Description

Technical Field

[0001] This utility model relates to the field of mushroom cultivation technology, and in particular to a uniform airflow organization system for *Agaricus bisporus*. Background Technology

[0002] Currently, the industrialized production of *Stropharia masticata* (large king oyster mushroom) primarily uses a soil-covered cultivation method. The ventilation system is similar to that used for conventional mushroom cultivation, with fresh air supplied directly to the room via air handling units or fans, and exhaust using positive pressure. While this structure is simple, it has several drawbacks for *Stropharia masticata* cultivation. First, this airflow system results in uneven distribution of fresh air and limited penetration into the substrate, leading to carbon dioxide buildup around the spawn and inhibiting spawn growth. Second, the temperature of the supplied fresh air is uneven, and temperature differences can cause condensation, which drips and contaminates the spawn, affecting mushroom growth. Finally, conventional airflow systems cannot provide directional fresh air, resulting in uneven airflow distribution within the mushroom house. This leads to variations in yield, appearance, and size of mushrooms grown in different locations, resulting in a large number of substandard mushrooms. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a uniform airflow organization system for *Agaricus bisporus*, which can achieve uniform air delivery and enhance airflow penetration, thereby improving the stability and economic benefits of factory production.

[0004] A uniform airflow organization system for *Agaricus bisporus*, comprising,

[0005] The blower is located outside the mushroom house, and its air outlet is connected to the inside of the mushroom house.

[0006] An air cooler is installed inside the mushroom house, with its return air vent connected to the air supply vent of the blower. The air cooler is used to pre-cool or preheat the fresh air supplied into the mushroom house.

[0007] The air duct is installed inside the mushroom house; two adjacent rows of mushroom racks inside the mushroom house constitute a blowing unit, and each blowing unit is equipped with one air duct. The air duct is arranged between the two rows of mushroom racks in a blowing unit and is located above the mushroom racks; the inlet of the air duct is connected to the outlet of the air cooler, and multiple air outlets are provided along its axial direction on the air duct, and the air outlets are evenly distributed on its left and right sides.

[0008] The exhaust fan is installed inside the mushroom house, and its exhaust vent is connected to the outside of the mushroom house.

[0009] Preferably, an air distribution mesh is provided between the air outlet of the air cooler and the inlet of the air duct.

[0010] Preferably, the air cooler is a single-sided air cooler, with its return air vent directly connected to the supply air fan.

[0011] Preferably, the duct is a fabric duct.

[0012] Preferably, the system includes a controller, a temperature and humidity sensor, and a carbon dioxide concentration sensor. The temperature and humidity sensor and the carbon dioxide concentration sensor are installed inside the mushroom house and are connected in communication with the controller. The controller is used to automatically start and stop the blower and / or exhaust fan according to the carbon dioxide concentration in the mushroom house or a preset cycle.

[0013] Preferably, the exhaust fan is equipped with a filter screen on the side connected to the mushroom house.

[0014] Preferably, the air outlets on both sides of the air duct supply air from both sides above the mushroom rack.

[0015] This invention employs the above-mentioned solution, drawing in fresh air from outdoors via a blower, purifying and filtering it, and then delivering it to the return air vent of a cooler, thus reducing the probability of fungal contamination. The cooler then pre-cools / heats the fresh air, reducing the temperature difference between the fresh air and the indoor environment, preventing stimulation of the fungal growth and the production of substandard mushrooms. After pre-cooling / heating, the fresh air enters the ductwork, allowing for more concentrated airflow to designated areas in the mushroom house, preventing direct airflow from affecting the fungal growth and ensuring more even airflow throughout the room. Finally, after circulating within the mushroom house, the fresh air is exhausted outdoors by an exhaust fan, promoting air circulation. This effectively regulates the temperature, humidity, and CO2 concentration within the mushroom house, providing a reliable environmental guarantee for the industrialized cultivation of *Agaricus bisporus*, improving the growth quality and yield of *Agaricus bisporus* within the mushroom house.

[0020] The embodiments of this utility model are described in detail below.

[0021] Example 1:

[0022] As shown in Figure 1, this embodiment discloses a uniform airflow organization system for *Agaricus bisporus*, including a blower 1, located outside the mushroom house, with its air outlet connected to the inside of the mushroom house; a cooler 2, located inside the mushroom house, with its return air outlet connected to the air outlet of the blower 1, the cooler 2 being used to pre-cool or preheat the fresh air supplied to the mushroom house; an air duct 4, located inside the mushroom house; two adjacent rows of mushroom racks 5 inside the mushroom house constitute a blowing unit, each blowing unit being equipped with one air duct 4, the air duct 4 being arranged between the two rows of mushroom racks 5 in a blowing unit, located above the mushroom racks 5; the inlet of the air duct 4 being connected to the outlet of the cooler 2, the air duct 4 having multiple outlets along its axial direction, and the outlets being evenly distributed on its left and right sides; and an exhaust fan 6, located inside the mushroom house, with its exhaust outlet connected to the outside of the mushroom house.

[0023] The blower 1 is a fresh air unit that draws in fresh air from outdoors, purifies and filters it, and then sends it to the return air vent of the evaporative cooler 2. This fresh air intake controls the carbon dioxide concentration inside the mushroom house. Furthermore, the fresh air unit has a purification function, which reduces the probability of contamination of the mushroom spawn.

[0024] In this embodiment, a cooler 2 is used to pre-cool or preheat the fresh air supplied by the blower 1, reducing the temperature difference between the fresh air and the indoor temperature and avoiding stimulation of the spawn growth, resulting in substandard mushrooms. In a specific embodiment, a temperature sensor is installed in the mushroom house to detect the temperature inside, allowing the cooler 2 to adjust its operation based on the temperature. In a preferred embodiment, a uniform air distribution net 3 is installed between the air outlet of the cooler 2 and the inlet of the duct 4. By setting the uniform air distribution net 3, the air volume supplied from the cooler 2 into the corresponding duct 4 is evenly distributed, which is beneficial for more uniform air volume throughout the room. In a specific embodiment, a uniform air distribution net 3 is installed at the inlet of the duct 4 of each blowing unit. In a preferred embodiment, the cooler 2 is a single-sided cooler, which only needs to pre-cool / heat the fresh air in the mushroom house; the return air outlet of the cooler 2 is directly connected to the blower 1, which can shorten the fresh air access path.

[0025] In this embodiment, the air duct 4 is a fabric duct, which is easy to arrange. Figure 2 is a schematic diagram of the mushroom rack 5. The arrows indicate the airflow direction. The air duct 4 has openings on both sides. The air from the air duct 4 on the side closest to the wall is blocked and flows downwards. The air in the lower part of the mushroom house near the wall is compressed and moves towards the middle of the mushroom house. Thus, based on Bernoulli's principle, an air circulation is formed in the mushroom house, and fresh air circulates evenly between the cultivation layers of the mushroom rack 5.

[0026] The exhaust fan 6 connects the inside and outside of the mushroom house. In this embodiment, the exhaust fan 6 is a powered exhaust fan, which is controlled by a controller to start and stop actively exhausting air out of the mushroom house or stopping exhausting air out of the mushroom house, thereby promoting air circulation inside the mushroom house. Preferably, a filter screen is provided on the side of the exhaust fan 6 that connects to the inside of the mushroom house. The filter screen is used to filter the spores in the mushroom house, preventing them from entering the exhaust fan 6 and damaging it.

[0027] The system in this embodiment includes a controller and a carbon dioxide concentration sensor. The carbon dioxide concentration sensor is installed in the mushroom house and is connected to the controller in communication. The controller is used to automatically start and stop the blower 1 and / or the exhaust fan 6 according to the carbon dioxide concentration in the mushroom house or a preset cycle, so as to control the carbon dioxide concentration in the mushroom house at a level suitable for the growth of *Agaricus bisporus*, thereby improving the growth quality and yield of the mushrooms.

[0028] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
