[0002] Traditional anaerobic culture equipment mostly adopts static culture or simple oscillation culture method, but there are some deficiencies in practical application. For example, static culture is easy to cause uneven distribution of culture, affecting the culture effect; simple oscillation culture can improve this problem, but due to the single oscillation mode, it cannot provide both rotation and translation motion modes, which may limit the growth efficiency of some microorganisms under strict anaerobic conditions. In addition, the traditional equipment often lacks effective temperature, humidity and gas composition control means, as well as intelligent management function, which limits the flexibility and controllability in the culture process.

[0003] With the development of science and technology, the field of microorganism research puts forward higher requirements for anaerobic culture equipment, not only needing to provide a more uniform mixing environment, but also having precise temperature and humidity control capability, and an efficient gas exchange system.

Users can conveniently set and monitor various operating parameters through the touch screen.

[0052] The dual-mode cooling and heating control system 5 is implemented using a commonly used technical solution in the prior art, and the following specific implementation methods and technical details can be used:

[0053] ① Heating system, which has heating elements and temperature sensors.

[0054] Heating elements: usually heating wires or heating plates, these elements can quickly respond to temperature control instructions and quickly increase the temperature inside the box.

[0055] Temperature sensor: The built-in temperature and humidity sensor can detect the temperature changes in the box in real time and feed the data back to the control system so that the working status of the heating element can be adjusted in time.

[0056] ②Refrigeration system: includes refrigeration elements.

[0057] Refrigeration elements: usually semiconductor refrigeration sheets (such as Peltier elements) or small compressor refrigeration systems are used. These elements can effectively reduce the temperature inside the box.

[0058] The cooling element is also managed by the control system. When the temperature sensor detects that the temperature is higher than the set value, the control system will activate the cooling element to reduce the temperature.

[0059] ③Humidity control: Humidity control is achieved through humidifiers and dehumidifiers.

[0060] Humidifier: Used to increase the humidity of the air in the box, usually through water vaporization or spraying.

[0061] Dehumidifier: Used to reduce the humidity of the air in the box, and can remove excess moisture through adsorbents or condensation.

[0062] ④Control system:

[0063] Microprocessor / controller: Serving as the core control unit, it receives sensor data, calculates and issues commands to components such as the heating element, cooling element, humidifier, and dehumidifier. This is a commonly used component in the prior art and will not be described in detail here.

[0064] Operating Principle: The motor is connected to the rotating shaft of the mesh tray 21 via a drive belt 25. When the servo motor 24 is activated, the drive belt 25 drives the mesh tray 21 to rotate smoothly. Multiple centrifuge tube storage grids 22 are used to hold sample containers to be cultured. During rotation, the sample containers are subjected to uniform mechanical force, promoting mixing of the culture medium. During use, the protective cover 23 prevents external contamination and is tightly secured by a movable latch 232 that engages with the positioning slots on the mesh tray 21. The operation of the vibrator causes the centrifuge tube rack 4 mounted on top to oscillate horizontally, enhancing sample mixing. The dual-mode heating and cooling control system 5 automatically adjusts the operating status of the heating or cooling elements by receiving data signals from temperature and humidity sensors. The sensor assembly 7 integrates multiple sensors, including but not limited to temperature and humidity sensors, carbon dioxide concentration sensors, and mixed gas concentration sensors. These sensors monitor the environmental parameters within the chamber in real time and transmit the data to the control system for analysis and processing. The microcomputer touch screen 11 allows users to set and monitor various operating parameters such as temperature, humidity, oscillation speed, and rotation frequency. In addition, the touch screen is also connected to safety mechanisms such as overload protection, leakage protection and over-temperature protection to ensure the safe and stable operation of the equipment.
