[0002] In traditional Chinese medicine, Polygonatum sibiricum and Cistanche deserticola are widely used in the treatment and regulation of various ailments as medicinal herbs with significant medicinal value. Polygonatum sibiricum has the effects of tonifying qi and nourishing yin, strengthening the spleen, moistening the lungs, and benefiting the kidneys, while Cistanche deserticola is known for tonifying kidney yang, replenishing essence and blood, and moistening the intestines to relieve constipation. The two are often used together, showing unique advantages in improving reproductive system function and enhancing bodily vitality. However, traditional methods of utilizing Polygonatum sibiricum and Cistanche deserticola mainly involve direct medicinal application or simple processing, which limits the release and absorption efficiency of their active ingredients and makes it difficult to fully realize their potential efficacy. Furthermore, environmental control during fermentation is crucial to the fermentation effect. Existing fermentation equipment has shortcomings in promoting uniform mixing of the fermentation broth and ensuring consistent fermentation temperature, easily leading to incomplete fermentation, uneven quality, and other problems, affecting the overall quality and efficiency of the fermentation product.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Reference Figures 1-8 A fermentation device for fermentation products of Polygonatum sibiricum and Cistanche deserticola includes a shell 1. The shell 1 is provided with an installation cavity 11 and a culture cavity 12. A sealing door 5 is installed on the front side of the culture cavity 12. The sealing door 5 is made of transparent material and has a sealing strip at the edge to ensure the airtightness of the culture cavity 12 while allowing observation of the internal fermentation. The system also includes a placement mechanism, which includes a support plate 19 disposed inside the culture chamber 12. A culture box 14 is placed on the upper end of the support plate 19. A rectangular insert 35 is fixedly connected to the upper end of the support plate 19. A rectangular slot 34 that mates with the rectangular insert 35 is provided at the lower end of the culture box 14. A rubber layer is provided on the outer side of the rectangular insert 35 to ensure a tight seal. An annular flow distribution cavity 33 is provided inside the culture box 14. The annular flow distribution cavity 33 is connected to the inner bottom of the culture box 14 through multiple flow distribution holes. The system also includes a gas circulation mechanism, which is installed inside the mounting cavity 11 and works in conjunction with the placement mechanism to inject gas into the annular diversion cavity 33. The gas then rises as bubbles at multiple diversion holes 32, promoting fermentation. The gas circulation mechanism includes a dual-axis motor 25 installed at the top of the mounting cavity 11. The lower output shaft of the dual-axis motor 25 is fixedly connected to a drive disk 26. A piston cylinder 27 is installed at the bottom of the mounting cavity 11. A piston plate 28 that can slide left and right is provided inside the piston cylinder 27. The left side of the piston plate 28 is rotatably connected to the lower eccentric part of the drive disk 26 via a connecting rod 29. A columnar cavity 36 is provided inside the culture box 14. The columnar cavity 36 is connected to the annular diversion cavity 33 through multiple one-way ports. A connecting column 24 is fixedly connected to the lower end of the support plate 19. A slider 21 is fixedly connected to the lower end of the connecting column 24. An L-shaped connecting channel 4 is provided in the rectangular insert 35, the support plate 19, the connecting column 24, and the slider 21. Furthermore, the bottom of the cylindrical cavity 36 is provided with a mating interface that mates with the L-shaped connecting channel 4. The other end of the L-shaped connecting channel 4 is connected to the right side space of the piston cylinder 27 through the first one-way tube 18. The right side space of the piston cylinder 27 is connected to the top space of the culture chamber 12 through the second one-way tube 30. A one-way valve is installed inside the one-way port, allowing the cylindrical cavity 36 to enter the annular diversion cavity 33 in one direction. A one-way valve is installed inside the first one-way tube 18, allowing the piston cylinder 27 to enter the L-shaped connecting channel 4 in one direction. A one-way valve is installed inside the second one-way tube 30, allowing the top space of the culture chamber 12 to enter the piston cylinder 27 in one direction. In practical use, the dual-axis motor 25 starts, and the drive disc 26 rotates, causing the piston plate 28 to move left and right inside the piston cylinder 27. When the piston plate 28 moves to the right, the pressure in the space on the right side of the piston cylinder 27 increases, and the gas enters the L-shaped connecting channel 4 through the first one-way pipe 18, then enters the columnar cavity 36 through the interface, and then enters the annular diversion cavity 33 through the one-way port. Finally, it floats to the culture medium in the form of bubbles from multiple diversion holes. When the piston plate 28 moves to the left, the pressure in the space on the right side of the piston cylinder 27 decreases, and the gas in the top space of the culture chamber 12 enters the space on the right side of the piston cylinder 27 through the second one-way pipe 30, completing the gas circulation. Through the gas circulation mechanism, gas can be continuously injected into the culture medium. The gas floats to the surface in the form of bubbles, which can promote liquid flow, ensure the uniformity of fermentation concentration, avoid the occurrence of pile heat, and improve the fermentation effect.

[0022] The system also includes a shaking mechanism, which comprises a groove 20 located at the bottom of the culture chamber 12. A slider 21 is slidably connected inside the groove 20. Multiple guide rods 22 are fixedly connected between the left and right sides of the groove 20, and all guide rods 22 pass through the slider 21 and are slidably connected. The right side of the slider 21 is elastically connected to the inner wall of the groove 20 by multiple springs 23. A gearbox 17 is installed at the bottom of the culture chamber 12. A cam 16 is fixedly connected to the output end of the gearbox 17. The cam 16 abuts against the outer side of the support plate 19. The input shaft of the gearbox 17 is fixedly connected to the upper output shaft of the dual-axis motor 25. When the shaking mechanism is running, the cam 16 rotates, and the protruding part of the cam 16 continuously squeezes the support plate 19. Under the action of the springs 23, the support plate 19 causes the culture box 14 to shake. This shaking can promote liquid flow and use the inertia of the liquid to deform the floating bubbles, increase their floating resistance, reduce their floating speed, and thus increase the possibility of them bursting in the liquid, thereby improving the actual effect of bubble mixing.

[0023] It also includes a nitrogen injection mechanism, which is used to remove oxygen from the culture chamber 12 after a period of aerobic fermentation. The nitrogen injection mechanism includes a nitrogen inlet pipe 15, one end of which extends into the piston cylinder 27. The top of the culture chamber 12 is connected to the outside through a vent hole 31. Solenoid valves are installed in both the vent hole 31 and the nitrogen inlet pipe 15. After fermentation for a period of time (Lactobacillus rhamnosus is a facultative anaerobic bacterium; short-term micro-oxygenation is used in the early stage of fermentation to promote rapid proliferation of the strain, and then the anaerobic conditions are switched to synthesize the product), the solenoid valve inside the nitrogen inlet pipe 15 is opened, and the nitrogen enters the piston cylinder 27 through the nitrogen inlet pipe 15, then enters the L-shaped connecting channel 4 through the first one-way pipe 18, then enters the columnar cavity 36 through the interface, and then enters the annular diversion cavity 33 through the one-way port. Finally, it floats to the culture medium in the form of bubbles from multiple diversion holes and finally enters the culture chamber 12. The oxygen in the culture chamber 12 and the oxygen in the fermentation broth are finally discharged through the vent hole 31 to achieve rapid removal of oxygen.

[0024] It also includes an adjustable heat dissipation mechanism, which can dissipate heat when the fermentation temperature inside the culture chamber 12 rises, so as to avoid the fermentation temperature being too high and affecting the fermentation. The adjustable heat dissipation mechanism includes rectangular grooves 10 symmetrically opened on both sides of the shell 1. The inner walls of the two rectangular grooves 10 are each embedded with a temperature guiding plate extending into the culture chamber 12. Multiple heat dissipation fins 13 are installed on the temperature guiding plate. A U-shaped frame 6 is fixedly connected to the upper end of the shell 1. A telescopic cylinder 7 is installed at the lower end of the horizontal part of the U-shaped frame 6. A horizontal lifting plate 8 is fixedly connected to the telescopic end of the telescopic cylinder 7. Vertical baffles 9 for blocking the heat dissipation fins 13 are fixedly connected to both sides of the horizontal lifting plate 8. When the temperature inside the culture chamber 12 is normal, the telescopic cylinder 7 retracts, and the vertical baffle 9 blocks the heat sink 13 from dissipating heat. When the temperature inside the culture chamber 12 is too high (this fermentation is a heat dissipation reaction), the telescopic cylinder 7 extends, and the vertical baffle 9 moves upward, partially or completely blocking the heat sink 13 to achieve heat dissipation.

[0025] The controller 2 is installed on the front side of the shell 1, and the display panel 3 is installed on the front side of the shell 1. The temperature sensor and the electric heater are installed inside the piston cylinder 27. The temperature sensor is electrically connected to the display panel 3. With the help of the gas circulation mechanism, the internal temperature can be made more uniform and the monitoring more accurate. In the early stage of fermentation, the electric heater can be started for a period of time. With the help of the gas circulation mechanism, the internal temperature can be quickly raised to about 37 degrees Celsius to ensure the microorganisms.

[0026] In this invention, the sealing door 5 is opened, and the fermentation raw material inoculated with Lactobacillus rhamnosus is placed into the culture box 14. The sealing door is then closed for aerobic fermentation. The dual-shaft motor 25 is started, and the upper output shaft of the dual-shaft motor 25 drives the gearbox 17 to run. The output end of the gearbox 17 drives the cam 16 to rotate. The protruding part of the cam 16 continuously squeezes the support plate 19. Under the action of the spring 23, the support plate 19 drives the culture box 14 to vibrate along the guide rod 22 in the slide 20, promoting liquid flow.

[0027] Simultaneously, the lower output shaft of the dual-axis motor 25 drives the drive disk 26 to rotate. The drive disk 26, through the connecting rod 29, drives the piston plate 28 to move left and right within the piston cylinder 27. When the piston plate 28 moves to the right, the pressure in the space on the right side of the piston cylinder 27 increases. Gas enters the L-shaped connecting channel 4 through the first one-way pipe 18, then enters the columnar cavity 36 through the interface, and then enters the annular diversion cavity 33 through the one-way port. Finally, it floats to the culture medium in the form of bubbles from multiple diversion holes. When the piston plate 28 moves to the left, the pressure in the space on the right side of the piston cylinder 27 decreases. Gas in the top space of the culture chamber 12 enters the space on the right side of the piston cylinder 27 through the second one-way pipe 30, completing the gas circulation. By continuously injecting gas into the culture medium, the rising of bubbles promotes liquid flow, ensures uniform fermentation concentration, avoids localized overheating, and the shaking mechanism further promotes bubble mixing. This stage provides a short-term micro-aerobic environment for Lactobacillus rhamnosus, promoting rapid proliferation of the strain.

[0028] After aerobic fermentation for a period of time, the solenoid valve inside the nitrogen inlet pipe 15 is opened, and the nitrogen enters the piston cylinder 27 through the nitrogen inlet pipe 15, then enters the L-shaped connecting channel 4 through the first one-way pipe 18, then enters the columnar cavity 36 through the interface, and then enters the annular diversion cavity 33 through the one-way port. Finally, it floats to the culture medium in the form of bubbles from multiple diversion holes and finally enters the culture chamber 12. The oxygen in the culture chamber 12 and the oxygen in the fermentation liquid are discharged through the vent hole 31 to achieve rapid oxygen removal. After a period of time, the two solenoid valves are closed.

[0029] During anaerobic fermentation, the dual-shaft motor 25 runs continuously, and the gas circulation mechanism continues to work according to the above principle, continuously injecting nitrogen bubbles into the culture medium to promote liquid flow. Meanwhile, the shaking mechanism continues to run, and the support plate 19 drives the culture box 14 to shake. By utilizing the inertia of the liquid, the floating bubbles are deformed, increasing their floating resistance and reducing their floating speed, thereby increasing the possibility of them bursting in the liquid, improving the actual effect of bubble mixing, and ensuring the smooth progress of anaerobic fermentation.

[0030] The temperature sensor inside the piston cylinder 27 monitors the temperature in real time and transmits the data to the display panel 3 for display.

[0031] In the early stages of fermentation, the electric heater can be started for a period of time, in conjunction with the gas circulation mechanism, to rapidly raise the internal temperature to about 37 degrees Celsius, ensuring the activity of microorganisms. When the temperature inside the culture chamber 12 is normal, the telescopic cylinder 7 is in a contracted state, and the vertical baffle 9 blocks the heat sink 13 from dissipating heat. When the temperature inside the culture chamber 12 is too high (this fermentation is a heat dissipation reaction), the telescopic cylinder 7 extends, the vertical baffle 9 moves upward, partially or completely exposing the heat sink 13, and the heat inside the culture chamber 12 is conducted to the heat sink 13 for heat dissipation through the temperature conduction plate, thereby regulating the temperature inside the culture chamber 12. In conjunction with the gas circulation mechanism, the internal temperature is made more uniform.

[0032] This invention also discloses a fermentation method for the fermentation product of Polygonatum sibiricum and Cistanche deserticola, using the above-mentioned fermentation apparatus, including the following steps: Step 1: Select high-quality Polygonatum rhizomes with complete growth cycle, plump appearance and no pests or diseases, and Cistanche deserticola fleshy stems with firm texture and uniform color as basic raw materials; Step 2: Process and dry the selected raw materials; Step 3: Crush the dried raw material, add sterile water at a material-to-liquid ratio of 1:10, place it in a heating reflux device, and extract the processed raw material using the heating reflux method; Step 4: After mixing the extracts of Polygonatum sibiricum and Cistanche deserticola in a ratio of 2:1 to 1:2 and sterilizing them at high temperature, they are inoculated with Lactobacillus rhamnosus to obtain fermentation raw materials; Step 5: Place the fermentation raw materials into the fermentation device and ferment the bacterial solution for 12-30 hours. The resulting fermentation liquid is the fermentation product of Polygonatum sibiricum and Cistanche deserticola.
