It can be used as a work area when a workpiece is input. That is, unlike the conventional case, three sides around the container can be used as a work area.
Furthermore, since the bearing portion is provided only on one side (one side) of the container, maintenance places when the container is rotationally driven can be combined into one place.
Moreover, according to the container rotation type processing apparatus according to the above-described configuration, it is possible to eliminate the other-side bearing portion, a large pedestal, and the like (that is, the container rotation type processing apparatus can be configured compactly). In the case where the container rotation type processing apparatus is disposed in the clean room, it is possible to realize space saving of the clean room. Furthermore, contamination during the maintenance process of the bearing portion, the motor, and the reduction gear can be prevented.

[0029]
The container rotation type processing apparatus according to the present embodiment is configured as described above and functions as follows. Below, the case where the mixing drying process of a to-be-processed object is performed using the container rotation type processing apparatus concerning this embodiment is demonstrated.
[0030]
First, in the container rotation type processing apparatus according to the present embodiment, an object to be processed such as a granular material to be uniformly processed (mixed, dried, etc.) is input into the container main body 11 from the input port 16. . Here, examples of the object to be treated such as a granular material include a drug substance or an intermediate in the chemical / pharmaceutical industry.
[0031]
Next, after the object to be processed is put into the container main body 11, the inside of the container main body 11 is depressurized by using the pressure adjusting means 3, the pressure adjusting pipe 31 and the like, and the heat exchanging means 2, the jacket 12 and the like are The container 1 is rotated using the drive means (electric motor 5, reduction gear 6, etc.) and the drive shaft 4 while heating the inside of the container main body 11.

According to such a configuration, it is possible to more effectively carry out mixing / drying processing of heat-sensitive drugs, foods, and the like.
[0032]
In the present embodiment, by appropriately controlling the decompression step, the heating step, and the rotation step, the object to be processed is mixed and dried, and after the processing is completed, the inside of the container main body 11 A step of returning the pressure to the atmospheric pressure state (return pressure step) is performed.
And after the rotation process and the decompression process of the container 1 are complete | finished, the processed material which the appropriate mixing and drying process was complete | finished is discharged | emitted from the discharge port 17, and is conveyed to the following process.
[0033]
As described above, the container rotating type processing apparatus according to the present embodiment can be configured and function to obtain the following effects.
[0034]
First, according to this embodiment, since only one side 1a of the container 1 is supported by the one end 4a of the drive shaft 4 (because of a so-called “cantilever structure”), A bearing part and a pedestal (a pedestal formed in a size exceeding the full length of the container) are not required. Therefore, according to this embodiment, it is possible to obtain a container rotation type processing apparatus that can be configured more compactly than in the past.
[0035]
Conventionally, since components such as bearings are provided on both sides of the container 1 in the direction of the rotation axis, a space for performing maintenance work on both the left and right sides of the container 1 is required. However, in the present embodiment, as described above, since all the components (heat exchange means 2 and pressure adjustment means 3 etc.) other than the container 1 are provided on the other end 4b side of the drive shaft 4, The space for performing the maintenance work may be provided only on the other end 4 b side of the drive shaft 4. Therefore, according to this embodiment, it is possible to reduce the installation space of the apparatus including the space for performing maintenance work. Furthermore, since the maintenance work can be performed at one place (for example, the trouble of moving or the like is saved), the maintenance work can be facilitated.
[0036]
In addition, since components such as bearings are conventionally provided on the left and right sides of the container, the work piece is put into the container around the rear of the bearing or the like, or through the bearing. From the front (or back) side. If it is carried out over a bearing or the like, the distance from the container or the like is increased, and the object to be treated may adhere to the bearing or the like, which is not preferable. Further, the front or back side of the container is not preferable because it is in the rotation direction of the container and may fall within the rotation range.
However, in the present embodiment, since components such as bearings are not provided on the other side 1b of the container 1, the object to be processed can be introduced into the container 1 from the other side 1b. That is, according to the present embodiment, the object to be processed can be charged without facing the rotation direction of the container 1 and without any obstacles.
In addition, in the apparatus according to the prior art as a work area other than the input of the workpiece, basically the front side and the back side of the container not provided with a bearing or the like were used. According to the form, in addition to these, the other side 1b of the container 1 can also be used as a work area.
[0037]
Further, according to the container rotation type processing apparatus according to the above-described configuration, there is no need to provide a bearing portion, a large pedestal, or the like on the other side 1b of the container 1, so when arranging the container rotation type processing apparatus in the clean room, For example, as shown in FIG. 1, it can be set as the clean room which can accommodate only the container 1 provided in the left side area | region of the partition plate 9. FIG. In other words, in addition to the compactness of the device itself, it is possible to realize space saving in the clean room. Moreover, since the cause of contamination of the clean room (bearing portion on the other side and large pedestal) is reduced, the clean room can be kept as clean as possible.
[0038]
Further, although not particularly shown in FIG. 1, when a mechanism for raising and lowering the container 1 is added, according to the present embodiment, a simpler configuration than the container rotating type processing apparatus according to the prior art can be obtained. . That is, in the prior art, it is necessary to provide a cylinder or the like for raising and lowering both shafts of the container 1 on both sides of the container (below the bearings) and to configure the lifting means so that these are driven in synchronization. However, according to this embodiment, since the container 1 is supported by the drive shaft 4 and this drive shaft 4 is supported by the speed reducer 6 constituting the drive means (because of the cantilever structure), this speed reducer. It is only necessary to provide an elevating means comprising a cylinder or the like only under 6, and no two elevating means nor a means for synchronizing them is required as in the prior art. Therefore, according to the present embodiment, the container 1 can be configured to move up and down based on a simpler structure.
[0039]
For example, as a structure which raises / lowers the container 1, what is shown in FIG. 2 is mention | raise | lifted. FIG. 2 is a cross-sectional view of the main part when a container rotating type processing apparatus provided with lifting means (not shown) is installed in a clean room.
According to FIG. 2, elevating means is provided only below the speed reducer 6, and the container is supported by the drive shaft 4 provided on the speed reducer 6. It is arranged in a partitioned clean room. The partition plate 9 is formed with a long hole 91 through which the drive shaft 4 can be moved up and down, and the drive shaft 4 is provided with a plate member 92 so as to cover the long hole 91. According to the configuration shown in FIG. 2, since the plate member 92 moves through the long hole 91 of the partition plate 9 and can be sealed when moved, the container can be raised and lowered via the drive shaft 4. In addition, the shielding state inside and outside the clean room can be effectively maintained. Therefore, it is possible to keep the clean room as clean as possible.
[0040]
The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention.
[0041]
