Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine fermentation technology, specifically to a device for temperature-controlled fermentation of traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine fermentation involves extracting and purifying medicinal herbs that are both food and medicine, and then anaerobic fermenting them with a selected group of probiotic strains. Under certain environmental conditions (such as temperature, humidity, air, and water), the extracted active ingredients of the herbs undergo biological transformation, turning the large molecules of the herbs into small molecules that can be directly absorbed by the human intestines.

[0003] Liquid fermentation is a modern fermentation technology that relies on antibiotic production processes. Well-grown mycelia are inoculated into a culture medium containing a certain proportion of Chinese medicinal materials, and then the culture medium is placed under suitable environmental conditions for fermentation.

[0004] Currently, a stable temperature environment plays a crucial role in the liquid fermentation of traditional Chinese medicine (TCM). For example, Chinese invention patent CN114540186B discloses a temperature-controlled TCM fermentation device, comprising a lower-opening box and a base plate. An adjustable-lift drug-carrying component is installed on the base plate. A main pipe is rotatably mounted on the top of the lower-opening box, and a drive component for rotating the main pipe and a hot air inlet component for supplying hot air at a certain temperature to the main pipe are installed on the lower-opening box. Multiple temperature-controlled aeration dynamic disturbance components are circumferentially distributed on the inner side of the lower-opening box around the main pipe. An adjustment component is also installed at the top inner side of the lower-opening box, controlling the horizontal position of the temperature-controlled aeration dynamic disturbance components within the adjustable-lift drug-carrying component, thereby dynamically adjusting the disturbance, aeration, and fermentation temperature. This invention can effectively agitate the medicinal materials and maintain stable temperature control, improving the fermentation speed and quality.

[0005] The technology used in the aforementioned patent controls the temperature of the fermentation liquid by introducing air at a certain temperature into the fermentation liquid. In this method, air at a certain temperature needs to be continuously introduced into the fermentation liquid, which can easily cause bacteria and other impurities from the external environment to enter the fermentation liquid along with the air at a certain temperature, resulting in contamination of the fermentation liquid. Summary of the Invention

[0006] The purpose of this invention is to provide a temperature-controlled fermentation device for traditional Chinese medicine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A temperature-controlled fermentation device for traditional Chinese medicine includes a fermentation tank, a heating unit for heating the fermentation liquid inside the fermentation tank, and a lifting unit for driving the heating unit to move up and down inside the fermentation tank. The heating unit includes a vertically arranged pipe and multiple heat transfer rings fixedly connected to the bottom end of the pipe and coaxially arranged with the pipe. The multiple heat transfer rings are arranged in sequence from the inside to the outside. The heat transfer oil flows through the multiple heat transfer rings from the outside to the inside through the pipe and then is discharged through the pipe. The heating unit is equipped with an oxygenation unit, which introduces air from the top of the fermentation tank into the fermentation liquid and then discharges it in the form of bubbles.

[0008] Preferably, the oxygenation unit includes a fixing seat fixed between the pipe and multiple heat transfer rings. The fixing seat is horizontally arranged, and the bottom surface of the fixing seat is recessed upward to form a receiving cavity. The upper surface of the fixing seat has a conical hole communicating with the receiving cavity.

[0009] Preferably, the oxygenation unit further includes a fixing plate fixed to the side of the pipe and arranged parallel to the fixing seat. The fixing plate is located directly above the fixing seat, and a guide column is vertically slidably connected to the fixing plate. A float is fixed to the top of the guide column, and a tapered insert matching the tapered hole is fixed to the bottom of the guide column.

[0010] Preferably, the interior of the pipeline is divided into an independent oil inlet channel and an oil outlet channel by a middle partition. The top end of the oil inlet channel is fixedly connected to a first oil inlet pipe, and the bottom end of the oil inlet channel is connected to the outermost heat transfer ring through a second oil inlet pipe. The two adjacent heat transfer rings and the bottom end of the oil outlet channel are connected to the innermost heat transfer ring through a second oil outlet pipe. The top end of the oil outlet channel is fixedly connected to a first oil outlet pipe.

[0011] Preferably, the heat transfer ring is hollow inside and has a fixed partition, which makes the interior of the heat transfer ring form an open annular channel. The heat transfer oil enters from one end of the open annular channel and exits from the other end.

[0012] Preferably, an annular sealing sleeve is fitted onto the outer circumferential surface of the outermost heat transfer ring, and the outer circumferential surface of the annular sealing sleeve is slidably and sealingly connected to the inner circumferential surface of the fermenter. Connecting plates and filters are provided between two adjacent heat transfer rings and between the pipe and the innermost heat transfer ring, with the filters fixed to the bottom of the connecting plates.

[0013] Preferably, a grinding unit is provided between the heating unit and the lifting unit; The grinding unit includes a vertical cylinder fixed to the top of the pipe and coaxially arranged with the pipe, a spiral hole opened on the side of the vertical cylinder, and a horizontal bar that passes through the spiral hole and is arranged horizontally. Both ends of the horizontal bar are connected to the lifting unit through connecting vertical plates.

[0014] Preferably, the grinding unit further includes a circular plate and a spring disposed inside the vertical cylinder, the bottom end of the spring being fixedly connected to the bottom of the vertical cylinder, and the top end of the spring being fixedly connected to the circular plate and a crossbar.

[0015] Preferably, the lifting unit includes a vertically arranged hydraulic cylinder and a connecting frame fixed to the end of the piston rod of the hydraulic cylinder, and the connecting vertical plate is fixedly connected to the connecting frame.

[0016] Preferably, the fermenter includes a tank body with a top opening and a tank lid installed at the top opening of the tank body.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention, through the oxygenation unit, can introduce air above the surface of the fermentation liquid into the fermentation liquid, and then release it into the fermentation liquid in the form of small bubbles, thereby increasing the oxygen content inside the fermentation liquid. Since the air is obtained from inside the fermentation tank, there is no risk of bacterial contamination of the fermentation liquid. At the same time, the lifting unit drives the heating unit to move up and down inside the fermentation liquid. On the one hand, the heating unit can stir and mix the fermentation liquid, improving the mixing uniformity between the solid Chinese medicinal materials and the fermentation liquid. On the other hand, it can increase the contact area between the heating unit and the fermentation liquid, thereby accelerating the heating rate of the fermentation liquid. At the same time, when the heating unit descends to the lowest position, it can also squeeze the solid Chinese medicinal materials, increasing the contact area between them and the fermentation liquid, thereby accelerating the overall fermentation efficiency.

[0018] 2. This invention, through the design of an annular sealing sleeve and filter screen, ensures that large-volume Chinese medicinal herbs inside the fermentation broth are always blocked in the fermentation broth below the heat transfer ring. This prevents the presence of large-volume Chinese medicinal herbs in the fermentation broth above the heat transfer ring, facilitating rapid solid-liquid separation after fermentation. Furthermore, the combination of the annular sealing sleeve and filter screen keeps large-volume Chinese medicinal herbs within the fermentation broth below the heat transfer ring, allowing them to accumulate and facilitating compression by the heat transfer ring, increasing the contact area between the large-volume herbs and the fermentation broth. Simultaneously, the annular sealing sleeve and filter screen prevent large-volume Chinese medicinal herbs from clogging the conical orifice.

[0019] 3. The present invention, through the grinding unit, utilizes the cooperation of the spiral hole and the crossbar to convert the downward movement of the lifting unit into the rotational movement of the heat transfer ring, thereby realizing the squeezing and grinding action of the heat transfer ring on the Chinese medicinal materials, achieving rapid pulverization of the Chinese medicinal materials, increasing the contact area between the Chinese medicinal materials and the fermentation liquid, and helping to improve the actual fermentation efficiency.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-10 The present invention provides a technical solution: A temperature-controlled fermentation device for traditional Chinese medicine includes a fermentation tank 1, a heating unit 2 for heating the fermentation liquid inside the fermentation tank 1, and a lifting unit 3 for driving the heating unit 2 to move up and down inside the fermentation tank 1. Specifically, the fermentation liquid is loaded into the fermentation tank 1, and then the lifting unit 3 drives the heating unit 2 to move vertically up and down, thereby enabling the heating unit 2 to heat the fermentation liquid. In this embodiment, the lifting unit 3 can drive the heating unit 2 to move between a position lowered to the bottom of the fermentation liquid and a position raised above the surface of the fermentation liquid.

[0024] like Figure 1 As shown, the lifting unit 3 includes a vertically arranged hydraulic cylinder 31 and a connecting frame 32 fixed to the end of the piston rod of the hydraulic cylinder 31. The connecting vertical plate 55 is fixedly connected to the connecting frame 32. Figure 1 As shown, the fermentation tank 1 includes a tank body 11 with a top opening and a tank cover 12 installed at the top opening of the tank body 11.

[0025] like Figures 1 to 4 As shown, the heating unit 2 includes a vertically arranged pipe 21 and multiple heat transfer rings 22 fixedly connected to the bottom end of the pipe 21 and coaxially arranged with the pipe 21. The multiple heat transfer rings 22 are arranged in sequence from the inside to the outside. In this embodiment, the number of heat transfer rings 22 is set to three. The heat transfer oil flows through the three heat transfer rings 22 from the outside to the inside through the pipe 21 and then is discharged through the pipe 21. The heat transfer oil is transported using existing technology. For example, the heat transfer oil can be heated by a heat transfer oil furnace and then pumped into the interior of the heating unit 2 by a heat transfer oil pump, so that a circulation can be formed between the heating unit 2 and the heat transfer oil furnace, continuously heating the fermentation liquid at a constant temperature, thereby achieving stable control of the fermentation liquid temperature.

[0026] In this embodiment, a sliding sleeve is provided between the pipe 21 and the can lid 12. The sliding sleeve can realize the lifting and sliding of the pipe 21 on the can lid 12, and also allow the pipe 21 to rotate relative to the can lid 12. Specifically, the sliding sleeve can be composed of a stainless steel sleeve and a sealing ring embedded in the inner wall of the stainless steel sleeve.

[0027] Furthermore, such as Figure 2As shown, the heating unit 2 is equipped with an oxygenation unit 4 for increasing the oxygen content inside the fermentation liquid. The oxygenation unit 4 introduces air from the top of the fermentation tank 1 into the fermentation liquid and then discharges it in the form of bubbles. Specifically, when the fermentation tank 1 contains fermentation liquid, the bottom of the fermentation tank 1 is the fermentation liquid layer and the top is the air layer. In this embodiment, the oxygenation unit 4 introduces the air located in the air layer into the fermentation liquid and then discharges it into the fermentation liquid in the form of small bubbles. In this way, the oxygen content inside the fermentation liquid can be increased.

[0028] The oxygenation unit 4 introduces air from above the fermentation liquid into the fermentation liquid, which is then released into the liquid as small bubbles, thus increasing the oxygen content. Since the air is drawn from inside the fermentation tank 1, there is no risk of bacterial contamination. Simultaneously, the lifting unit 3 drives the heating unit 2 to move up and down within the fermentation liquid. This allows the heating unit 2 to stir and mix the fermentation liquid, improving the uniformity of mixing between the solid medicinal herbs and the liquid. It also increases the contact area between the heating unit 2 and the fermentation liquid, accelerating the temperature rise. Furthermore, when the heating unit 2 descends to its lowest point, it can compress the solid medicinal herbs, further increasing their contact area with the fermentation liquid, thus accelerating the overall fermentation process.

[0029] Furthermore, such as Figures 7 to 8As shown, the oxygenation unit 4 includes a fixing seat 41 fixed between the pipe 21 and multiple heat transfer rings 22. The fixing seat 41 is horizontally arranged. Specifically, the fixing seat 41 has a cuboid structure. The bottom surface of the fixing seat 41 is fixedly connected to the heat transfer rings 22, and the end face of the fixing seat 41 is fixedly connected to the pipe 21. This can improve the connection strength between the pipe 21 and the heat transfer rings 22 and improve the structural stability of the entire heating unit 2. The bottom surface of the fixing seat 41 is recessed upward to form a receiving cavity 411. The upper surface of the fixing seat 41 is provided with a conical hole 412 communicating with the receiving cavity 411. In this embodiment, there are three conical holes 412. In actual use, when the heating unit 2 is driven by the lifting unit 3 to rise to the highest position, that is, when the heating unit 2 is located in the air layer above the surface of the fermentation liquid, the fixing seat... The internal storage cavity 411 is filled with air. Then, the fixed seat 41 will descend along with the heating unit 2 under the drive of the lifting unit 3. At this time, the bottom opening of the storage cavity 411 will first come into contact with the fermentation liquid. Since the amount of air that can be discharged through the conical hole 412 is extremely limited, as the fixed seat 41 gradually sinks into the fermentation liquid, the air collected in the storage cavity 411 will not be completely discharged through the conical hole 412 in a short time. Instead, it will be discharged slowly through the conical hole 412 as the fixed seat 41 sinks. In this way, when the fixed seat 41 is completely submerged in the fermentation liquid, the air collected in the storage cavity 411 will be discharged through the conical hole 412, forming small bubbles inside the fermentation liquid. This can increase the oxygen content inside the fermentation liquid, which is beneficial to the fermentation of Chinese medicinal materials.

[0030] Furthermore, such as Figures 7 to 8 As shown, the oxygenation unit 4 also includes a fixing plate 43 fixed to the side of the pipe 21 and arranged parallel to the fixing seat 41. The fixing plate 43 is located directly above the fixing seat 41, and a guide post 44 is vertically slidably connected to the fixing plate 43. A float 45 is fixed to the top of the guide post 44, and a tapered insert 42 that matches the tapered hole 412 is fixed to the bottom of the guide post 44. In actual use, when the heating unit 2 is located in the air layer above the surface of the fermentation liquid, the conical insert 42 is inserted into the conical hole 412 under the action of gravity to seal the conical hole 412. When the part below the float 45 is submerged below the fermentation liquid, the conical insert 42 is still inserted into the conical hole 412. At this time, the air inside the storage cavity 411 cannot be discharged through the conical hole 412. Only when the float 45 is about to enter the fermentation liquid, because the float 45 can generate buoyancy in the fermentation liquid, when the fixed seat 41 is a certain distance away from the surface of the fermentation liquid, the conical insert 42 will be withdrawn from the inside of the conical hole 412 under the action of the buoyancy of the float 45. At this time, the air collected inside the storage cavity 411 can be discharged through the conical hole 412.

[0031] In the above scheme, the conical insert 42 and float 45 allow the operator to control the depth at which the conical hole 412 discharges air from the receiving cavity 411 by adjusting the length of the guide post 44.

[0032] like Figure 4 As shown, the upper and lower ends of the pipe 21 are sealed. The interior of the pipe 21 is divided into an independent oil inlet channel 212 and an oil outlet channel 213 by a middle partition 211. The top end of the oil inlet channel 212 is fixedly connected to a first oil inlet pipe 214, and the bottom end of the oil inlet channel 212 is connected to the outermost heat transfer ring 22 through a second oil inlet pipe 23. The two adjacent heat transfer rings 22 are connected to each other, and the bottom end of the oil outlet channel 213 is connected to the innermost heat transfer ring 22 through a second oil outlet pipe 24. The top end of the oil outlet channel 213 is fixedly connected to a first oil outlet pipe 215; furthermore, as Figure 3 As shown, the heat transfer ring 22 is hollow inside and has a fixed partition 221. The partition 221 allows the heat transfer ring 22 to form an open annular channel 222 inside. The heat transfer oil enters from one end of the open annular channel 222 and exits from the other end. The pipe 21, heat transfer ring 22, second oil inlet pipe 23 and second oil outlet pipe 24 mentioned above can all be made of stainless steel to increase the heat exchange efficiency between the heat transfer oil and the fermentation liquid.

[0033] The heat transfer oil flows as follows: the heat transfer oil first enters the interior of the oil inlet channel 212 through the first oil inlet pipe 214, and then enters the outermost heat transfer ring 22 through the second oil inlet pipe 23, that is, it enters one circumferential end of the unclosed annular channel 222 inside the outermost heat transfer ring 22. Then the heat transfer oil flows along the unclosed annular channel 222 to the other circumferential end of the unclosed annular channel 222. After completion, the heat transfer oil enters the interior of the middle heat transfer ring 22 through the second oil outlet pipe 24 from the outermost heat transfer ring 22. In this way, the heat transfer oil will flow to the bottom of the oil outlet channel 213, and finally be discharged through the first oil outlet pipe 215 at the top of the oil outlet channel 213. The above is the flow path of the heat transfer oil inside the heating unit 2.

[0034] like Figure 2 As shown, an annular sealing sleeve 25 is fitted onto the outer circumferential surface of the outermost heat transfer ring 22. The outer circumferential surface of the annular sealing sleeve 25 is slidably sealed to the inner circumferential surface of the fermentation tank 1. This prevents the medicinal materials in the fermentation liquid from entering the area above the heat transfer ring 22 through the gap between the outermost heat transfer ring 22 and the inner wall of the fermentation tank 1. Furthermore, as shown... Figures 5 to 6As shown, connecting plates 26 and filter screens 27 are provided between two adjacent heat transfer rings 22 and between pipe 21 and the innermost heat transfer ring 22. The filter screen 27 is fixed to the bottom of the connecting plate 26. The connecting plate 26 can also be made of stainless steel, which can increase the contact area between the heat transfer ring 22 and the fermentation liquid, resulting in better heat transfer effect. It can also further improve the connection strength between two adjacent heat transfer rings 22 and between pipe 21 and the innermost heat transfer ring 22. The filter screen 27 can effectively prevent the Chinese medicinal materials in the fermentation liquid from entering the upper part of the heat transfer ring 22 through the gaps between two adjacent heat transfer rings 22 and between pipe 21 and the innermost heat transfer ring 22. Specifically, when the lifting unit 3 drives the heating unit 2 to move down inside the fermentation liquid, due to the presence of the annular sealing sleeve 25 and the filter screen 27, large-volume Chinese medicinal materials inside the fermentation liquid will always be blocked in the fermentation liquid below the heat transfer ring 22. This ensures that there are no large-volume Chinese medicinal materials in the fermentation liquid above the heat transfer ring 22.

[0035] In the above scheme, the annular sealing sleeve 25 and filter screen 27 ensure that large-volume Chinese medicinal materials inside the fermentation liquid are always blocked in the fermentation liquid below the heat transfer ring 22. This ensures that there are no large-volume Chinese medicinal materials in the fermentation liquid above the heat transfer ring 22, thus facilitating rapid solid-liquid separation after fermentation. On the other hand, the combination of the annular sealing sleeve 25 and filter screen 27 ensures that large-volume Chinese medicinal materials inside the fermentation liquid are always blocked in the fermentation liquid below the heat transfer ring 22, achieving the aggregation of large-volume Chinese medicinal materials. This facilitates the compression of these Chinese medicinal materials by the heat transfer ring 22, increasing the contact area between the large-volume Chinese medicinal materials and the fermentation liquid. At the same time, the annular sealing sleeve 25 and filter screen 27 prevent large-volume Chinese medicinal materials from being present in the fermentation liquid above the heat transfer ring 22, thus preventing the conical hole 412 from being blocked by large-volume Chinese medicinal materials. The conical insert 42 also has the function of pushing out the Chinese medicinal materials stuck inside the conical hole 412, further improving the anti-blocking effect.

[0036] Furthermore, such as Figure 1 and Figure 2 As shown, a grinding unit 5 is provided between the heating unit 2 and the lifting unit 3. In this embodiment, the grinding unit 5 can convert the downward motion of the lifting unit 3 into rotational motion, so that the heat transfer ring 22 will rotate at a certain angle during the process of squeezing the Chinese medicinal materials, thereby completing the crushing and grinding of the Chinese medicinal materials, so as to accelerate the crushing speed of the Chinese medicinal materials, further increase the contact area between the Chinese medicinal materials and the fermentation liquid, and accelerate the fermentation efficiency.

[0037] like Figure 9 and Figure 10As shown, the grinding unit 5 includes a vertical cylinder 51 fixed to the top of the pipe 21 and coaxially arranged with the pipe 21, a spiral hole 511 opened on the side of the vertical cylinder 51, and a horizontal bar 52 that passes through the spiral hole 511 and is arranged horizontally. The outer diameter of the vertical cylinder 51 is equal to the outer diameter of the pipe 21. The vertical cylinder 51 and the pipe 21 can be fixedly connected by bolts. Both ends of the horizontal bar 52 are connected to the lifting unit 3 through connecting vertical plates 55. The grinding unit 5 also includes a circular plate 53 and a spring 54 disposed inside the vertical cylinder 51. The circular plate 53 is slidably connected inside the vertical cylinder 51. The bottom end of the spring 54 is fixedly connected to the bottom of the vertical cylinder 51. The top end of the spring 54 is fixedly connected to the circular plate 53 and the horizontal bar 52.

[0038] The specific working principle of the grinding unit 5 is as follows: When the heat transfer ring 22 moves down to contact the Chinese medicinal materials gathered at the bottom of the fermentation tank 1 under the driving action of the lifting unit 3, the lifting unit 3 will continue to drive the connecting frame 32 to move down. At this time, since the bottom surface of the heat transfer ring 22 is pressed against the Chinese medicinal materials, the displacement that the heat transfer ring 22 can move down is limited. At this time, the crossbar 52 will drive the circular plate 53 to squeeze the spring 54. The spring 54 contracts and generates elasticity. This elasticity is transmitted to the heat transfer ring 22 through the vertical cylinder 51 and the pipe 21, increasing the force of the heat transfer ring 22 on the Chinese medicinal materials. At the same time, due to the existence of the spiral hole 511, the crossbar 52 will also drive the vertical cylinder 51 to rotate during the downward movement, thereby driving the pipe 21 and the heat transfer ring 22 to rotate, completing the crushing and grinding of the Chinese medicinal materials.

[0039] In the above scheme, the grinding unit 5, through the cooperation of the spiral hole 511 and the crossbar 52, converts the downward movement of the lifting unit 3 into the rotational movement of the heat transfer ring 22, thereby realizing the squeezing and grinding action of the heat transfer ring 22 on the Chinese medicinal materials, realizing the rapid crushing of the Chinese medicinal materials, increasing the contact area between the Chinese medicinal materials and the fermentation liquid, which is conducive to improving the actual fermentation efficiency.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
