[0001] This utility model relates to the field of cell culture technology, and in particular to a reactor sieve and a reactor having the same. Background Technology

[0002] A fixed-bed cell reactor is a device used for cell culture. It provides a stable growth environment for cells by using sieves to support sheet-like carriers within the reactor.

[0003] Existing sieves are mostly double-layered or single-layered, forming a space with the external container to hold the carrier. This structure can support the carrier and keep it stable during the reaction. However, this structure makes it difficult to pour out the carrier, and the carrier is easily lost during the washing process after being poured out, and it is also difficult to collect after washing. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a reactor sieve that allows for the simultaneous removal of both the sieve and the reaction carrier, facilitating easy handling and minimizing carrier loss during cleaning. Furthermore, it eliminates the need for re-collecting the reaction carrier after cleaning, saving time.

[0005] This invention also aims to provide a reactor having the aforementioned reactor sieve.

[0006] According to an embodiment of the first aspect of the present invention, a reactor sieve includes a support member, the support member including a bottom surface and a side surface connected to the bottom surface, the bottom surface and the side surface forming a reaction chamber with one end open, the reaction chamber being used to accommodate a reaction carrier, and at least one of the bottom surface and the side surface being provided with a plurality of through holes at intervals.

[0007] A stirring element, which is movably disposed within the reaction chamber for stirring within the reaction chamber;

[0008] It also includes a cylindrical body, the bottom surface of which is provided with an installation port, one end of which is connected to the installation port, and the other end is located in the reaction chamber;

[0009] The stirring component is a propeller blade, which is rotatably connected to the cylinder.

[0010] According to some embodiments of the present invention, the ratio of the total area of ​​the plurality of through holes on the bottom surface to the area of ​​the bottom surface is 0.55-0.65;

[0011] And / or, the ratio of the sum of the areas of the plurality of through holes on the side surface to the area of ​​the side surface is 0.55-0.65.

[0012] According to some embodiments of the present invention, the bottom surface and the side surface are each uniformly provided with a plurality of through holes.

[0013] According to some embodiments of the present invention, the carrier further includes a handle, which is connected to the opening end of the reaction chamber.

[0014] According to some embodiments of the present invention, a support member is also included, which is connected to the side of the bottom surface opposite to the side surface and is used to support the carrier member.

[0015] According to some embodiments of the present invention, the support member includes at least three legs spaced apart, and the lines connecting the at least three legs are not on the same straight line.

[0016] According to some embodiments of the present invention, the support member further includes a flexible foot pad, one of the support leg and the foot pad is provided with an internal thread and the other is provided with an external thread, and the support leg and the foot pad are connected by the internal thread and the external thread.

[0017] According to some embodiments of the present invention, the support member further includes a sealing member, one of the legs and the foot pads is provided with a step along the circumference, and the sealing member abuts against the step and the other.

[0018] This application provides a reactor sieve. By incorporating a support member, the reaction chamber formed by the connection of its bottom and side surfaces can support and accommodate the reaction carrier. Operators only need to place the reaction carrier inside the support member for use. The support member does not need to be fitted with the wall surface, thus eliminating the need for disassembly and assembly, improving operational efficiency. After use, the support member and reaction carrier can be removed together without having to pour the reaction carrier out of the support member, making removal convenient and preventing the reaction carrier from easily remaining in the support member. Furthermore, the reaction carrier and support member can be cleaned simultaneously without having to pour out the reaction carrier. After cleaning, the reaction carrier can be collected, reducing the loss of reaction carrier that may be caused by manual collection, improving the carrier recovery rate, reducing carrier loss, saving costs, and reducing contamination of the reaction carrier by the external environment, thus improving the purity of the carrier and benefiting subsequent cell culture. At the same time, cleaning together saves cleaning time and improves cleaning efficiency.

[0019] The reactor according to a second aspect of the present invention includes a reaction vessel and a reactor sieve as described in the above embodiment, wherein the reactor sieve is disposed inside the reaction vessel.

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0038] A fixed-bed reactor is a reactor filled with granular solid catalysts or solid reactants, forming a bed of a certain height. Gases or liquids flow through the static bed between the particles, simultaneously achieving a heterogeneous reaction process. A key characteristic of this type of reactor is that the solid particles filling the equipment are stationary, unlike moving beds and fluidized beds where the solid materials move within the equipment; it is also known as a packed bed reactor. A fixed-bed cell reactor is a device used for cell culture. It provides a stable growth environment for cells by using sieves to support sheet-like carriers within the reactor.

[0039] Most existing fixed-bed cell reactors use a double-layer sieve structure, with a few using a single-layer structure. However, all suffer from problems such as difficulty in unloading the carrier and difficulty in collecting it after washing. Specifically, in fixed-bed cell reactors, double-sieve designs typically employ an "upper sieve - wall - lower sieve" support method to support the carrier. This structural design effectively fixes the carrier and ensures its stability during the reaction. (Refer to...) Figure 1 The double-layer sieve consists of two sieves. Disassembly requires removing the upper sieve, emptying the carrier, then removing the lower sieve to collect the carrier, followed by cleaning of both sieves and the carrier. Carrier residue remains on both sieves, resulting in poor carrier collection efficiency. In a single-sieve fixed-bed cell reactor, the sieve is typically supported by the "lower sieve - wall - downward pressure of the flow field." This design utilizes fluid dynamics principles, using the downward pressure of the flow field to stabilize the carrier and ensure its stability during the reaction. (Refer to...) Figure 2Compared to double-layer sieves, single-layer sieves have a simpler structure, consisting of only one layer, making cleaning relatively easy. Simply pour out the carrier, remove the lower sieve, collect the carrier, and then clean both the sieve and the carrier. While only one layer needs cleaning compared to double-layer sieves, single-layer sieves still experience carrier residue. During the cleaning and collection of the sieve and carrier, some carrier may be lost. Both structural forms and cleaning methods require skilled personnel to perform the cleaning process effectively, necessitating training to minimize carrier loss. The core issues are the complexity of operation and cleaning due to the sieve structure and the resulting carrier loss during operation.

[0040] Based on this, the present invention proposes a reactor sieve plate. The reactor sieve plate is equipped with a support member that forms a reaction chamber by connecting the bottom and the side surfaces. This facilitates the simultaneous removal of the support member and the reaction carrier, as well as the simultaneous cleaning of the reaction carrier and the support member. The cleaning process is less likely to lose the reaction carrier and saves time in collecting the reaction carrier after cleaning.

[0041] Figures 3-9 This is a schematic diagram of the reactor sieve 100 according to an embodiment of the present invention. (Refer to...) Figures 3-6 The reactor sieve 100 includes a support member 10 for supporting the reaction carrier. The support member 10 includes a bottom surface 11 and side surfaces 12 connected to the bottom surface 11. The bottom surface 11 and side surfaces 12 form a reaction chamber 10a with one open end, into which the reaction carrier can be placed. Specifically, the shape of the bottom surface 11 is not limited; for example, but not limited to, it can be circular, rectangular, hexagonal, irregular, etc. There can be one or more side surfaces 12. For example, when the bottom surface 11 is circular, there is one side surface 12, which is cylindrical. When the bottom surface 11 is rectangular, hexagonal, etc., there can be multiple side surfaces 12, each connected to a different side of the bottom surface 11. In this application, the bottom surface 11 is circular, and the side surfaces 12 are cylindrical.

[0042] Side 12 can be connected to the edge of bottom 11, or side 12 can be connected to any position within the edge of bottom 11. In this application, side 12 is connected to the edge of bottom 11, which increases the volume of reaction chamber 10a.

[0043] At least one of the bottom surface 11 and the side surface 12 is provided with a plurality of through holes 13 at intervals. Specifically, the bottom surface 11 may be provided with a plurality of through holes 13 at intervals, while the side surface 12 may not be provided with through holes 13; or, the bottom surface 11 may not be provided with through holes 13, while the side surface 12 may be provided with a plurality of through holes 13 at intervals; or, the bottom surface 11 may be provided with a plurality of through holes 13 at intervals, and the side surface 12 may be provided with a plurality of through holes 13 at intervals. In the present application, both the bottom surface 11 and the side surface 12 are provided with a plurality of through holes 13 at intervals.

[0044] It is understood that the shape of the through-hole 13 can be, but is not limited to, circular, rectangular, polygonal, elliptical, irregular, etc. The size of the through-hole 13 should be smaller than the size of the reaction carrier to prevent leakage of the reaction carrier from the through-hole 13. The spacing between two adjacent through-holes 13 in a plurality of through-holes 13 can be the same; or, the spacing between two adjacent through-holes 13 in a plurality of through-holes 13 can not be completely the same, for example, some are the same and some are different; or, the spacing between two adjacent through-holes 13 in a plurality of through-holes 13 can be completely different.

[0045] The agitator 20 is movably disposed within the reaction chamber 10a. Specifically, the agitator 20 can be hinged, slidably connected, or rotatably connected to the support member 10; it can also be connected to other components, such as a stirring device fixed to the cover of the reaction vessel 200.

[0046] The agitator 20 is located within the reaction chamber 10a and can agitate the fluid within it. It is understood that the reaction carrier needs to be in contact with a gas or liquid to achieve a heterogeneous reaction. That is, the sieve 100 needs to be placed within a fluid such as a gas or liquid. The agitator 20, located within the reaction chamber 10a, can agitate the fluid, thereby improving the contact efficiency between the fluid and the reaction carrier and promoting mass exchange.

[0047] Therefore, referring to Figures 3-6 According to the reactor sieve 100 of this utility model, by setting a support member 10, the reaction chamber 10a formed by the connection of its bottom surface 11 and side surface 12 can support and accommodate the reaction carrier. The operator only needs to place the reaction carrier in the support member 10 for use. The support member 10 does not need to be fitted with the wall surface, so there is no need to disassemble the support member 10, which improves the operating efficiency. After use, the support member 10 and the reaction carrier can be taken out together without pouring the reaction carrier out of the support member 10. It is convenient to take out, and the reaction carrier is not easy to remain in the support member 10. Moreover, the reaction carrier and the support member 10 can be cleaned at the same time without pouring out the reaction carrier. After cleaning, they can be collected, which reduces the loss of the reaction carrier that may be caused by manual collection of the reaction carrier, improves the carrier recovery rate, reduces carrier loss, saves costs, and reduces the contamination of the reaction carrier by the external environment, improves the purity of the carrier, and is beneficial to subsequent cell culture. At the same time, cleaning together also saves cleaning time and improves cleaning efficiency.

[0048] In some embodiments of this utility model, the ratio of the total area of ​​the plurality of through holes 13 on the bottom surface 11 to the area of ​​the bottom surface 11 is 0.55-0.65; and / or, the ratio of the total area of ​​the plurality of through holes 13 on the side surface 12 to the area of ​​the side surface 12 is 0.55-0.65.

[0049] By setting the ratio of the sum of the areas of the multiple through holes 13 on the bottom surface 11 to the area of ​​the bottom surface 11 to 0.55-0.65; and / or setting the ratio of the sum of the areas of the multiple through holes 13 on the side surface 12 to the area of ​​the side surface 12 to 0.55-0.65, the carrier 10 has a larger open area, which can significantly improve the fluid throughput, help improve the contact efficiency between the culture medium and the carrier, and promote material exchange. At the same time, the resistance encountered by the fluid when passing through the sieve plate 100 is relatively small, which helps to reduce the energy consumption during equipment operation. It also helps to maintain a stable flow field environment and avoid flow field turbulence caused by excessive fluid resistance. Furthermore, the larger open area reduces the cleaning difficulty of the carrier 10 and improves the cleaning efficiency.

[0050] Specifically, the ratio of the total area of ​​the plurality of through holes 13 on the bottom surface 11 to the area of ​​the bottom surface 11 can be 0.55, 0.57, 0.58, 0.60, 0.03, or 0.65. Preferably, the ratio is 0.60. Similarly, the ratio of the total area of ​​the plurality of through holes 13 on the side surface 12 to the area of ​​the side surface 12 can be 0.55, 0.57, 0.58, 0.60, 0.03, or 0.65. Preferably, the ratio is 0.60.

[0051] It is understandable that the ratio of the total area of ​​the multiple through holes 13 on the bottom surface 11 to the area of ​​the bottom surface 11, and the ratio of the total area of ​​the multiple through holes 13 on the side surface 12 to the area of ​​the side surface 12, can be the same or different. If they are different, both can be 0.55-0.65, or one can be 0.55-0.65 while the other is not within the range of 0.55-0.65.

[0052] In some embodiments of this utility model, reference is made to Figure 5 and Figure 7 The bottom surface 11 and the side surface 12 are each provided with a plurality of through holes 13.

[0053] By providing multiple through holes 13 on both the bottom surface 11 and the side surface 12, the fluid can pass through both surfaces, further improving the fluid throughput. By uniformly distributing the through holes 13, the fluid experiences the same resistance at different positions on the bottom surface 11 and the side surface 12, resulting in a uniform and stable flow field that is beneficial for the stable attachment of cells to the reaction carrier.

[0054] It is understood that the through holes 13 on the bottom surface 11 and the side surface 12 can have the same or different shapes. The through holes 13 can be circular, rectangular, polygonal, irregular, etc. In this application, the through holes 13 on the bottom surface 11 are circular and are evenly distributed along the radial and circumferential directions. The through holes 13 on the side surface 12 are rectangular, and the side surface 12 as a whole forms a mesh structure.

[0055] In some embodiments of this utility model, reference is made to Figure 3 and Figure 7 The carrier 10 also includes a handle 14, which is connected to the opening end of the reaction chamber 10a.

[0056] By providing a handle 14 and connecting the handle 14 to the opening end of the reaction chamber 10a, it is convenient to take out the carrier 10.

[0057] Specifically, one or more handles 14 can be provided. When there is one handle 14, both ends of the handle 14 can be connected to the radial ends of the open end of the support member 10. When there are two or more handles 14, the two or more handles 14 can be evenly arranged circumferentially along the open end of the support member 10.

[0058] In some embodiments, the handle 14 can be arc-shaped, such as a semi-circular arc or a U-shaped handle.

[0059] In some embodiments of this utility model, reference is made to Figure 4 The reactor sieve 100 also includes a support member 30, which is connected to the side of the bottom surface 11 away from the side surface 12 and is used to support the carrier member 10.

[0060] By providing a support on the side of the bottom surface 11 away from the side surface 12, the carrier 10 can be supported, which facilitates the flow of fluid through the bottom surface 11 inside and outside the reaction chamber 10a.

[0061] It is understandable that the support 30 can be a base, and there can be one or more bases, etc.

[0062] In some embodiments of this utility model, reference is made to Figure 9 The support member 30 includes at least three legs 31 spaced apart, and the lines connecting the at least three legs 31 are not on the same straight line.

[0063] With at least three spaced-apart support legs 31, and the lines connecting the at least three support legs 31 are not on the same straight line, the support member 10 can be stably supported. At the same time, the contact area between the support legs 31 and the bottom surface 11 is small, which increases the area through which fluid can pass.

[0064] Specifically, there can be three or four or more support legs 31. When there are three support legs 31, the three support legs 31 can be evenly arranged around the axis of the bottom surface 11, which improves the stability of the support. When there are four or more support legs 31, the support legs 31 can be arranged in a rectangle, square, polygon, etc.

[0065] It is understandable that the support leg 31 can be connected to the bottom surface 11 at a certain angle. For example, the angle between the support leg 31 and the bottom surface 11 can be an acute angle, a right angle, an obtuse angle, etc.

[0066] In some embodiments of this utility model, reference is made to Figure 9 The support member 30 also includes a flexible foot pad 32. One of the legs 31 and the foot pad 32 is provided with an internal thread, and the other is provided with an external thread. The legs 31 and the foot pad 32 are connected by the internal thread and the external thread.

[0067] By incorporating flexible foot pads 32, the outriggers 31 are less likely to damage the structural components they contact. The threaded connection between the outriggers 31 and the foot pads 32 improves the reliability of the connection; even under thermal expansion, the foot pads 32 are less likely to detach, thus enhancing the overall stability and safety of the equipment.

[0068] Specifically, the outrigger 31 can be provided with an internal thread, and the foot pad 32 can be provided with an external thread, with the outrigger 31 fitted onto the foot pad 32; or, the outrigger 31 can be provided with an external thread, and the foot pad 32 can be provided with an internal thread, with the foot pad 32 fitted onto the outrigger 31.

[0069] Understandably, the foot pad 32 can be made of materials that meet FDA food-grade certification and are resistant to high-temperature sterilization, such as polytetrafluoroethylene (PTFE).

[0070] In some embodiments of this utility model, reference is made to Figure 9 The support member 30 also includes a seal 33, one of the legs 31 and the foot pad 32 is provided with a step 31a along the circumference, and the seal 33 abuts between the step 31a and the other.

[0071] By setting a seal 33 between the outrigger 31 and the foot pad 32, gases and liquids are less likely to contaminate or corrode the internal and external threads, eliminating the need for cleaning these threads, simplifying the cleaning process, and improving cleaning efficiency. It also reduces the need for frequent disassembly and reassembly of the foot pad 32, improving production efficiency and extending its service life. The seal 33 is pressed between the step 31a of the outrigger 31 and the foot pad 32 via threads, resulting in a simple structure and high sealing reliability.

[0072] Understandably, seal 33 can be a sealing ring, etc. Seal 33 can be made of materials that meet FDA food-grade certification and are resistant to high-temperature sterilization, such as flexible components like silicone.

[0073] In some embodiments of this utility model, reference is made to Figure 7 The reactor sieve 100 also includes a cylinder with an installation port 11a on the bottom surface 11. One end of the cylinder is connected to the installation port 11a, and the other end is located in the reaction chamber 10a. The stirring element 20 is a propeller blade, which is rotatably connected to the cylinder.

[0074] By providing an installation port 11a on the bottom surface 11 and connecting one end of the cylinder to the installation port 11a, the two ends of the cylinder are connected to the inside and outside of the reaction chamber 10a. The stirring element 20 is set as a propeller blade, and the propeller blade is rotatably connected to the cylinder. In this way, the stirring element 20 can stir inside the cylinder, which is less likely to damage the reaction carrier during the stirring process. At the same time, it provides power for the flow of fluid.

[0075] Specifically, the cylinder body is provided with an annular boss along the circumference, one side of which abuts against and connects to the mounting port 11a. At least three legs 31 can be connected to the annular boss, thereby connecting to the bottom surface 11.

[0076] Understandably, the axis of rotation of the rotating blades can coincide with the axis of the cylinder. One or more rotating blades can be installed.

[0077] In some embodiments, the height of the opening at the other end of the cylinder can be on the same plane as the height of the opening end of the support member 10, or it can be less than the height of the opening end of the support member 10.

[0078] The reactor 1000 according to the second aspect of the present invention includes a reaction vessel 200 and a reactor sieve 100 as described in the above embodiment, wherein the reactor sieve 100 is disposed inside the reaction vessel 200.

[0079] The reactor 1000 according to the present invention, by employing the reactor sieve 100 in the above embodiment, shortens the cleaning time, improves the cleaning efficiency, and reduces collection losses.

[0080] It is understandable that the reactor 1000 possesses all the features and advantages of the aforementioned reactor sieve 100, which will not be elaborated upon here.
