Description

  The present invention relates to a raw material supply apparatus for liquid products such as pharmaceuticals and beverages.

  Isolators are used in the manufacture of liquid products such as liquid pharmaceuticals (see, for example, Patent Document 1). By adjusting the raw material in the isolator and filling the raw material tank, it is possible to prevent contamination of liquid products during the manufacturing process.

  The raw material tank filled with the raw material in this manner is removed from the isolator and connected to various manufacturing apparatuses that perform predetermined processing. That is, the raw material tank is detachable from the manufacturing apparatus. For example, the raw material tank can be attached to and detached from a pipe that connects the raw material tank and a preparation tank that is one of the manufacturing apparatuses. For this reason, when the raw material tank is removed, the inside of the pipe is exposed to air. In order to keep the inside of a pipe clean even if it is exposed to air, various manufacturing apparatuses such as the pipe and a preparation tank are installed in a clean room.

  However, it is necessary to configure a large clean room that only accommodates such various manufacturing apparatuses, which causes an increase in cost. Thus, it is difficult to maintain cleanliness and operate at low cost while using a raw material tank that can be attached to and detached from various manufacturing apparatuses.

  In addition, when the above-described piping, adjustment tank, or the like is not installed in the clean room, for example, a configuration in which the exposure of air is avoided by not connecting the raw material tank and connecting it to the preparation tank by piping is possible. . However, particularly in existing plants, the arrangement of the raw material tank and the adjustment tank may be restricted, and it may be difficult to adopt such a configuration.

  Such a problem exists not only for pharmaceutical products but also for liquid products including beverages.

  The cleaning means is for cleaning a portion of the raw material tank 10, the first pipe 20 and the second pipe 30 exposed to the outside air in a state where the raw material tank 10 is detached from the first pipe 20 and the second pipe 30. Various devices capable of supplying fluid. In the present embodiment, the parts exposed to the outside air are the first on-off valve 13a and the first on-off valve among the first pipe 20, the second pipe 30, the first receiving pipe 11 and the second receiving pipe 12 of the raw material tank 10. It is on the upstream side of 13b and on the downstream side of the second on-off valve 18 in the discharge pipe 16 of the raw material tank 10.

Moreover, these on-off valves are controlled to open and close by a control device. In addition, the supply source of the cleaning fluid or the water for injection (not shown) is controlled by the control device so that the supply of the cleaning fluid or the water for injection is stopped.

  The operation of the liquid product raw material supply apparatus 1 having the above-described configuration will be described with reference to FIGS. 2 to 5 are schematic diagrams for explaining the operation of the liquid product raw material supply apparatus. In these drawings, the closed state of each valve is indicated by black, and the open state is indicated by white.

  FIG. 2 shows a state in which the raw material tank 10 is removed from the first pipe 20 and the second pipe 30. Specifically, the first receiving pipe 11 and the second receiving pipe 12 of the raw material tank 10 are removed from the first pipe 20 (downstream pipe portion 23). Similarly, the discharge pipe 16 of the raw material tank 10 is removed from the second pipe 30 (upstream pipe portion 31).

  The material tank 10 thus removed is used to transport the injection solution material from the weighing chamber to the adjustment chamber. In the present embodiment, the raw material tank 10 is carried into a weighing chamber and filled with an injection solution raw material weighed to a predetermined amount in the weighing chamber. For example, in the raw material tank 10, after the injection solution raw material is supplied from the isolator, the first on-off valve 13a, the first on-off valve 13b, and the second on-off valve 18 are closed. In this way, the raw material tank 10 passes through an air shower or a pass box (UV, EOG, etc.) with the injection solution raw material sealed inside, and is brought into the adjustment chamber. In addition, the removal and conveyance of the raw material tank 10 may be performed manually, and may be performed using various conveyance apparatuses.

  While the raw material tank 10 is removed and carried, a portion surrounded by a dotted circle is exposed to the air in the adjustment chamber and the air in the weighing chamber. The portion surrounded by the dotted circle is a portion upstream of the first on-off valve 13a and the first on-off valve 13b in the first receiving pipe 11 and the first receiving pipe 11, and a second on-off valve in the discharge pipe 16. 18 is a downstream portion. Moreover, the inside of the first pipe 20 and the second pipe 30 is also exposed to the air in the adjustment chamber.

  Thus, the part exposed to the air of the raw material tank 10, the 1st piping 20, and the 2nd piping 30 will no longer be clean at this stage. Hereinafter, a portion surrounded by these dotted circles and a portion exposed to the air inside the first pipe 20 and the second pipe 30 are referred to as a portion to be cleaned.

  FIG. 3 shows a state in which the raw material tank 10 is attached to the first pipe 20 and the second pipe 30 and is cleaned with the cleaning fluid.

  First, the raw material tank 10 filled with the injection solution raw material is attached to the first pipe 20 and the second pipe 30. Specifically, the first receiving pipe 11 and the second receiving pipe 12 of the raw material tank 10 are connected to the first pipe 20 (downstream pipe portion 23) by the first joint 15. Similarly, the discharge pipe 16 of the raw material tank 10 is connected to the second pipe 30 (upstream pipe portion 31) by the second joint 17.

  Then, the discharge opening / closing valve 26 and the first supply opening / closing valve 27 are opened for the first pipe 20 by the control of the control device. For the second pipe 30, the second supply opening / closing valve 37 is closed. Further, the cleaning on-off valve 42 and the discharge on-off valve 43 are opened.

  By such valve opening / closing control, a flow path from the supply source of the cleaning fluid to the discharge pipe 25 is formed for the first pipe 20. Further, a flow path is formed from the supply source of the cleaning fluid to the downstream piping section 33 for the cleaning pipe 40, the midstream piping section 32, the upstream piping section 31, and the discharge piping 41.

  Then, the control device performs control to supply the cleaning fluid from the supply source to the first pipe 20 and the cleaning pipe 40. Thus, the cleaning fluid flows through the first pipe 20 and cleans the portion to be cleaned, and then is discharged from the discharge pipe 25 and sent to the processing apparatus for the cleaning fluid. The cleaning fluid flows from the cleaning pipe 40 through the second pipe 30 to clean the portion to be cleaned, and is then discharged from the discharge pipe 41 and sent to the cleaning fluid processing apparatus. Such cleaning with the cleaning fluid ensures that the portion to be cleaned is clean.

  Note that the cleaning of the portion to be cleaned may be performed by CIP only, SIP only, or SIP after CIP.

  Further, as shown in FIG. 3, when the downstream pipe portion 23 is arranged in the vertical direction, the cleaning fluid may stay below the portion of the downstream pipe portion 23 to which the discharge pipe 25 is connected. Seem. However, by shortening the distance from the said part to the 1st on-off valve 13, even if the cleaning fluid stays, it can be suppressed to a small amount. Since the cleaning fluid can be blown off to the discharge pipe 25 by the gas pressure of SIP or evaporated by the heat of SIP, the cleaning fluid does not stay in the downstream pipe portion 23.

  With reference to FIGS. 4 and 5, the operation of feeding the injection solution raw material from the raw material tank 10 to the preparation tank 201 and co-washing the raw material tank will be described.

  As shown in FIG. 4, after the cleaning of the portion to be cleaned is completed, the injection solution raw material in the raw material tank 10 is sent to the preparation tank 201. Specifically, the control device opens the second on-off valve 18. Further, the control device opens the second supply opening / closing valve 37 for the second pipe 30. Further, the control device closes the cleaning on-off valve 42 and the discharge on-off valve 43. Thereby, the injection solution raw material is fed from the raw material tank 10 to the preparation tank 201. The injection solution raw material may be fed by the weight of the injection solution raw material itself or may be sent by pressure with an inert gas such as nitrogen.

  Next, the control device closes the first supply on-off valve 27a for the first pipe 20a, opens the first supply on-off valve 27b, and closes the discharge on-off valve 26b for the first pipe 20b. . Further, the control device opens the first on-off valve 13 b of the raw material tank 10. By such valve opening / closing control, a flow path from the first pipe 20b to the raw material tank 10 is formed.

  And a control apparatus performs control which supplies the water for injection to the 1st piping 20b from the supply source. Thereby, the water for injection flows through the first pipe 20 b and is supplied to the bottom of the raw material tank 10. As described above, since the injection solution raw material is fed from the raw material tank 10 to the preparation tank 201, the raw material tank 10 is almost empty, but a small amount of the injection solution raw material may remain. Such remaining injection solution raw material is sent to the preparation tank 201 together with water for injection. That is, the injection solution raw material remaining in the raw material tank 10 is washed with water for injection which is one of the raw materials constituting the injection solution.

  As shown in FIG. 5, further washing is performed using the first pipe 20a. Specifically, for the first pipe 20a, the control device opens the first supply opening / closing valve 27a and closes the discharge opening / closing valve 26a. For the first pipe 20b, the first supply opening / closing valve 27b is closed. Further, the control device opens the first on-off valve 13 a of the raw material tank 10. By such valve opening / closing control, a flow path from the first pipe 20a to the raw material tank 10 is formed.

  And a control apparatus performs control which supplies the water for injection to the 1st piping 20a from the supply source. Thereby, the water for injection distribute | circulates the 1st piping 20a, is sprayed from the shower head 14, and is supplied to the inner surface from the upper part of the raw material tank 10. FIG. As a result, a small amount of the injection solution raw material adhering to the inner surface of the raw material tank 10 is sent to the preparation tank 201 together with the water for injection.

  Next, removal of the raw material tank 10 will be described. Although not particularly shown, the control device feeds the injection solution raw material from the raw material tank 10 to the preparation tank 201, and then performs cleaning with the cleaning fluid in the same state as in FIG. And after completion | finish of washing | cleaning, the raw material tank 10 is removed as shown in FIG. Thereafter, returning to FIG. 2, the injection solution raw material is supplied from the isolator to the raw material tank 10, and the steps shown in FIGS. 3 to 5 are repeated until a predetermined amount of injection solution is obtained.

  In the raw material supply apparatus 1 described above, the raw material tank 10 filled with the injection liquid raw material weighed in the weighing chamber is transported and detachable from the first pipe 20 and the second pipe 30. Therefore, to-be-cleaned parts (upstream from the first on-off valve 13a and the first on-off valve 13b in the first receiving pipe 11 and the second receiving pipe 12, downstream from the second on-off valve 18 in the discharge pipe 16, and The insides of the first pipe 20 and the second pipe 30 are exposed to air and cannot maintain cleanliness. However, before the injection solution raw material is sent from the raw material tank 10 to the preparation tank 201, the portion to be cleaned is cleaned with a cleaning fluid (see FIG. 3). For this reason, after cleaning the inner surfaces of the first pipe 20 and the second pipe 30 through which the injection solution raw material and the water for injection flow, they can be supplied to the preparation tank 201.

  Moreover, as for the raw material supply apparatus 1 of this embodiment, the 1st piping 20 and the 2nd piping 30 are wash | cleaned. Therefore, after the raw material tank 10 is removed, it is possible to arrange those pipes in an environment where the raw material tank 10 is temporarily exposed to air. For this reason, it is not necessary to accommodate the 1st piping 20, the 2nd piping 30, the manufacturing means 200, etc. in a clean room. For this reason, the increase in the cost accompanying a large clean room can be avoided.

  Thus, according to the raw material supply apparatus 1, while using the raw material tank 10 detachable from the injection solution manufacturing means 200, the injection solution raw material is supplied to the manufacturing means 200 at a low cost while maintaining cleanliness. be able to.

  In addition, the plant of the structure which connects an isolator, a raw material tank, and various manufacturing apparatuses fixedly with piping is considered. Especially in the case of pharmaceuticals, because there is a situation that you do not want to pump the raw material using a pump etc., a raw material tank and various production equipment are installed in the room below the room where the isolator is installed, and the isolator is connected to the upper and lower floors. A plant configured to connect a raw material tank with a pipe is operated.

  In a plant having such a configuration, a configuration in which isolators and raw material tanks are arranged on the upper and lower floors is essential, so that there is a great restriction that two floors are required for the design and construction of the plant. In particular, it is difficult to construct a plant having such a configuration in an existing building.

  On the other hand, in the raw material supply apparatus 1 of this embodiment, since the raw material tank 10 can be removed from the manufacturing means 200, restrictions on the design and construction of the plant 100 including the isolator and the raw material tank 10 and the manufacturing means 200 are relaxed, Application in existing buildings becomes easy. For example, in a plant that manufactures a small variety of products, the raw material tank 10 is made relatively small, and the raw material tank 10 is installed in an isolator and a weighing chamber so that injection raw materials can be supplied. Then, the raw material tank 10 is transported and can be attached to the manufacturing means 200 installed in the adjustment room on the same floor, for example. That is, there is no need to configure the plant 100 across two floors, and there is an effect that the plant 100 including the raw material supply device 1 can be easily applied to an existing building.

  Moreover, the raw material supply apparatus 1 performs cleaning (see FIG. 3), liquid feeding of the injection liquid raw material, and co-washing (see FIGS. 4 and 5) by the control device. As a result, a series of steps for producing the injection solution can be automatically and reliably executed unattended, and the running cost can be reduced.

  In particular, as shown in FIG. 3, since the portion to be cleaned is cleaned with the cleaning fluid by the control device, the cleaning process can be executed automatically and reliably.

  Moreover, you may make it a control apparatus determine with the raw material tank 10 being removable from the 1st piping 20 and the 2nd piping 30 after completion of a washing | cleaning process. Further, the control device may display the determination result in a form that can be recognized by the worker of the plant 100. For example, it may be displayed on the screen that the raw material tank 10 can be removed, or may be displayed on various devices such as a lamp. Thereby, an operator can be surely notified that the raw material tank 10 can be removed.

  Moreover, the raw material supply device 1 can wash the injection solution raw material remaining in the raw material tank 10 with water for injection by the control device. Thereby, it is possible to prevent the injection solution raw material from remaining in the raw material tank 10 and wasting it. In particular, since the injection solution raw material is expensive even in a small amount, the effect of reducing the waste of the injection solution raw material is remarkable.

  Moreover, the raw material supply apparatus 1 can supply the injection liquid raw material to the raw material tank 10 by an isolator. Thereby, when filling the raw material tank 10 with an injection liquid raw material, a possibility that various germs etc. may mix can be reduced.

<Embodiment 2>
In the present embodiment, a modification of the first pipe 20 is shown. FIG. 6 is a schematic view of a raw material supply apparatus according to the second embodiment. In addition, the same code | symbol is attached | subjected to the same thing as Embodiment 1, and the overlapping description is abbreviate | omitted.

  As shown in FIG. 6A, in the first pipe 20a of the present embodiment, the downstream pipe part 23 has a vertical part 23a arranged substantially vertically and a substantially horizontal horizontal part 23b bent from the vertical part 23a. It consists of and. The discharge pipe 25 is connected to the intersection of the vertical portion 23a and the horizontal portion 23b and extends substantially horizontally.

  As in the first embodiment, the first on-off valve 13a is closed, the discharge on-off valve 26 is opened, and the cleaning fluid is supplied to the first pipe 20a. Thereby, the inside of the 1st piping 20a and the upstream of the 1st on-off valve 13a among the 1st receiving piping 11 can be wash | cleaned.

  And as shown in FIG.6 (b), the washing | cleaning fluid is gradually discharged | emitted from the inside of the 1st piping 20a at the time of completion | finish of washing | cleaning. At this time, since the downstream side of the first pipe 20a is the horizontal portion 23b, the cleaning fluid flows through the discharge pipe 25 and is thus discharged, so that it is difficult to stay in the first pipe 20a. Yes. Even if the cleaning fluid remains in the first pipe 20a, the cleaning fluid is surely discharged from the first pipe 20a by SIP.

  As described above, according to the present embodiment, the cleaning fluid can be more reliably discharged from the first pipe 20a, so that the cleaning fluid flows into the raw material tank 10 in the subsequent steps. Can be prevented.

  In addition, you may apply the structure of the 1st piping 20a provided with such a vertical part 23a and the horizontal part 23b to the upstream piping part 31 of the 1st piping 20b or the 2nd piping 30. FIG.
