lipids are smoothly recovered since no emulsion is produced during the extraction process, and since the biomass, from which lipids have been removed, and the organic solvent are separated by gravity, the recovery of an organic solvent is simple.
(FR) La présente invention concerne un procédé d'extraction de lipides à partir de microalgues et, plus spécifiquement, un procédé d'extraction de lipides à partir de microalgues par ajout, dans un mélangeur à cisaillement élevé, d'un mélange dans lequel 6 à 262 parts en masse d'un solvant organique sont ajoutées sur la base de 100 parts en masse de microalgues. La présente invention permet d'extraire efficacement des lipides, même lorsqu'une petite quantité de solvant est utilisée, et de réduire sensiblement la consommation d'énergie. De plus, les lipides sont récupérés sans à-coups étant donné qu'aucune émulsion n'est produite pendant le processus d'extraction, et étant donné que la biomasse, à partir de laquelle des lipides ont été éliminés, et le solvant organique sont séparés par gravité, la récupération d'un solvant organique est simple.
(KO) 본 발명의 미세조류에서 지질을 추출하는 방법에 관한 것으로, 더욱 자세하게는 미세조류 100 중량부에 대하여 6~262 중량부의 유기용매를 첨가한 혼합물을 하이쉬어믹서(High shear mixer)에 투여하여 미세조류에서 지질을 추출하는 방법에 관한 것이다. 본 발명은 적은 용매의 사용으로도 지질을 효과적으로 추출하고, 에너지 사용량을 상당히 감소시킬 수 있으며, 상기 추출과정에서 에멜젼이 생성되지 않아 지질 회수가 원활하며, 지질이 제거된 바이오매스와 유기용매가 중력에 의해 분리되어 유기용매의 회수도 용이하다.
