[0002] Multi-strain fermented beverages of traditional Chinese medicine refer to beverages that combine traditional Chinese medicinal materials with various probiotics. Through microbial fermentation technology, the effective components of Chinese medicine are transformed into small molecules that are more easily absorbed by the human body. At the same time, the taste is improved, the efficacy is enhanced, and the toxicity is reduced, forming a new type of beverage that combines the therapeutic effects of Chinese medicine with the health benefits of probiotics. In this context, a corresponding automatic mixing and fermentation system is needed to realize its preparation.

[0003] Referring to patent application CN221759837U, a mixed fermentation device for Polygonatum-based beverages is disclosed. This device features two stirring rods, which can be cleaned after use. Simply start motor three to lower the fermentation tank and separate it from the stirring rods, then start motor one to change the position of the two stirring rods, allowing for another fermentation cycle. Simultaneously, the stirring rods can be cleaned, significantly shortening the interval between fermentations and improving overall fermentation efficiency. Furthermore, the device utilizes inserts and slots, and the locking rod and locking slot allow for easy removal of the stirring rods by simply rotating a two-way screw, simplifying operation and greatly facilitating subsequent cleaning.

[0004] A comprehensive analysis of the above-mentioned patents reveals the following shortcomings: Existing automated mixed fermentation systems and processes for preparing multi-strain fermented beverages of traditional Chinese medicine suffer from significant fluctuations in dissolved oxygen and pH levels during fermentation due to microbial metabolism. These fluctuations affect the normal metabolism of microorganisms and the quality of fermentation products, making stable liquid fermentation difficult. Furthermore, the systems lack the ability to automatically and promptly control dissolved oxygen and pH levels within the required range during mixed fermentation. Therefore, it is necessary to provide an automated mixed fermentation system and process for preparing multi-strain fermented beverages of traditional Chinese medicine to address these technical problems.

[0016] Beneficial effects This invention provides an automated mixing and fermentation system and process for preparing multi-strain fermented beverages of traditional Chinese medicine. Compared with existing technologies, it has the following advantages: 1. An automated mixing and fermentation system and process for preparing multi-strain fermented beverages of traditional Chinese medicine, comprising a mixing frame mechanism, a driving mechanism, a cam frame mechanism, a gas extraction mechanism, and a solution extraction mechanism, wherein the driving mechanism not only drives the mixing frame mechanism to rotate, stirring and mixing the liquid traditional Chinese medicine and various probiotics in the fermentation tank, but also drives the two cam frame mechanisms to rotate, thereby driving the gas extraction mechanism and the solution extraction mechanism to work. The gas extraction mechanism draws external gas into the fermentation tank to control the dissolved oxygen content in the material and meet the dissolved oxygen requirements during the liquid fermentation process. The solution extraction mechanism draws external pH adjustment solution into the fermentation tank to adjust the pH value in the material and maintain it within the required range, effectively preventing large fluctuations in dissolved oxygen and pH value caused by microbial metabolism during fermentation and ensuring the stable progress of liquid fermentation.

[0017] 2. An automated mixing and fermentation system and process for preparing multi-strain fermented beverages of traditional Chinese medicine, which, through the cooperation of hollow outer rods, auger blades, hollow support rods, spiral blades, hollow inner rods and aeration rings, can fully stir and mix liquid traditional Chinese medicine and probiotics at different depths in the fermentation tank. At the same time, the gas enters the aeration ring through the hollow inner rods and can be evenly dispersed into the material, effectively controlling the dissolved oxygen content of the material in the fermentation tank. The spray nozzles on the hollow support rods also provide convenience for liquid phase control, ensuring the stability and efficiency of the fermentation process.

[0018] 3. An automatic mixing fermentation system and process for preparing multi-strain fermented beverages of traditional Chinese medicine, through the cooperation of a worm gear, a small toothed ring, a servo motor, an annular electromagnet, a cam, a large toothed ring, and a first spring, driven by a servo motor, utilizes the meshing of the worm gear and worm wheel to drive the auger blades, hollow support rod, and spiral blades to rotate, rapidly promoting thorough mixing of materials at different depths within the fermentation tank. When the annular electromagnet is not energized, the small toothed ring meshes with the large toothed ring, and the cam rotates with the worm gear, simultaneously driving the gas extraction mechanism and the solution extraction mechanism. At this time, it is in the working state of inputting gas and acid-base adjustment solution into the fermentation tank. When the annular electromagnet is energized, it attracts the large toothed ring, causing the small toothed ring to separate from the large toothed ring. The cam does not rotate with the worm gear, and the gas extraction mechanism and the solution extraction mechanism do not work. At this time, it is in the working state of no longer inputting gas and acid-base adjustment solution into the fermentation tank. It can realize the switching of multiple working states and is flexible and convenient to use.

[0019] 4. An automated mixing fermentation system and process for preparing multi-strain fermented beverages of traditional Chinese medicine, through the cooperation of a cylinder, piston, piston rod, second spring, solution extraction mechanism, and cam, the piston rod reciprocates back and forth under the elastic action of the second spring as the cam rotates, and the piston reciprocates accordingly. During this process, external gas is drawn into the cylinder through a long suction pipe, then discharged into the gas collection box through a discharge bend pipe, and finally discharged into the material in the fermentation tank through the hollow inner rod and aeration ring, controlling the dissolved oxygen content in the material. At the same time, the cam can also drive the solution extraction mechanism to draw external acid-base adjusting solution into the fermentation tank to adjust the pH value of the material. There is no need to set up a separate pump for gas extraction or acid-base adjusting solution extraction, reducing the cost of the device.

Both ends of the worm 42 rotate through the side wall of the support frame 41 and are rotatably connected to the side wall of the corresponding side plate 44. Two small toothed rings 43 are fixedly sleeved on the outside of the worm 42. The two small toothed rings 43 are located on the left and right sides of the outside of the support frame 41, respectively. A servo motor 45 is fixedly installed on the left side of the left side plate 44. The output shaft of the servo motor 45 rotates through the side plate 44 and is fixedly connected to the left end of the worm 42. Side plates 44 are fixedly installed on both sides of the support frame 41 and behind the worm 42. The system includes an annular electromagnet 46 and two cam frame mechanisms 5, each including a second side plate 51. The bottom of the second side plate 51 is fixedly connected to the top of the fermentation tank 1. A short shaft 52 is rotatably mounted between the second side plate 51 and the side wall of the support frame 41. A cam 53 is fixedly sleeved on the outside of the short shaft 52. One end of the short shaft 52 passes through the center of the adjacent annular electromagnet 46. A limiting groove 54 is formed on the side wall of the short shaft 52. A large toothed ring 55 is sleeved on the outside of the short shaft 52. A protrusion is fixedly mounted on the inner wall of the large toothed ring 55. The protrusion is slidably mounted in the limiting groove 54. A first spring 56 is mounted in the limiting groove 54.

The gas extraction mechanism 6 includes a cylinder 61.The bottom of the cylinder 61 is fixedly connected to the top of the fermentation tank 1 by two support plates. A piston 62 is slidably disposed between the inner walls of the cylinder 61. A piston rod 63 is fixedly disposed at the front end of the piston 62.

The discharge bend 65 in the solution extraction mechanism 7 is fixedly connected to the liquid collection box 36.

[0027] Through the coordinated operation of the hollow outer rod 31, auger blades 32, hollow support rod 33, spiral blades 34, hollow inner rod 37, and aeration ring 38, the liquid Chinese medicine and probiotics at different depths within the fermentation tank 1 can be thoroughly stirred and mixed. Simultaneously, gas entering the aeration ring 38 through the hollow inner rod 37 is evenly dispersed into the material, effectively controlling the dissolved oxygen level within the fermentation tank 1. Furthermore, the spray nozzles on the hollow support rod 33 facilitate liquid phase control, ensuring the stability and efficiency of the fermentation process. The worm gear 42, small toothed ring 43, servo motor 45, annular electromagnet 46, cam 53, and large toothed ring further enhance the fermentation process. The interaction between 55 and the first spring 56, driven by a servo motor 45, and utilizing the meshing of the worm gear 42 and worm wheel 35, drives the auger blades 32, hollow support rod 33, and spiral blades 34 to rotate, rapidly promoting thorough mixing of materials at different depths within the fermentation tank 1. When the annular electromagnet 46 is not energized, the small toothed ring 43 meshes with the large toothed ring 55, and the cam 53 rotates with the worm gear 42, simultaneously driving the gas extraction mechanism 6 and the solution extraction mechanism 7 to work. At this time, it is in the working state of inputting gas and acid-base adjustment liquid into the fermentation tank 1. When the annular electromagnet 46 is de-energized, the small toothed ring 43 meshes with the large toothed ring 55, and the cam 53 rotates with the worm gear 42, simultaneously driving the gas extraction mechanism 6 and the solution extraction mechanism 7 to work. When the internal 46 is energized, it attracts the large toothed ring 55, causing the small toothed ring 43 to separate from the large toothed ring 55. The cam 53 does not rotate with the worm gear 42, and the gas extraction mechanism 6 and solution extraction mechanism 7 cease operation. At this point, the fermentation tank 1 is no longer being fed gas or acid / alkali adjusting solution. This allows for switching between multiple operating states, making it flexible and convenient to use. Through the cooperation between the cylinder 61, piston 62, piston rod 63, second spring 64, solution extraction mechanism 7, and cam 53, the piston rotates with the cam 53, and under the elastic action of the second spring 64, the piston... The rod 63 reciprocates back and forth, and the piston 62 reciprocates accordingly. During this process, external gas is drawn into the cylinder 61 through the suction tube 66, and then discharged into the gas collection box 39 through the discharge bend 65. After passing through the hollow inner rod 37, it is finally discharged into the material in the fermentation tank 1 through the aeration ring 38, controlling the dissolved oxygen content in the material. At the same time, the cam 53 can also drive the solution pumping mechanism 7 to work, drawing external acid-base adjustment solution into the fermentation tank 1 to adjust the pH value in the material. There is no need to set up a separate pump for pumping out gas or acid-base adjustment solution, reducing the cost of the device.

[0028] This invention also provides an automated mixing and fermentation process for preparing multi-strain fermented beverages of traditional Chinese medicine. The process employs an automated mixing and fermentation system for preparing multi-strain fermented beverages of traditional Chinese medicine, and includes the following steps: Step 1: Liquid Chinese medicine and various probiotics are fed into fermentation tank 1 through a feeding pipe. Then, the driving mechanism 4 drives the mixing frame mechanism 3 to rotate. During the process, the servo motor 45 works and drives the worm gear 42 to rotate. By meshing the worm gear 42 with the worm wheel 35, the hollow outer rod 31 can be driven to rotate. The auger blades 32, hollow support rods 33 and spiral blades 34 rotate accordingly, stirring and mixing the liquid Chinese medicine and various probiotics in fermentation tank 1 to carry out liquid fermentation. Step 2: Simultaneously, the annular electromagnet 46 is not energized, the small toothed ring 43 meshes with the large toothed ring 55, and the cam 53 rotates with the worm gear 42, which simultaneously drives the gas extraction mechanism 6 and the solution extraction mechanism 7 to work. The gas extraction mechanism 6 works to draw external gas into the fermentation tank 1, controlling the dissolved oxygen content in the material in the fermentation tank 1 to meet the dissolved oxygen requirements in the liquid fermentation process. During the process, as the cam 53 rotates, under the elastic action of the second spring 64, it can push the piston rod 63 to move back and forth, and the piston 62 moves back and forth accordingly. During this process, external gas can be drawn into the cylinder 61 through the long suction pipe 66, and then discharged into the gas collection box 39 through the discharge bend pipe 65. After that, it passes through the hollow inner rod 37 and finally through the aeration ring 38 into the material in the fermentation tank 1 to control the dissolved oxygen content in the material. The aeration ring 38 is a prior art known to those skilled in the art. Step 3: Since the solution extraction mechanism 7 and the gas extraction mechanism 6 are identical in structure except for the discharge bend 65, and are symmetrical, the rotation of the cam 53 can drive the solution extraction mechanism 7 to work, drawing the external acid-base regulating solution into the fermentation tank 1 to adjust the pH value of the material. During the process, since the discharge bend 65 in the solution extraction mechanism 7 is fixedly connected to the collection box 36, the solution extraction mechanism 7 draws the external acid-base regulating solution into the collection box 36, then flows into the hollow outer rod 31, into each hollow support rod 33, and finally sprays it out through the spray nozzle on the hollow support rod 33. Under the stirring action of the auger blade 32 and the spiral blade 34, the acid-base regulating solution is fully mixed with the material in the fermentation tank 1, so that the pH value of the material is maintained within the required range, preventing large changes in the pH value of the material due to microbial metabolism during liquid fermentation, ensuring stable fermentation. After the mixture is fully fermented, it is discharged through the discharge pipe, and then further processing is carried out to obtain the fermented beverage.
