Description

Technical Field

[0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to an edible fungus cultivation device. Background Art

[0002] Edible fungi refer to edible mushrooms (large fungi) with large fruiting bodies, commonly known as mushrooms. Edible fungi are rich in protein. For example, shiitake mushrooms have a high protein content and a relatively comprehensive amino acid composition, including many essential amino acids that the human body cannot synthesize on its own. They can be used as a source of high-quality plant protein.

[0003] In the cultivation of edible fungi, temperature, humidity and carbon dioxide concentration affect the cultivation quality. Currently, temperature, humidity and carbon dioxide concentration sensors are often used to accurately control the environment. Edible fungi have different requirements for temperature and humidity at different growth stages. When in the hyphae state, similar to the vegetative growth stage of plants, cell division and nutrient accumulation require higher temperatures to accelerate cell metabolism and material transport, promote hyphae growth, and the humidity requirement is lower at this time. When entering the fruiting body state, physiological activities turn to reproductive growth. Lower temperatures are conducive to primordium differentiation, can regulate cell signal transduction, enable cells to switch growth modes, and can also slow down respiration, reduce energy loss, and facilitate the construction of fruiting body morphology and material accumulation. If the temperature is too high, the fruiting body will grow weak due to excessive respiration and nutrient consumption. At the same time, as the hyphae develop into the fruiting body, the surface area increases, resulting in an increase in water evaporation area. Higher humidity is required to maintain turgor pressure and physiological functions, ensure cell division and elongation, and transport and distribution of nutrients, so that the fruiting body can grow strong. At present, in the cultivation process of edible fungi, the monitoring thresholds of temperature and humidity are set to fixed values, and the monitoring thresholds of temperature and humidity are manually adjusted when the edible fungi are cultivated to different degrees, such as an edible fungus cultivation device proposed in the patent announcement number CN113692919A. As a result, the cultivation quality of edible fungi is greatly affected. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Through the culture tanks, rotating support mechanisms, and material discharge confirmation mechanisms, the edible fungi culture substrates can be classified and quickly placed, which is convenient for taking and placing. In the subsequent humidification spraying process, the edible fungi can be evenly humidified and sprayed, and the number of edible fungi to be cultured can be determined, so that the initial ventilation power can be quickly determined. The more edible fungi are cultured, the more the initial ventilation power is set, because more edible fungi will consume more oxygen and produce more carbon dioxide during the growth process per unit time, and a larger ventilation volume is required to avoid the problem of excessive carbon dioxide concentration in the culture process affecting the culture quality of edible fungi.

[0020] 2. By setting up the air inlet pipe, exhaust pipe, dustproof net, exhaust fan and carbon dioxide concentration sensor, the carbon dioxide concentration can be monitored in real time based on the carbon dioxide concentration sensor during the cultivation of edible fungi, and the ventilation volume can be automatically adjusted to avoid the problem of excessive carbon dioxide concentration. The growth process of the edible fungi can be determined based on the ventilation volume. The larger the ventilation volume, the faster the carbon dioxide is generated, which means that the growth process of the edible fungi is later. Because with the growth of edible fungi, the demand for oxygen increases, which will accelerate the generation rate of carbon dioxide, and then reversely judge the growth process of the edible fungi, and perform more precise automatic control of the humidity environment and temperature environment of subsequent cultivation.

[0021] 3. Through the humidification spray mechanism, temperature control mechanism, temperature sensor, and humidity sensor, the temperature and humidity environment in the culture tank can be monitored in real time, and the temperature and humidity can be accurately and automatically adjusted. The set thresholds of temperature and humidity are automatically adjusted based on the working power of the exhaust fan. In the cultivation of edible fungi, the temperature and humidity need to be adjusted along with the cultivation process. In the initial growth stage, high temperature can accelerate cell metabolism and material transport, which is conducive to the growth of mycelium. Therefore, the temperature is relatively high in the early stage. When entering the fruiting body stage, physiological activities turn to reproductive growth. Low temperature can regulate cell signal transduction and help primordium differentiation. The temperature should be gradually lowered. As the edible fungi grow, their surface area increases and the water evaporation area increases. In order to maintain turgor pressure and physiological functions, the humidity needs to be increased to promote cell activity and nutrient transport. In addition, the speed of change of carbon dioxide concentration can be reversely judged according to the working power of the exhaust fan, so as to grasp the growth process and realize the automatic regulation of temperature and humidity thresholds, so that the cultivation environment of edible fungi is more accurate, without the need for manual observation and regulation, which not only improves the cultivation efficiency, but also avoids the problem that untimely manual adjustment will affect the quality of edible fungi cultivation.

[0038] The active drying mechanism 5 is arranged inside the air inlet cylinder 8 and is arranged in front of the temperature control mechanism 4. The active drying mechanism 5 includes a plurality of drying frames 51 equidistantly connected to the inner wall of the air inlet cylinder 8. Both ends of the drying frame 51 are arranged in arc structures. The drying frame 51 is connected to the air inlet cylinder 8 through a rotating shaft 52. The drying frame 51 is filled with hygroscopic silica gel 53. The opposite sides of the drying frame 51 are fixedly connected with ventilation mesh plates 54.

[0039] The deflection drive mechanism 7 includes a transmission gear 71 fixedly connected to the upper end of the rotating shaft 52, and a cover shell 72 covering multiple transmission gears 71 is fixedly installed on the upper end of the air inlet cylinder 8. A driving screw 73 is rotatably connected to one side of the inner wall of the cover shell 72, and a driving motor 74 for driving the driving screw 73 to rotate is fixedly installed on the outer wall of the cover shell 72. A movable plate 75 is threadedly sleeved on the rod wall of the driving screw 73, and a side wall of the movable plate 75 is fixedly connected to a transmission rack 76 meshing with multiple transmission gears 71.

[0040] The PLC controller 15 is fixedly mounted on the outer wall of the culture tank 1 and is electrically connected to the rotating support mechanism 2, the humidifying spray mechanism 3, the temperature control mechanism 4 and the active drying mechanism 5 respectively.

[0041] The operating principle of the present invention is now described as follows: the edible fungus culture substrate is placed on the support plate 25. The culture substrate has weight, so the support plate 25 will overcome the elastic force of the support spring 27 through the support rod 26 and move toward the extension plate 24, so that one of the support rods 26 presses on the confirmation switch 62. The confirmation switch 62 feeds back a signal to the PLC controller 15, indicating that there is a culture substrate for edible fungus culture. The more confirmation switch 62 feedback signals, the more edible fungi need to be cultured. The culture amount of edible fungi is determined based on the number of confirmation switch 62 feedback signals. The more confirmation switches 62 are pressed and triggered, the PLC controller 15 controls the exhaust fan 11 to work at a higher power initially. A ventilation channel is formed in the culture tank 1 through the cooperation of the exhaust cylinder 9 and the air inlet cylinder 8, and the carbon dioxide accumulated in the culture tank 1 is quickly discharged, because the more edible fungi consume more oxygen during culture, and then carbon dioxide will be produced faster. Increasing the ventilation volume can better avoid the problem of accelerated accumulation of carbon dioxide concentration in the initial process.

[0042] The temperature, humidity and carbon dioxide concentration of the environment in the culture tank 1 are monitored in real time by the temperature sensor 12, the humidity sensor 13 and the carbon dioxide concentration sensor 14. First, as the edible fungi continue to grow, the consumption of oxygen by the edible fungi will increase, and the speed of producing carbon dioxide will increase. At this time, the carbon dioxide concentration sensor 14 detects that the carbon dioxide concentration in the culture tank 1 increases. At this time, the PLC controller 15 controls the exhaust fan 11 to work at a higher power, increase the ventilation volume in the culture tank 1, and avoid the problem that the increase in the carbon dioxide concentration in the culture tank 1 affects the culture quality of the edible fungi;

[0043] When the temperature sensor 12 detects that the culture temperature in the culture tank 1 is lower than the set threshold, the PLC controller 15 controls the power supply device to supply a forward current to the semiconductor couple 41. The semiconductor couple 41 realizes cooling or heating based on the Peltier effect. The Peltier effect refers to when current passes through a loop composed of two different conductive materials (P-type and N-type semiconductors in the semiconductor couple 41), heat absorption or heat release will occur at the joint of the two materials. There are more "holes" (which can be regarded as positively charged carriers) in the P-type semiconductor, and more electrons (negatively charged carriers) in the N-type semiconductor. When direct current passes through this pair of PN junctions, the carriers move in a directed manner under the action of the electric field. When a forward current is supplied, the current flows from the N-type semiconductor to the P-type semiconductor, the electrons diffuse from the P-type semiconductor to the N-type semiconductor, and the holes diffuse from the N-type semiconductor to the P-type semiconductor. In this process, the carriers transition from a low energy state to a high energy state, which releases heat, thereby producing a heating effect. The incoming air is preheated by the semiconductor couple 41 and then enters the culture tank 1, thereby increasing the temperature in the culture tank 1 and ensuring that the temperature in the culture tank 1 reaches a preset threshold value. When the temperature sensor 12 detects that the culture temperature in the culture tank 1 is higher than the set threshold value, the PLC controller 15 controls the power supply device to supply a reverse current to the semiconductor couple 41, that is, when the current flows from the P-type semiconductor to the N-type semiconductor, at the joint, electrons diffuse from the N-type semiconductor to the P-type semiconductor, and holes diffuse from the P-type semiconductor to the N-type semiconductor. In this process, the carriers transition from a high energy state to a low energy state and need to absorb heat, thereby generating a cooling effect at this joint, thereby cooling the air entering the air inlet 8, effectively and quickly reducing the temperature in the culture tank 1, and when the temperature sensor 12 detects that the temperature in the culture tank 1 is significantly different from the preset threshold value, increasing the power supply current can increase the degree of heating or cooling, thereby accelerating the speed at which the temperature in the culture tank 1 reaches the set threshold value, thereby improving the control efficiency;

[0044] When the humidity sensor 13 detects that the humidity value in the culture tank 1 is lower than the set threshold, the PLC controller 15 controls the water supply pump 32 to work. The water supply pump 32 cooperates with the humidification pipe 31 to transport the external water source to the spray pipe 33, and sprays it through the atomizing nozzle 34. The atomizing nozzle 34 is a mechanical atomizing nozzle 34. After the water droplets are sprayed into mist, the humidity in the culture tank 1 is quickly increased. In the humidification process, the PLC controller 15 controls the rotation motor 22 to operate, and the rotation motor 22 drives the support shaft 21 to rotate, and the support shaft 21 drives The multiple culture substrates rotate so that the edible fungi can be evenly humidified and sprayed with water, thereby improving the humidification effect and ensuring the uniformity of the cultivation of the edible fungi. In addition, it is noted that when the difference between the humidity value monitored by the humidity sensor 13 and the set threshold value is smaller, the PLC controller 15 controls the working power of the water supply pump 32 to be smaller, so that the humidification amount per unit time is smaller, thereby avoiding the situation where the humidity value exceeds the set threshold value instantaneously due to excessive humidification, preventing repeated adjustments caused by inaccurate humidity control, and ensuring that the humidity is always stable and accurately maintained within the set range;

[0045] When the humidity sensor 13 detects that the humidity value in the culture tank 1 is higher than the set threshold value, the PLC controller 15 controls the drive motor 74 to operate, and the drive motor 74 drives the drive screw 73 to rotate. The threaded sleeve effect of the drive screw 73 and the movable plate 75 makes the movable plate 75 drive the transmission rack 76 to move a fixed distance, and the meshing effect of the transmission rack 76 and the transmission gear 71 drives the multiple rotating shafts 52 to drive the drying frame 51 to rotate 90 degrees. During the rotation of the drying frame 51, the drying frame 51 pushes the baffle plates 55 on both sides to both sides. The baffle plates 55 overcome the elastic force of the reset spring 59 through the sliding connection effect of the sliding seat 56 and the limiting slide bar 58, so that the side of the drying frame 51 corresponding to the ventilation mesh plate 54 is set to the windward direction, so that the air introduced into the air inlet 8 passes through the ventilation mesh plate 54 and the moisture-absorbing silica gel 53 filled in the drying frame 51 to dehumidify, and the humidity in the culture tank 1 is quickly reduced in combination with the ventilation effect.

[0046] As the growth of the edible fungi increases the rate of carbon dioxide generation in the culture tank 1, the PLC controller 15 will control the exhaust fan 11 to work at a higher power. The PLC controller 15 can reversely judge the culture process of the edible fungi based on the working power of the exhaust fan 11. As the working power of the exhaust fan 11 increases, the PLC controller 15 controls the monitoring threshold of the temperature sensor 12 to gradually decrease, and controls the monitoring threshold of the humidity sensor 13 to gradually increase. The specific adjustment data is that the growth temperature threshold of the edible fungi hyphae state is set to 20-25°C, and the growth temperature of the fruiting body growth stage is set to 8-12°C. The mycelium growth stage is mainly about cell division and accumulation of nutrients. This process is similar to the nutritional growth stage of plants. Higher temperatures can accelerate the rate of cell metabolism and material transportation, and promote the rapid growth and spread of hyphae. When entering the fruiting body formation and growth stage, the physiological activities of the edible fungi focus on reproductive growth. Lower temperatures are conducive to the differentiation of fruiting body primordia, because lower temperatures can regulate signal transduction in cells, so that cells switch from nutritional growth mode to reproductive growth mode.

[0047] At the same time, the PLC controller 15 controls the monitoring threshold of the humidity sensor 13 to gradually increase. The specific adjustment data is that the growth humidity threshold in the mycelium state of the edible fungus is set to 60-70%, and the growth temperature in the fruiting body growth stage is set to 80-90%. As the edible fungus grows, the surface area of ​​the edible fungus continues to increase, and the area of ​​water evaporation also increases accordingly. In order to maintain the turgor pressure and normal physiological function of the edible fungus, a higher humidity environment is required to reduce water loss;

[0048] The number of edible fungi cultivated is determined based on the number of confirmation switches 62 pressed and triggered, and the accuracy of the temperature and humidity monitoring threshold control is processed in combination with the working power of the exhaust fan 11. Specifically, when more confirmation switches 62 are pressed and triggered, the accumulation rate of carbon dioxide will increase exponentially in the same growth stage of edible fungi. At this time, the working power of the exhaust fan 11 controlled by the PLC controller 15 will also increase in the same manner. At this time, the PLC controller 15 controls the monitoring thresholds of the temperature sensor 12 and the humidity sensor 13 more accurately based on the number of confirmation switches 62 pressed and triggered and the power of the exhaust fan 11. When more confirmation switches 62 are pressed, at the same working power of the exhaust fan 11, the PLC controller 15 controls the monitoring thresholds of the temperature sensor 12 and the humidity sensor 13 to have a smaller adjustment range.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
