Description

Technical Field

[0001] The invention relates to an edible fungus cultivation device, in particular to an integrated fungus room environment machine. Background Art

[0002] Edible fungi contain amino acids, proteins, carbohydrates, lipids, vitamins and minerals, and other nutrients required by the human body. They also have good effects of inhibiting tumors, regulating immunity and lowering cholesterol. With the gradual improvement of people's living standards in my country, the domestic consumption of edible fungi is increasing, and most urban residents have become the main consumers of edible fungi. Calculated based on the consumption of 100g of edible fungi per person per day in a city with a population of 3 million, a city can consume 300,000 kilograms of edible fungi per day, and the annual consumption can reach 1.1 million tons. There are more than 50 cities in my country with a population of more than 3 million. The consumption of these cities alone is more than five times the current production of edible fungi. It is expected that in the next 20 years, the consumption of edible fungi in my country will continue to grow rapidly, and the development prospects of the edible fungi market are very broad. This requires the provision of mushroom house environment machines specifically for the cultivation of edible fungi, combined with large-scale and factory-based planting to meet market demand.

[0003] The intensive and industrialized production of edible fungi is a relatively complex overall system. It is not possible to detect and control a single parameter, but the entire production environment of edible fungi must be controlled comprehensively, simultaneously, and consistently. Through a series of practical projects, it is found that the factors that have the greatest impact on the growth rate, quality, and yield of edible fungi include four aspects: temperature, humidity, CO2 concentration, and light intensity. The requirements for these four factors vary depending on the type of edible fungi and the different growth stages they are in. Therefore, a technology that can perform overall control based on the specific type of edible fungi and the specific growth stage of edible fungi is extremely important.

[0004] Therefore, the Chinese patent document with the publication number CN107622361B discloses a mathematical modeling and control method for the edible fungus greenhouse environment, and sets a data acquisition mechanism, a data processing mechanism and an action execution mechanism, and establishes an objective function model and a real-time function model based on the four factors of temperature, humidity, carbon dioxide concentration and illumination in the data processing mechanism. According to the deviation factor and deviation degree of the objective function model and the real-time function model, the corresponding control mode of the action execution mechanism is enabled to complete the real-time regulation of the edible fungus greenhouse environment. Through the collected historical edible fungus room production environment data, the influence of temperature, humidity, CO2 concentration and light intensity on the yield and quality of edible fungi is compared and studied, and a control model is innovated to adjust the temperature, humidity, CO2 and light of the fungus room as a whole, so that the edible fungi are always in the best growth environment, and the model and control correction can be controlled according to actual needs. Provide multi-directional guidance for the environmental regulation of edible fungus greenhouses.

[0005] However, technicians in this field have found during use that although the control method (taking into account the four factors of temperature, humidity, CO2 concentration and light intensity) can achieve a relatively high yield and quality of edible fungi when applied to actual production, the cost is high and the equipment is large, that is, it occupies a large area, which makes it impossible to achieve a high cost-effectiveness in the production process of edible fungi.

[0006] The Chinese patent document with publication number CN102726212B discloses a mushroom house environment machine, which senses the real-time temperature, humidity and carbon dioxide concentration in the mushroom house through temperature sensors, humidity sensors, carbon dioxide concentration sensors and the like arranged in the mushroom house, and then analyzes and processes through a programmable controller, and automatically controls a compressor, a centrifugal fan, an electric heating tube group, a humidifier, an electric fresh air device and a ventilation fan, etc., to realize automatic regulation and control of the temperature, humidity and carbon dioxide concentration in the mushroom house environment, to ensure constant temperature and humidity in the mushroom house, and to automatically turn on the electric fresh air device and the ventilation fan when the carbon dioxide concentration in the mushroom house increases, to control the carbon dioxide concentration within a suitable range, so that the mushroom house has a good growth environment for mushrooms; the invention only considers the influencing factors of temperature, humidity and CO2 concentration, appropriately reduces the cost and the equipment footprint, improves the cost performance of producing mushrooms, is easy to operate, has a good control effect, is conducive to large-scale and factory-based cultivation and production of edible mushrooms, and is worthy of promotion and application.

[0007] But it still has the following shortcomings:

[0008] 1) Among the four factors of temperature, humidity, CO2 concentration and light intensity, temperature and CO2 concentration have the greatest impact on the yield and quality of edible fungi. Therefore, the cost performance of mushroom house environment machine can be further improved;

[0009] 2) The existing mushroom house environment machine is still large in size and occupies a large area, which affects the cultivation area of ​​edible fungi;

[0010] 3) When the indoor CO2 concentration of the existing mushroom house environment machine is too high, it is difficult to effectively and quickly reduce the indoor CO2 concentration by simply introducing outdoor fresh air. Summary of the invention

[0040] like Figure 1-5 The mushroom room environment integrated machine shown in the figure comprises an edible mushroom room, a frame 1, a blower 20 and a control cabinet 21. The control cabinet 21 and the blower 20 are mounted on the frame 1 and are respectively located on two opposite sides of the frame 1. The edible mushroom room is also provided with a supply air duct, a return air duct and a fresh air duct connected to the frame 1. The improvement made is that:

[0041] The edible mushroom house is also provided with at least one temperature sensor and at least one CO2 concentration sensor; the frame 1 is provided with a temperature control device and a CO2 concentration control device, the control cabinet 21 is provided with a temperature control unit and a CO2 concentration control unit, the temperature control unit controls the temperature in the edible mushroom house through the temperature control device and the temperature sensor, and the CO2 concentration control unit controls the CO2 concentration in the edible mushroom house through the CO2 concentration control device and the CO2 concentration sensor;

[0042] The CO2 concentration control device includes a switching device and a finned evaporator 22. A middle partition 10 is also provided in the frame 1. The middle partition 10 and the finned evaporator 22 are distributed in parallel, and the inside of the frame 1 is divided into a first chamber 11, a second chamber 12 and a third chamber 13 in sequence. The first chamber 11 and the second chamber 12 are respectively located on both sides of the middle partition 10, and the second chamber 12 and the third chamber 13 are respectively located on both sides of the finned evaporator 22. The control cabinet 21 is located in the first chamber 11, and the air blower 20 is located on the outside of the third chamber 13 and is connected to the air supply pipe. At least one fresh air inlet 14 is provided on the first chamber 11, and at least two return air inlets are provided on the second chamber 12. A vent 30 is provided on the middle partition 10; the switching device is used to open the vent 30 and close a return air inlet at the same time, or to open a return air inlet and close the vent 30 at the same time.

[0043] In this way, the real-time temperature and carbon dioxide concentration in the mushroom room are sensed by the temperature sensor and carbon dioxide concentration sensor arranged in the mushroom room, and then analyzed and processed by the temperature control unit and the CO2 concentration control unit, and the compressor 24, the air blower 20, the switching device, etc. are automatically controlled to realize automatic regulation and control of the temperature and carbon dioxide concentration of the environment in the mushroom room, and ensure the constant temperature of the mushroom room. When the carbon dioxide concentration in the mushroom room increases, the switching device is automatically turned on to control the carbon dioxide concentration within a suitable range, so that the mushroom room has a good growth environment for mushrooms. The structure of the present invention is reasonable and compact, the cost is reasonable, the operation is simple, the control effect is good, it is conducive to large-scale and factory-based planting and production of edible mushrooms, and it is worth promoting and applying.

[0044] In this embodiment, since the only equipment that the rack 1 needs to carry as a whole is a temperature control device and a CO2 concentration control device, the floor space of the rack 1 is greatly reduced, and since the load is reduced, the rack 1 as a whole can be installed on the top of the mushroom room, and thus no longer occupies the cultivation area of ​​edible fungi; at the same time, since the air temperature delivered by the blower 20 is basically lower than the indoor air temperature, when the blower 20 is located at the top of the mushroom room, the delivered air can be evenly transmitted to every corner of the mushroom room, so that the temperature and CO2 concentration in the mushroom room are uniform, which is conducive to the balanced growth of edible fungi in batches and on a large scale.

[0045] It is worth noting that the rack 1 can be installed on the top of the mushroom house by hoisting, embedding, or building support beams or other methods, which will not be described in detail here.

[0046] In this embodiment, a first return air inlet 15 and a second return air inlet 16 are provided on the second chamber 12, wherein the first return air inlet 15 is located at the bottom or top of the second chamber 12, and the second return air inlet 16 of the rack 1 is located at the side wall of the second chamber 12, and the switching device is used to open the vent 30 and close the first return air inlet 15 at the same time, or to open the first return air inlet 15 and close the vent 30 at the same time; wherein, when the rack 1 is located at the top of the mushroom room, the first return air inlet 15 is located at the bottom of the second chamber 12, and when the rack 1 is located on the floor of the mushroom room, the first return air inlet 15 is located at the top of the second chamber 12.

[0047] In this embodiment, the switching device includes a sealing plate 17, a damper actuator 23 and a connecting device. The sealing plate 17 is rotatably mounted on the middle partition 10 or the frame 1. The damper actuator 23 enables the sealing plate 17 to have a first stop position and a second stop position through the connecting device. When the sealing plate 17 is located at the first stop position, the sealing plate 17 seals the first return air inlet 15. When the sealing plate 17 is located at the second stop position, the sealing plate 17 seals the vent 30. This arrangement is because the damper actuator 23 has only two states, fully open and fully closed, so that the sealing plate 17 can have a first stop position and a second stop position.

[0048] In this embodiment, the connecting device includes a first connecting shaft 18 and a second connecting shaft 19, one end of the first connecting shaft 18 is fixedly connected to the air valve actuator 23 and the other end is hinged to one end of the second connecting shaft 19, and the other end of the second connecting shaft 19 is rotatably mounted on the sealing plate 17; such an arrangement has a simple structure and minimizes the obstruction to fresh air.

[0049] In this embodiment, the temperature control device includes a compressor 24, a condenser 25, a drying filter 26 and an expansion valve 27, and the compressor 24, the condenser 25, the drying filter 26, the expansion valve 27, the finned evaporator 22 and the blower 20 are connected in a refrigerant pipeline circulation, wherein the compressor 24 and the condenser 25 are located in the first chamber 11, and the drying filter 26 and the expansion valve 27 are located in the second chamber 12.

[0050] In this embodiment, the refrigerant pipeline includes an intake pipe, an exhaust pipe, a high-pressure liquid pipe and a low-pressure liquid pipe. The compressor 24 is connected to the condenser 25 through an exhaust pipe; the shell and tube condenser 25, the drying filter 26 and the expansion valve 27 are connected through a high-pressure liquid pipe; the expansion valve 27 is connected to the finned evaporator 22 through a low-pressure liquid pipe; the finned evaporator 22 is connected to the compressor 24 through an intake pipe.

[0051] In this embodiment, the CO2 concentration control device also includes at least one fresh air panel, which is provided with a plurality of staggered holes to form a fresh air inlet 14; further preferably, there are two fresh air panels, which are respectively located on the two side walls of the first chamber 11.

[0052] In this embodiment, the CO 2 concentration control device further includes at least one air filter, which is located in the first chamber 11 and at the fresh air inlet 14 .

[0053] The working process of this embodiment is as follows:

[0054] Cooling process: When the temperature sensor installed in the edible mushroom house detects that the temperature is too high, the temperature sensor transmits a signal to the temperature control unit in the control cabinet 21, and then the refrigerant is compressed by the compressor 24, and changes from low-temperature and low-pressure gas to high-temperature and high-pressure gas. The high-temperature and high-pressure gas is connected to the condenser 25 through the exhaust pipe, and exchanges heat with the cooling water therein and is cooled to become a normal-temperature and high-pressure liquid; the normal-temperature and high-pressure liquid enters the expansion valve 27 through the high-pressure liquid pipe for throttling, so that the normal-temperature and high-pressure liquid is a low-temperature and low-pressure gas-liquid two-phase substance; finally, the low-temperature and low-pressure gas-liquid two-phase refrigerant enters the finned evaporator 22 through the low-pressure liquid pipe, and evaporates therein, and the evaporation of the refrigerant needs to absorb heat, so that the air entering the second chamber 12 through the first return air port and the second return air port is cooled, and the low-temperature air is transported to the air supply pipe through the blower 20 and enters the edible mushroom house, thereby cooling the entire mushroom house; the refrigerant heat exchanged by the finned evaporator 22 evaporates into a low-temperature and low-pressure gas and returns to the compressor 24 through the suction pipe, and circulates in sequence; so that the environment in the mushroom house is maintained at a certain temperature.

[0055] When the temperature sensor in the edible mushroom room senses that the temperature is too low, the temperature sensor transmits a signal to the electric control box to turn off the compressor 24.

[0056] It is worth mentioning that when the temperature outside the mushroom room is significantly lower than the temperature inside the mushroom room, the purpose of cooling can be achieved directly by introducing fresh air.

[0057] The control process of CO2 concentration: When the CO2 concentration sensor installed in the edible mushroom room detects that the CO2 concentration is too high, the CO2 concentration sensor transmits a signal to the CO2 concentration control unit in the control cabinet 21, and the CO2 concentration control unit immediately transmits an opening instruction to the air valve actuator 23. The air valve actuator 23 automatically opens after receiving the signal, and the air valve actuator 23 drives the first connecting shaft 18 to rotate 90°, and rotates the fresh air sealing plate 17 90° through the second connecting shaft 19, thereby covering the first return air outlet, so that the fresh air channel is opened. The outdoor fresh air with low CO2 concentration is mixed with the indoor air entering the second chamber 12 through the second return air port on the side through the fresh air inlet 14, the air filter and the vent 30 in sequence; the air filter filters the impurities in the air sucked out of the edible mushroom house, making the recovered air cleaner; the mixed air exchanges heat and mass with the refrigerant in the pipe in the finned evaporator 22, the water in the air is analyzed and the temperature is reduced; the fresh and low-temperature air is sent into the edible mushroom house through the blower 20, taking away the carbon dioxide and heat generated by the edible mushrooms during the growth process, so that the environment in the mushroom house maintains a certain temperature and carbon dioxide concentration.

[0058] When the carbon dioxide concentration sensor installed in the edible mushroom room detects that the carbon dioxide concentration is too low, the CO2 concentration sensor transmits a signal to the CO2 concentration control unit in the control cabinet 21, and the CO2 concentration control unit immediately transmits a closing command to the air valve actuator 23. The air valve actuator 23 automatically closes after receiving the signal, and the air valve actuator 23 drives the first connecting shaft 18 to rotate 90°, and rotates the fresh air sealing plate 17 90° through the second connecting shaft 19, thereby covering the vent 30, so that the fresh air channel is closed.

[0059] In this way, the temperature and carbon dioxide concentration in the air are monitored in real time by the temperature sensor and carbon dioxide concentration sensor installed in the mushroom house, and the compressor 24 and the air valve actuator 23 can be controlled to be turned off or on, so that the environment in the mushroom house maintains a certain temperature and carbon dioxide concentration.

[0060] Although the embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and cannot be understood as limiting the present invention. A person skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present invention without departing from the principles and purpose of the present invention.
