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.

High-pressure extraction apparatus and method

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.
