Description

Technical Field

[0001] The invention relates to the technical field of rapid cold fermentation of organic matter, in particular to a method for controlling rapid cold fermentation of organic matter with EM bacteria. Background Art

[0002] The EM bacteria organic matter rapid cold fermentation control method is an organic matter fermentation technology based on EM flora, which aims to promote the rapid metabolism of EM bacteria by controlling environmental conditions, thereby accelerating the degradation and transformation of organic matter. In this method, the EM flora is composed of a variety of beneficial microorganisms, mainly including lactic acid bacteria, yeasts and photosynthetic bacteria. These microorganisms can be active at lower temperatures and effectively promote the degradation of organic waste by decomposing organic matter to produce organic acids, enzymes and other substances. Cold fermentation refers to controlling the temperature at a lower level (usually below room temperature, but not below 0°C) to reduce the loss of heat-sensitive components while maintaining the activity and metabolic efficiency of microorganisms. The system's control methods include temperature control, humidity regulation, ventilation control, etc. to achieve the best fermentation effect.

[0003] Although the EM bacteria organic matter rapid cold fermentation control method has a good effect in accelerating the decomposition of organic matter and improving resource utilization efficiency, it also has some defects. The microbial activity is low during the cold fermentation process, and the fermentation speed is slower than that of normal temperature fermentation, which may lead to a long fermentation cycle and affect the harvest time of the product. Secondly, this method has high requirements for environmental control, especially the precise control of temperature and humidity. If it is not properly controlled, it may lead to a decrease in the activity of the EM flora and even cause fermentation failure. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a method for controlling the rapid cold fermentation of EM bacteria organic matter, which solves the problem that the microbial activity is low during the cold fermentation process and the fermentation speed is slower than that of normal temperature fermentation. This method has high requirements for environmental control, especially the precise control of temperature and humidity. If the control is improper, it may lead to a decrease in the activity of the EM flora.

[0005] To achieve the above objectives, the present invention is implemented by the following technical scheme: a method for controlling rapid cold fermentation of organic matter with EM bacteria, comprising:

[0006] a. Providing an EM bacterial community, wherein the EM bacterial community includes lactic acid bacteria, yeast and photosynthetic bacteria, and selecting an EM bacterial community with good low temperature resistance to ensure that a high metabolic activity can be maintained in a low temperature environment to promote the degradation of organic waste;

[0007] b. preparing organic raw materials, which are agricultural and forestry wastes, kitchen waste or other organic wastes, and screening and processing different types of organic matter to ensure their suitable physical and chemical properties, so as to provide high-quality raw materials for subsequent cold fermentation;

[0008] c. Pre-treating the organic raw materials, including crushing, impurity removal, and humidity adjustment. The crushing step breaks down large organic matter into smaller particles to increase the contact area between the organic matter and the EM flora.

[0009] d. inoculating the EM bacterial flora into the pretreated organic raw material. The EM bacterial flora is usually added to the organic raw material in the form of liquid or dry powder to ensure uniform distribution of the EM bacterial flora and quickly start the fermentation process;

[0010] e. Place the inoculated organic raw materials into a fermentation container. The container needs to be airtight and able to regulate temperature and humidity to prevent interference from the external environment, ensure precise control of temperature and humidity, and meet the growth requirements of EM bacteria;

[0011] f. The temperature of the fermentation container is adjusted by an intelligent temperature control system to maintain it at 5°C to 15°C, wherein the temperature fluctuation range does not exceed ±1°C. The temperature control system includes a temperature sensor, a cooling device and a heating device, which can adjust the temperature in the fermentation container in real time to ensure the activity of the EM bacterial community;

[0013] h. Regularly or continuously monitor the metabolic activity of the EM bacteria during the fermentation process, and obtain the activity data of the bacteria through sensors. The sensors monitor multiple environmental parameters such as temperature, humidity, pH, and gas concentration to determine the activity of the EM bacteria and the progress of the fermentation;

[0014] i.

The system can adjust the environmental conditions in real time according to the bacterial activity feedback to ensure the metabolic efficiency of the EM bacteria;

[0015] j. Regularly or according to the real-time monitoring results, adjust the oxygen concentration in the fermentation container to ensure that the oxygen supply is not less than the set value of 5% to 10%. The precise control of oxygen concentration plays a key role in the metabolism of microorganisms, ensuring that the EM flora can fully exert its metabolic capacity under the condition of sufficient oxygen;

[0016] k. Lighting system: The light intensity is adjusted by the light source set in the reactor to further promote the growth and activity of EM bacteria. The right amount of light is conducive to the activity of photosynthetic bacteria and promotes the diversity and metabolic rate of the bacterial community;

[0017] l. After the fermentation cycle, the fermentation products are screened and tested to ensure that the product quality meets the predetermined standards, among which the organic matter content of organic fertilizers reaches more than 70%. Laboratory analysis and testing are carried out to ensure that the fermentation products meet the quality standards and are suitable for agricultural applications.

[0018] Preferably, the ratio of lactic acid bacteria, yeast and photosynthetic bacteria in the EM flora is 2:1:1.

[0019] Preferably, the organic raw material is crushed and adjusted to a particle size of 0.5 to 2 cm during pretreatment.

[0020] Preferably, the fermentation container is provided with a microclimate regulating device, which can adjust the temperature, humidity and oxygen concentration in real time during the fermentation process, and is fully automatically managed through a PLC control system. The fermentation container is a closed structure to prevent the external environment from interfering with the fermentation process.

[0021] Preferably, the lighting system promotes the metabolic activity of EM bacteria by adjusting the light intensity and cycle, thereby accelerating the fermentation rate.

[0022] Preferably, the fermentation product is an organic fertilizer or an organic liquid fertilizer, and the organic fertilizer has a high organic matter content and an excellent soil improvement effect.

[0023] Preferably, during the cold fermentation process, the activity of the EM flora is verified by regular sampling and enzyme activity testing to ensure the efficiency and stability of the fermentation process.

[0024] Preferably, the control method monitors and automatically adjusts all environmental parameters in real time through an integrated data analysis platform, thereby improving the intelligence level of the fermentation process.

[0025] The present invention provides a method for controlling rapid cold fermentation of organic matter using EM bacteria. It has the following beneficial effects:

[0026] The EM bacteria organic matter rapid cold fermentation control method solves the problems of low microbial activity and slow fermentation speed in the traditional cold fermentation process by selecting EM bacteria with good low temperature resistance and accurately controlling the ambient temperature, humidity, oxygen concentration and light intensity. This method is particularly suitable for low temperature environments, effectively promoting the metabolic activity of EM bacteria, thereby accelerating the degradation rate of organic matter. By accurately controlling the temperature and humidity, the optimal growth environment of the flora is ensured, avoiding the problem of long fermentation cycle caused by environmental fluctuations in traditional cold fermentation methods. The fermentation cycle has been significantly shortened, and the activity of microorganisms during cold fermentation is maintained at a high level, greatly improving resource utilization efficiency and production benefits.

[0027] Another significant advantage of the present invention is its efficient environmental control system, including an intelligent temperature control system, a humidity control system, and an oxygen concentration control system.

In addition, the system can monitor and adjust the temperature, humidity, and oxygen concentration in real time through an integrated data analysis platform, thereby improving the intelligence level of the fermentation process.
