Abstract: This invention relates to a manufacturing method of extracting oyster flesh extract using a continuous centrifugal separation device. The continuous centrifugal separation device is provided with: a storage body with a storage space part therein; a rotating body disposed in the storage body and having a rotating shaft part rotating with length direction as axis and having a plurality of rotating blades disposed at an interval at the periphery of the rotating shaft part; a rotating means to rotate the rotating body; an injection part to continuously inject the solution to be separated into the storage space part; a discharge part to continuously discharge the flowing substance which is separated from the side portion of the storage space part where the solution injected from the injection part is centrifugally separated; and a solution discharge part to continuously discharge the remaining solution separated from the flowing substance. The features are that: extracting oyster flesh extract from the oyster flesh and concentrate the oyster flesh extract; stirring and separation process by adding ethanol solution to the concentrated oyster flesh extract solution as a centrifugal separation process for using the continuous centrifugal separation device; in the centrifugal separation process, the concentrated oyster flesh extract solution is sent out from the left side tube toward the outlet tube wherein the quantity delivered can be controlled, the ethanol solution is sent out from the right side tube toward the outlet tube wherein the concentration and the quantity delivered can be controlled, and both solutions can be continuously sent out to the injection part; the two continuously sent-out solutions are stored in the storage body and the rotating body is made to rotate for stirring and centrifugally separating both solutions. Through the above rotation, the flowing substance is gathered to the top corner of the triangular side walls of the sunken storage body. When a predetermined amount of flowing substance is gathered to the top corner, an actuating solution undergoes opening or closing action. In the circumferential direction of the top corner, a plurality of discharge holes are formed at an interval at the opening. Through the plural discharge holes, the flowing substance passes through the discharge part to continuously discharge to the outside. Through the rotation of the above rotating blades which are protruded like a skirt from the periphery of the rotating shaft part, the remaining solution separated from the flowing substance moves toward the top of the storage body and continuously discharges from the solution discharge part, which is disposed at the top of the storage body. The continuously discharged remaining solution, after concentrating, is again added with a predetermined concentration of ethanol solution, followed by separation in a second continuous centrifugal separation device to be continuously discharged from the solution discharge part.
