Description

Technical Field

[0001] This utility model relates to the field of matsutake mycelium culture technology, specifically a special device for the propagation and culture of matsutake mycelium. Background Technology

[0002] Matsutake mycelium culture involves artificially simulating the natural growth environment of matsutake mushrooms. Under sterile conditions, the mycelium is inoculated into a specialized culture medium (such as modified PDA medium containing pine sawdust extract and maltose) and placed in a culture device with constant temperature (18-22℃), high humidity (85-90% RH), darkness, and a suitable CO2 concentration (1000-1500 ppm). Laminar flow purification technology is used to avoid contamination by other microorganisms, and growth conditions are optimized through dynamic sterilization and real-time monitoring systems. The mycelium typically colonizes the culture container within 12-15 days. During this period, the mycelial morphology and contamination status need to be observed regularly to obtain pure, highly active mycelium for subsequent strain propagation, extraction of metabolites, or artificial cultivation.

[0003] The propagation and cultivation of matsutake mycelium requires extremely strict environmental conditions, especially air cleanliness, which directly affects the healthy growth of the mycelium. During the cultivation process, metabolic waste gases are continuously generated inside the cultivation device, and microorganisms, dust, and volatile organic compounds from the outside air may also enter the cultivation environment. If the device lacks gas purification capabilities, it will first lead to an imbalance in the CO2 concentration in the cultivation environment; excessively high concentrations will inhibit mycelial respiration, while excessively low concentrations will affect mycelial metabolic efficiency. Secondly, contaminants from the outside air may enter the cultivation container with the airflow, competing with the matsutake mycelium for nutrients and even causing contamination, resulting in slow mycelial growth, yellowing, or death. In addition, if volatile organic compounds are not filtered, they may interfere with mycelial enzyme activity, affecting the synthesis of secondary metabolites. Long-term accumulation of waste gases can also change the pH value of the culture medium, further inhibiting mycelial propagation efficiency. Ultimately, gas pollution will significantly reduce the biomass and quality of the mycelium, increase the cultivation failure rate, and even affect the stability of subsequent artificial cultivation or industrial production.

[0004] During the propagation and cultivation of matsutake mycelium, the gas purification system needs to continuously treat metabolic waste gases (such as CO2 and ethylene) generated inside the cultivation device, as well as any potentially proliferating airborne bacteria. Over long-term operation, the air-facing side of the filter screen will continuously intercept microorganisms, mycelial fragments, and volatile organic particles from the culture medium in these waste gases. Initially, these substances form a slight adhesion on the filter screen surface, resulting only in a slight decrease in gas flow rate, and the system can still maintain basic purification efficiency. However, over time, the adhesion gradually thickens, forming a dense biofilm layer, leading to a significant reduction in filter porosity.

[0005] To address the aforementioned issues, we have made improvements and proposed a special propagation and cultivation device for matsutake mycelium. Utility Model Content

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.

[0022] Please see Figure 1-4 A special propagation and cultivation device for matsutake mycelium includes a base plate 1, an incubator 2 fixedly connected to the top of the base plate 1, a filter box 3 fixedly connected to the right side of the incubator 2, a fixing box 4 fixedly connected to the back side of the filter box 3, a first retaining seat 6 fixedly connected to the top of the front and back sides of the inner cavity of the filter box 3, a dust filter screen 7 being engaged in the inner cavity of the first retaining seat 6, and collection grooves 8 being provided on both the front and back sides of the dust filter screen 7. A crankshaft 14 is movably connected to the inner cavity of the fixing box 4 via bearings, and a movable sleeve 15 is movably connected to the surface of the crankshaft 14. A connecting rod 16 is movably connected to the side via a pivot. A mounting base 17 is movably connected to the front side of the connecting rod 16 via a pivot. A scraper 18 is snapped onto the front side of the mounting base 17. The bottom of the scraper 18 contacts the top of the dust filter screen 7. A servo motor 13 for driving the crankshaft 14 to rotate is fixedly connected to the right side of the fixed box 4. The output end of the servo motor 13 is fixedly connected to the front end of the crankshaft 14. Guide grooves 20 are provided on the back side of the filter box 3 and the front side of the fixed box 4. The front side of the connecting rod 16 passes through the inner cavity of the guide groove 20 and extends into the inner cavity of the filter box 3.

[0023] Through the above technical solution, the output end of the servo motor 13 drives the crankshaft 14 to rotate. During the rotation, the crankshaft 14 uses the crank mechanism principle to drive the scraper 18 to move back and forth through the transmission of the movable sleeve 15 and the connecting rod 16. The scraper 18 cleans the top of the dust filter screen 7 and pushes the accumulated material into the inner cavity of the collection tank 8 for collection, avoiding the dust filter screen 7 from being blocked and thus preventing the filtration from failing. The sliding groove 25 and the slider 19 can effectively improve the stability of the scraper 18 during the back and forth movement.

[0024] Specifically, a chute 25 is provided on the left side of the filter box 3, and a slider 19 is fixedly connected to the back side of the scraper 18. The back side of the slider 19 is slidably connected to the inner cavity of the chute 25. A second bracket 9 is fixedly connected to both the front and back sides of the inner wall of the filter box 3. There are two sets of second brackets 9, and HEPA filters 10 are clamped into the inner cavities of both sets of second brackets 9. A connecting pipe 5 is connected to the top of the filter box 3. The left end of the connecting pipe 5 is connected to the top right side of the incubator 2. A drainage fan 11 is fixedly connected to the bottom of the filter box 3. A horn pipe 12 is connected to the input end of the drainage fan 11. The output end of the drainage fan 11 extends to the right side of the filter box 3. Slide rails 22 are fixedly connected to both the left and right sides of the inner wall of the incubator 2. A tray 23 is slidably connected to the inner cavity of the slide rail 22. A culture tray 24 is fixedly connected to the top of the tray 23. A growth lamp 21 is fixedly installed in the inner cavity of the incubator 2 and above the culture tray 24.

[0025] Through the above technical solution, by setting the HEPA filter 10, the purification effect of the gas can be further improved. By setting the first card holder 6 and the second card holder 9, the dust filter 7 and the collection tank 8 can be disassembled for deep cleaning or replacement. The gas in the incubator 2 is drawn into the filter box 3 through the connecting pipe 5 by the suction generated by the duct fan 11. After passing through the dust filter 7 and the second card holder 9, the gas is filtered multiple times to avoid direct discharge of gas and pollution to the external environment.

[0026] During use, the suction force generated by the duct fan 11 draws the gas from the inner cavity of the incubator 2 into the inner cavity of the filter box 3 through the connecting pipe 5. The gas then passes through the dust filter 7 and the second card holder 9 for multiple filtrations, preventing direct exhaust and pollution of the external environment. During long-term filtration, the output of the servo motor 13 drives the crankshaft 14 to rotate. During rotation, the crankshaft 14 uses the crank mechanism principle to drive the scraper 18 to move back and forth through the movable sleeve 15 and the connecting rod 16. The scraper 18 cleans the top of the dust filter 7 and pushes the accumulated material into the inner cavity of the collection tank 8 for collection, preventing the filter holes of the dust filter 7 from becoming clogged and preventing filtration from failing (the above is the working process of the entire device; the contents not described in detail in this specification are existing technologies known to those skilled in the art).
