Description

Technical Field

[0001] The invention relates to the technical field of fermentation engineering, and in particular to an intelligent fermentation system. Background Art

[0002] Traditional Chinese medicine fermentation technology is a modern Chinese medicine processing technology that uses the growth and metabolic activities of microorganisms to produce various useful substances. It is developed on the basis of traditional Chinese medicine fermentation processing methods, combined with the cutting-edge achievements of modern microbiology, fermentation engineering technology, and drug analysis technology. The commonly used fermentation method is liquid fermentation, using Chinese herbal medicine extracts, powders, etc. and liquid culture media as nutrient matrices, and using a single strain or mixed strains for fermentation. Liquid fermentation has the advantages of high degree of automation, low production cost, good product stability, and high material transfer rate, and is very suitable for industrial production.

[0003] The current Chinese medicine fermentation process requires the use of fermentation tanks and other devices for fermentation. Since fermentation requires a suitable temperature, temperature control for fermentation is crucial. The current fermentation device generally has two heating methods. One is to use the jacket of the fermentation tank for heating. By setting a heating wire in the jacket, the mixed liquid in the fermentation tank is heated to maintain the fermentation temperature. This method is also the most commonly used method at present. However, this heating method requires the liquid culture medium to be added to the tank before it can be slowly heated, which affects the heating efficiency. Once the heating is completed, as the fermentation temperature increases, when it is necessary to cool down to maintain a suitable fermentation temperature, it is difficult to quickly cool down, which is inconvenient to use. The second is to use high-temperature steam. By setting a steam pipe in the fermentation tank, high-temperature steam is injected into the fermentation tank to achieve rapid heating, and the steam can be quickly turned off for cooling. However, when this method is actually used, it will cause high-temperature steam to enter the liquid culture medium. The water formed after the high-temperature steam is liquefied will dilute the fermented liquid, thereby affecting the fermentation effect. At the same time, the existing fermentation device needs to add a stirring mechanism because the fermentation liquid needs to be stirred and mixed. Generally, the driving motor is arranged outside the fermentation device, and the stirring blades are arranged inside the fermentation device, so as to achieve stirring of the fermentation liquid. However, this method requires adding a lot of structures, which is not only costly, but also makes it inconvenient to clean the inside of the fermentation device. Summary of the invention

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0020] like Figure 1-Figure 4 As shown, the intelligent fermentation system includes a fermentation tank 1, a bacterial liquid constant temperature input device 2 and a fermentation liquid temperature control device 3.

[0021] The fermentation tank 1 is the core part of the system, which is used to contain Chinese medicine raw materials and bacterial liquid for fermentation. The fermentation tank 1 has multiple interfaces, including bacterial liquid input port 11, Chinese medicine raw material input port 12, fermentation liquid output port 13 and fermentation liquid input port 14. An observation window 16 is provided on the outer wall for observing the fermentation process; a drain port 17 is provided at the lower end for discharging the liquid after fermentation or for cleaning. The heating interlayer is used to heat the tank body 1 to maintain the temperature of the fermentation liquid.

[0022] like Figure 1 As shown, the bacterial liquid constant temperature input device 2 includes a first tank body 21, a bacterial liquid input end 22, a bacterial liquid output end 23 and a first temperature control component.

[0023] The bacterial seed liquid input end 22 is used to receive external bacterial seed liquid, and the bacterial seed liquid output end 23 is connected to the bacterial seed liquid input port 11 of the fermentation tank 1 .

[0024] The first temperature control component is disposed in the first tank 21 and connected between the bacterial liquid input end 22 and the bacterial liquid output end 23. Specifically, Figure 3 As shown, the first temperature control component includes a bacterial liquid storage tank 241 , a heating element 242 (a PTC heating tube is used in this embodiment), a first temperature sensor 243 , a first electric valve 244 and a second electric valve 245 .

[0025] The bacterial liquid storage tank 241 is connected to the bacterial liquid input end 22 for temporarily storing the input bacterial liquid. The heating element 242 is connected to the bacterial liquid storage tank 241 through a pipeline for heating the bacterial liquid. The first temperature sensor 243 is arranged in the pipeline for real-time monitoring of the temperature of the bacterial liquid. The first electric valve 244 is connected to the pipeline between the first temperature sensor 243 and the bacterial liquid output end 23. When the bacterial liquid temperature detected by the first temperature sensor 243 reaches the preset temperature, the first electric valve 244 opens to allow the bacterial liquid to flow out to the fermentation tank 1. The second electric valve 245 is connected to the pipeline between the first temperature sensor 243 and the first electric valve 244, and is connected to the bacterial liquid storage tank 241. When the bacterial liquid temperature does not reach the preset temperature, the first electric valve 244 is closed, and the second electric valve 245 is opened to return the bacterial liquid to the storage tank for further heating.

[0026] Figure 1 and Figure 4 As shown, the fermentation liquid temperature control device 3 includes a second tank body 31, a fermentation liquid input end 32, a fermentation liquid output end 33 and a second temperature control component.

[0027] The fermentation liquid input end 32 is connected to the fermentation liquid output end 13 of the fermentation tank 1 , and the fermentation liquid output end 33 is connected to the fermentation liquid input end 14 (as a circulation reflux port) of the fermentation tank 1 , forming a closed-loop control system.

[0028] The second temperature control assembly is disposed in the second tank 31 and connected between the fermentation liquid input end 32 and the fermentation liquid output end 33. Specifically, the second temperature control assembly includes a second temperature sensor 341, a water pump 342, a cooling element 343 and a third electric valve 344.

[0029] The second temperature sensor 341 is used to monitor the temperature of the fermentation liquid in real time. The water pump 342 is connected to the fermentation liquid input end 32 through a pipeline to drive the fermentation liquid to circulate between the fermentation tank 1 and the temperature control device. The cooling element 343 is connected to the water pump 342 to cool the circulating fermentation liquid. In this embodiment, the cooling element adopts a cooling coil. The third electric valve 344 is arranged on the pipeline between the cooling element 343 and the fermentation liquid output end 33. When the fermentation liquid temperature detected by the second temperature sensor 341 reaches the preset temperature, the third electric valve 344 is closed, the cooling is stopped and the fermentation liquid is allowed to flow back to the fermentation tank 1 to continue fermentation or perform other operations.

[0030] like Figure 1 and Figure 2 As shown, in order to facilitate cleaning of the fermentation tank 1 and mixing of the fermentation liquid, a cleaning and stirring assembly 4 is further provided in the fermentation tank 1. The cleaning and stirring assembly 4 includes a telescopic driving member 41, a cleaning pipe 42, a cleaning head 43 and a stirring blade 44.

[0031] The telescopic drive member 41 is arranged at the top of the fermentation tank 1. In this embodiment, a rodless cylinder is used as the telescopic drive member, and a mounting seat is provided for fixing the rodless cylinder. The cleaning pipe 42 is connected to the rodless cylinder and can be raised and lowered in the fermentation tank 1 under the drive of the rodless cylinder. The cleaning head 43 is arranged at the lower end of the cleaning pipe 42, and is used to spray cleaning liquid to clean the inner wall of the fermentation tank 1. The stirring blade 44 is arranged at the lower part of the cleaning pipe 42, and moves up and down with the lifting and lowering of the cleaning pipe 42 to stir the fermentation liquid in the fermentation tank 1.

[0032] Working principle: When in use, first, Chinese medicine raw materials are added to the fermentation tank 1 through the Chinese medicine raw material input port 12. Then, the strain liquid at a preset temperature is input into the fermentation tank 1 through the strain liquid constant temperature input device 2. The strain liquid input into the tank body is at a preset fermentation temperature. At the same time, the fermentation tank is heated to a suitable temperature by the heating interlayer, and fermentation can be started quickly. During the fermentation process, the fermentation liquid temperature control device 3 monitors and controls the temperature of the fermentation liquid in real time to ensure that the fermentation is carried out at a suitable temperature. When cooling is required, the fermentation liquid is cooled by the cooling element 343 in the second temperature control component.

[0033] After fermentation is completed, the fermented liquid can be discharged through the liquid discharge port 17. Meanwhile, to clean the fermenter 1 and prepare for the next batch of fermentation, the cleaning and stirring assembly 4 is started. The rodless cylinder drives the cleaning pipe 42 to move up and down in the fermenter 1, and the cleaning head 43 sprays cleaning liquid to clean the inner wall, while the stirring blade 44 moves up and down to stir the remaining fermented liquid and cleaning liquid, ensuring thorough cleaning.

[0034] The intelligent fermentation system provided by the present invention realizes precise temperature control of the strain liquid and the fermented liquid through the strain liquid constant temperature input device and the fermented liquid temperature control device, improving the fermentation efficiency and product quality. Meanwhile, the setting of the cleaning and stirring assembly facilitates the cleaning of the fermenter and the preparation for the next batch of fermentation, improving the practicability and convenience of the system.
