Description

Technical Field

[0001] This utility model relates to the field of microbial fermentation technology, and in particular to an adjustable microbial fermentation device. Background Technology

[0002] In microbial fermentation, the structure and performance of the fermentation apparatus significantly impact the fermentation effect. Furthermore, the specifications and height of the fermentation containers used in microbial fermentation often vary depending on experimental or production needs. Existing fermentation apparatuses typically have fixed fermentation chambers, making them inflexible in adapting to fermentation containers of different heights. For example, Chinese utility model patent CN218404223U discloses a microbial fermentation apparatus with adjustable shading. It uses a side-opening slot to place microbial culture vessels, and above them, a motor-driven conveyor belt rotates multiple rotating blades to control sunlight exposure. Clearly, the internal space of this fermentation apparatus is fixed, limiting it to fermentation containers of a specific height and size. This not only restricts the equipment's versatility but may also lead to fermentation containers not being fully placed in the chamber or becoming unstable within the chamber, thus affecting the fermentation effect.

[0003] Therefore, there is an urgent need for a fermentation device that allows for adjustment of the size of the fermentation chamber. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable microbial fermentation device that uses a special folded silicone structure design to adjust the size of the fermentation chamber to accommodate fermentation containers of different heights, thus effectively solving the problem mentioned in the background art that existing fermentation devices cannot adapt to fermentation containers of different heights.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable microbial fermentation device includes a fermentation chamber with an upward-facing placement cavity at the top. The placement cavity is provided with a bracket for placing microbial fermentation culture vessels. A telescopic support cylinder distributed around the placement cavity is fixed to the top of the fermentation chamber. The telescopic support cylinder has a ring-shaped folded silicone wall structure. An installation frame matching the shape of the opening of the placement cavity is fixed to the top of the telescopic support cylinder. The installation frame is connected to a detachable cover plate via a magnetic suction device.

[0007] Furthermore, the magnetic attraction device includes a first magnet block fixed on the mounting frame and a second magnet block fixed on the cover plate, wherein the first magnet block and the second magnet block are magnetically attracted to each other.

[0008] Furthermore, the upper part of the mounting frame is provided with a positioning step, the outline of which is adapted to the outer periphery of the cover plate.

[0009] Furthermore, a sealing gasket is provided between the mounting frame and the cover plate.

[0010] Furthermore, the sealing gasket is fixed to the lower surface of the cover plate by adhesive bonding.

[0011] Furthermore, the cover plate has a through observation port in the middle, and a light-transmitting plate is installed in the observation port.

[0012] Furthermore, a light-shielding plate for covering the observation port is slidably installed on the upper surface of the cover plate, and the upper surface of the light-shielding plate is provided with a push-pull handle.

[0013] Furthermore, there are two light-shielding plates, which are symmetrically distributed above the observation port. The upper surface of the cover plate is provided with two inverted L-shaped guide strips located on both sides of the light-shielding plates. A guide groove is formed between the guide strips and the cover plate to allow the light-shielding plates to slide.

[0014] Furthermore, the cover plate is an opaque plastic plate, and the light-transmitting plate is a transparent polycarbonate plate.

[0015] Furthermore, the side wall of the fermentation box is provided with at least one recess distributed along the height direction, and the outer periphery of the mounting frame is connected with a support plate corresponding to the recess.

[0026] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0027] Please refer to Figures 1-6 This embodiment provides an adjustable microbial fermentation device, including a fermentation tank 1 with an overall cuboid shape. The upper part of the fermentation tank 1 has an upward-facing placement cavity 11. The placement cavity 11 is equipped with a bracket 2 for placing microbial fermentation culture vessels. A telescopic support cylinder 3 is fixed to the top of the fermentation tank 1 and distributed around the placement cavity 11. The telescopic support cylinder 3 has a ring-shaped folded silicone wall structure. The top of the telescopic support cylinder 3 is fixed with a mounting frame 4 that matches the shape of the opening of the placement cavity 11. The mounting frame 4 is connected to a detachable cover plate 5 by a magnetic attraction device. By designing a special folded silicone structure, the height can be adjusted by simply pushing and pulling up and down, realizing the adjustment of the size of the fermentation cavity, which can well adapt to fermentation containers of different heights. In addition, the cover plate is installed by magnetic attraction, which also facilitates quick assembly and disassembly, improving the convenience of operation.

[0028] In some specific implementation methods, refer to Figure 3 and Figure 4 The magnetic attraction device includes a first magnet block 41 fixed to the mounting frame 4 and a second magnet block 51 fixed to the cover plate 5. The first magnet block 41 and the second magnet block 51 are magnetically attracted to each other. Through the magnetic attraction between the first and second magnet blocks, the cover plate can be magnetically fixed to the mounting frame. Specifically, as an example, both the cover plate and the mounting frame are provided with four magnet blocks.

[0029] In some specific implementation methods, refer to Figure 3 and Figure 4 The upper part of the mounting frame 4 is provided with a positioning step 42, the outline of which is adapted to the outer perimeter of the cover plate 5. Thus, after the cover plate is installed in place, its upper surface is basically flush with the upper surface of the mounting frame, resulting in a neater visual appearance.

[0030] As an improved implementation method, such as Figure 3 As shown, a sealing gasket 6 is provided between the mounting frame 4 and the cover plate 5, thereby improving the airtightness between the mounting frame and the cover plate. More specifically, as an example, the sealing gasket 6 is fixed to the lower surface of the cover plate 5 by adhesive bonding.

[0031] refer to Figures 1-6 In some embodiments, the cover plate 5 has a through observation port in the middle, and a light-transmitting plate 52 is installed in the observation port. This allows sunlight to enter the placement chamber through the light-transmitting plate, providing lighting conditions for microbial fermentation. Specifically, a light-shielding plate 7 for covering the observation port is slidably installed on the upper surface of the cover plate 5, and the upper surface of the light-shielding plate 7 has a push-pull handle 71. Due to the structure of the light-shielding plate, which is slidably installed, the light-shielding adjustment can be completed simply by pushing and pulling left and right, making it easy to operate and simple in structure, reducing manufacturing difficulty and cost.

[0032] In some specific implementation methods, refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 The number of light-shielding plates 7 is two, and the two light-shielding plates 7 are symmetrically distributed above the observation port. The upper surface of the cover plate 5 is provided with two inverted L-shaped guide strips 53 located on both sides of the light-shielding plates 7. A guide groove 54 for sliding the light-shielding plates 7 is formed between the guide strips 53 and the cover plate 5.

[0033] In a preferred embodiment, the cover plate 5 is an opaque plastic plate, and the light-transmitting plate 7 is a transparent polycarbonate plate.

[0034] refer to Figures 1-6 As an improved implementation, to prevent accidental deformation of the telescopic support cylinder due to lack of collision, the side wall of the fermentation tank 1 is provided with at least one recess 12 distributed along the height direction. A support plate 43 corresponding to the recess 12 is connected to the outer periphery of the mounting frame 4. A metal telescopic rod 8 for reinforcing support is connected between the bottom surface of the recess 12 and the bottom surface of the support plate 43. The metal telescopic rod 8 includes several metal tubes 81 nested together from the inside out, with a protruding ring 82 between adjacent metal tubes 81 for maintaining elastic engagement. By adding the metal telescopic rod as an auxiliary support, the support stability of the mounting frame and cover plate can be greatly improved. As an example, four metal telescopic rods 8 are provided, located at the four right angles of the fermentation tank 1, thereby providing more stable support for the mounting frame and playing a reinforcing role.

[0035] Furthermore, a temperature control device and temperature sensor can be installed on the bottom wall of the fermentation chamber for temperature regulation. The temperature control device includes a PTC heating element and a semiconductor cooler. A control circuit board is located at the bottom of the fermentation chamber and is connected to a power cord. A touch panel with operation buttons is installed on the side wall of the fermentation chamber. The PTC heating element, semiconductor cooler, temperature sensor, and touch panel are electrically connected to the control circuit board. Through the established temperature control device, the temperature of the fermentation process can be controlled.

[0036] refer to Figures 1-6 The adjustment operation instructions for this utility model are as follows:

[0037] First, according to the height specifications of the microbial fermentation culture vessel, grasp the mounting frame 4 and pull it upwards to the appropriate height. At this time, the telescopic support cylinder 3 is pulled out and unfolded, providing support through its own material toughness. Simultaneously, the metal telescopic rod 8 provides additional reinforcing support, ensuring that the mounting frame 4 will not easily collapse or fall. Next, place the microbial fermentation culture vessel containing the fermentation material onto the bracket 2. Then, use magnetic attraction to magnetically fix the cover plate 5 to the positioning step 42 on the mounting frame 4. When sunlight is needed, the light-shielding plate 7 can be pushed to both sides by grasping the push-pull handle 71, thus exposing the light-transmitting plate 52, allowing sunlight to irradiate the internal microbial fermentation culture vessel through the light-transmitting plate 52. Furthermore, the opening and closing degree between the two light-shielding plates 7 can be easily adjusted according to the light intensity, thereby achieving the purpose of light regulation.

[0038] The above embodiments are merely illustrative of the concept and technical solution of this utility model, and are not intended to limit this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
