Description

Technical Field

[0001] The present invention belongs to the technical field of fermentation devices, and in particular relates to a fermentation device for a medicinal and edible plant extract. Background Art

[0002] Fermentation refers to the process in which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare microbial cells themselves, or direct metabolites or secondary metabolites. Fermentation is sometimes also written as fermentation, and its definition varies depending on the usage scenario. The fermentation device for medicinal and edible plant extracts is a special equipment specially used for fermenting medicinal and edible plant raw materials to extract their active ingredients and prepare functional fermentation products.

[0003] Existing fermentation equipment for medicinal and edible plant extracts struggles to fully crush the wet residue after extraction due to the raw material's remaining moisture and fiber toughness. This results in incomplete release of the active ingredients in the residue, impacting fermentation efficiency. Furthermore, during the filtration and screening process, the fine fibers and colloids in the wet residue easily adhere to and clog the filter plates. Existing cleaning methods are difficult to thoroughly remove without disassembling the filter plates, leading to production interruptions and further reducing fermentation efficiency. Summary of the Invention

[0008] Furthermore, the second transmission mechanism includes a second gear belt arranged on the third gear, the second gear belt is transmission-connected to a fourth gear, the fourth gear is rotatably mounted on the mixing box, the fourth gear is fixedly mounted with a rotating shaft, the rotating shaft is rotatably mounted inside the mixing box, the rotating shaft is fixedly mounted with a cam, and several cams are provided.

[0009] Furthermore, the filter screen plate is inclined, the mixing box is provided with a discharge port, the discharge port is located at one end of the inclined filter screen plate, the mixing box is fixedly installed with a collection box, the collection box is located below the discharge port, the discharge port is rotatably installed with a rotating plate, and the collection box is designed with an inclination angle for collecting residue.

[0010] Furthermore, the fourth gear is connected to the fifth gear through the third gear belt transmission, the fifth gear is rotatably mounted on the mixing box, the fifth gear is fixedly mounted with a mixing shaft, and the mixing shaft is rotatably mounted inside the mixing box.

Furthermore, the interconnected structure of the crushing chamber and the mixing chamber ensures continuous operation from crushing, extrusion, filtration, to mixing, reducing equipment downtime and improving production efficiency. Furthermore, a one-way control valve at the bottom of the mixing chamber prevents liquid backflow, further ensuring stable operation.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figures 1-6 As shown, the present invention is a fermentation device for a plant extract of medicinal and edible properties, comprising a crushing box 1, wherein two crushing rollers 2 are rotatably installed inside the crushing box 1, and the two crushing rollers 2 are fixedly installed with a first gear 3, and the two first gears 3 are meshed with each other, and one of the crushing rollers 2 is fixedly installed with the output end of a driving motor 4, and the crushing box 1 is fixedly connected to a stirring box 5, and a filter screen 6 is movably installed inside the stirring box 5, and a first transmission mechanism is provided at the output end of the driving motor 4, and the first transmission mechanism is used to drive a third gear 12 to rotate, and the third gear 12 is fixedly installed on a bidirectional threaded rod 7, and the bidirectional threaded rod 7 is rotatably installed inside the stirring box 5, and extrusion plates 8 are meshed at both ends of the bidirectional threaded rod 7, and the bidirectional threaded rod 7 is provided with a second transmission mechanism, and the second transmission mechanism is used to drive a cam 9 to rotate, and the raised end of the cam 9 contacts the bottom of the filter screen 6, and the stirring box 5 is fixedly connected to a strain feed port 22.

[0024] The working principle of the plant extract fermentation device for medicinal and edible plants proposed in this invention is as follows: after the drive motor 4 is started, it drives one crushing roller 2 to rotate. The other crushing roller 2 is driven in the opposite direction by two intermeshing first gears 3. After the medicinal and edible plant material enters the crushing box 1, it is squeezed and crushed by the two crushing rollers 2. The crushed material falls into the mixing box 5 connected to the crushing box 1 and accumulates on the movable filter screen 6.

[0025] The output end of the drive motor 4 drives the third gear 12 to rotate through the first transmission mechanism, and the third gear 12 drives the bidirectional threaded rod 7 to rotate, so that the two extrusion plates 8 engaged at both ends of the bidirectional threaded rod 7 move horizontally in opposite directions, bidirectionally squeezing the material on the filter screen plate 6, and prompting the extract to pass through the filter screen plate 6 and enter the lower part of the mixing box 5.

[0026] The bidirectional threaded rod 7 drives the cam 9 to rotate through the second transmission mechanism, and the raised end of the cam 9 periodically pushes the bottom of the filter screen plate 6 to make the filter screen plate 6 vibrate to avoid clogging of the filter holes.

[0027] The bacterial strain is introduced into the lower portion of the mixing tank 5 through the strain feed port 22 and mixed with the extracted liquid after extrusion and filtration. The mixed material is then conveyed by gravity or pressure to the subsequent fermentation process. The entire process is completed by a single drive motor 4 to complete the crushing, extrusion, filtration, and mixing operations, realizing an integrated fermentation pretreatment function for the medicinal and edible plant extract.

[0028] In one embodiment, for the first gears 3 , both first gears 3 are rotatably mounted on the crushing box 1 , and the drive motor 4 is fixedly mounted on the crushing box 1 .

[0029] In one embodiment, for the above-mentioned first transmission mechanism, the first transmission mechanism includes a second gear 10 fixedly mounted on the output end of the drive motor 4, the second gear 10 is connected to the third gear 12 through the first gear belt 11, the third gear 12 is fixedly mounted with a bidirectional threaded rod 7, and the two extrusion plates 8 are both fitted with the upper surface of the filter plate 6 and are slidably connected to the inside of the mixing box 5.

[0030] The working principle of the plant extract fermentation device for medicinal and edible plants proposed in the present invention is as follows: in the first transmission mechanism at the output end of the drive motor 4, the second gear 10 fixed thereto drives the third gear 12 to rotate via the first gear belt 11, and the third gear 12 drives the bidirectional threaded rod 7 fixed thereto to rotate. The opposing threads at both ends of the bidirectional threaded rod 7 respectively engage with two extrusion plates 8, causing the two extrusion plates 8 to move toward or in opposite directions horizontally, bidirectionally squeezing the material on the filter screen plate 6, causing the extract to pass through the filter screen plate 6 and enter the lower part of the mixing box 5. As the extrusion plates 8 move, they always adhere to the upper surface of the filter screen plate 6 and slide along the inner wall of the mixing box 5.

[0031] In one embodiment, for the above-mentioned second transmission mechanism, the second transmission mechanism includes a second gear belt 13 arranged on the third gear 12, the second gear belt 13 is transmission-connected to the fourth gear 14, the fourth gear 14 is rotatably mounted on the mixing box 5, the fourth gear 14 is fixedly mounted with a rotating shaft 15, the rotating shaft 15 is rotatably mounted inside the mixing box 5, the rotating shaft 15 is fixedly mounted with a cam 9, and several cams 9 are provided.

[0032] In one embodiment, for the above-mentioned filter screen plate 6, the filter screen plate 6 is inclined, and the mixing box 5 is provided with a discharge port 16, which is located at one end of the inclined filter screen plate 6. The mixing box 5 is fixedly installed with a collecting box 17, and the collecting box 17 is located below the discharge port 16. The discharge port 16 is rotatably installed with a rotating plate 18, and the collecting box 17 is designed with an inclination angle for collecting residue.

[0033] The working principle of the medicinal and edible plant extract fermentation device proposed in this invention is that when the third gear 12 rotates with the bidirectional threaded rod 7, the second gear belt 13 on its outer edge synchronously drives the fourth gear 14 to rotate. The fourth gear 14 then drives the rotating shaft 15 fixed at its center to rotate within the mixing tank 5. Multiple cams 9 evenly distributed along the axial direction of the rotating shaft 15 rotate synchronously with the shaft, and the raised ends of each cam 9 are arranged with a fixed phase difference.

[0034] As cam 9 rotates, its raised end sequentially pushes against different locations on the bottom of the tilted filter screen 6, causing it to vibrate. The tilt of the filter screen 6 causes the inertial force generated by the vibration to be parallel to the screen's slope, accelerating the movement of material toward the bottom. Residue that fails to pass through the meshes slides along the inclined surface of the filter screen 6 toward discharge port 16 under the influence of vibration and gravity, where it falls into a collection box 17 below.

[0035] Rotating plate 18, rotatably mounted at discharge port 16, pivots open under the pressure of accumulated material. Once the residue is discharged, rotating plate 18 automatically closes under the force of gravity, preventing leakage of liquid or gas from mixing chamber 5. The filtered extract passes through the vibrating filter screen 6 and into the lower portion of mixing chamber 5, where it mixes with the culture injected through culture feed port 22. The continuous rotation of cam 9 ensures that the vibration frequency of filter screen 6 matches the speed of residue discharge, preventing excessive accumulation of material on the surface of filter screen 6.

[0036] In one embodiment, for the above-mentioned fourth gear 14, the fourth gear 14 is connected to the fifth gear 20 through the third gear belt 19, and the fifth gear 20 is rotatably installed on the mixing box 5. The fifth gear 20 is fixedly installed with a stirring shaft 21, and the stirring shaft 21 is rotatably installed inside the mixing box 5.

[0037] In one embodiment, for the above-mentioned mixing box 5, the bottom of the mixing box 5 is fixedly connected to the fermentation tank 24 through a discharge pipe 23. The mixing box 5 is fixedly installed with support legs 28, and the discharge pipe 23 is provided with a one-way control valve.

[0038] In one embodiment, for the above-mentioned crushing box 1 , a feed opening 25 is fixedly installed on the top of the crushing box 1 , and a cover plate 26 is rotatably installed on the feed opening 25 .

[0039] In one embodiment, for the above-mentioned crushing box 1 , a whetstone 27 is fixedly installed inside the crushing box 1 . There are several whetstones 27 , and the several whetstones 27 all cooperate with the blades on the two crushing rollers 2 .

[0040] The working principle of the fermentation device for a plant extract with medicinal and edible properties proposed in the present invention is that, after the drive motor 4 is activated, it rotates the crushing roller 2 and, through the intermeshing first gear 3, drives the other crushing roller 2 to rotate in the opposite direction. The medicinal and edible plant raw material is fed through a feed port 25 above the crushing chamber 1, and a rotatably mounted cover plate 26 is closed to prevent debris from splashing. Once inside the crushing chamber 1, the raw material is squeezed and cut by the two counter-rotating crushing rollers 2. The blades on the crushing rollers 2 periodically come into contact with multiple grindstones 27 fixed within the chamber, automatically sharpening the blades during the crushing process to maintain their sharpness.

[0041] The crushed material falls into the connected mixing tank 5 below, where it accumulates on the upper surface of the tilted filter screen 6. The output of the drive motor 4 drives the third gear 12 through the second gear 10 and first gear belt 11 of the first transmission mechanism, driving the rotation of the bidirectional threaded rod 7. The opposing threads at each end of the bidirectional threaded rod 7 cause the two extrusion plates 8 to move horizontally toward each other, bidirectionally squeezing the material on the filter screen 6. The extract passes through the mesh and enters the lower portion of the mixing tank 5.

[0042] Third gear 12 drives fourth gear 14 via second gear belt 13 of the second transmission mechanism, driving rotation of rotating shaft 15 and multiple cams 9. The raised ends of cams 9 continuously push against the bottom of inclined filter screen 6, causing it to vibrate at a high frequency. Residue that fails to pass through the filter slides along the inclined screen into discharge port 16, pushes open rotating plate 18, and falls into collection box 17. Rotating plate 18 automatically closes after the residue is discharged.

[0043] The fourth gear 14 drives the fifth gear 20 via the third gear belt 19, driving the agitator shaft 21 to rotate at the bottom of the mixing tank 5, thoroughly mixing the filtered extract with the bacterial strain injected from the bacterial strain inlet 22. The mixed material flows into the fermentation tank 24 through the discharge pipe 23 at the bottom of the mixing tank 5. A one-way control valve in the discharge pipe 23 prevents liquid backflow. The mixing tank 5 is firmly supported by support legs 28. The linkage between the crushing tank 1 and the mixing tank 5 ensures continuous operation from crushing, extrusion, filtration, to stirring. Ultimately, the extract and bacterial strain are mixed and directly enter the fermentation tank 24 for subsequent processing.
