Description

Technical Field

[0001] This utility model belongs to the field of plant biotechnology, and specifically relates to a reactor for staged plant cultivation with liquid storage. Background Technology

[0002] A plant culture reactor is a bioreactor used for the culture of plant cells, tissues, or organs. It can simulate the environmental conditions of plants at different growth stages, providing precise control and optimization for plant culture to achieve efficient and large-scale plant culture. Staged plant culture reactors provide suitable growth conditions for plant cells, tissues, or organs by precisely controlling various parameters in the culture environment, such as temperature, light, humidity, gas composition, and nutrient supply. At different culture stages, these parameters can be automatically adjusted according to the growth needs of the plant to promote plant growth, development, and the synthesis of metabolites.

[0003] Currently, most plant culture reactors on the market use solid culture methods, with agar in culture bottles as the culture medium. However, this method consumes a large amount of agar, and numerous containers need to be handled during filling and cleaning, which undoubtedly increases the complexity and labor intensity of the operation. Solid culture is cumbersome to change the culture medium, making it difficult to achieve precise management of the culture medium in stages. If not cleaned properly, there is a risk of cross-contamination, which to some extent limits the efficiency and quality of plant culture. Utility Model Content

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-4 As shown, a reactor for staged plant cultivation with liquid storage includes a tank body 1, a tank cover 2 installed on the top of the tank body 1, a plurality of internal threaded holes 3 on the top of the tank body 1, a plurality of internal threaded holes 4 for the cover to cooperate with the internal threaded holes 3, a sealing screw 5 threadedly connected to each internal threaded hole 3 and the internal threaded hole 4, and a classification culture component is provided inside the tank body 1.

[0022] The tank body 1 is designed to cultivate plant materials and hold nutrient solutions. The tank lid 2 is made of transparent material to facilitate light exposure for the plant materials. After the threaded hole 3 inside the tank body 1 aligns with the threaded hole 4 inside the lid 2, a sealing screw 5 secures the connection, ensuring a tight seal. The categorized cultivation component uses a partition 9 to divide the interior of the tank body 1, allowing for the storage of different nutrient solutions and controlled cultivation to meet the needs of different stages of plant cultivation. The design of the water-guiding partition 6 and water-guiding pipe 10 addresses the issue of contamination that can easily occur when changing the nutrient solution during the cultivation process.

[0023] like Figure 2 and Figure 3 As shown, the classification culture component includes a water guide baffle 6 fixedly connected to the inner cavity of the tank body 1, a water distribution plate 7 fixedly connected to the inner wall of the tank body 1 and at the top of the water guide baffle 6, a tank sealing ring 8 fixedly connected to the inner wall of the tank body 1 and at the bottom of the water guide baffle 6, four tank baffles 9 arranged in a circular array fixedly connected to the inner wall of the tank body 1 and at the bottom of the tank sealing ring 8, multiple water guide pipes 10 connected around the bottom of the water guide baffle 6, and a filter sterilization component connected to the surface of the tank body 1.

[0024] Specifically, the water-guiding baffle 6 is used to divide the interior of the tank body 1 into two parts: the upper part is for the cultivation of plant materials, and the lower part is for the storage of culture medium. The water-guiding pipe 10 is used to guide the culture medium to the upper part for cultivating plant materials. The water-distributing plate 7 is used to evenly disperse the culture medium discharged from the water-guiding pipe 10 at the bottom of the water-guiding baffle 6, preventing the discharged culture medium from impacting the plant materials and causing accumulation, which would affect plant growth. The tank body baffle 9 can evenly divide the lower part of the tank body into four parts, so that the bottom cavity of the tank body 1 has four spaces for storing liquid. Different types of culture medium can be stored in the four spaces to meet the requirements of different culture media at different stages of plant growth or the different cultivation conditions at different stages of plant growth. Different types of culture media can also be set up as needed. The system allows for the selection of different culture medium types to meet the needs of single or several stages of cultivation. The selected culture medium is introduced from the lower culture medium compartment (10) to the upper plant material compartment (6) via the water guide pipe 10. During this process, the design of the water distribution plate 7 ensures uniform dispersion of the culture medium, avoiding accumulation caused by direct impact on the plant material and guaranteeing uniform hydration and a suitable growth environment. Subsequently, as plant cultivation progresses, the culture medium type in the four spaces separated by the tank partition 9 at the bottom of the tank body 1 can be changed or adjusted according to the different growth stages of the plants. This satisfies the specific nutritional and environmental requirements of the plants at different growth stages, improving the efficiency and flexibility of plant cultivation and effectively avoiding the risk of contamination during the cultivation process.

[0025] like Figure 2 and Figure 3 As shown, the filtration and sterilization assembly includes a first tank pipe 11 connected to the surface of the tank body 1 and near the bottom of the tank cover 2. A first air filter 12 is connected to one side of the first tank pipe 11. Multiple second tank pipes 13 are connected to the surface of the tank body 1 and around the bottom of the water guide baffle 6. An air valve switch 14 is fixedly installed at one end of each second tank pipe 13. The end of the air valve switch 14 away from the second tank pipe 13 is connected to a second air filter 15. An air pump 16 is installed on one side of the tank body 1. The output end of the air pump 16 is connected to a silicone hose 17, and one end of the silicone hose 17 is connected to the second air filter 15. A time controller 18 is electrically connected to one side of the air pump 16.

[0026] The first air filter 12 is used to filter air, ensuring that the air entering and exiting the tank body 1 meets the sterility standard. The first tank connector 11 works in conjunction with the first air filter 12 to ensure air filtration and sterilization in the upper plant culture material area, effectively preventing microorganisms in the air from invading the culture environment, thereby maintaining the sterile conditions for plant culture. The second air filter 15 also has the function of filtering air, ensuring that the air in the lower part of the tank body 1 where the culture medium is placed is sterile, reducing the possibility of the culture medium being contaminated. The second tank connector 13 is responsible for connecting the second air filter 15 to the tank body 1. The air pump 16 provides the air pressure required for operation. The timer 18 operates the air pump 16 by controlling the on and off of the current, and controls the immersion culture cycle of the device by adjusting the on and off frequency of the current. The silicone hose 17 is used to connect the air pump 16 to the second air filter 15. The air valve switch 14 is used to adjust the air flow rate entering and exiting the tank body 1, ensuring that air can enter or exit the tank body 1 at a predetermined frequency and time interval during the immersion culture and aeration culture stages.

[0027] like Figure 3 and Figure 4 As shown, a grid 19 is fixedly connected to the inner wall of the tank body 1 and to the top of the water distribution plate 7.

[0028] Specifically, the grid 19 can further disperse the culture solution dispersed by the water distribution plate 7, ensuring that the plant material can fully absorb the nutrients in the culture solution and promote the healthy growth of the plant; at the same time, it can prevent the plant material from falling below the tank body 1.

[0029] like Figure 2 As shown, multiple tank sealing buckles 20 are fixedly installed on the inner wall of the tank body 1 and around the top of the water guide baffle 6. Each tank sealing buckle 20 has a triangular structure.

[0030] The tank sealing buckle 20 is used to limit and engage the water guide baffle 6, ensuring that the water guide baffle 6 is close to the tank sealing ring 8 and the tank baffle 9, so that the tank sealing ring 8 can seal the water guide baffle 6 with the protruding part of the inner wall of the tank body 1 and the tank baffle 9.

[0031] like Figure 1 As shown, a lid sealing ring 21 is fixedly connected to the bottom of the lid 2, and the surface of the lid sealing ring 21 is in contact with the top of the inner cavity of the can body 1.

[0032] Specifically, the lid sealing ring 21 is made of high-temperature and high-pressure resistant materials such as silicone to ensure the sealing effect between the lid sealing ring 21 and the top of the inner cavity of the can body 1, ensuring the sterility of the can body 1 and providing a reliable guarantee for the healthy growth of plant materials.

[0033] The working principle of this utility model is as follows: First, the plant material is placed on the water-guiding baffle 6. Then, the culture medium is injected into the four spaces separated by the tank baffle 9 at the bottom of the tank body 1. The culture medium is guided to the upper part through the water-guiding pipe 10 for culturing the plant material. The water-dividing plate 7 is used to evenly disperse the culture medium discharged from the water-guiding pipe 10 at the bottom of the water-guiding baffle 6, so that it comes into direct contact with the plant material. After a period of cultivation, if it is necessary to continue to use the remaining culture medium in the tank body 1 for cultivation, the second air filter 15 can be replaced and the corresponding air valve switch 14 can be opened, while the original air valve switch 14 is closed. This ensures that only one of the four air valve switches 14 in the lower part of the tank body 1 is always open. Then, cultivation continues, thus completing the cultivation of plants with a sufficient amount of culture medium for a long time.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
