Description

Technical Field

[0001] This utility model relates to the field of fungal cultivation technology, and in particular to a microecological fungal cultivation cabinet. Background Technology

[0002] High-end edible and medicinal fungi (such as matsutake and reishi) have long relied on wild resources due to their unique nutritional value and market demand. Wild fungi have demanding growth environments, are highly seasonal, and have unstable yields, making it difficult to meet large-scale market demands. To overcome resource limitations, the industry has explored indoor artificial cultivation techniques, primarily using dark greenhouses to simulate natural growth conditions. However, greenhouse cultivation has significant limitations: fungal growth requires precise control of temperature, humidity, gas composition (such as CO2 / O2), and nutrient supply. Traditional greenhouses rely on manual, experience-based operation, resulting in large dynamic fluctuations in environmental parameters. This leads to uneven mycelial development, uncontrollable fruiting cycles, and inconsistent finished product morphology and quality, making continuous and stable production throughout the year impossible and hindering the industry's modernization.

[0012] Furthermore, the vertical breeding rack also includes a second column arranged parallel to the first column. The two ends of the second column are fixed to the two connecting arms. A track wheel is rotatably installed on the upper end of the second column, and an upper track that cooperates with the track wheel is fixed on the top of the breeding chamber.

[0013] Furthermore, the lower end of the second column is connected by a threaded connection to an adjustable limiter. The bottom of the breeding chamber is fixed with a lower support rail corresponding to the position of the limiter. An arc groove is formed on the upper surface of the lower support rail. A support ball is rotatably installed between the limiter and the lower support rail.

[0014] Furthermore, the nutrient solution dispensing device includes a nutrient solution tank located in the control room and a dispenser located in the breeding room. The dispenser and the nutrient solution tank are connected by a pipeline, and a first liquid pump is installed on the pipeline connecting the nutrient solution tank and the dispenser.

[0015] Furthermore, the automatic mushroom stick handling device includes a protective column vertically installed in the cultivation chamber.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] like Figures 1-5As shown, a microbial culture cabinet includes a movable cabinet 1, which is preferably modified from a standard shipping container for easy transportation, stacking, and large-scale deployment. Its dimensions are a standard 40-foot high cube container (internal dimensions approximately 11.62m * 2.29m * 2.50m), with an internal volume of approximately 67 cubic meters, offering high space utilization and site adaptability. The movable cabinet 1 and the first cabinet door 21 are equipped with an insulation layer made of polyurethane foam with a thickness ≥80mm to reduce temperature interaction between the inside and outside. The interior of the movable cabinet 1 is divided into a culture chamber 2 and a control chamber 3 by a partition. This partition structure facilitates physical isolation between the environmental control unit and the culture area, simplifying management and maintenance while preventing equipment operation from interfering with fungal growth. The first cabinet door 21 is installed at the end of the culture chamber 2 furthest from the control chamber 3, and a second cabinet door 31 is installed at the end of the control chamber 3 furthest from the culture chamber 2. The dual-door independent design allows operators to enter the breeding area or equipment maintenance area separately, reducing external environmental interference with the stable internal climate of the breeding chamber and facilitating assembly line operations. A lower annular drive chain 4 is fixed at the bottom of the breeding chamber 2, and an upper annular drive chain 5 is installed at the top of the breeding chamber 2 corresponding to the lower annular drive chain 4. Both the lower and upper annular drive chains 4 and 5 are driven by stepper motors and start and stop synchronously. Several vertical breeding racks 6 for cultivating fungi are fixed at equal intervals between the lower and upper annular drive chains 4 and 5. The dual-drive chain structure provides uniform traction, ensuring the smooth and cyclical movement of the vertical breeding racks 6. To avoid jamming or tilting problems that may be caused by unilateral drive, the vertical cultivation rack 6 moves continuously along the circular track under the drive chain, forming a dynamic "cultivation assembly line". This allows the mushroom logs to pass through stations for feeding, growth, and harvesting in sequence, greatly improving production efficiency and space utilization. An automatic mushroom log loading and unloading device 8 is fixed at one end of the cultivation chamber 2 near the first cabinet door 21, and a nutrient solution loading device 7 is installed at the other end of the cultivation chamber 2 near the control room 3. By arranging the loading and unloading devices at opposite ends of the circular path, a streamlined operation for mushroom log loading and nutrient replenishment can be achieved, improving operational efficiency and space utilization. 6. As the lower ring drive chain 4 moves, it passes through the working range of the nutrient solution adding device 7 and the automatic mushroom stick picking and placing device 8. Through the continuous operation of the ring drive chain, nutrient solution can be automatically added to all mushroom sticks at timed and quantitative intervals, and batch automated picking and placing operations can be supported, significantly reducing manual intervention. It is particularly suitable for the large-scale cultivation of high-end edible and medicinal fungi such as matsutake and Ganoderma. An environmental data acquisition module 9 for monitoring internal air data is installed on the inner wall of the cultivation chamber 2. An air supply belt 16 is installed on the top of the cultivation chamber 2. Several ventilation holes are arrayed at equal intervals along the length direction on the side wall and bottom of the air supply belt 16. The diameter of the ventilation holes on the side wall of the air supply belt 16 is 0.The airflow is 5mm thick and tilted downwards at 45° to ensure rapid airflow coverage of the entire breeding chamber 2. A static pressure box 12, connected to the air supply duct 16, is installed above the breeding chamber 2. The static pressure box 12 evenly distributes the airflow, ensuring uniform airflow from the air supply duct 16 and avoiding localized temperature, humidity, or gas concentration deviations, thus ensuring consistent microenvironmental parameters throughout the chamber. A hot and cold air blower 15, connected to the static pressure box 12 via pipes, is installed above the breeding chamber 2. A carbon dioxide removal machine 10 and an aerator 11, which exchange air with the interior of the breeding chamber 2, are installed inside the control room 3.

[0038] The carbon dioxide removal unit 10 is used to maintain a suitable carbon dioxide concentration inside the cultivation chamber. Edible fungi have different CO2 requirements at different growth stages. For example: during the mycelial growth stage, higher concentrations of CO2 (usually 5000-20000 ppm or even higher) stimulate mycelial growth. During the fruiting body (fruiting) stage, lower concentrations of CO2 (usually below 1000-2000 ppm) are required. Excessive CO2 can lead to deformed fruiting bodies, long stems and small caps, and reduced yield and quality. The CO2-rich air inside the cultivation chamber 2 is drawn into the carbon dioxide removal unit 10 by a fan. The air passes through a reaction bed / tower containing a solid chemical adsorbent (such as lithium hydroxide or soda lime) or a liquid absorbent (such as potassium hydroxide solution). CO2 undergoes an irreversible or reversible chemical reaction with the adsorbent and is firmly locked within it. The purified air, with a significantly reduced CO2 content, is then blown back into the cultivation chamber 2. When the adsorbent becomes saturated, it loses its adsorption capacity and needs to be regenerated. This is done by heating to break the chemical bonds, releasing high-purity CO2, which is then discharged from the system through the exhaust pipe. The regenerated adsorbent regains its activity and can be put back into adsorption work. This process is usually carried out automatically.

[0039] Aerator 11 is used to increase the oxygen concentration inside the breeding tank to meet the needs of fungal respiration and maintain normal metabolism. Sufficient oxygen is crucial for robust mycelial growth and prevention of anaerobic bacterial contamination. Aerator 11 uses a "pressure swing adsorption method" to increase the oxygen content in the air. Air from inside the breeding tank 2 is drawn in and compressed by the compressor within aerator 11. The compressed air is then cooled and filtered to remove oil, water, and other particulate impurities. The treated compressed air is then introduced into an adsorption tower containing zeolite molecular sieves. Zeolite molecular sieves are materials with a microporous structure, whose adsorption capacity for nitrogen is far stronger than its adsorption capacity for oxygen. When compressed air passes through the molecular sieve, nitrogen, carbon dioxide, water vapor, and other components are selectively adsorbed, while oxygen and the inert gas argon pass through, thus producing oxygen-enriched air (typically with a purity of 90-95%).

[0040] The industrial control host 14 receives real-time oxygen and CO2 concentration data from the environmental data acquisition module 9. When the CO2 concentration exceeds a set threshold (e.g., 800 ppm for the fruiting body stage), the carbon dioxide removal machine 10 automatically starts. Once the concentration drops to the target range, the equipment stops or reduces its power, achieving precise and energy-saving closed-loop control. When the oxygen concentration is lower than the set value, the oxygen-enriched air generated by the aerator 11 is sent to the static pressure box 12 through pipelines, mixed with temperature- and humidity-controlled air, and then evenly delivered to the cultivation room 2. The industrial control host 14 intelligently controls the start / stop and output of the aerator 11 based on oxygen sensor data to ensure that the oxygen concentration remains stable within the optimal range. By integrating temperature control, carbon dioxide removal, and oxygen supply equipment, the optimal gaseous environment for fungal growth can be accurately simulated, improving mycelial development quality, fruiting consistency, and yield.

[0041] In another preferred embodiment of this utility model, the environmental data acquisition module 9 includes a barometer (TEConnectivity MS5611-01BA03), an oxygen concentration sensor (City Technology (Honeywell) 4OXV), a carbon dioxide concentration sensor (Sensirion SCD40), and a temperature and humidity sensor (Sensirion SHT45). The environmental data acquisition module 9 collects data including air pressure, oxygen concentration, carbon dioxide concentration, temperature, and humidity. The synchronous monitoring of multiple parameters provides real-time data support for the environmental control system and is a key foundation for achieving accurate environmental simulation. By connecting to the industrial control host 14 of the Internet of Things, the module realizes real-time data acquisition, analysis, and command issuance, forming a closed-loop control.

[0042] In another preferred embodiment of this utility model, the air outlets of the carbon dioxide removal machine 10 and the aerator 11 are connected to the static pressure box 12 via air supply pipes. An atomizer 13 is installed at one end of the air supply pipe near the static pressure box 12. This design allows the temperature, air, and humidity control functions to be initially mixed within the static pressure box 12, improving the uniformity of parameters of the air supplied to the breeding room. A water storage tank 17 is installed in the control room 3, and the water storage tank 17 is connected to the atomizer 13. A second liquid pump 18 is installed on the pipeline connecting the water storage tank 17 and the atomizer 13. The atomizer 13 can atomize water into micron-sized particles and diffuse them with the airflow to achieve efficient humidification. At the same time, it avoids direct spraying of liquid water onto the mushroom sticks, which could lead to contamination or over-wetting. The capacity of the water storage tank 17 is not less than 1 m³, which needs to meet the requirements of long-term automatic operation of the system and reduce frequent water replenishment.

[0043] In another preferred embodiment of this utility model, an industrial control host 14 is fixed in the control room 3 and electrically connected to the lower ring drive chain 4, the upper ring drive chain 5, the nutrient solution injection device 7, the automatic mushroom stick picking and placing device 8, the environmental data acquisition module 9, and the hot and cold air fan 15. The industrial control host 14 automatically regulates the air pressure, temperature and humidity, oxygen concentration and carbon dioxide concentration in the breeding room 2 according to the data fed back by the environmental data acquisition module 9. The industrial control host 14 has a built-in STC89C51 microcontroller and an IoT-enabled WiFi communication module, and an external touch screen. The STC89C51 is an ISP (In-System Programming) chip with an 8051 core, with a maximum operating clock frequency of 80MHz. It contains 8K bytes of Flash read-only program memory that can be repeatedly erased and rewritten 1000 times. The device is compatible with the standard MCS-51 instruction system and the 80C51 pin structure. The chip integrates a general-purpose 8-bit central processing unit and an ISP Flash memory unit. The WiFi communication module uses the ESP-07 WiFi module, which uses the ESP8266 chip. This module integrates a 32-bit microprocessor in a small package and supports Wi-Fi MAC / BB / RF / PA / LNA. It supports the standard IEEE 80211b / g / n protocol and a complete TCP / IP protocol stack. Using this module, developers can connect their designed systems to the network or establish independent network controllers. The industrial control host 14 coordinates the closed-loop control of all electric components' actions and environmental parameters, serving as the core for achieving automated operation of the entire system. Data from the industrial control host 14 can be transmitted in real-time to the remote monitoring and management center via the WiFi communication module, allowing for remote supervision by personnel at the center. Combined with IoT technology, it supports remote monitoring and intelligent management, enabling unattended operation.

[0044] As another preferred embodiment of this utility model, an ventilation fan 19 for ventilating the control room 3 is installed on the upper surface of the movable cabinet 1. The ventilation fan 19 is electrically connected to the industrial control host 14. The heat dissipation of equipment (such as the industrial control host, carbon dioxide removal machine, aerator, etc.) in the control room 3 may affect the local temperature. Active ventilation can ensure the stable operating environment of the electrical control equipment and extend the equipment life. The start and stop of the ventilation fan 19 are automatically controlled by the industrial control host 14 according to the temperature of the control room 3 (a temperature sensor electrically connected to the industrial control host 14 is installed in the control room 3).

[0045] As another preferred embodiment of this utility model, the first cabinet door 21 is an insulated cabinet door, and a sealing ring is installed on the edge of the first cabinet door 21. The heat preservation and sealing design can effectively reduce the heat exchange and gas exchange between the breeding room 2 and the external environment, which is conducive to maintaining the stability of internal environmental parameters and reducing energy consumption. The sealing ring is preferably a Y-type negative pressure sealing ring to prevent pressure loss.

[0046] As another preferred embodiment of this utility model, such as Figure 6 As shown, the vertical cultivation rack 6 includes a first column 61 vertically positioned between the lower annular drive chain 4 and the upper annular drive chain 5. The two ends of the first column 61 are fixed to the lower annular drive chain 4 and the upper annular drive chain 5 respectively via connecting arms 63. Several mushroom stick placement trays 64, each containing mushroom sticks, are fixed at equal intervals in the vertical direction on the outer wall of the first column 61. The multi-layer mushroom stick placement trays 64 make full use of vertical space, greatly increasing the planting capacity per unit area, which is particularly suitable for indoor cultivation scenarios with limited space. The mushroom stick placement trays 64 have brackets formed inside for placing mushroom sticks, so that the mushroom sticks are suspended after being placed in the tray, which facilitates ventilation. Each mushroom stick placement tray 64 can hold 1-3 mushroom sticks.

[0047] As another preferred embodiment of this utility model, the vertical breeding rack 6 also includes a second column 62 arranged parallel to the first column 61. The two ends of the second column 62 are fixed to two connecting arms 63. A track wheel 66 is rotatably installed on the upper end of the second column 62. The second column 62 and the track wheel 66 constitute an upper auxiliary support and guide structure, which can enhance the overall rigidity of the breeding rack, prevent swaying or deformation due to its height, and ensure smooth operation. An upper track 65 is fixed at the top of the breeding chamber 2 and is installed in conjunction with the track wheel 66. The upper track 65 is located on the side of the track wheel 66 near the upper annular drive chain 5. The upper track 65 and the track wheel 66 cooperate to constrain the movement trajectory of the upper part of the breeding rack, ensuring that it remains vertically stable during the annular movement, avoiding interference with surrounding devices, and avoiding tilting caused by excessive weight on one side. The track can be made of wear-resistant steel, which is durable.

[0048] As another preferred embodiment of this utility model, such as Figure 7 As shown, the lower end of the second column 62 is connected by a threaded connection to a height-adjustable limiter 68. The threaded adjustment structure can precisely adjust the height of the limiter 68, compensate for manufacturing and installation errors, and ensure good contact between the track wheels of each breeding rack and the upper track. The bottom of the breeding chamber 2 is fixed with a lower support track 67 corresponding to the position of the limiter 68. The upper surface of the lower support track 67 is formed with an arc groove. A support ball 69 is rotatably installed between the limiter 68 and the lower support track 67. The lower end of the limiter 68 is formed with a conical cap-shaped cover that covers the upper end of the support ball 69 to prevent the support ball 69 from falling off. The support ball 69 and the arc groove form a bottom rolling support structure, which greatly reduces the moving friction resistance, reduces the load on the drive chain, and can adapt to the slight deflection generated when the breeding rack travels on a curve, thereby improving the reliability and lifespan of the system.

[0049] As another preferred embodiment of this utility model, such as Figure 1 , Figure 4As shown, the nutrient solution dispensing device 7 includes a nutrient solution tank 71 located in the control room 3 and a dispenser 73 located in the cultivation room 2. The nutrient solution tank 71 is externally mounted for easy manual replenishment of nutrient solution, while the dispenser 73 is internally mounted for precise alignment with the moving mushroom substrate tray 64. The dispenser 73 is connected to the nutrient solution tank 71 via a pipe. A first liquid pump 72 is installed on the pipe connecting the nutrient solution tank 71 and the dispenser 73. The liquid pump provides the power for delivery and can achieve quantitative pumping to ensure that each mushroom substrate tray 64 receives an equal amount of nutrient solution, thus ensuring uniform mycelial growth. The dispenser 73 has a horizontally positioned extension pipe above each layer of mushroom substrate tray 64 for easy coverage of the trays. The dispenser 73 can be used for drip irrigation or spraying, and the dispensing amount and timing can be precisely controlled according to the growth stage and needs of the fungi.

[0050] As another preferred embodiment of this utility model, such as Figure 8 As shown, the automatic mushroom stick loading and unloading device 8 includes a protective column 81 vertically installed inside the cultivation room 2. The lower end of the protective column 81 is fixed to a rotary motor 88. The rotary motor 88 drives the entire device to rotate horizontally, so that the working range of its mechanical claw 87 can cover the mushroom stick loading / unloading area near the first cabinet door 21, realizing the storage and retrieval operation of mushroom sticks on multi-row mushroom stick placement trays. A vertical limiting groove 84 is formed on the side wall of the protective column 81. A vertical screw 82 is rotatably installed inside the protective column 81. A vertical drive motor 83 that drives the vertical screw 82 to rotate is fixed at the top of the protective column 81. The vertical screw 82 drives the precise lifting and lowering of the mechanical claw 87, achieving high positioning accuracy and facilitating the storage and retrieval of mushroom sticks at different heights on the mushroom stick placement tray 64. A ball bearing sleeve 85 is rotatably mounted on the vertical screw 82, and a lateral telescopic mechanism 86 is installed on the side wall of the ball bearing sleeve 85, which can drive the mechanical claw 87 to move laterally. One end of the lateral telescopic mechanism 86 is slidably installed in the vertical limiting groove 84. The vertical limiting groove 84 guides and prevents the lateral telescopic mechanism 86 from rotating, ensuring that it can only move in the vertical direction, thus improving the stability and accuracy of the picking and placing operation.

[0051] As another preferred embodiment of this utility model, such as Figure 9As shown, the lateral telescopic mechanism 86 includes a lateral support arm 861 mounted on the side wall of the ball sleeve 85. A lateral shaft 862 is rotatably mounted inside the lateral support arm 861. A lateral adjustment motor 864, which drives the lateral shaft 862 to rotate forward and backward, is mounted at one end of the lateral support arm 861. At least one section of a bidirectional screw 863 is formed on the lateral shaft 862. The bidirectional screw structure allows a single motor to drive the two mechanical claws 87 to move synchronously towards or away from each other, realizing clamping and releasing actions. The structure is compact, simple to control, and highly efficient. Two... The movable clamping plates 866 are movable in opposite directions. Each movable clamping plate 866 has a mechanical claw 87 formed at its lower end. The mechanical claw 87 can directly grasp the mushroom sticks to realize automated loading and unloading operations. The end of the mechanical claw 87 can be wrapped with soft material or adopt an adaptive structure to prevent damage to the mushroom sticks. The lower surface of the transverse support arm 861 has a transverse limiting groove 865 formed along the length direction to limit the movement of the movable clamping plates 866. The transverse limiting groove 865 ensures that the movable clamping plates 866 can only move in a straight line, preventing them from deflecting under the bidirectional screw drive and ensuring accurate positioning of the clamping center.

[0052] As another preferred embodiment of this utility model, such as Figure 3 As shown, the control room 3 is equipped with a solid-state battery 20 for providing power. The solid-state battery 20 is electrically connected to all power-consuming equipment through a backup automatic transfer system. The built-in solid-state battery can serve as a backup power source to provide emergency power to the environmental control system (such as temperature control and atmosphere control) when the external power supply is interrupted, maintain the system operation for ≥24 hours, prevent the bacteria from dying due to drastic environmental changes when the system stops, and improve the reliability of the equipment.

[0053] The working principle of this utility model is as follows: In use, the first cabinet door 21 is opened, and the inoculated mushroom logs are placed into the mushroom log placement tray 64 on the vertical cultivation rack 6 using the automatic mushroom log handling device 8. Then, the first cabinet door 21 is closed to seal the door and ensure the cultivation environment is isolated from the outside, creating conditions for the establishment of the internal micro-ecosystem. When the vertical cultivation rack 6 moves and passes the nutrient solution injection device 7, the first liquid pump 72 is controlled to inject nutrient solution into the corresponding mushroom log placement tray 64, ensuring that the mushroom logs can contact the nutrient solution. The combination of cyclical movement and fixed-point injection achieves timed and quantitative nutrient supply for batches of mushroom logs. This can be adjusted according to the movement of the vertical cultivation rack 6. The dynamic speed and preset growth model precisely control the nutrient solution supply and timing for each mushroom stick, avoiding waste and pollution. The carbon dioxide removal machine 10, aerator 11, atomizer 13, and hot and cold air fan 15 regulate the temperature, humidity, carbon dioxide and oxygen concentration in the cultivation room 2 to simulate the growth environment of fungi, keeping it in a state conducive to fungal growth and facilitating the growth and maturation of mycelium on the mushroom sticks. The integrated environmental control system can precisely maintain the optimal growth parameters (e.g., for matsutake: temperature 14-18°C, humidity 85-95%, CO2 concentration <1000ppm), significantly improving the yield and quality of fungi, shortening the production cycle, and reducing human intervention.
