Technical Field
[0001] This utility model relates to the field of grassland mushroom culture medium fermentation technology, specifically a grassland mushroom culture medium fermentation temperature control device. Background Technology
[0002] The fermentation process of grassland mushroom substrate is extremely sensitive to temperature. In traditional fermentation processes, improper temperature control often leads to fermentation failure or poor fermentation quality. This is especially true in grassland areas, where there are large temperature differences between day and night and variable climate, making conventional temperature control devices difficult to adapt to.
[0003] Traditional heating and cooling methods, such as simple electric heating wires and natural ventilation, are either slow to heat up in grassland environments, making it difficult to quickly raise the temperature during low-temperature periods, or have poor heat dissipation effects, failing to effectively cope with heat accumulation during high-temperature periods. This results in existing temperature control devices having problems such as low heating and cooling efficiency and inability to adapt to harsh environments. Utility Model Content

In grassland environments, these methods either have slow heating speeds, making it difficult to quickly raise the temperature during low-temperature periods, or poor heat dissipation effects, failing to effectively cope with heat accumulation during high-temperature periods. As a result, existing temperature control devices suffer from problems such as low heating and heat dissipation efficiency and inability to adapt to harsh environments.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fermentation temperature control device for grassland mushroom culture medium, comprising a base, a fermentation chamber, and a three-way pipe. The fermentation chamber is provided with several compartments, and each compartment's outer surface is equipped with an air vent and a temperature and humidity sensor. The outer surface of the base is provided with a hot and cold air blower unit and a cold water tank. The output end of the hot and cold air blower unit is fixedly connected to an air duct. The outer surface of the air duct is provided with several No. 1 electrically controlled valves. The output end of the air duct passes through several No. 1 electrically controlled valves. The electrically controlled valve is fixedly connected to the air vent. Each of the compartments is fixedly equipped with an electric heating base. The output end of the electric heating base is provided with a culture tray. The contact surface between the electric heating base and the culture tray is provided with a serpentine cold water pipe. The output end of the cold water tank is fixedly connected to a cooling water pipe. The outer surface of the cooling water pipe is provided with several No. 2 electrically controlled valves. The cooling water pipe is fixedly connected to the serpentine cold water pipe through the No. 2 electrically controlled valves. The outer surface of the fermentation chamber is provided with several motorized louvers. The motorized louvers are fixedly connected to the compartments.
[0006] Preferably, a power supply box, a nutrient solution tank, and a water supply tank are fixedly installed on the outer surface of the base. A plurality of solar panels are installed on the outer surface of the fermentation chamber, and each of the solar panels is electrically connected to the power supply box. Atomizing nozzles are installed in each of the compartments. The nutrient solution tank and the water supply tank are connected via a three-way pipe, and control valves are installed at the connections between the three-way pipe and the nutrient solution tank and the water supply tank. A pipe is fixedly connected to the output end of the three-way pipe, and a plurality of No. 3 electrically controlled valves are installed on the outer surface of the pipe. The output end of the pipe is fixedly connected to the atomizing nozzles via the plurality of No. 3 electrically controlled valves.
[0007] Preferably, the interior of the cold water tank, the water supply tank, and the nutrient solution tank is equipped with a pump body, and the outer surface of the base is equipped with a controller.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This grassland mushroom culture substrate fermentation temperature control device uses a temperature and humidity sensor to detect when the temperature exceeds the suitable value for mushroom fermentation. When the temperature exceeds the suitable value, the device transmits an electrical signal to the controller, triggering coordinated actions of the hot and cold air units and electric louvers. When the temperature is too high, the hot and cold air units deliver cold air, while the electric louvers automatically adjust their opening to assist in ventilation and heat dissipation. In the early stage of fermentation, the temperature needs to be increased, and the electric heating base is powered on to generate heat. The heat is transferred to the culture tray through the contact surface. In the later stage, when the temperature is too high, the cooling water from the cold water tank enters the serpentine cold water pipe, using the specific heat capacity of water to absorb heat. This achieves the effect of reducing the low heating and heat dissipation efficiency and inability to adapt to harsh environments that are inherent to temperature control devices.
[0011] 2. This grassland mushroom culture substrate fermentation temperature control device utilizes solar panels to efficiently generate electricity through the photoelectric effect during periods of strong sunlight on the grassland. Excess electricity is stored in the battery of the power supply unit. When there is insufficient sunlight, such as at night or on cloudy days, the power supply unit supplies power to the key components of the device. When the temperature and humidity sensor detects insufficient humidity in the compartment, the No. 3 electric control valve opens according to the control command, and water from the water supply tank is delivered to the atomizing nozzle through pipes and T-junctions to spray out fine mist and increase humidity. If nutrient solution needs to be added, the nutrient solution in the nutrient solution tank is regulated by the control valve and then sprayed out through the T-junction, pipes, and the No. 3 electric control valve to the atomizing nozzle, thereby achieving the effect of saving resources and achieving precise replenishment of humidity and nutrients.

[0014] 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.
[0015] Example 1: Please refer to Figures 1-4. A temperature control device for fermentation of grassland mushroom culture medium includes a base 1, a fermentation chamber 2, and a three-way pipe 19. The fermentation chamber 2 is provided with several compartments 12, and each compartment 12 is provided with an air outlet 14 and a temperature and humidity sensor 13 on its outer surface. The outer surface of the base 1 is provided with a hot and cold air blower unit 6 and a cold water tank 9. The output end of the hot and cold air blower unit 6 is fixedly connected to an air duct 7. The outer surface of the air duct 7 is provided with several No. 1 electrically controlled valves 8, and the output end of the air duct 7 is fixedly connected to the air outlets 14 through the several No. 1 electrically controlled valves 8. Each of the several compartments 12 is equipped with an electric heating base 15. The output end of the electric heating base 15 is equipped with a culture tray 16. The contact surface between the electric heating base 15 and the culture tray 16 is equipped with a serpentine cold water pipe. The output end of the cold water tank 9 is fixedly connected to a cooling water pipe 10. The outer surface of the cooling water pipe 10 is equipped with several No. 2 electric control valves 11. The cooling water pipe 10 is fixedly connected to the serpentine cold water pipe through the No. 2 electric control valves 11. The outer surface of the fermentation room 2 is equipped with several electric louvers 3. The electric louvers 3 are fixedly connected to the compartment 12.
[0016] Specifically, when the temperature and humidity sensor 13 detects that the temperature is higher than the suitable value for mushroom fermentation, it transmits an electrical signal to the controller, triggering coordinated actions of the hot and cold air unit 6, electric louvers 3, etc. When the temperature is too high, the control system receives the sensor signal and instructs the first electric control valve 8 to open the corresponding air outlet 14. The hot and cold air unit 6 delivers cold air, and at the same time, the electric louvers 3 automatically adjusts the opening to assist ventilation and heat dissipation. In the early stage of fermentation, the temperature needs to be increased, so the electric heating base 15 is powered on and heats up. The heat is transferred to the cultivation tray 16 through the contact surface. In the later stage, when the temperature is too high, the second electric control valve 11 opens, and the cooling water from the cold water tank 9 enters the serpentine cold water pipe. The specific heat capacity of the water is used to absorb heat, thereby reducing the effect of low heating and heat dissipation efficiency and inability to adapt to harsh environments in the temperature control device.
[0017] In the embodiment: the culture tray 16 is made of a double-layer heat insulation structure, and several heating bases 15 all use graphene heating film as heating element.
[0018] Specifically, the culture tray 16 is made of a double-layer insulation structure. The inner layer is made of ceramic fiber material with moderate thermal conductivity and good insulation, and the outer layer is made of polyurethane material with excellent heat insulation performance. When the electric heating base 15 provides heat or the serpentine cold water pipe provides cooling, the double-layer structure can effectively prevent the heat of the culture medium in the culture tray 16 from being lost quickly or from absorbing too much external heat, so that the temperature fluctuation in the compartment 12 is smaller. For example, in grassland environments with large diurnal temperature variations, the outside temperature drops sharply at night. The double-layered insulated culture tray 16 can reduce the impact of low external temperatures on the temperature of the culture medium inside the tray, ensuring stable fermentation temperature and improving the fermentation quality of the mushroom culture medium. At the same time, several electric heating bases 15 all use graphene heating films as heating elements. Graphene has excellent thermal conductivity, which can quickly convert electrical energy into heat energy and heat up evenly. Compared with traditional heating elements such as resistance wires, how can the graphene heating film make the surface temperature of the electric heating base 15 more evenly transferred to the culture tray 16, avoiding local fermentation abnormalities of the culture medium due to uneven heating? With a large area of the culture tray 16, the graphene heating film can achieve overall heating in a short time, and the temperature difference between different areas is minimal, ensuring the consistency of the culture medium fermentation environment.
[0019] Working principle: The fermentation chamber 2 is equipped with several compartments 12, each with an air vent 14 and a temperature and humidity sensor 13 on its outer surface. The base 1 has a hot and cold air unit 6 and a cold water tank 9 on its outer surface. The output of the hot and cold air unit 6 is fixedly connected to a duct 7, and the duct 7 has several first-order electrically controlled valves 8 on its outer surface. The output of the duct 7 is fixedly connected to the air vents 14 via these valves. Each compartment 12 has a fixedly installed electric heating base 15, with a cultivation tray 16 at its output. A serpentine cold water pipe is installed at the contact surface between the electric heating base 15 and the cultivation tray 16. The cold water tank 9 has a fixedly connected cooling water pipe 10 at its output. The cooling water pipe 10 has several second-order electrically controlled valves 11 on its outer surface, and these valves are fixedly connected to the serpentine cold water pipe via the second-order valves 11. The fermentation chamber 2 has several electrically controlled valves... The louver 3 and the electric louver 3 are fixedly connected to the compartment 12. When the temperature and humidity sensor 13 detects that the temperature is higher than the suitable value for mushroom fermentation, it transmits an electrical signal to the controller, triggering the coordinated action of the hot and cold air unit 6, the electric louver 3, etc. When the temperature is too high, the control system receives the sensor signal and instructs the first electric control valve 8 to open the corresponding air outlet 14. The hot and cold air unit 6 delivers cold air, and at the same time, the electric louver 3 automatically adjusts its opening to assist in ventilation and heat dissipation. In the early stage of fermentation, the temperature needs to be increased. The electric heating base 15 is powered on and heats up. The heat is transferred to the culture tray 16 through the contact surface. In the later stage, when the temperature is too high, the second electric control valve 11 opens, and the cooling water in the cold water tank 9 enters the serpentine cold water pipe. The specific heat capacity of the water is used to absorb the heat. Compared with related technologies, the grassland mushroom culture substrate fermentation temperature control device provided by this utility model has the following beneficial effects: thereby reducing the low heating and heat dissipation efficiency and inability to adapt to harsh environments of the temperature control device.
[0020] Example 2: Please refer to Figures 1-4. The outer surface of the base 1 is fixedly installed with a power supply box 5, a nutrient solution tank 18 and a water supply tank 17. The outer surface of the fermentation chamber 2 is provided with several solar power generation panels 4, which are electrically connected to the power supply box. Several compartments 12 are provided with atomizing nozzles 21. The nutrient solution tank 18 and the water supply tank 17 are connected by a three-way pipe 19, and a control valve is provided at the connection between the three-way pipe 19 and the nutrient solution tank 18 and the water supply tank 17. The output end of the three-way pipe 19 is fixedly connected to a pipe, and several No. 3 electric control valves 20 are provided on the outer surface of the pipe. The output end of the pipe is fixedly connected to the atomizing nozzles 21 through several No. 3 electric control valves 20.
[0021] Specifically, during periods of intense sunlight on the grassland, the solar panels generate electricity efficiently through the photoelectric effect, and excess energy is stored in the battery of the power supply unit 5. When there is insufficient sunlight, such as at night or on cloudy days, the power supply unit 5 supplies power to the key components of the device. When the temperature and humidity sensor 13 detects insufficient humidity in the compartment 12, the third electric control valve 20 opens according to the control command, and the water in the water supply tank 17 is transported to the atomizing nozzle 21 through pipes, tee pipes 19, etc., to spray out fine mist to increase humidity. If nutrient solution needs to be replenished, the nutrient solution in the nutrient solution tank 18 is regulated by the control valve and sprayed out through the tee pipe 19, pipes, and the third electric control valve 20 to the atomizing nozzle 21, thereby achieving the effect of saving resources and achieving precise replenishment of humidity and nutrients.
[0022] In the embodiment: pump bodies are installed inside the cold water tank 9, the water supply tank 17 and the nutrient solution tank 18, and a controller is installed on the outer surface of the base 1. The controller is electrically connected to the hot and cold air unit 6, the pump body of the cold water tank 9, the pump body of the water supply tank 17, the pump body of the nutrient solution tank 18, the power supply box 5, the electric louver 3, the electric heating base 15 and the temperature and humidity sensor 13.
[0023] Specifically, pumps are installed inside the cold water tank 9, water supply tank 17, and nutrient solution tank 18. A controller is installed on the outer surface of the base 1. The controller is electrically connected to the hot and cold air unit 6, the pumps in the cold water tank 9, water supply tank 17, and nutrient solution tank 18, the continuous power supply unit 5, the electric louvers 3, the electric heating base 15, and the temperature and humidity sensor 13. The controller is an existing structure, and the control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail. This facilitates centralized control of the relevant structures. Combined with modern Internet of Things technology, remote monitoring and management can be achieved by adding communication modules such as 4G / 5G and WiFi to the controller. Growers or managers can view data such as temperature and humidity and equipment operating status in the fermentation room 2 anytime and anywhere through a mobile APP or computer, and remotely control the equipment to start and stop and adjust parameters. If an abnormal temperature is detected in a compartment 12 while the user is away, the hot and cold air units 6 can be remotely activated to adjust the temperature. Furthermore, historical data records can be used to analyze fermentation process trends, optimize production management strategies, reduce management costs, and improve management efficiency.
[0024] In this embodiment: both the water supply tank 17 and the nutrient solution tank 18 are equipped with electric heating rods, which are electrically connected to the power supply unit 5.
[0025] Specifically, electric heating rods are installed inside both the water supply tank 17 and the nutrient solution tank 18. The electric heating rods are electrically connected to the power supply unit 5. The electric heating rods heat the liquid in the tank to a suitable temperature. After being sprayed out through the atomizing nozzle 21, the humidity regulation effect is ensured without impacting the temperature of the fermentation room 2. In conjunction with the electric heating base 15, the hot and cold air unit 6, etc., a precise balance of temperature and humidity is achieved, creating a more ideal microenvironment for mushroom growth.
[0026] Working principle: A continuous power supply box 5, a nutrient solution tank 18, and a water supply tank 17 are fixedly installed on the outer surface of the base 1. Several solar panels 4 are installed on the outer surface of the fermentation chamber 2, and all of the solar panels 4 are electrically connected to the continuous power supply box. Several compartments 12 are equipped with atomizing nozzles 21. The nutrient solution tank 18 and the water supply tank 17 are connected by a three-way pipe 19, and control valves are installed at the connection points of the three-way pipe 19 with the nutrient solution tank 18 and the water supply tank 17. The output end of the three-way pipe 19 is fixedly connected to a pipe, and several No. 3 electric control valves 20 are installed on the outer surface of the pipe, and the output end of the pipe is connected to... Several No. 3 electric control valves 20 are fixedly connected to the atomizing nozzles 21. During periods of strong sunlight on the grassland, the solar panels generate electricity efficiently through the photoelectric effect. Excess electricity is stored in the battery of the power supply box 5. When there is insufficient sunlight, such as at night or on cloudy days, the power supply box 5 supplies power to the key components of the device. Compared with traditional fermentation devices that rely entirely on mains electricity, the electricity cost savings over long-term operation due to the application of solar panels 4 and power supply box 5 can be calculated. Combining data such as the length of sunshine in the grassland area and the efficiency of solar power generation, it can be shown that the annual energy expenditure can be reduced, demonstrating the significant advantages of the device in energy saving and cost reduction, attracting agricultural production. The main production method aligns with the trend of green agriculture. When the temperature and humidity sensor 13 detects insufficient humidity in compartment 12, the No. 3 electric control valve 20 opens according to the control command. Water from the water supply tank 17 is transported to the atomizing nozzle 21 through pipes and T-connector 19, spraying out a fine mist to increase humidity. If nutrient solution needs to be added, the nutrient solution from the nutrient solution tank 18 is regulated by the control valve, flowing through the T-connector 19, pipes, and the No. 3 electric control valve 20 to the atomizing nozzle 21. Because each compartment 12 has an independent atomizing nozzle 21 and a No. 3 electric control valve 20, humidity can be precisely controlled according to the fermentation stage of the culture medium in different compartments 12 and the differences in mushroom varieties. Nutrient solution supply, for example, in some compartments 12 for cultivating grassland white mushrooms, high humidity and specific nutrient solution components are required during the mycelial growth stage. The amount of water sprayed by the atomizing nozzle 21 and the amount of nutrient solution can be precisely controlled by the No. 3 electric control valve 20 of the corresponding compartment 12. For matsutake mushrooms cultivated in adjacent compartments 12, different settings are made according to their growth needs, so as to realize the parallel fermentation of multiple varieties and batches with precise environmental adaptation, which improves the application flexibility and practicality of the device. Compared with related technologies, the grassland mushroom culture substrate fermentation temperature control device provided by this utility model has the following beneficial effects: thereby achieving the effect of saving resources and achieving precise replenishment of humidity and nutrients.
