Abstract
Description
Technical Field
[0001] This utility model belongs to the field of uniform air supply to different heights inside a fermentation chamber, and relates to a device for uniformly supplying air to different heights inside a fermentation chamber. Background Technology
[0002] Fermentation chambers are facilities for the cultivation of microorganisms and serve as laboratories that combine teaching and research. They are primarily used for undergraduate professional experiments, practical training experiments, innovative experiments, graduate professional experiments, research by laboratory teachers, and social services. Furthermore, fermentation chambers are also used in fermentation processes in the food, alcohol, pharmaceutical, and biomass industries. The most crucial aspect of using a fermentation chamber is controlling the required temperature and humidity to maintain an optimal fermentation environment. Currently, the temperature and humidity inside fermentation chambers are regulated by air conditioning. Air conditioning, or air conditioners, refers to devices that artificially regulate and control parameters such as temperature, humidity, cleanliness, and airflow within a building or structure. Most air conditioners utilize refrigerants, which evaporate or condense, thereby causing the surrounding air to evaporate or condense, thus altering the temperature and humidity.
[0003] However, existing air conditioners, whether wall-mounted, floor-standing, or central, have fixed and uniformly positioned air outlets. This causes rapid temperature changes at the location directly opposite the outlet, while other areas require slow adjustment through air circulation. If the outlet for delivering cold air is at a low position, the cold air cannot be delivered to higher positions; conversely, if the outlet for delivering hot air is at a high position, the hot air cannot be delivered to lower positions. This results in a significant temperature difference between the upper, middle, and lower layers of the fermentation chamber. Furthermore, the temperature difference between the areas far from the outlet and those directly opposite it is also substantial. Since the air conditioner delivers humid air to regulate humidity within the fermentation chamber, this creates a significant humidity difference between the upper, middle, and lower layers. These conditions lead to uneven product fermentation and may even cause fermentation failure. Therefore, to address these technical problems, the technical solution described in this application was developed. Utility Model Content
[0004] The purpose of this invention is to provide a device for uniformly supplying air to different heights inside a fermentation chamber, thereby solving the aforementioned technical problems.

These sets of temperature and humidity monitors are evenly spaced along the height of the fermentation chamber, and the temperature and humidity monitors in the same set are sequentially installed along the length of the fermentation chamber.
[0012] Furthermore, one side of the fermentation chamber is connected to a return air vent, which is located on the side away from the air supply structure and is connected to the air conditioner through a return air duct.
[0013] Furthermore: the air supply structure is connected to the inner wall of the fermentation chamber through a fixing component, which includes a fixing frame and a fixing strap.

[0024] The features and performance of this utility model will be further described in detail below with reference to the embodiments.
[0025] Example 1
[0026] This utility model discloses a device for uniformly supplying air to different heights inside a fermentation chamber, such as... Figure 1 , Figure 2As shown, the system includes a horizontally arranged fermentation chamber 1, inside which a fermentation rack 2 is placed. A first air supply duct 3 of an air conditioner is connected to the outer wall of the fermentation chamber 1. Several air supply structures are connected to the inner wall of the fermentation chamber 1. These air supply structures are evenly spaced along the length of the fermentation chamber 1, and each air supply structure is vertically arranged along the height of the fermentation chamber 1. The air inlets of these air supply structures are connected to the first air supply duct 3. Several sets of air outlets 4 are arranged on the outer wall of each air supply structure. These sets of air outlets 4 are arranged sequentially from top to bottom along the air supply structure and all face the location of the fermentation rack 2. Several air outlets 4 in the same group are arranged sequentially at the same height along the air supply structure. Each set of air outlets 4 is equipped with an adjustment component for adjusting the size of the air outlet 4. The adjustment component is movably connected to one of the air outlets 4.
[0027] The specific implementation method of this embodiment is as follows: Several air supply structures are arranged along the length of the fermentation chamber, and these air supply structures are vertically arranged along the height of the fermentation chamber. Furthermore, several sets of air outlets are arranged from top to bottom on each air supply structure. The purpose of this arrangement is to provide multiple air outlets for supplying air generated by the air conditioner into the fermentation chamber. These air outlets are evenly distributed at different heights (upper, middle, and lower) within the fermentation chamber, and all face the location of the fermentation rack. These air outlets are arranged sequentially along the length of the fermentation chamber. The advantage of this arrangement is that there are multiple air outlets inside the fermentation chamber, and these outlets… The air vents are evenly distributed inside the fermentation chamber, thus avoiding the problem of large temperature differences at different heights caused by the single location of the air supply in existing air conditioning systems. This application further provides adjustment components on each group of air vents. The purpose of the adjustment components is to make the air vents at different heights have different sizes. The purpose of this arrangement is to make several groups of air vents have similar air volume (since the upper air vents are close to the first conveying pipe, the air volume of these air vents is larger, so the diameter of these air vents needs to be adjusted to be smaller, and the diameter is gradually increased from top to bottom along the air supply structure, so that the air volume of each group of air vents is basically similar).
[0028] Preferably, each second air supply pipe is equipped with a constant air volume valve at the connection point between it and the first air supply pipe. The constant air volume valve ensures that the air supply force delivered by the air conditioner is evenly distributed inside each second air supply pipe. The advantage of this setting is that the air force is further evenly blown to different heights inside the fermentation chamber.
[0029] Example 2
[0030] This utility model discloses a device for uniformly supplying air to different heights inside a fermentation chamber, such as... Figure 1 , Figure 2 As shown, the air supply structure includes a second air supply pipe 5, the upper end of which is connected to the first air supply pipe 3, the lower end of which is closed, and several sets of air outlets 4 are respectively opened on the second air supply pipe 5.
[0031] The adjustment assembly includes an adjustment column 6, the outer wall of which is interference-fitted with the air outlet 4, the front end of which passes through one of the air outlets 4 and is connected to a baffle 7, the baffle 7 being located inside the second air supply pipe 5, and the size and shape of the baffle 7 matching the size and shape of the inner wall of the second air supply pipe 5.
[0032] The rear end of the adjusting column 6 is provided with an adjusting handle 8. The inner wall of the adjusting handle 8 is machined with internal threads, and the outer wall of the rear end of the adjusting column 6 is provided with external threads. The adjusting handle 8 and the adjusting column 6 are connected by threads.
[0033] The specific implementation method of this embodiment is as follows: several sets of air outlets are set on the second air supply pipe, and the lower end of the second air supply pipe is closed to avoid the problem of air force being directly output through the lower end. At the same time, the upper end of the second air supply pipe is used to connect with the first air supply pipe.
[0034] The adjustment column is designed to pass through an air outlet and be interference-fitted with it. This design requires an operator to make adjustments, thus preventing the adjustment column from sliding along the air outlet. The baffle connected to the front end of the adjustment column facilitates the adjustment of the air outlet size.
[0035] The adjustment handle facilitates the movement of the adjustment column by the operator. The adjustment handle is threadedly connected to the adjustment column, which helps to further secure the connection between the adjustment column and the air outlet. When it is necessary to move the position of the adjustment column, the adjustment handle is loosened to facilitate the movement of the adjustment column. After the movement is completed, the adjustment handle is tightened to secure the adjustment column.
[0036] Example 3
[0037] This utility model discloses a device for uniformly supplying air to different heights inside a fermentation chamber, such as... Figure 1 As shown, several sets of temperature and humidity monitors 9 are provided on the inner walls of both sides along the length of the fermentation chamber 1. The several sets of temperature and humidity monitors 9 are set at equal intervals along the height of the fermentation chamber 1, and the temperature and humidity monitors 9 of the same set are set sequentially along the length of the fermentation chamber 1.
[0038] One side of the fermentation chamber 1 is connected to a return air vent 10, which is located on the side away from the air supply structure. The return air vent 10 is connected to the air conditioner through a return air duct 11.
[0039] The air supply structure is connected to the inner wall of the fermentation chamber 1 through a fixing component. The fixing component includes a fixing frame 12 and a fixing strap 13. The fixing end of the fixing frame 12 is locked to the inner wall of the fermentation chamber 1 by screws. One side of the fixing strap 13 is fixedly connected to the top of the fixing frame 12. The two ends of the fixing strap 13 are locked to the outer wall of the air supply structure by studs and nuts.
[0040] The specific implementation method of this embodiment is as follows: by setting temperature and humidity monitors at different heights in the fermentation chamber, the temperature and humidity at different heights in the fermentation chamber can be monitored. When the temperature or humidity at a certain height is detected to be abnormal, it is convenient for the operator to make timely adjustments, so that the temperature and humidity at different heights in the fermentation chamber are similar, and ultimately the temperature and humidity required for fermentation can be met.
[0041] The return air vents and ducts facilitate the recycling of air from inside the fermentation chamber. This avoids the air conditioner completely absorbing outside air, resulting in a smaller temperature and humidity difference between the outside and the inside of the fermentation chamber, thus providing a stable environment for the fermentation chamber.
[0042] The fixing frame and fixing straps facilitate the further fixing of several second air supply pipes, making the connection between the second air supply pipes and the inner wall of the fermentation chamber more stable.
[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. The present utility model is also applicable to other cabins or rooms that require uniform adjustment. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
