Description

Technical Field

[0001] The invention relates to the field of temperature control, in particular to an edible fungus cultivation environment control device. Background Art

[0002] Mushrooms are common ingredients in our daily life. They are not only delicious and fragrant, but also rich in protein, vitamins and minerals. They have high nutritional value. Regular consumption of mushrooms can regulate the liver, kidney, spleen and stomach functions and prevent cardiovascular diseases. In addition, mushrooms also have high medicinal and health value. They can be made into tablets, syrups, capsules or ground into powder for consumption. There are many types of mushrooms with different shapes. Common edible mushrooms include mushrooms, shiitake mushrooms, oyster mushrooms, enoki mushrooms, black fungus, white fungus, etc.

[0003] With the continuous improvement of production level, the cultivation method of mushrooms has changed greatly, from relying on natural reproduction of fungi and harvesting in the wild during the mushroom season in the past, to gradually developing into greenhouse cultivation. Through the processes of nutrient preparation, compost fermentation, inoculation and covering, and mushroom management, mushrooms can be produced in large quantities. Greenhouse cultivation is easily affected by climate and is only suitable for seasonal production. It has large geographical constraints, low land utilization rate, and the yield and quality of mushrooms are difficult to control. At present, many mushroom cultivation factories adopt the cultivation method of mushroom sticks and mushroom bags, including mixing materials, bag making, high temperature sterilization, inoculation, cultivation, and mushroom cultivation. The advantages of this method are: production is carried out in mushroom bags, which is easy to carry and manage; the assembly line production process, each process is completed in different workshops, and the production efficiency is high.

[0004] During the mushroom cultivation process, the fruiting bodies are very sensitive to the external environment during the fruiting period. Temperature, humidity, light and carbon dioxide concentration will directly affect the differentiation and development level of the fruiting bodies, and then affect the yield, quality and economic benefits. Therefore, the control of the external environment of the mushroom bags during the fruiting period is particularly critical. When manually adjusting and controlling the temperature, humidity, light and carbon dioxide concentration, there are often defects such as poor timeliness, low accuracy and inability to cover all aspects. Some existing mushroom cultivation warehouses control the temperature and carbon dioxide concentration through control equipment, but in the process of controlling the carbon dioxide concentration, the temperature difference between the newly introduced external gas and the internal gas is large, which affects the growth of mushrooms; or another temperature regulating device is required to regulate the temperature of the newly introduced external gas, resulting in a large control device and high cost.

The water inlet pan 721 extends from the bottom of the inclined plate 720. The bottom of the internal heat exchange assembly 40 is located on the water inlet pan 721. The water inlet pan 721 can receive the condensed water generated on the internal heat exchange assembly 40. The water inlet tray 721 is provided with a water tank 7210 and an overflow port 7211.

[0039] The humidity control assembly 80 includes a humidifier 81 and a water inlet valve 82 . The humidifier 81 is installed on the water tank 7210 , and the water inlet valve 82 is installed on the housing 10 and communicated with the water tank 7210 .

[0040] The second exhaust fan 90 is fixed to the bottom of the housing 10 and is located on one side of the air outlet 12. The filter assembly 91 is located on one side of the air inlet 11 to filter the incoming gas. The external heat exchange assembly 92 is fixed inside the housing 10 and the space where the external heat exchange assembly 92 is located is separated from the space where the internal heat exchange assembly 40 is located.

[0041] The temperature sensor and the humidity sensor are installed at the air supply port 13, the first ventilation port 14, the second ventilation port 15 or the cultivation space on the back of the shell 10. The edible fungus cultivation environment control device is provided with a control module. The control module receives the signal of the sensor to obtain the real-time temperature and humidity in the cultivation space and can control the light intensity of the cultivation space.

[0042] In the assembled edible fungus cultivation environment control device, the first ventilation port 14, the internal heat exchange component 40, the first exhaust fan 50 and the air supply port 13 form a heat exchange channel; the air inlet 11, the side opening 62, the inside of the guide 60, the upper opening 61 and the first ventilation port 14 form an air inlet channel for adjusting the CO2 concentration, and the air inlet channel surrounds the internal heat exchange component 40. The second ventilation port 15, the guide 60, the bottom opening 63, the second exhaust fan 90 and the air outlet 12 form an air outlet channel for adjusting the CO2 concentration. The air inlet channel is located between the heat exchange channel and the air outlet channel.

[0043] When the edible fungus cultivation environment control device is used, the temperature sensor monitors the temperature of the cultivation space. When the temperature is lower than the preset value, the gas in the cultivation space enters the heat exchange channel through the first ventilation port 14, is heated by the internal heat exchange component 40, and then returns to the cultivation space through the first exhaust fan 50 and the air supply port 13, and the temperature of the cultivation space rises. When the temperature is higher than the preset value, the switching valve 30 is switched, and the gas in the cultivation space enters the heat exchange channel through the first ventilation port 14, is cooled by the internal heat exchange component 40, and then returns to the cultivation space through the first exhaust fan 50 and the air supply port 13, and the temperature of the cultivation space decreases.

[0044] During the heat exchange process, if the humidity of the cultivation space is lower than the preset value, the humidifier 81 works to increase the humidity of the heat exchanged gas. When the temperature of the cultivation space is appropriate, the internal heat exchange component 40 does not work and only increases the humidity of the gas.

[0045] When the CO2 concentration in the cultivation space is too high, the external gas enters from the air inlet 11, and enters the cultivation space from the side opening 62, the inside of the guide 60, the upper opening 61 and the first ventilation port 14. During the flow through the air inlet channel, the gas absorbs the heat of the heat exchange channel to increase or decrease the temperature, so that the temperature difference between the external air and the cultivation space is reduced. The gas in the cultivation space flows out from the second ventilation port 15, the guide 60, the bottom opening 63, the second exhaust fan 90 and the air outlet 12. During the outflow process, the temperature of the gas is absorbed by the gas in the air inlet channel, reducing heat loss.

[0046] The edible fungus cultivation environment control device adjusts the temperature of the edible fungus cultivation space through the heat exchange channel. During the CO2 concentration adjustment process, the external gas entering the edible fungus cultivation space can absorb the heat of the heat exchange channel to increase or decrease the temperature when passing through the air inlet channel, thereby adjusting the temperature of the external gas entering the edible fungus cultivation space to avoid excessive temperature difference that affects the growth of edible fungi, and no additional temperature adjustment device is required, making the overall size of the equipment small and the cost low.

[0047] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of them belong to the protection scope of the present invention.
