Description

Technical Field

[0001] This invention relates to the field of fermentation equipment technology, and in particular to a constant temperature fermentation unit and control process for traditional Chinese medicine decoction pieces. Background Technology

[0002] Medicinal slices include some processed Chinese herbal medicine slices, as well as slices that have been cut or roasted. During the production of Chinese herbal slices, some Chinese herbal slices will enhance or change the efficacy and properties of Chinese medicine through the metabolic activities of microorganisms, and improve the safety and effectiveness of its clinical application. This is mainly done by adding the slices into the fermentation pot for fermentation.

[0003] When fermenting raw materials for making Chinese herbal medicine, the fermentation temperature is extremely important. When the temperature is too low, the target microorganisms grow slowly, the fermentation cycle is prolonged, or it may even fail to start, which can easily lead to fermentation failure. If the temperature is too high, it will "kill" or inhibit the growth of the target microorganisms. Therefore, constant temperature is required for fermentation.

[0004] For example, the "Constant Temperature Fermentation Equipment for Traditional Chinese Medicine Pieces" with publication number "CN217868844U" mainly involves placing medicinal materials inside a fermentation tank and controlling a constant temperature resistance rod to ferment the medicinal materials at a constant temperature.

[0005] When raw materials for medicinal herbs are fermented, they are usually piled up. This causes microorganisms to generate heat through metabolism. If the raw materials are piled up too densely, the heat at the bottom of the raw materials cannot be dissipated, which can lead to excessively high local temperatures at the bottom of the raw materials. This can easily exceed the optimal growth range of the microorganisms and affect the effect of constant temperature fermentation. Summary of the Invention

[0006] The purpose of this invention is to provide a constant temperature fermentation unit for traditional Chinese medicine decoction pieces, which can realize the separate placement of raw materials to be fermented, reduce the excessive accumulation of raw materials, and thus reduce the difficulty in dissipating heat from the raw materials at the bottom due to the accumulation of raw materials. This reduces the possibility of excessively high local temperatures at the bottom of the raw materials and the occurrence of temperatures exceeding the optimal growth range of microorganisms, thereby improving the effect of constant temperature fermentation and solving the problems mentioned in the background art.

The leakage holes in adjacent distributing components are staggered. The lifting assembly is located at the rear end of the tank and is used to control the lifting and lowering of the blocking ring.

[0008] Preferably, the lifting assembly includes a lifting frame fixedly connected to the rear end of the blocking ring, the lifting frame being inclined on the right side. The lifting assembly also includes a servo electric cylinder fixedly connected to the rear end of the right side of the tank. The output shaft of the servo electric cylinder passes through the tank and is fixedly connected to a motion plate. Multiple extrusion frames are fixedly connected to the left side of the motion plate, the positions of the extrusion frames corresponding to the lifting frame. Horizontal plates are fixedly connected to both sides of the blocking ring, and magnetic blocks are fixedly connected inside the horizontal plates. The connecting blocks are made of magnetic material.

[0009] Preferably, the length of the extrusion frame gradually decreases from top to bottom, and the end of the extrusion frame is rotatably connected to a round shaft for reducing friction.

[0010] Preferably, the bottom of the lifting frame is fixedly connected with protrusions in a linear array.

[0011] Preferably, the tank body is equipped with a baffle assembly, which includes a baffle plate disposed inside the leakage hole, a bent frame slidably connected to the middle part of the baffle plate, the end of the bent frame being fixedly connected to the lifting rod, and a baffle rod being fixedly connected to the inner side of the leakage hole.

[0012] Preferably, except for the bottommost dispensing tray, the bottom of the dispensing tray and the top of the inner side of the tank are all fixedly connected to a fixing sleeve. The inner side of the blocking ring is equipped with a stirring assembly. The stirring assembly includes a round rod that moves inside the fixing sleeve. The outer wall of the round rod is provided with a guide groove. The inner side of the fixing sleeve is fixedly connected to a guide slider. The bottom of the guide groove is spiral-shaped. The guide slider moves inside the guide groove. The outer wall of the round rod is equipped with a bearing. The round rod is connected to a long rod through the bearing. The end of the long rod is fixedly connected to the inner side of the blocking ring. The bottom of the outer wall of the round rod is fixedly connected to a stirring plate.

[0013] Preferably, a ring is fixedly connected to the outer wall of the bending frame, and a spring is fixedly connected between the ring and the blocking disc.

[0014] Preferably, a small tube is fixedly connected to the top inner side of the fixing sleeve, the bottom of the small tube is inserted into the interior of the round rod where a small disc rotates, and an expansion bladder is fixedly connected to the outer wall of the bottom of the small tube, the interior of the expansion bladder communicating with the interior of the small tube. Preferably, a medium cylinder is fixedly connected to the inner wall of the tank, an electric telescopic rod is fixedly connected to the top of the medium cylinder, a piston plate is fixedly connected to the output shaft of the electric telescopic rod, the piston plate is in contact with the inner side of the medium cylinder, and a branch pipe is inserted into the bottom of the medium cylinder, with the branches of the branch pipe connected to multiple small pipes respectively.

[0015] The constant-temperature fermentation control process for traditional Chinese medicine decoction pieces includes the following steps: S1. Discharge: Place the fermentation raw materials inside different distribution components; S2, Fermentation: The fermented raw materials are placed inside the tank and fermented at a constant temperature.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This allows for the portioning and placement of raw materials during fermentation, reducing excessive accumulation and thus minimizing heat buildup at the bottom. This reduces the risk of localized overheating at the bottom of the raw materials, preventing temperatures from exceeding the optimal growth range for the microorganisms and improving the effectiveness of constant-temperature fermentation. 2. During the material addition stage, the output shaft of the servo electric cylinder can reciprocate with small amplitude extension and retraction. Under the pressure of the round shaft on the protrusion, the blocking ring can move up and down slightly on the outer edge of the elastic membrane. At this time, the elastic membrane shakes continuously, which facilitates the material to flow quickly and smoothly along the upper surface of the elastic membrane to the leakage hole, thereby improving the efficiency and accuracy of material placement. 3. The round rod begins to rotate, which causes the stirring plate to scrape the raw materials. This makes it easier to scrape the raw materials that have accumulated on the dispensing tray away from the drain hole, so that the raw materials are evenly distributed on the surface of the dispensing tray. This design further reduces the situation where the raw materials are excessively piled up, thereby reducing the difficulty in dissipating heat from the raw materials at the bottom due to the accumulation of raw materials, reducing the situation where the temperature exceeds the optimal growth range of the inoculum, and further improving the effect of constant temperature fermentation. 4. The expansion bladder expands, causing relative movement between the round rod, the small tube, and the fixed sleeve. At this time, under the action of the guide groove and the guide slider, the round rod and the stirring plate can rotate, scraping and mixing the raw materials during fermentation, further reducing the excessive accumulation of raw materials, thereby reducing the difficulty in dissipating heat from the raw materials at the bottom due to material accumulation, and further improving the fermentation effect.

[0020] 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.

[0021] Example 1: Please refer to Figures 1 to 10The present invention provides a technical solution: a constant temperature fermentation unit for traditional Chinese medicine decoction pieces, including a tank 1, a feed pipe 2 fixedly inserted into the top of the tank 1, and a discharge pipe 3 fixedly inserted into the bottom of the tank 1. The important raw materials to be fermented are added from the feed pipe 2 and fermented inside the tank 1. After the fermentation is completed, the fermented raw materials are discharged from the discharge pipe 3.

[0022] The constant temperature fermentation unit also includes a distribution assembly 4 disposed inside the tank 1. Multiple distribution assemblies 4 are configured for distributing raw materials. Each distribution assembly 4 includes connecting blocks 41 fixedly connected to both sides of the tank 1. A dispensing tray 42 is fixedly connected between two connecting blocks 41. Lifting rods 43 are slidably connected to both sides of the dispensing tray 42. A blocking ring 44 is fixedly connected to the top of the lifting rods 43. A leakage hole 45 is opened inside the dispensing tray 42. An elastic membrane 46 is fixedly connected between the inner side of the leakage hole 45 and the inner bottom of the blocking ring 44. The leakage holes 45 in adjacent distribution assemblies 4 are staggered. The constant temperature fermentation unit also includes a lifting assembly 5 disposed at the rear end of the tank 1. The lifting assembly 5 is used for controlling... The blocking ring 44 is raised and lowered. The lifting assembly 5 includes a lifting frame 51 fixedly connected to the rear end of the blocking ring 44. The lifting frame 51 is tilted on the right side. The lifting assembly 5 also includes a servo electric cylinder 52 fixedly connected to the rear end of the right side of the tank 1. The output shaft of the servo electric cylinder 52 passes through the tank 1 and is fixedly connected to a motion plate 53. Multiple extrusion frames 54 are fixedly connected to the left side of the motion plate 53. The position of the extrusion frames 54 corresponds to the lifting frame 51. Horizontal plates 47 are fixedly connected to both sides of the blocking ring 44. Magnetic blocks 48 are fixedly connected inside the horizontal plates 47. The connecting block 41 is made of magnetic material. The length of the extrusion frame 54 gradually decreases from top to bottom. A round shaft 55 for reducing friction is rotatably connected to the end of the extrusion frame 54.

[0023] The tank body 1 is equipped with a baffle assembly 6. The baffle assembly 6 includes a baffle plate 61 disposed inside. A bending frame 62 is slidably connected to the middle part of the baffle plate 61. The end of the bending frame 62 is fixedly connected to the lifting rod 43. The baffle rod 63 is fixedly connected to the inner side of the leakage hole 45.

[0024] When the lifting frame 51 is not compressed, under the magnetic force of the magnetic block 48, the bottom of the blocking ring 44 can contact the top of the dispensing tray 42. This design allows the lifting rod 43 to move downward with the bending frame 62 and the blocking tray 61. At this time, the blocking tray 61 can block the leakage hole 45. When the lifting frame 51 is compressed, the blocking ring 44 moves upward with the lifting rod 43, which allows the bending frame 62 and the blocking tray 61 to move upward as well. At this time, the bending frame 62 no longer blocks the leakage hole 45, which facilitates the discharge of materials.

[0025] By adopting the above technical solution, the feed pipe 2 is located on the other side of the topmost dispensing tray 42 with the outlet hole 45. When adding raw materials, it extends precisely through the output shaft of the servo electric cylinder 52, so that except for the bottom lifting frame 51 which is not squeezed by the corresponding extrusion frame 54, the rest of the lifting frames 51 are squeezed by the corresponding extrusion frame 54, and the ends of the rest of the extrusion frames 54 pass through the inclined part of the lifting frame 51.

[0026] When the extrusion frame 54 extrudes the lifting frame 51, the lifting frame 51 is tilted to the right, which causes the lifting frame 51 to move upward with the blocking ring 44 and the lifting rod 43. At this time, the elastic membrane 46 is stretched and deformed. The outer edge of the elastic membrane 46 moves upward with the rise of the blocking ring 44, so that the outer edge of the elastic membrane 46 is higher and tilted towards the position of the leakage hole 45, which facilitates the falling of materials.

[0027] Since only the bottommost lifting frame 51 is not compressed at this time, the raw material can fall inside the bottommost blocking ring 44. Then, through the output shaft of the servo electric cylinder 52, it gradually contracts, so that the lifting frame 51 is gradually not compressed from bottom to top, and the raw material to be fermented is added each time it is adjusted.

[0028] It should be noted that the amount of material added each time is the amount of raw material stored in a single distribution component 4.

[0029] It should be noted that the fermentation environment is usually a sealed environment, which makes it inconvenient to remove the container and add materials to the container.

[0030] This design allows for the separate placement of raw materials during fermentation, reducing excessive accumulation and minimizing heat buildup at the bottom. This reduces the risk of localized overheating at the bottom of the material, preventing temperatures from exceeding the optimal growth range for the microorganisms and thus improving the effectiveness of constant-temperature fermentation.

[0031] It should be noted that a temperature sensor is installed inside the tank 1, and a heat exchange component is installed inside the tank 1 to ensure the constant temperature inside the tank 1. This technology is a mature existing technology, and the technology to keep the temperature inside the tank 1 constant is a mature existing technology, so it will not be elaborated on further.

[0032] The bottom of the lifting frame 51 is fixedly connected with protrusions 56 in a linear array.

[0033] By adopting the above technical solution, during the material addition stage, the output shaft of the servo electric cylinder 52 can reciprocate with a small amplitude extension and retraction. Under the pressure of the round shaft 55 on the protrusion 56, the blocking ring 44 can move up and down slightly on the outer edge of the elastic membrane 46. At this time, the elastic membrane 46 shakes continuously, which facilitates the material to flow quickly and smoothly along the upper surface of the elastic membrane 46 to the leakage hole 45, thereby improving the efficiency and accuracy of material placement.

[0034] When all the material needs to be discharged, the output shaft of the servo electric cylinder 52 extends, causing all the lifting frames 51 to be squeezed, which allows all the fermented material above the dispensing trays 42 to be discharged.

[0035] When cleaning the inside of tank 1, water can be added through the feed pipe 2 for cleaning, and the clean water can be circulated for cleaning by simulating feeding.

[0036] Except for the bottommost dispensing tray 42, the bottom of the dispensing tray 42 and the top of the inner side of the tank 1 are all fixedly connected to the fixing sleeve 7. The inner side of the blocking ring 44 is equipped with a stirring assembly 8. The stirring assembly 8 includes a round rod 81 that moves inside the fixing sleeve 7. The outer wall of the round rod 81 is provided with a guide groove 82. The inner side of the fixing sleeve 7 is fixedly connected to a guide slider 83. The bottom of the guide groove 82 is spiral-shaped. The guide slider 83 moves inside the guide groove 82. The outer wall of the round rod 81 is equipped with a bearing 84. The round rod 81 is connected to a long rod 85 through the bearing 84. The end of the long rod 85 is fixedly connected to the inner side of the blocking ring 44. The bottom of the outer wall of the round rod 81 is fixedly connected to a stirring plate 86. The outer wall of the bent frame 62 is fixedly connected to a ring 64. A spring 65 is fixedly connected between the ring 64 and the blocking tray 61.

[0037] By adopting the above technical solution, after the material falls inside the blocking ring 44, the lifting frame 51 at this point is no longer squeezed due to the gradual contraction of the output shaft of the servo electric cylinder 52. At this time, under the magnetic force of the magnetic block 48, the blocking ring 44 moves downward with the long rod 85 and the bearing 84. The round rod 81 moves downward accordingly, and the guide slider 83 gradually moves inside the guide groove 82. When the guide slider 83 reaches the spiral position of the guide groove 82, the blocking disk 61 can block the leakage hole 45. At this time, the bottom of the blocking disk 61 contacts the top of the blocking rod 63 and is limited by the blocking rod 63. During this process, the bottom of the blocking ring 44 has not yet contacted the top of the blocking rod 63. As the top of the tray 42 contacts the bottom, the spring 65 deforms as the blocking ring 44 continues to descend, and the bent frame 62 continues to move downward. At this time, the guide slider 83 enters the spiral position of the guide groove 82. Under the action of the guide groove 82, the round rod 81 begins to rotate, thereby causing the stirring plate 86 to scrape the raw materials. This facilitates the scraping of the raw materials accumulated on the tray 42 away from the drain hole 45, making it easier for the raw materials to be evenly distributed on the surface of the tray 42. This design further reduces the situation of excessive accumulation of raw materials, thereby reducing the difficulty in dissipating heat from the raw materials at the bottom due to accumulation, reducing the situation where the temperature exceeds the optimal growth range of the inoculum, and further improving the effect of constant temperature fermentation.

[0038] Example 2: The technical solution of this example differs from that of Example 1 in that: Figures 1 to 6 and Figure 10 The inner top of the fixed sleeve 7 is fixedly connected to a small tube 9 which is inserted into the inside of the round rod 81 and rotates to a small disc 10. The bottom outer wall of the small tube 9 is fixedly connected to an expansion bladder 11, and the inside of the expansion bladder 11 is connected to the inside of the small tube 9. The inner wall of the tank 1 is fixedly connected to a medium cylinder 12. The top of the medium cylinder 12 is fixedly connected to an electric telescopic rod 13. The output shaft of the electric telescopic rod 13 is fixedly connected to a piston plate 15, which is in contact with the inner side of the medium cylinder 12. The bottom of the medium cylinder 12 is inserted with a branch pipe 14, and the branches of the branch pipe 14 are respectively connected to multiple small tubes 9. The stirring plate 86 is made of a material with high gravity.

[0039] By adopting the above technical solution, during the fermentation process, the output shaft of the electric telescopic rod 13 can be reciprocated to extend and retract, thereby causing the piston plate 15 to move in the up and down direction. When the piston plate 15 moves downward, the medium inside the medium cylinder 12 enters the branch pipe 14 and then the small pipe 9. Subsequently, the medium enters the expansion bladder 11, causing the expansion bladder 11 to expand. This causes the round rod 81 to move relative to the small pipe 9 and the fixed sleeve 7. At this time, under the action of the guide groove 82 and the guide slider 83, the round rod 81 and the stirring plate 86 can rotate, scraping and mixing the raw materials during fermentation, further reducing the excessive accumulation of raw materials, thereby reducing the difficulty in dissipating heat from the raw materials at the bottom due to the accumulation of raw materials, and further improving the fermentation effect.

[0040] When the output shaft of the electric telescopic rod 13 retracts, the medium returns to the medium cylinder 12, and under the gravity of the round rod 81 and the stirring plate 86, the round rod 81 and the stirring plate 86 return to their original positions.

[0041] It should be noted that when adding raw materials, the output shaft of the electric telescopic rod 13 is in the extended state.

[0042] The constant-temperature fermentation control process for traditional Chinese medicine decoction pieces includes the following steps: S1. Feeding: When adding raw materials, the output shaft of the servo electric cylinder 52 extends precisely, so that except for the bottom lifting frame 51 which is not squeezed by the corresponding squeezing frame 54, all other lifting frames 51 are squeezed by the corresponding squeezing frame 54. The ends of the other squeezing frames 54 pass through the inclined part of the lifting frame 51. When the squeezing frame 54 squeezes the lifting frame 51, under the action of the right side of the lifting frame 51, the lifting frame 51 can move upward with the blocking ring 44 and the lifting rod 43. At this time, the elastic membrane 46 is stretched and deformed. At this time, the outer edge of the elastic membrane 46 moves upward with the rise of the blocking ring 44. This makes the outer edge of the elastic membrane 46 higher and inclined towards the position of the leakage hole 45, which facilitates the material to fall. Since only the bottom lifting frame 51 is not squeezed at this time, the raw material can fall inside the bottom blocking ring 44. Then, the output shaft of the servo electric cylinder 52 gradually retracts, so that the lifting frame 51 is gradually stopped from being squeezed from bottom to top. The raw material to be fermented is added each time the adjustment is made. S2, Fermentation: The fermented raw materials are placed in tank 1 and fermented at a constant temperature.

[0043] Working principle: Since only the bottom lifting frame 51 is not compressed at this time, the raw material can fall inside the bottom blocking ring 44. Then, the output shaft of the servo electric cylinder 52 gradually contracts, so that the lifting frame 51 is gradually depressed from bottom to top. The raw material to be fermented is added at each adjustment. During fermentation, the raw material to be fermented can be divided and placed to reduce the excessive accumulation of raw material. This reduces the heat of the raw material at the bottom that is difficult to dissipate due to the accumulation of raw material, thereby reducing the local temperature of the raw material at the bottom from being too high and reducing the temperature from exceeding the optimal growth range of the strain, thus improving the effect of constant temperature fermentation.

[0044] By adopting the above technical solution, during the material addition stage, the output shaft of the servo electric cylinder 52 can reciprocate with a small amplitude. Under the pressure of the round shaft 55 on the protrusion 56, the blocking ring 44 can move up and down slightly on the outer edge of the elastic membrane 46. At this time, the elastic membrane 46 shakes continuously, which facilitates the raw material to flow quickly and smoothly along the upper surface of the elastic membrane 46 to the leakage hole 45, thereby improving the efficiency and accuracy of material placement. When all the material needs to be discharged, the output shaft of the servo electric cylinder 52 extends, so that all the lifting frames 51 are squeezed, which allows all the fermented material above the dispensing trays 42 to be discharged.

[0045] After the material falls inside the blocking ring 44, the lifting frame 51 at this point is no longer squeezed due to the gradual retraction of the output shaft of the servo electric cylinder 52. At this time, under the magnetic force of the magnetic block 48, the blocking ring 44 moves downward with the long rod 85 and the bearing 84. The round rod 81 moves downward accordingly, and the guide slider 83 gradually moves inside the guide groove 82. When the guide slider 83 reaches the spiral position of the guide groove 82, the blocking disk 61 can block the leakage hole 45. At this time, the bottom of the blocking disk 61 contacts the top of the blocking rod 63 and is limited by the blocking rod 63. During this process, the bottom of the blocking ring 44 has not yet contacted the top of the dispensing tray 42. As the blocking ring 44 continues to descend, the spring 65 deforms, and the bent frame 62 continues to move downward. At this time, the guide slider 83 enters the spiral position of the guide groove 82. Under the action of the guide groove 82, the round rod 81 begins to rotate, thereby causing the stirring plate 86 to scrape the raw materials. This facilitates the scraping of the raw materials accumulated on the dispensing tray 42 away from the leakage hole 45, making it easier for the raw materials to be evenly distributed on the surface of the dispensing tray 42. This design further reduces the situation of excessive accumulation of raw materials, thereby reducing the difficulty in dissipating heat from the raw materials at the bottom due to accumulation of raw materials, reducing the situation where the temperature exceeds the optimal growth range of the inoculum, and further improving the effect of constant temperature fermentation.

[0046] During fermentation, the output shaft of the electric telescopic rod 13 can be reciprocated to extend and retract, causing the piston plate 15 to move in the up-down direction. When the piston plate 15 moves downward, the medium inside the medium cylinder 12 enters the branch pipe 14 and then the small pipe 9. Subsequently, the medium enters the expansion bladder 11, causing the expansion bladder 11 to expand. This causes the round rod 81 to move relative to the small pipe 9 and the fixed sleeve 7. At this time, under the action of the guide groove 82 and the guide slider 83, the round rod 81 and the stirring plate 86 can rotate, scraping and mixing the raw materials during fermentation. This further reduces the excessive accumulation of raw materials, thereby reducing the difficulty in dissipating heat from the raw materials at the bottom due to accumulation, and further improving the fermentation effect.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
