It is controlled from the position of 52. That is, when the slider 52 is in the position of the first foot sensor 53-1 shown in FIG. 1, the plunger 41 is in the forward end position of the cylinder 40, and the slider 52 is in the position of the second foot sensor 53 shown in FIG. When in the position of -2, since the plunger 41 is in the retracted end position of the cylinder 40, the servomotor 30 is operated based on the output of the first foot sensor 53-1 and the output of the second foot sensor 53-2. By controlling the rotation, the plunger 41 in the cylinder 40 can be reciprocated between the forward end position and the backward end position.

A fluid inlet 61 to be processed and a fluid outlet 62 to be processed are provided at the tip of the cylinder 40. Then, the fluid inlet 61 to be treated is guided into the container A via the check valve 60, the pipe joint 63, and the tube 64, and the fluid outlet 62 to be treated is the ultra-high pressure wet micronization part 70 and the pipe joint. It is guided to the container A via 65.

Then, when the container A is filled with the fluid to be processed and is in the position shown in FIG. 3, when the plunger 41 is retracted in the cylinder 40 by the rotation of the servomotor 30, the fluid to be processed in the container A becomes a tube. It is guided into the cylinder 40 from the fluid inlet 61 to be processed via the pipe joint 63 and the check valve 60, the slider 52 reaches the position of the second foot sensor 53-2, and the plunger 41 is moved into the cylinder 40. The fluid to be processed in the cylinder 40 is extruded from the fluid outlet 62 to be processed into the ultra-high pressure wet fine particle section 70, whereby the fluid to be processed is pushed out from the nozzles 71a and 71b of the ultra-high pressure wet fine particle section 70. Is ejected at an ultra-high pressure, whereby the particles contained in the fluid to be treated are atomized. The finely divided fluid to be treated is returned to the container A via the pipe joint 65, and the above treatment is performed once or a plurality of times to obtain desired fine particles of the fluid to be treated in the container A.

In the ultra-high pressure wet micronization apparatus 100 of this embodiment, the circulation path is cleaned prior to the ultra-high pressure wet micronization of the fluid to be treated, whereby the inside of the circulation path is filled with pure water. That is, pure water is contained in the container B, the container B is moved to the circulation position where the container A is arranged in FIG. 3, the tube 64 is inserted into the container B, and the servomotor 30 is driven to drive the cylinder 40. The plunger 41 inside is reciprocated. Here, when the plunger 41 is retracted in the cylinder 40, the pure water in the container B is guided into the cylinder 40 from the fluid inflow port 61 to be processed via the tube 64, the pipe joint 63, and the check valve 60. When the plunger 41 is advanced, the pure water in the cylinder 40 is returned from the fluid outlet 62 to be processed into the container B via the ultra-high pressure wet fine particle 70 and the pipe joint 65, and this process is repeated. The cleaning process of the circulation path is performed. When this cleaning process is completed, the circulation path is filled with pure water.

In this state, the fluid to be processed is contained in the container A, and the empty container B is moved to the circulation position (step 501).

Next, the tube 64 is inserted into the container A, and the servomotor 30 is driven to execute the circulation process (step 502). This circulation process is performed from 3 to 5 round trips of the plunger 41 in the cylinder 40, that is, 3 to 5 shots. By this process, the pure water in the circulation path is replaced with the fluid to be treated, and the circulation path is filled with the fluid to be treated. At this time, the pure water in the circulation path is collected in the empty container B.

After that, the container A containing the fluid to be processed is moved to the circulation position (step 503), the ultrasonic oscillator 10 is started, and the ultrasonic dispersion processing of the fluid to be processed in the container A is performed (step 504). Then, the servomotor 30 is driven to start the circulation process, and the ultra-high pressure wet micronization process of the fluid to be processed is performed (step 505).

The ultra-high pressure wet micronization treatment by the circulation treatment of the fluid to be treated is performed, for example, about 10 passes. Here, one pass corresponds to, for example, 3 to 5 shots in which the ultra-high pressure wet micronization treatment of the fluid to be processed in the container A goes through.

Next, it is checked whether or not the cyclic processing is performed on the set path set corresponding to the sample process, that is, whether the set path has elapsed (step 506). Here, if the set path has not elapsed (NO in step 506), the process returns to step 506 and the circulation process is repeated until the set path has elapsed, but when it is determined that the set path has passed (in step 506). YES), the empty container B is moved to the circulation position, the fluid to be treated after the ultra-high pressure wet micronization treatment by the circulation treatment is guided into the empty container B, and the sampling process is performed (step 507).

In step 508, based on this sampling process, it is determined whether or not to end the ultra-high pressure wet micronization process by the circulation process of the fluid to be processed. Here, it is necessary to continue the ultra-high pressure wet micronization treatment, and if it is determined that the ultra-high pressure wet micronization treatment has not been completed (NO in step 508), the process returns to step 508 and the fluid to be treated is circulated. Continue the ultra-high pressure wet micronization process. Further, when it is determined in step 508 that the ultrahigh pressure wet micronization treatment is completed (YES in step 508), the empty container B is moved to the circulation position, and the processing end fluid is collected in the empty container B. The end fluid recovery process is performed (step 509).

This processing end fluid recovery process is continued until the container A is empty and the container B is full, and when the container A is empty and the container B is full, it is determined to be the process end fluid recovery process (step). YES at 501). The process of the ultra-high pressure wet micronization apparatus 100 is completed.
