Abstract: An extract manufacturing method of oyster meat extract includes: an extracting process for storing oyster meat in an extracting container that contains solution, and extracting oyster meat extract from the oyster meat in the extracting container; a process of condensing the oyster meat extract obtained from the extracting process; a stirring process for adding ethanol solution into the condensed oyster meat extract and stirring the same; a separating process for separating it into precipitate and supernatant after performing the aforementioned stirring process for a predetermined period of time; and a condensing process for condensing the obtained precipitate, which is characterized in that: the extracting process performs extraction in a state that the pressure is compressed to be higher than normal pressure or the pressure is decompressed to be lower than normal pressure, so as to extract oyster meat from all portions thereof without causing any damage and also extract other kinds of effective components of the oyster meat extract. The stirring process and the separating process are provided as a centrifugal separating process using a continuous centrifugal separating device. The continuous centrifugal separating device includes: a storage body defined therein a storage space part; a rotation body configured in the storage body and including a rotation axle part configured to take the length direction as an axle center direction for performing rotation and a plurality of rotation blades arranged and separated from the periphery of the rotation axle part by a distance; a rotating means for enabling the rotation body to rotate; an injecting part for injecting the solution to be separated into the storage space part; an ejecting part for performing a centrifugal separation to the solution injected from the injecting part so as to continuously eject the flowing object separated from the edge of the storage space part; and a solution ejecting part for continuously ejecting the remaining solution separated from the flowing object. In the aforementioned centrifugal separating process, the solution containing the extracted and condensed oyster meat extract is outputted from a left-side tube to an output tube in an amount adjustable manner, and ethanol solution is outputted from a right-side tube to the output tube in an amount adjustable manner. The aforementioned two solutions are continuously outputted to the injecting part. The continuously outputted two solutions are stored in the storage body. The rotation body is rotated to perform the operation of stirring and centrifugally separating the two solutions in the storage body. With the aforementioned rotation, the flowing object is collected into the vertex angle part side of a sidewall that is depressed toward the storage body as a triangle shape. When the flowing object has been collected into the vertex angle part side of the sidewall depressed as a triangle shape, activating liquid is employed to perform on/off operation. In a circumferential direction of the vertex angle part side of the sidewall depressed as a triangle shape, there are defined a plurality of ejecting holes separately arranged with a predetermined gap. The plurality of ejecting holes are employed to continuously eject the flowing object to outside via the ejecting part. With the rotation from the periphery of the rotation axle part to the plurality of rotation blades arranged and protruded to have a skirt-like edge, the remaining solution separated from the flowing object moves toward the top of the storage body for being continuously outputted from the solution ejecting part configured on the top of the storage body. The continuously ejected remaining solution is condensed and then added with ethanol solution having a predetermined concentration again, which is separated by a second continuous centrifugal separating device and then continuously ejected by the solution ejecting part.
