  In these conventional treatments, an expensive filter medium is used, or an inexpensive filter medium is used, and time and effort are required. In addition, the enzyme treatment has a problem that an enzyme material is expensive and a treatment time is required.

  By the way, in order to effectively use (function) the centrifugal separator and the filtration processing means, it is desired to aggregate the suppressed components that become the precipitate and the filtrate in a short time. For this reason, there is a demand for an agglomeration technique that makes the component to be suppressed in the extract to be treated a large flock.

  At present, the extraction liquid is cooled in an acidic region to promote aggregation, but it is incomplete.

  The problem to be solved by the present invention is to perform an intermediate process for flocking (aggregating) prior to the clarification process by centrifugation or filtration in order to remove the suppressed components in the extract.

  That is, after cooling the extract in an acidic region (at a temperature not exceeding 10 ° C. and freezing), applying a vibration including sonication for a predetermined time (shaking treatment) promotes flocking (aggregation). Here, it is also considered to adjust the amount of precipitation by changing (controlling) the processing time and frequency.

In addition, although there is a proposal to irradiate ultrasonic waves when extracting components such as powdered coffee (see, for example, Patent Documents 8 and 9), a stirring effect and a bactericidal effect for rapid and high concentration extraction were obtained. However, there is no proposal regarding the shaking treatment (and the vibration piping as the shaking treatment means) having the above-mentioned technical solution problem as a target effect.
