Description

Technical Field

[0001] This utility model relates to the field of Poria cocos production technology, and in particular to a sterilization framework for microorganisms. Background Technology

[0002] Poria cocos is a precious medicinal fungus with diuretic, spleen-strengthening, and calming effects, and is widely used in traditional Chinese medicine prescriptions and health product production. The optimal temperature for Poria cocos mycelial growth is 25–28℃, and for fruiting body formation (22–25℃). The optimal substrate humidity during mycelial growth is 60%–65%, and the optimal air humidity during fruiting body formation is 85%–90%. It prefers to grow on pine logs or sawdust. With the advancement of artificial cultivation technology and market demand, large-scale production is required. However, conventional autoclaves cannot meet the needs of large-scale production, and loading bagged culture media requires single-layer stacking or matching hand-held baskets, limiting the number of bags processed per batch. To improve the production and storage of Poria cocos mycelium, large-scale autoclaves are needed. The sterilization chamber is currently the preferred option. Existing technology, publication number CN204951682U, discloses a sterilization device for bagged culture media. This sterilization rack combines a sliding rail and a moving trolley, loading and unloading the rack via matching sliding rails within the chamber. However, this rack becomes unstable and prone to lateral tilting after being loaded with bagged culture media, and is unsuitable for trackless sterilization chambers. Therefore, the sterilization chamber requires a matching frame for loading and transporting bagged culture media for sterilization. Conventional frames are manually handled and loaded, which is time-consuming and labor-intensive. Furthermore, during steam sterilization, the relatively large volume of media sterilized at one time leads to condensation buildup in the early stages, affecting the sterilization effect of the bottom bagged culture media. Therefore, a sterilization frame needs to be developed. Utility Model Content

[0003] This invention provides a sterilization frame for microbial cultures, which solves the problem that the existing frames require manual bending over multiple times to load, resulting in high labor intensity. The use of a mobile trolley for transportation further reduces labor intensity. Furthermore, the accumulation of condensate in the upper frame after multiple layers are stacked can affect the sterilization effect of the lower bagged culture medium.

[0004] This utility model provides the following technical solution:

[0005] A microbial sterilization frame includes a rectangular frame with an open top, the frames being fixedly connected by connecting rods, a door that can be opened or closed at the rear end of the frame, baffles on the four sides and bottom of the frame, the bottom baffle being inclined, a limiting platform inside the frame, and a breathable pad at the bottom of the frame.

[0006] A door that can be closed or opened is installed at the rear of the frame to reduce the labor intensity of bagged culture media during the loading process. The door can be opened, and the bagged culture media can be manually fed into the frame and stacked without having to operate from the top of the frame, thus reducing the number of times the operator bends over and the labor intensity. The setting of the limiting platform allows for the placement of partitions inside the frame to prevent excessive stacking of bagged culture media in a single layer, which could affect the uneven heating of the bagged culture media in the middle of the frame and result in insufficient sterilization time. The ventilated pad prevents condensation from the upper layer of the frame from dripping directly onto the lower frame after the frames are stacked, which could cause water accumulation and affect the sterilization effect of the bagged culture media in the lower frame. During sterilization, the condensation is drained to one side of the ventilated pad. To improve drainage, the bottom baffle is set at an angle of 3 / 5 / 6 / 7 / 9 or 10°. The angle of inclination should not be too large to prevent the center of gravity of the bagged culture media from shifting to the side and compressing the bagged culture media at the bottom, affecting air permeability and sterilization effect.

[0007] Furthermore, the bottom baffle is provided with an arc-shaped groove, and the two ends of the bottom baffle are respectively provided with a first connecting end and a second connecting end. Preferably, the opening of the arc-shaped groove is arranged facing upward to guide the condensate. The first connecting end is located at the lower end of the bottom baffle, and the second connecting end is located at the upper end of the bottom baffle. The bottom baffle is provided with a drainage gap or drainage hole on the side near the first connecting end for drainage.

[0008] Furthermore, the bottom of the frame is provided with supports, and cavities are provided between the supports. The cavities facilitate the transport of the frame, allowing forklifts to insert into the cavities to transport the frame. In addition, combined with the breathable pad, it can prevent the bagged culture medium inside the frame from directly contacting the forklift and prevent the bagged culture medium at the bottom of the frame from being contaminated by other bacteria.

[0009] Furthermore, a limiting plate for limiting the position of the door is provided on the inner side of the frame.

[0010] Furthermore, one end of the door is rotatably mounted on the frame, and the other end is connected to the frame via a bolt, thereby enabling the door to be closed or opened.

[0011] Furthermore, the bolt is a magnetic automatic lock or a pull bolt.

[0012] Furthermore, a toolbox is provided on the frame. Preferably, the toolbox is rectangular and is located on one side of the door, fixed to the baffle by welding. Two toolboxes are arranged vertically, and the toolboxes do not protrude from the frame to avoid obstructing the side-by-side placement of the frames.

[0013] Furthermore, limiting members are provided at the four corners of the top of the frame. The limiting members serve to limit the support of the upper frame when the frames are stacked one on top of the other, preventing the upper frame from sliding or deviating after stacking.

[0014] Furthermore, the frame is provided with reinforcing beams on its sides to improve the structural strength and load-bearing capacity of the frame.

[0015] Furthermore, door frame uprights are provided on both sides of the door body.

[0016] Furthermore, the frame has four insertion holes at the top corners, and an extension frame is also provided at the top of the frame. The extension frame is inserted into the insertion holes through the insertion rod at the bottom.

[0017] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0018] This utility model has the following beneficial effects:

[0019] 1. By setting a door on one side of the frame, the operator can open the door to load bagged culture medium into the frame without having to load it from the top opening of the frame. This reduces the number of times the operator has to bend over to place the bagged culture medium, reduces labor intensity, and improves the convenience of use.

[0020] 2. Limiting devices are provided at the four corners of the top of the frame to limit the support of the upper frame when the frames are stacked, so as to prevent sliding after stacking. At the same time, they protect the four corners of the top of the frame and reduce impact deformation.

[0021] 3. By setting up supports, cavities are formed between the supports, which facilitates forklift operation, reduces manual handling of the frame and labor intensity, and improves ease of use. In addition, the frame is raised by the supports to prevent the bagged culture medium from directly contacting the ground, reducing the risk of contamination by miscellaneous bacteria; and combined with the breathable pad, the risk of contamination of the bottom bagged culture medium is further reduced.

[0022] 4. By tilting the bottom baffle, the condensate is discharged to one side, avoiding the accumulation of condensate which affects the sterilization effect of the bagged culture medium. An arc-shaped groove is set on the bottom baffle to improve the water guiding effect. Attached Figure Description

[0036] Example 1

[0037] Reference Figures 1-3 A sterilization frame for microorganisms includes a rectangular frame with an open top, which is welded together by connecting rods 3. The rear end of the frame has a door 5 that can be opened or closed. The four sides and bottom of the frame are welded with baffles 7. The bottom baffle 11 is inclined at 5° to one side of the frame. The baffles 7 in the same direction are evenly spaced except for the baffle 7 on the side of the door. A limiting platform 8 is provided inside the frame. A breathable pad is laid at the bottom of the frame. The sides of the frame are provided with reinforcing beams to improve the structural strength and load-bearing capacity of the frame.

[0038] Preferably, the spacing between the baffles 7 in the same direction is less than half the diameter of the bagged culture medium, to prevent the bagged culture medium from leaking out of the frame and causing frictional damage to the bag containing the culture medium, thus reducing contamination of the bagged culture medium. The baffles 7 on the same side of the frame as the door 5 are located on the inner side of the frame, while the other three sides are located on the outer side of the frame. The bottom of the frame is also equipped with baffles at equal intervals. This arrangement facilitates the installation of the internal partitions of the frame. The baffles 7 on the door 5 are also located on the outer side. This arrangement improves the closing effect of the door 5 and prevents the bagged culture medium from squeezing the door 5 outward, thus affecting the closing of the door 5. The bottom baffle 11 is inclined to one side of the frame. Specifically, one end of the bottom baffle 11 is welded and fixed to the lower surface of the bottom connecting rod, and the other end of the bottom baffle 11 is set on the upper surface of the bottom connecting rod, thus forming an inclined angle. The inclined bottom baffle 11 drains the condensate generated during the sterilization process to one side. The condensate of the upper frame after stacking is guided along the vertical baffle, so that the condensate is discharged downward. The lower frame drips directly down with the bottom baffle 11 to avoid dripping directly onto the bagged culture medium in the lower layer, which would affect the sterilization effect.

[0039] In this embodiment, the bottom baffle 11 has an arc-shaped groove, and both ends of the bottom baffle 11 have an integrally formed first connecting end 14 and a second connecting end 15. Preferably, the opening of the arc-shaped groove faces upward to guide condensate. The first connecting end 14 is located at the lower end of the bottom baffle, and the second connecting end 15 is located at the upper end of the bottom baffle. The bottom baffle has a drainage gap on the side near the first connecting end 14 for drainage. During installation, the first connecting end 14 is welded and fixed to the lower surface of the bottom connecting rod, and the second connecting end 15 is welded and fixed to the upper surface of the bottom connecting rod on the other side. More preferably, the condensate from the stacked upper frame will drip directly from the first connecting end onto the lower frame, and then be guided down along the vertical baffle on the lower frame, preventing it from dripping directly onto the bagged culture medium inside the lower frame and avoiding the accumulation of condensate. To reduce the obstruction of drainage by the bagged culture medium, an M-shaped protrusion 16 is provided in the arc-shaped groove to improve the drainage effect. Preferably, the M-shaped protrusions 16 are arranged along the length of the bottom baffle to improve the load-bearing capacity of the bottom baffle and prevent deformation due to excessive pressure. More preferably, the M-shaped protrusions 16 are evenly spaced along the length of the bottom baffle 11, and the spacing is smaller than the diameter of the bagged culture medium.

[0040] In this embodiment, door frame posts 6 are provided on both sides of the door body 5; one end of the door body 5 is rotatably mounted on the right post of the frame, and the other end is connected to the left post of the frame via a bolt, thereby opening or closing the door. In this embodiment, the bolt is a pull bolt 1, which is installed inside the door body 5 by a spring. Both the door body 5 and the frame are provided with through holes that match the pull bolt 1. By pulling the pull bolt 1 to move within the through holes, the door body 5 is locked or opened. A limiting plate 9 is provided inside the frame to limit the movement of the door body 5, preventing the door body 5 from moving excessively inside the frame when closed and damaging the bagged culture medium.

[0041] In this embodiment, a door 5 that can be closed or opened is provided at the rear end of the frame to reduce the labor intensity of bagged culture medium during the framing process. The door 5 can be opened to manually feed the bagged culture medium into the frame and stack it, eliminating the need to operate from the top of the frame and reducing the number of times the operator bends over and the labor intensity.

[0042] Preferably, the reinforcing beam is located in the middle of the frame, and the baffle 7 is welded and fixed to the outer side of the reinforcing beam, thereby forming a limiting platform 8 on the inner side of the reinforcing beam. The limiting platform 8 allows for the placement of partitions inside the frame. The partitions are mesh structure partitions to prevent excessive stacking of bagged culture media in a single layer inside the frame, which could affect the uneven heating of the bagged culture media in the middle of the frame and result in insufficient sterilization time.

[0043] In this embodiment, the bottom of the frame is provided with supports 4, and cavities are provided between the supports 4. The cavity provides convenience for the transportation of the frame, allowing forklifts to insert into the cavity to transport the frame. In addition, combined with the breathable pad, it can prevent the bagged culture medium inside the frame from directly contacting the forklift and prevent the bagged culture medium at the bottom of the frame from being contaminated by miscellaneous bacteria.

[0044] In this embodiment, a tool box 2 is provided on the frame. Preferably, the tool box 2 is rectangular for holding simple tools and is located on one side of the door 5, and is fixed to the baffle 7 by welding. Two tool boxes 2 are arranged vertically, and the tool boxes 2 do not protrude from the frame to avoid obstructing the side-by-side placement of the frame.

[0045] In this embodiment, limiting members 10 are provided at the four corners of the top of the frame. The limiting members 10 serve to limit the support 4 of the frame when the frames are stacked one on top of the other, so as to prevent the frame on top from sliding or deviating. The limiting members 10 are L-shaped, covering the outer side of the four top corners of the frame and extending upward, thus protecting the four top corners of the frame.

[0046] Example 2

[0047] The difference between this embodiment and Embodiment 1 is that an extension frame is provided on the frame, and each of the four corners of the top of the frame is provided with a socket 13. The bottom of the extension frame is provided with a matching plug 12. The extension frame is inserted into the socket 13 through the plug 12 and stacked on top of the frame. The extension frame can be flexibly extended according to the needs of use, which improves the convenience of using the frame.

[0048] The structure of the extension frame is a rectangular frame with an open top and no bottom. The frame is welded together by connecting rods 3, and baffles 7 are welded to the four sides of the frame. Insert rods 12 are provided at the four bottom corners of the extension frame, and insertion holes 13 are provided at the four top corners of the extension frame. Multiple extension frames can be stacked according to the needs of use.

[0049] The working principle is as follows: During use, the latch 1 is first pulled open and the door 5 is opened. The bagged culture medium is manually placed from the door 5 into the frame. Before placement, a breathable pad is laid at the bottom of the frame. To improve the air permeability and heating effect of the bagged culture medium in the frame, the bagged culture medium in adjacent layers is placed in the same direction, so that there is a certain gap between the cylindrical bagged culture medium to ensure uniform heating. After placing 3-4 layers of bagged culture medium, a mesh partition is placed, and the layers are placed again. After placement, the door 5 is closed, and the frame is transferred to the sterilization chamber by a forklift. The frames are neatly arranged and stacked. The upper frame is limited by the limiting member 10. The bagged culture medium is sterilized in the sterilization chamber under the set conditions. After sterilization and cooling, the bagged culture medium is inoculated with Poria cocos and cultured under suitable conditions.

[0050] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
