Description

Technical Field

[0001] This invention relates to the field of microbial culture technology, specifically to a culture device for morel mushroom strains. Background Technology

[0002] Morel spawn refers to the collective term for artificially isolated, purified, and cultivated active morel mycelia and their growth substrates, serving as the core propagation material for the artificial cultivation of morels. Its applications are wide-ranging, including large-scale artificial cultivation to achieve high-quality and high-yield production, scientific research for variety improvement and growth mechanism studies, and adaptation to inoculant production. Wild morel mushrooms are scarce and require demanding growing conditions, resulting in extremely low natural reproduction efficiency, which cannot meet market and research needs. Artificial cultivation allows for precise control of temperature, humidity, and nutrients, enabling pure culture and propagation of the strain, ensuring its purity, activity, and stability, avoiding contamination by other microorganisms, providing a sufficient supply of high-quality germplasm for artificial cultivation, and supporting the development of variety optimization and efficient cultivation technologies. This is a key prerequisite for the industrialization of morel mushrooms. Currently, morel mushroom cultivation mostly employs the traditional method of "directly placing the petri dishes in an incubator," relying on the overall temperature and humidity control of the incubator and lacking targeted local environmental optimization design. This method has significant drawbacks: when the petri dishes are placed statically, temperature, humidity, and oxygen levels easily stratify at the top, middle, and bottom, leading to uneven mycelial growth; gas circulation within the incubator relies on natural diffusion, which cannot precisely target the area around each petri dish, resulting in low efficiency for the spores to obtain nutrients and oxygen. Therefore, it is necessary to propose a new cultivation device for morel mushroom spores. Summary of the Invention

[0003] To address the problems in the prior art, the present invention provides a cultivation device for morel mushroom strains.

[0004] The technical solution adopted by this invention to solve its technical problem is: a cultivation device for morel mushroom strains, comprising an incubator and a cabinet door hinged to the opening end of the incubator. The incubator has multiple sets of placement plates that slide and snap together at its inner end. Each placement plate has a placement groove at its top. Several movable support plates are provided at the inner edge of each placement groove. Each movable support plate has an air inlet hole through its side wall and a spiral groove on its inner surface. An installation frame is installed at the bottom of the placement plate. Several rotating shafts are rotatably snapped together at the edge between the installation frame and the placement plate. Each rotating shaft is connected to a movable support plate. Two pulleys of different heights are fixedly connected to the shaft wall of each rotating shaft. A transmission belt is connected between several adjacent pulleys. A servo motor is installed at the inner edge of the installation frame, and the output end of the servo motor is connected to one of the rotating shafts. An air storage box is installed inside the mounting frame, and a pump body is installed on the outer wall of the air storage box. An air guide pipe is fixedly connected to the output end of the pump body, and the input end of the pump body is connected through to the air storage box. A frame is installed on the inner wall of the placement slot, and the air guide pipes are distributed inside the frame. Several nozzles are embedded in the wall of each air guide pipe.

[0005] Specifically, a base is installed at the bottom of the incubator.

[0006] Specifically, a transparent observation window is embedded in the middle of the cabinet door, a handle is installed on the outer edge of the cabinet door, and a pull-out groove is opened at the bottom edge of the mounting frame.

[0007] Specifically, several static bearing plates are installed at the bottom of the placement groove, which is located in the middle of the moving bearing plate, and rubber gaskets are fixedly connected to the bottom of both the static bearing plates and the moving bearing plate.

[0008] Specifically, the air inlets and nozzles are both distributed at an angle, and the air inlets and nozzles are at the same level.

[0009] Specifically, the two adjacent pulleys are positioned at different heights.

[0010] Specifically, an inflation tube is embedded at the bottom of the gas storage tank and extends to the bottom of the mounting frame. A sealing plug is snapped into the inner end of the inflation tube.

[0011] The first beneficial effect of this invention is that it achieves smooth rotation of the dynamic support plate through a linkage transmission structure of "servo motor + multi-height pulleys + transmission belt". Combined with the fixed design of the static support plate, it can simultaneously meet the needs of dynamic and static cultivation, improving the efficiency of obtaining bacteria and oxygen nutrients from the culture dish. Rubber pads effectively buffer rotational vibrations, preventing culture dish slippage or damage to the bacteria. The design of pulleys with different heights prevents the transmission belt from tangling and interfering, ensuring transmission stability. The layered placement plate and pull-out design enable batch cultivation of bacteria and facilitate the removal and placement of culture dishes and equipment maintenance, significantly improving the convenience and efficiency of cultivation operations, making it suitable for laboratory and small-scale production scenarios.

[0012] The second beneficial effect of this invention is its innovative integration of the spiral groove and air inlet structure of the gas storage tank and the moving support plate. Inert gas is precisely delivered into the support plate via a directional nozzle, forming a stable air curtain barrier that prevents disordered intrusion of external air caused by vibration. The gas spreads and rises evenly along the spiral groove, creating a clean and stable inert microenvironment that inhibits the growth of miscellaneous bacteria and prevents gas disturbances from affecting bacterial growth. The coordinated gas path and transmission structure completely solve the pollution risks and environmental unevenness problems caused by vibration in traditional cultivation, ensuring the purity and activity of the bacterial strain and improving growth uniformity.

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-7 As shown, the present invention provides the following technical solution: Example 1: A cultivation device for morel mushroom strain, including an incubator 1 and a cabinet door 2 hinged to the opening end of the incubator 1. Multiple sets of placement plates 11 are slidably connected to the inner end of the incubator 1. Placement slots 101 are opened at the top of the placement plates 11. A base 10 is installed at the bottom end of the incubator 1. A transparent observation window 21 is embedded in the middle of the cabinet door 2. A handle is installed on the outer edge of the cabinet door 2.

[0018] Among them, the incubator 1 is a commercially available incubator that uses built-in heating and cooling modules and a spray / humidification system, combined with temperature and humidity sensor feedback control, to keep the temperature and humidity inside the chamber within the set range.

[0019] In use, first open cabinet door 2 using the handle on the outer wall of the door. Place the inoculated morel mushroom culture dish stably into the placement slot 101 at the top of the placement plate 11. Each placement plate 11 can hold multiple culture dishes in layers, enabling batch cultivation. After closing cabinet door 2, maintain a suitable growth environment using the basic temperature and humidity control functions of the incubator 1. The growth status of the culture can be observed in real time through the transparent observation window 21 in the middle of cabinet door 2, eliminating the need for frequent opening of cabinet door 2 and reducing the risk of contamination. The base 10 provides stable support for the incubator 1, and the placement plate 11 can be slidably pulled out for easy removal and replacement of culture dishes, suitable for small-scale culture propagation scenarios in laboratories.

[0020] Example 2: The technical solution of this example, which differs from Example 1, includes: multiple sets of placement plates 11 are slidably engaged at the inner end of the incubator 1; a placement groove 101 is provided at the top of the placement plate 11; several movable bearing plates 12 are provided at the inner edge of the placement groove 101; an installation frame 3 is installed at the bottom of the placement plate 11; several rotating shafts 31 are rotatably engaged at the edge between the installation frame 3 and the placement plate 11; and each rotating shaft 31 is connected to a movable bearing plate 12; two pulleys 32 at different heights are fixedly connected to the shaft wall of each rotating shaft 31. A drive belt 33 is connected between several adjacent pulleys 32. A servo motor 34 is installed at the inner edge of the mounting frame 3, and the output end of the servo motor 34 is connected to one of the rotating shafts 31. A pull-out groove 301 is provided at the bottom edge of the mounting frame 3. Several static bearing plates 13 are installed in the bottom of the placement groove 101, which is located in the middle of the moving bearing plate 12. Rubber pads 120 are fixedly connected to the bottom of both the static bearing plate 13 and the moving bearing plate 12. The pulleys 32 are set at different heights.

[0021] In use, the culture dishes are placed in the moving support plate 12 and the stationary support plate 13 respectively. The rubber pads 120 can buffer vibration and prevent the culture dishes from sliding. The servo motor 34 is started, and its output drives the connected rotating shaft 31 to rotate. Through the linkage of pulleys 32 at different heights on the rotating shaft 31 and the transmission belt 33, all rotating shafts 31 are driven to rotate synchronously, thereby driving the moving support plate 12 to rotate (the stationary support plate 13 remains fixed to adapt to different culture needs). The height difference design of adjacent pulleys 32 avoids the transmission belt 33 from tangling and interfering, ensuring stable transmission. When the moving support plate 12 rotates, the pull-out groove 301 facilitates the removal of the placement plate 11 and the mounting frame 3 for subsequent maintenance.

[0022] Example 3: The technical solution of this example, which differs from that of Example 1, includes: an air storage box 4 is installed inside the mounting frame 3, a pump body 41 is installed on the outer wall of the air storage box 4, an air guide pipe 42 is fixedly connected to the output end of the pump body 41, and the input end of the pump body 41 is connected through to the air storage box 4, a frame 43 is installed on the inner wall of the placement slot 101, and the air guide pipes 42 are distributed inside the frame 43, and several nozzles 44 are embedded in the wall of the air guide pipes 42, the air inlet 102 and the nozzles 44 are distributed at an angle, and the air inlet 102 and the nozzles 44 are at the same level, an inflation pipe 45 is embedded in the bottom of the air storage box 4, and the inflation pipe 45 extends to the bottom of the mounting frame 3, and a sealing plug is snapped into the inner end of the inflation pipe 45, an air inlet 102 is opened through the side wall of the moving bearing plate 12, and a spiral groove 103 is opened on the inner surface of the moving bearing plate 12.

[0023] The pump body 41 and the servo motor 34 are both electrically connected through an external controller.

[0024] In use, first remove the sealing plug inside the inflation tube 45, and then inject sterile inert gas (such as nitrogen) into the gas storage tank 4 through the inflation tube 45. After filling, reseal the inflation tube 45 with the sealing plug to ensure that the gas in the gas storage tank 4 is clean and free of bacteria. After starting the pump body 41, the inert gas in the gas storage tank 4 is transported to the frame 43 through the air guide tube 42 and sprayed out directionally by several inclined nozzles 44.

[0025] Because the nozzle 44 and the air inlet 102 on the side wall of the moving support plate 12 are at the same horizontal height, the inert gas can be precisely aligned with the air inlet 102 and quickly enter the interior of the moving support plate 12. When the moving support plate 12 vibrates due to the rotation of the transmission mechanism, the air inside the chamber is prone to try to invade the culture dish due to disturbance. The continuously sprayed inert gas can form an "air curtain barrier" to prevent the disorderly infiltration of external air. At the same time, the stability of the inert gas buffers the impact of vibration on the gas environment.

[0026] The inert gas entering the dynamic support plate 12 spreads and rises evenly along the spiral groove 103 on the inner wall, forming a stable inert microenvironment around the petri dish. This not only avoids gas disturbance caused by vibration, but also inhibits the growth of miscellaneous bacteria, providing a stable and clean growth environment for morel mushroom strains and ensuring the activity and uniformity of the strains.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
