Description

Technical Field

[0001] This utility model relates to the field of microbial preparation technology, and in particular to a microbial solid-state fermentation culture tray. Background Technology

[0002] In existing technologies, microbial fertilizers are typically prepared by fermentation using solid culture media. Specifically, the prepared solid culture medium is placed in a closed or semi-closed fermentation container, and under controlled temperature and humidity conditions, it is cultured for a certain period of time, allowing beneficial microorganisms to multiply in large numbers and produce corresponding metabolites, thereby obtaining microbial fertilizers with functions such as soil improvement, inhibition of soil-borne diseases, and promotion of crop growth.

[0003] However, the current fermentation trays have a simple structure, making water replenishment control inconvenient and resulting in rapid moisture loss. Furthermore, existing equipment often uses fixed-volume fermentation chambers, which can only hold a single culture medium ratio, making it impossible to simultaneously process multiple formulations or different fermentation conditions within the same device. In addition, the space capacity of each fermentation unit is not adjustable, hindering flexible adjustments based on actual production needs and limiting the equipment's applicability and process adaptability. Therefore, there is an urgent need to develop a microbial fertilizer fermentation device with a reasonable structure, convenient water replenishment, flexible space configuration, and applicability to various culture medium ratios, achieving technological iteration to overcome the aforementioned shortcomings of existing technologies.

[0019] Example 1: like Figure 1-6 In the microbial solid-state fermentation culture tray, there is a fermentation tray 1. The bottom of the fermentation tray 1 is provided with a humidifying structure. The humidifying structure supports a material support plate 2 that cooperates with the fermentation tray 1. The material support plate 2 is provided with multiple sets of first through holes 3. Each set of first through holes 3 penetrates the upper and lower surfaces of the material support plate 2, so that the culture medium above the material support plate 2 can form effective contact with the humidifying structure below, and ensure that water can penetrate evenly into the interior of the culture medium.

[0020] The humidification structure includes a ring plate 4 located at the bottom of the fermentation pan 1. The ring plate 4 is arranged circumferentially along the inner wall of the fermentation pan 1 to provide stable support for the material support plate 2. The ring plate 4 has multiple sets of second through holes 5, which penetrate the inner and outer walls of the ring plate 4, allowing water on the inner side of the ring plate 4 to diffuse towards the outer material support plate 2. The ring plate 4 is fixedly connected to the positioning column 6 by multiple diversion seats 8. The diversion seats 8 are evenly distributed circumferentially along the positioning column 6. The positioning column 6 is detachably assembled and disassembled with the material support plate 2. The positioning column 6 has a water filling chamber 7, which extends axially along the positioning column 6 and has an opening at the top for water filling. The diversion seats 8 have multiple sets of water guiding grooves 9 that communicate with the water filling chamber 7. The water guiding grooves 9 extend radially along the diversion seats 8 to divert water in the water filling chamber 7 towards the ring plate 4. A water storage unit 20 is provided in the gap between adjacent diversion seats 8 and the ring plate 4. The water storage unit 20 is used to store water and release it slowly.

[0021] In a preferred embodiment, the multiple sets of first through holes 3 are evenly arranged in a ring on the material support plate 2 near the outer edge. The positions of the annularly arranged first through holes 3 correspond to the positions of the second through holes 5 on the ring plate 4, ensuring that water can stably permeate from the side of the ring plate 4 to the culture medium on the material support plate 2, and avoiding local insufficient water supply to the culture medium.

[0022] In a preferred embodiment, the multiple sets of second through holes 5 are evenly distributed near the upper edge of the ring plate 4. This position allows the water in the water storage unit 20 to quickly come into contact with the bottom of the material support plate 2 when it diffuses upward under gravity and capillary action, while preventing water accumulation and backflow when there is too much water in the water storage unit 20.

[0023] In a preferred embodiment, the diversion seat 8 is provided with a first mounting groove 10 and a second mounting groove 11. The first mounting groove 10 and the second mounting groove 11 are distributed vertically along the height direction of the diversion seat 8. A first annular groove 12 is installed on the first mounting groove 10. The first annular groove 12 is an annular groove structure. Multiple sets of first water-permeable holes 13 are evenly distributed on the bottom of the groove. The first water-permeable holes 13 penetrate the bottom of the groove and communicate with the area of ​​the water storage unit 20 below. A second annular groove 14 is installed on the second mounting groove 11. The second annular groove 14 is also an annular groove structure. Multiple sets of second water-permeable holes 15 are evenly distributed on the bottom of the groove. The second water-permeable holes 15 are connected to the area of ​​the water storage unit 20. By setting up the upper and lower annular grooves, the water is released in layers, and the uniformity of water diffusion is improved.

[0024] In a preferred embodiment, the contact positions of the first annular groove 12 and the water guide groove 9 are provided with openings, the opening size of which is adapted to the width of the water guide groove 9, to ensure that the water in the water guide groove 9 can flow completely into the first annular groove 12 and to prevent water from stagnating in the water guide groove 9.

[0025] In a preferred embodiment, the contact position between the second annular groove 14 and the water guiding groove 9 is provided with an opening, which corresponds to the opening structure of the first annular groove 12, so that the water in the water guiding groove 9 can be simultaneously diverted to the upper and lower annular grooves, thereby achieving rapid water distribution.

[0026] In a preferred embodiment, the outer wall of the positioning post 6 is provided with a communicating opening groove 17 and a limiting rotating groove 16. The opening groove 17 is opened along the axial direction of the positioning post 6, and the limiting rotating groove 16 extends circumferentially along the positioning post 6. The limiting rotating groove 16 cooperates with the limiting mounting head 19 provided on the partition plate 18. During assembly, the limiting mounting head 19 is aligned with the opening groove 17 and inserted, and then the positioning post 6 is rotated so that the limiting mounting head 19 is engaged in the limiting rotating groove 16, thereby achieving a stable connection between the material support plate 2 and the positioning post 6. During disassembly, the positioning post 6 is rotated in the opposite direction so that the limiting mounting head 19 is disengaged along the opening groove 17, making the operation convenient and efficient.

[0027] Example 2: like Figure 1-6 The working principle of this utility model is as follows: First, according to the fermentation requirements, the material tray 2 and the positioning column 6 are assembled and fixed. Then, the partition 18 is installed through the opening groove 17 and the limiting rotation groove 16. The pre-proportioned solid culture medium is evenly spread on the material tray 2 in each area. Water required for fermentation is injected through the water filling chamber 7 at the top of the positioning column 6. The water flows downward along the water filling chamber 7 and enters the water guide groove 9 on each distribution seat 8. It then flows into the first ring groove 12 and the second ring groove 14 through the openings at both ends of the water guide groove 9. Subsequently, the water permeates evenly into the water storage unit 20 between the adjacent distribution seat 8 and the ring plate 4 through the first water permeation hole 13 of the first ring groove 12 and the second water permeation hole 15 of the second ring groove 14. The water storage unit 20 stores the water and releases it slowly. The water released by the water storage unit 20 diffuses upward through the second through hole 5 on the ring plate 4, and at the same time permeates to the bottom of the culture medium through the first through hole 3 on the material support plate 2, so as to achieve uniform water replenishment of the culture medium. If insufficient humidity is detected during fermentation, water can be continuously added through the water inlet 7 to prevent rapid water loss and ensure a stable humidity environment required for microbial growth.

[0028] The advantages of this invention are: convenient water replenishment, water can be stored and slowly released to meet the humidity requirements of the fermentation process; flexible space configuration and distribution, suitable for use with different components of culture media; reasonable and simple overall structure of the device, convenient and flexible operation, and strong practicality.
