Patent number: 8828318Abstract: A high pressure extraction apparatus and extracting method therefor are adapted to maintain a medium at the supercritical state to extract substance-to-be-extracted. The apparatus includes an extraction tank, a piston and a control unit. The control unit controls the piston to reciprocate in the extraction tank as well as controls the pressure of the extract space of the tank, feeding of the substance, discharge of extract, and discharge of leftover. Accordingly, the apparatus performs a continuous supercritical extraction.Type: GrantFiled: August 24, 2011Date of Patent: September 9, 2014Assignee: Industrial Technology Research InstituteInventors: Tz-Bang Du, Chyuan Juang, Long-Shuenn Jean, Chen-Hsi Cheng, Hom-Ti Lee, Hsien-Chueh Pi

Patent number: 8591825Abstract: An extraction apparatus capable of continuously and efficiently extracting a biological substance is provided. Multiple rotation discs are utilized in the extraction apparatus to significantly improve the efficiency of extracting the biological substance by using an extraction solvent. Specifically, when the extraction solvent is applied to extract lipids from microalgae, retention time of the microalgae in the extraction solvent can be significantly increased, and solubility of the microalgal lipids in the extraction solvent can be improved. Hence, the efficiency of extracting the lipids from the microalgae by using the extraction solvent can be enhanced. On the other hand, owing to the improvement of the efficiency of extracting the lipids from the microalgae, the amount of the extraction solvent can be reduced, and production costs can be reduced as well.Type: GrantFiled: August 19, 2011Date of Patent: November 26, 2013Assignee: Industrial Technology Research InstituteInventors: Chen-Hsi Cheng, Chung-Cheng Han, Tz-Bang Du, Yun-Huin Lin, Hom-Ti Lee
