Description

Technical Field

[0001] The invention relates to the technical field of edible fungus production, and in particular to an automated production and inoculation system for edible fungus liquid strains. Background Art

[0002] As a kind of agricultural product with great economic and nutritional value, edible fungi have received widespread attention and popularity around the world. In recent years, with the continuous growth of market demand, the edible fungi industry has developed rapidly. As a key technology in the cultivation of edible fungi, liquid culture technology has gradually become a research hotspot and development direction in the field of edible fungi production due to its advantages of fast germination, rapid growth, and uniform age. However, there are still many problems to be solved in the production and inoculation process of edible fungi liquid culture, which seriously restricts the further promotion and application of this technology.

[0003] In the production of liquid strains, the low degree of automation is a prominent problem. In the traditional production method, the preparation of the culture medium mainly relies on manual weighing and mixing, which is not only labor-intensive and inefficient, but also difficult to ensure the consistency and accuracy of the components of each batch of culture medium, thus affecting the growth and quality of liquid strains. During the sterilization process, the control of key parameters such as temperature, pressure and time is not precise enough, which can easily lead to incomplete sterilization or excessive sterilization. The former will cause contamination by foreign bacteria, and the latter can destroy the nutrients in the culture medium and reduce the vitality of the strain. The inoculation operation is usually carried out in an open or semi-open environment. Manual inoculation will inevitably introduce foreign bacteria, increasing the risk of contamination. At the same time, due to the lack of effective automated equipment, the efficiency and accuracy of the inoculation process cannot be guaranteed.

[0004] During the cultivation stage, existing cultivation equipment has limited ability to monitor and adjust environmental parameters. Environmental factors such as temperature, humidity, and oxygen content are crucial to the growth of liquid strains, but traditional cultivation equipment often cannot control these parameters in real time and accurately, resulting in an unstable growth environment for the strains, affecting the growth rate and quality of the strains. In addition, manual operation makes it difficult to achieve continuous and detailed monitoring of the cultivation process, and it is impossible to detect and handle abnormal situations in a timely manner, further reducing the success rate of liquid strain production.

[0005] In the inoculation process, the existing inoculation methods have the problem of uneven inoculation amount. During manual inoculation, due to differences in the technical level and experience of operators, it is difficult to ensure the consistency of the inoculation amount at each inoculation point, which will lead to inconsistent growth rates and large differences in yields during the growth of edible fungi, affecting the quality and economic benefits of the final product. In addition, the manual inoculation speed is slow and cannot meet the needs of large-scale production, limiting the large-scale development of the edible fungi industry.

[0006] The existing production and inoculation technologies for edible mushroom liquid spawn have many deficiencies such as low automation level, high risk of contamination by miscellaneous bacteria, uneven inoculation amount, and low production efficiency. There is an urgent need to develop a more advanced, efficient, and stable automated production and inoculation system to promote the sustainable development of the edible mushroom industry. Therefore, we propose an automated production and inoculation system for edible mushroom liquid spawn. Summary of the Invention

[0071] Code explanation:

[0072] The LiquidStrainProduction class: Simulates the liquid strain production module, including four steps: culture medium preparation, sterilization, inoculation, and cultivation. Each step has a corresponding method, and flags are used to ensure that operations are carried out in sequence.

[0073] The InoculationModule class: Simulates the inoculation module, including two methods: preparation and performing inoculation. The inoculation operation can only be performed when ready and the liquid strain has been cultured.

[0074] The ControlSystem class: Simulates the control system, responsible for coordinating the operation of the liquid strain production module and the inoculation module.

[0075] Main program: Creates an instance of the control system, and sequentially calls the methods of the production process and the inoculation process to complete the entire automated production and inoculation process.

[0076] Example 2: An automated production and inoculation system for edible mushroom liquid spawn, comprising a liquid spawn production module, an inoculation module, and a control system. The liquid spawn production module includes a culture medium preparation unit, a sterilization unit, an inoculation unit, and a cultivation unit. Culture medium preparation unit: It includes raw material storage tanks, metering devices, mixing tanks, and conveying pipelines. The raw material storage tanks are used to store various culture medium raw materials. The metering devices measure the dosages of the raw materials and convey them to the mixing tanks for thorough mixing to form a uniform culture medium. The conveying pipelines transport the mixed culture medium to the sterilization unit. Sterilization unit: High-temperature and high-pressure sterilization equipment is used, such as a high-pressure steam sterilizer. This equipment can thoroughly sterilize the culture medium and kill the miscellaneous bacteria and spores therein. The temperature, pressure, and time parameters during the sterilization process are precisely controlled by the control system. Inoculation unit: It includes a spawn storage tank, inoculation guns, and a sterile inoculation room. The spawn storage tank is used to store high-quality mother spawn. The inoculation guns inoculate the mother spawn into the sterilized culture medium in the sterile inoculation room. The inoculation process is carried out in a sterile environment, effectively avoiding contamination by miscellaneous bacteria. Cultivation unit: It is provided with multiple cultivation tanks, and the cultivation tanks are equipped with temperature sensors, humidity sensors, oxygen sensors, and stirring devices.

[0077] Based on the data fed back by the sensors, the control system adjusts the environmental parameters such as temperature, humidity, and oxygen content in the cultivation tanks in real time, providing suitable conditions for the growth of the liquid spawn. The stirring devices can fully mix the culture medium and the spawn, promoting the growth and reproduction of the spawn. The control system includes a central processing unit, sensors, and actuators. The sensors are distributed at various key positions in the liquid spawn production module and the inoculation module, collecting the environmental parameters such as temperature, pressure, humidity, oxygen content, and the operating status information of the equipment in real time, and transmitting this information to the central processing unit. The central processing unit analyzes and processes the received information, issues control instructions according to the preset program, and controls the operation of each unit and equipment through the actuators, realizing the automated operation of the entire system. The metering devices in the culture medium preparation unit use high-precision electronic scales with an accuracy of milligrams to ensure the accurate proportioning of the culture medium raw materials.

[0078] The high-temperature and high-pressure sterilization equipment in the sterilization unit is equipped with multiple safety protection devices, such as over-temperature protection and over-pressure protection, to ensure the safety and reliability of the sterilization process.

[0079] The inoculation robot uses a six-axis industrial robot, which has high flexibility and precision, and can adapt to the inoculation requirements of culture containers with different specifications and shapes.

[0080] The control system is also equipped with remote monitoring and operation functions. Operators can monitor the operating status of the system at any time and place through the Internet and perform remote operation and adjustment.
