[0019] Please see Figures 1-6 This application provides a technical solution: a filling machine with a built-in petri dish holding rack, including a filling machine body 110, a frame 120, a longitudinal linear module 130, a robot arm 140, a tray 150, a vertical plate 160 and a holding plate 191. The frame 120 is fixed inside the filling machine body 110, and the longitudinal linear module 130 is installed on the frame 120. One end of the robot arm 140 is fixed to the slider of the longitudinal linear module 130. Two robot arms 140 are mounted on the frame 120 and are symmetrically arranged. The tray 150 has several openings that can simultaneously hold several culture dishes. The tray 150 is mounted on the other end of the robot arm 140. The upright plate 160 is fixed inside the bracket of the filling machine body 110. There are six upright plates 160 arranged around the inner cavity of the filling machine body 110. Several ventilation openings 170 are opened on the upright plate 160 and are linearly and equidistantly arranged. The stationary plate 191 is fixed on the upright plate 160 and has a first threaded hole 180. The mounting hole on the stationary plate 191 corresponds to the first threaded hole 180. The first threaded hole 180 is used to install the stationary plate 191 onto the upright plate 160. The upright plate 160 is provided with a second threaded hole 190, which is corresponding to the mounting hole on the bracket of the filling machine body 110. There are several second threaded holes 190 and several stationary plates 191. The stationary plates 191 are linearly and equidistantly arranged on the upright plate 160. It also includes a material hopper 192, which is fixed on the outer wall of the bracket of the filling machine body 110. The material hopper 192 is used to place the culture dish.

[0020] Ventilate the culture medium in the petri dish: I. Meeting the gas metabolism needs of microorganisms Different microorganisms have different requirements for gases (such as oxygen and carbon dioxide), and ventilation is the key to achieving gas supply and exhaust. Aerobic bacteria culture: Most common microorganisms (such as Escherichia coli, Bacillus subtilis, etc.) are aerobic bacteria, which require continuous oxygen consumption and release carbon dioxide during their growth. Ventilation can introduce external oxygen, supplement the oxygen content around the culture medium, and prevent slow growth, abnormal metabolism, or even death of microorganisms due to hypoxia.

[0021] Facultative anaerobic / microaerophilic bacteria cultivation: Facultative anaerobic bacteria (such as yeast) can grow in aerobic or anaerobic environments, but they reproduce faster under aerobic conditions (producing more energy through aerobic respiration); Microaerophilic bacteria (such as Helicobacter pylori) require a low-oxygen environment, and ventilation can be used to adjust the oxygen concentration by controlling the ventilation volume to match their growth needs.

[0022] Expelling harmful metabolic gases: If gases such as carbon dioxide and hydrogen sulfide produced by microbial metabolism accumulate in the petri dish, they will change the local gas composition and inhibit the growth of the microorganisms themselves or other coexisting microorganisms. Ventilation can remove them in time.

[0023] II. Adjusting the physicochemical properties of the culture medium to maintain a stable growth environment. pH control: Carbon dioxide produced by microbial metabolism dissolves in the culture medium to form carbonic acid, causing the pH value to drop (become more acidic). Excessive acidity will inhibit the growth of most microorganisms. Ventilation can remove carbon dioxide, reduce its solubility in the culture medium, and help maintain the pH value within the range suitable for microorganisms (most bacteria are suitable for pH 7.2-7.6, and fungi are suitable for pH 4.0-6.0).

[0024] Reduce the impact of condensation: During cultivation (especially at constant temperature), condensation easily forms on the inner wall of the petri dish. If water droplets fall into the culture medium, it can cause colony diffusion and abnormal morphology, affecting counting or observation. Ventilation can promote air circulation within the petri dish, reduce local humidity, and decrease condensation.

[0025] III. Reduce contamination risks and ensure culture purity Reduce the "anaerobic microenvironment" for the growth of contaminating bacteria: If the petri dish is sealed without ventilation, the localized hypoxic and high-humidity environment can become a "breeding ground" for anaerobic bacteria (such as Clostridium tetani) and other contaminating bacteria, leading to contamination. Introducing oxygen through ventilation (or adjusting the gas ratio) can inhibit the growth of anaerobic bacteria and reduce the probability of contamination.

[0026] Expelling metabolic signals from contaminating bacteria: If a small number of contaminating bacteria are present in the culture system, the gases produced by their metabolism (such as ammonia produced by some bacteria) may spread and affect the growth of the target bacteria. Ventilation can accelerate the removal of these harmful signals and reduce the impact of contamination.

[0027] IV. Requirements for Adapting to Specific Cultivation Scenarios Uniform growth in solid culture media: In solid culture media (such as agar medium), microorganisms mainly grow on the surface. Ventilation can ensure that the gas concentration in each area of ​​the culture medium surface is uniform, avoiding uneven colony growth and inconsistent sizes due to insufficient local gas, which facilitates subsequent counting, isolation or morphological observation.

[0028] Stability of large-scale or long-term culture: If batch culture (such as culturing multiple petri dishes at the same time) or long-term culture is carried out, ventilation can maintain the gas balance of the entire culture environment (such as in the incubator), avoid the deterioration of the overall environment due to multiple petri dishes consuming oxygen and releasing carbon dioxide, and ensure the stable growth of microorganisms in all petri dishes.

[0029] The working principle and process of this utility model are as follows: In use, the longitudinal linear module 130 drives the tray 150 to move up and down. The robotic arm 140 moves the tray 150 in multiple directions. The filling machine body 110 moves the culture dish and its lid to a designated position with the culture dish on top and the lid directly below, thus injecting the culture medium into the culture dish. Under the combined action of the longitudinal linear module 130 and the robotic arm 140, the tray 150 lifts the culture dish and its lid onto the settling plate 191 for settling. After a designated settling time, the settling culture dish and its lid are then moved back to a designated position within the filling machine body 110 by the longitudinal linear module 130 and the robotic arm 140. The longitudinal linear module 130 and the robotic arm 140 work again to move another set of settled petri dishes onto the previous set, thus sealing the petri dishes. Then, the capped petri dishes are moved out of the filling machine body 110 by the conveyor. The vent 170 ensures crosswind circulation within the filling machine body 110, ventilating the culture medium in the petri dishes, creating a suitable gaseous environment for microbial growth, regulating physicochemical conditions, and reducing the risk of contamination. This filling machine with built-in petri dish settling rack uses the longitudinal linear module 130, robotic arm 140, and tray 150 to replace manual labor, freeing up manpower. The multiple settling plates 191 reduce the overall size of the equipment, save space in the factory, and provide users with a better user experience.

[0030] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
