[0034] Please see Figure 1-5 This embodiment provides a device for preparing solid-state fermentation strains of Codonopsis pilosula, which solves the technical problems of difficult material processing, high contamination rate and large waste of resources in the solid-state fermentation of Codonopsis pilosula. It has the technical effects of strong process stability, energy saving and environmental protection and wide adaptability.

[0035] Specifically, this embodiment provides a solid-state fermentation strain preparation device for Codonopsis pilosula rootlets, including a fermentation chamber 1, a flexible stirring device 2, a monitoring module 3, a sterilization module 4, a tail gas recovery unit 5, and a control unit 6. The fermentation chamber 1 is provided with a sealing cover 11 at the top and a detachable material tray 12 at the bottom. A heating layer 13 and a humidity spray pipe 14 are fixed to the inner wall of the fermentation chamber 1. The flexible stirring device 2 includes a drive mechanism 21 and a flexible stirring assembly 22, which are connected in a transmission manner. The monitoring module 3 is used to monitor the working environment inside the fermentation chamber 1. The sterilization device includes an electric field generator 41 and an ozone spray pipe 42. The electric field generator 41 is located at the bottom of the sealing cover 11, and the ozone spray pipe 42 is arranged around the inner wall of the fermentation chamber 1. The tail gas recovery unit 5 is connected to the fermentation chamber 1. The control unit 6 is electrically connected to the heating layer 13, the humidity spray pipe 14, the drive mechanism 21, the monitoring module 3, and the sterilization module 4.

[0036] In this embodiment, the fermentation chamber 1 is made of stainless steel, which has good corrosion resistance and sealing properties. A tightly closable sealing cover 11 is installed on its top to ensure an anaerobic or low-oxygen environment during fermentation. A detachable material tray 12 is designed at the bottom of the fermentation chamber 1 for easy removal and handling of materials after fermentation. The detachable material tray 12 is also made of stainless steel, making it easy to clean and disinfect. A heating layer 13 is fixedly installed on the inner wall of the fermentation chamber 1 to regulate the temperature inside the chamber and ensure that the fermentation process takes place at the optimal temperature. Simultaneously, humidity spray pipes 14 are arranged on the inner wall to maintain the required humidity conditions by precisely controlling the amount of water sprayed. The drive mechanism 21 is located outside the fermentation chamber 1 and is driven by a motor. It is connected to the internal flexible stirring component 22 through a shaft penetrating the sealing cover 11. The flexible stirring component 22 is made of high-strength, corrosion-resistant silicone material, which can uniformly mix the fermentation materials without damaging them. Monitoring modules 3 are installed at different locations inside the fermentation chamber 1 to monitor and record the environmental conditions inside the chamber in real time. An electric field generator 41 is installed at the bottom of the sealing cover 11. It generates a high-voltage electric field to ionize and sterilize the air entering the fermentation chamber 1, while simultaneously reducing static electricity buildup. Ozone injection pipes 42 are evenly distributed along the inner wall of the fermentation chamber 1. Through commands from the control unit 6, they release an appropriate amount of ozone to further kill microorganisms inside the chamber and on the surface of the materials, ensuring a sterile fermentation environment. The exhaust gas recovery unit 5, connected to the top of the fermentation chamber 1, collects the gases generated during fermentation, filters them, and then discharges or recycles them, reducing environmental pollution. The control unit 6 uses a PLC (Programmable Logic Controller) as its core and integrates a touchscreen interface. Users can set fermentation parameters (such as temperature, humidity, stirring speed, sterilization intensity, etc.) through the interface, and the system automatically adjusts the operation of each functional module according to the preset program. Data is transmitted wirelessly to the control unit 6, providing precise data for automated control.

[0037] In this embodiment, the pre-treated ginseng rootlets are evenly spread on a material tray, the sealing cover 11 is closed, and the control unit 6 activates the electric field generator 41 and ozone injection pipe 42 to perform preliminary sterilization treatment in the fermentation chamber 1 to ensure a sterile environment. According to preset parameters, the heating layer 13 and humidity spray pipe 14 start working and are adjusted to the optimal fermentation conditions. The drive mechanism 21 is activated, driving the flexible stirring component 22 to mix the materials and ensure uniform fermentation. At the same time, the monitoring module 3 continuously monitors the environmental conditions and automatically adjusts them by the control unit 6 when necessary. The gases generated during fermentation are collected and treated by the exhaust gas recovery unit 5. After the predetermined fermentation time is reached, the control unit 6 stops all operations, opens the sealing cover 11, and removes the material tray for further processing.

[0038] Furthermore, the flexible stirring assembly 22 includes a stirring shaft 221, stirring paddles, and an ultrasonic oscillator 223. The stirring shaft 221 is connected to the drive mechanism 21 via a coupling. Multiple sets of stirring paddles are provided, and multiple sets of stirring paddles 222 are fixedly connected to the outer surface of the stirring shaft 221. The ultrasonic oscillator 223 is fixed to the end of the multiple sets of stirring paddles 222, and the ultrasonic oscillator 223 is electrically connected to the control unit 6.

[0039] In this embodiment, the stirring shaft 221, as the core component of the flexible stirring assembly 22, is tightly connected to the external drive mechanism 21 via a coupling to ensure the stability and efficiency of power transmission. The stirring shaft 221 is made of high-strength, corrosion-resistant alloy material to adapt to various environments during the fermentation process. Multiple sets of stirring blades are evenly distributed on the outer surface of the stirring shaft 221. These blades employ a specially designed blade shape to improve stirring efficiency and the uniformity of material mixing. Each set of stirring blades is firmly fixed to the stirring shaft 221 by high-strength bolts or welding to ensure it will not fall off or loosen during stirring. An ultrasonic oscillator 223 is fixed to the end of each set of stirring blades. These ultrasonic oscillators 223 are connected to the control unit 6 via wires and are precisely controlled by the control unit 6 according to a preset program. The working principle of the ultrasonic oscillator 223 is to utilize the ultrasonic energy generated by high-frequency vibration to stir and break up the material at a microscopic level, thereby further improving fermentation efficiency and product quality.

[0040] In this embodiment, the drive mechanism 21 is activated, driving the stirring shaft 221 and the stirring paddle to mix the materials. Simultaneously, the control unit 6 activates the ultrasonic oscillator 223 according to a preset program, generating high-frequency vibrations to microscopically stir and break down the materials. The addition of ultrasound not only improves the uniformity of material mixing but also helps to break down cell walls in the materials, releasing more nutrients and promoting the growth and metabolism of fermentation strains.

[0041] Furthermore, the surface of the stirring paddle 222 is provided with threads, and a heating wire is provided inside the stirring paddle 222.

[0042] In this embodiment, the threaded structure more effectively grips and mixes the material, especially when the material is viscous or difficult to mix, significantly improving the mixing effect. Each set of stirring paddles 222 is equipped with heating wires. These heating wires are electrically connected to the control unit 6, which precisely controls them according to a preset program. The function of the heating wires is to provide additional heat to the material during mixing, especially in the early stages of fermentation when the material temperature needs to be rapidly raised to the optimal fermentation temperature. Furthermore, during fermentation, the heating wires can also locally heat the material as needed to promote uniform growth and metabolism of the fermentation strains.

[0043] In this embodiment, the drive mechanism 21 activates the stirring shaft 221 and the stirring paddle 222 to mix the materials. The threaded structure of the stirring paddle 222 can more effectively grasp and stir the materials, ensuring uniform mixing. Simultaneously, the control unit 6 activates the heating wire according to a preset program to provide additional heat to the materials. The heating wire works in conjunction with the heating layer 13 within the fermentation chamber 1 to ensure that the materials ferment at the optimal temperature.

[0044] Furthermore, in some embodiments, the monitoring module 3 includes a spectral sensor 31, a temperature sensor 32, a humidity sensor 33, and an oxygen concentration monitor 34. The spectral sensor 31 is disposed on the top of the removable material tray 12 and is used to monitor the active ingredients in the solid-state fermentation process of Codonopsis pilosula. The temperature sensor 32 is disposed on the inner wall of the fermentation chamber 1 and is used to monitor the temperature inside the fermentation chamber 1. The humidity sensor 33 is disposed on the inner wall of the fermentation chamber 1 and is used to monitor the humidity inside the fermentation chamber 1. The oxygen concentration monitor 34 is disposed on the inner wall of the fermentation chamber 1 and is used to monitor the oxygen concentration inside the fermentation chamber 1.

[0045] In this embodiment, a spectral sensor 31 is added to the top of the detachable material tray 12. The spectral sensor 31 can utilize the spectral information generated by the interaction of different wavelengths of light with the material to monitor the changes in active ingredients during the solid-state fermentation of *Codonopsis pilosula* rootlets in real time. This non-destructive monitoring method can reflect the content and changing trends of key active ingredients (such as polysaccharides and saponins) in the material in real time, providing an important basis for optimizing the fermentation process and improving product quality. A temperature sensor 32 is installed on the inner wall of the fermentation chamber 1 to monitor the temperature inside the chamber in real time. Accurate temperature measurement ensures that the fermentation process is carried out within the optimal temperature range, avoiding adverse effects of excessively high or low temperatures on the fermentation strains. A humidity sensor 33 is also installed on the inner wall of the fermentation chamber 1 to monitor the humidity inside the chamber in real time. An oxygen concentration monitor 34 is also installed on the inner wall of the fermentation chamber 1 to monitor the oxygen concentration inside the chamber in real time. During solid-state fermentation, the supply of oxygen is crucial for the growth and metabolism of the strains. By monitoring oxygen concentration, ventilation strategies can be adjusted in a timely manner to ensure that fermentation strains grow and metabolize in a suitable oxygen environment. Precise control of humidity is crucial for maintaining the activity of fermentation strains and promoting uniform fermentation of materials.

[0046] In this embodiment, during the fermentation process of Codonopsis pilosula rootlets, the spectral sensor 31 continuously monitors the changes in the active ingredients in the material and transmits the data to the control unit 6 in real time. The temperature sensor 32, humidity sensor 33, and oxygen concentration monitor 34 monitor the temperature, humidity, and oxygen concentration in the fermentation chamber 1, respectively, to ensure that the fermentation process is carried out under optimal conditions.

[0047] Furthermore, the exhaust gas recovery unit 5 includes a condenser pipe 51, a storage tank 52, and a vacuum pump 53. The condenser pipe 51 is connected to the top of the fermentation chamber 1; the storage tank 52 is connected to one end of the condenser pipe 51; the vacuum pump 53 is connected to the condenser pipe 51 and is electrically connected to the control unit 6.

[0048] In this embodiment, the condenser 51 is located at the top of the fermentation chamber 1 and is connected to the interior of the fermentation chamber 1. During fermentation, the generated exhaust gas (including water vapor, volatile organic compounds, etc.) is cooled and condensed through the condenser 51. The condenser 51 is designed using a highly efficient heat exchange principle to ensure that water vapor and other condensable components in the exhaust gas can be effectively condensed into liquid. The liquid storage tank 52 is connected to one end of the condenser 51 and is used to collect and store the condensate flowing out of the condenser 51. The design of the liquid storage tank 52 takes into account the need for easy cleaning and maintenance to ensure long-term operational stability and reliability. The vacuum pump 53 is connected to the condenser 51 and is used to provide the necessary negative pressure environment during the condensation process. The vacuum pump 53 can be precisely controlled by the control unit 6 to adjust the pressure inside the condenser 51, thereby optimizing the condensation effect. The operating status of the vacuum pump 53 can be monitored and adjusted in real time through the touch screen interface of the control unit 6.

[0049] In this embodiment, the vacuum pump 53 provides the necessary negative pressure environment during the condensation process. By precisely controlling the vacuum pump 53 through the control unit 6, the pressure inside the condenser tube 51 can be adjusted to optimize the condensation effect. The presence of the negative pressure environment also helps to reduce the escape of volatile organic compounds in the exhaust gas into the air and improve the exhaust gas recovery efficiency.

[0050] Furthermore, an ultraviolet sterilization lamp 111 is installed on the sealed inner wall, and the ultraviolet sterilization lamp 111 is electrically connected to the control unit 6.

[0051] In this embodiment, the sealing cap 11 is used to seal the fermentation chamber 1, preventing external microbial contamination and leakage of the internal fermentation environment. The sealing cap 11 is designed for ease of opening and closing to ensure convenient operation and reliable sealing. An ultraviolet sterilization lamp 111 is disposed on the inner wall of the sealing cap 11 and is electrically connected to the control unit 6. The ultraviolet sterilization lamp 111 emits ultraviolet light of a specific wavelength to sterilize the interior of the fermentation chamber 1. Before or after each opening and closing of the sealing cap 11, the control unit 6 can automatically or manually activate the ultraviolet sterilization lamp 111 to rapidly sterilize the contact surfaces between the sealing cap 11 and the fermentation chamber 1, ensuring a sterile fermentation environment.

[0052] Furthermore, an observation window 15 is provided on the side wall of the fermentation chamber 1, and the inside of the observation window 15 is provided with an anti-fog coating.

[0053] In this embodiment, an observation window 15 is provided on the side wall of the fermentation chamber 1, allowing operators to directly observe the internal conditions of the fermentation chamber 1 during the fermentation process. The observation window 15 is designed with safety and convenience in mind, and is made of high-strength, corrosion-resistant materials to ensure its stability and reliability during use. An anti-fog coating is provided inside the observation window 15. This coating effectively prevents fogging caused by humidity changes during fermentation, thus preventing interference with observation. The anti-fog coating utilizes advanced nanotechnology to form a uniform, transparent film on the surface of the observation window 15, effectively preventing water vapor condensation and maintaining a clear view.

[0054] Furthermore, the control unit 6 integrates a spectral monitoring unit 61, a temperature monitoring unit 62, a humidity monitoring unit 63, an oxygen monitoring unit 64, and a communication unit 65.

The spectral monitoring unit 61 is electrically connected to the spectral sensor 31 and is used to monitor the spectral characteristics of the material in the fermentation chamber 1 in real time. The spectral sensor 31 can capture spectral changes in the material during fermentation, such as color and fluorescence, providing operators with intuitive information about the fermentation status. Through analysis of the spectral data, the spectral monitoring unit 61 can help operators determine the fermentation progress, identify potential problems, and adjust fermentation conditions in a timely manner. The temperature monitoring unit 62 is electrically connected to the temperature sensor 32 and is used to monitor the temperature in the fermentation chamber 1 in real time. The temperature sensor 32 can accurately measure the temperature in the fermentation chamber 1 and transmit the data to the temperature monitoring unit 62 in real time. The temperature monitoring unit 62 automatically adjusts the heating power of the heating layer 13 according to a preset temperature range to maintain the temperature in the fermentation chamber 1 at the optimal fermentation conditions.
