Description

Technical Field

[0001] The invention relates to the technical field of residue recycling and fermentation, and particularly provides a fermentation device for recycling and utilizing residues after ginseng stem and leaf extraction. Background Art

[0002] The residue after extracting ginseng stems and leaves is still rich in active ingredients such as cellulose, hemicellulose, residual saponins (about 2%-5%), polysaccharides, and proteins. Directly discarding it can easily lead to resource waste and environmental pollution. Microbial fermentation technology can effectively degrade the anti-nutritional factors in the residue, transform the saponin structure, degrade pesticide residues, and produce value-added products such as prebiotics.

[0003] After fermentation, the bitter taste in the residue can be eliminated, small molecule organic acids (lactic acid, acetic acid) can be increased, the feeding enthusiasm of aquatic animals can be improved, and probiotics (such as Lactobacillus casei) can colonize the intestines, inhibit pathogenic bacteria, and reduce the incidence of enteritis in aquatic animals.

[0004] During the fermentation of the residue after ginseng stem and leaf extraction, the residue is placed in a conventional fermentation tank and mixed with a fermentation liquid (e.g., a mixture of water and bacterial strains) for fermentation. During the ginseng stem and leaf extraction process, the high-temperature and long-term extraction (e.g., reflux, decoction) significantly destroys the cellulose structure of the stems and leaves, resulting in a loose, finely divided, or even muddy residue. This is especially true if the residue is subjected to post-extraction filtration or centrifugation, which makes the residue even finer. Therefore, during the fermentation process, the residue tends to float on the surface of the fermentation liquid or sink to the bottom of the fermentation tank, resulting in accumulation and difficulty in sufficient contact with the fermentation liquid. Even if the residue is stirred regularly, the limited stirring range results in a low conversion rate of ginsenosides in the residue, which is not conducive to the dissolution of small-molecule active substances (e.g., rare ginsenosides and polysaccharides), and the saponin concentration in the fermentation liquid is greatly reduced.

[0005] If the residue is spread thinly in a fermentation barrel with a larger diameter so that the residue is in full contact with the fermentation liquid during the fermentation process, the fermentation equipment will occupy a larger area, increasing the space cost of the fermentation equipment.

[0006] Therefore, there is an urgent need for a fermentation device for recycling the residue after ginseng stem and leaf extraction that can solve the above problems. Summary of the Invention

[0007] In view of the above problems, an embodiment of the present invention provides a fermentation device for recycling and utilizing residues after ginseng stem and leaf extraction to solve the technical problems in the related art.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 without making creative efforts are within the scope of protection of the present invention.

[0031] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] See Figure 1 、 Figure 2 and Figure 4A fermentation device for recycling residue after ginseng stem and leaf extraction includes: a fermentation barrel 1, a support base, a material container 2 and a capping stirring mechanism 3. The material container 2 is connected to the fermentation barrel 1 by sliding up and down through a locking portion 4. The material container 2 is in a vortex shape with an open top. The inner and outer side walls and the bottom of the vortex of the material container 2 are all provided with evenly arranged water inlet holes, and a vortex chamber 5 is formed in the material container 2.

[0033] See Figure 1 、 Figure 4 and Figure 6 The bottom of the fermentation barrel 1 is funnel-shaped to facilitate the discharge of liquid after fermentation. A barrel cover 6 is installed on the top of the fermentation barrel 1 through a detachable connection. The support base is located on one side of the fermentation barrel 1. The support base is fixedly connected to the barrel cover 6 through a connecting plate that slides up and down. A liquid inlet 60 is installed on the barrel cover 6. The barrel cover 6 is used to seal the top of the fermentation barrel 1. The barrel cover 6 is a hollow structure. The capping stirring mechanism 3 is installed on the barrel cover 6. The capping stirring mechanism 3 is used to stir the residue in the material container 2.

[0034] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 The capping stirring mechanism 3 includes a rotating disk 30 that is rotatably connected to the lower side wall of the barrel cover 6 and penetrates therein. A plurality of stirring parts 31 are installed at the bottom of the rotating disk 30 and are evenly arranged along its circumference. A stirring driving part 32 that drives the rotating disk 30 to rotate intermittently and reciprocatingly is installed in the barrel cover 6. An auxiliary rotating part 33 is also installed in the barrel cover 6. The stirring part 31 includes a movable plate 310 connected to the lower end surface of the rotating disk 30 and sliding along its radial direction. The movable plate 310 is T-shaped. A guide groove that runs through the upper and lower parts and is slidably connected to the movable plate 310 is opened on the rotating disk 30. A return spring 312 is installed between the guide groove and the movable plate 310. The movable plate 310 is rotatably connected to the stirring members 311 that are evenly arranged along its length direction. The stirring members 311 are inserted into the vortex chamber 5.

[0035] When the residue is recycled and fermented, the material container 2 is first inserted and fixed in the fermentation barrel 1 through the locking part 4, and then the residue is placed in the vortex chamber 5 so that the residue is evenly dispersed in the vortex chamber 5 of the material container 2. The stirring member 311 in the capping stirring mechanism 3 is then driven by the barrel cover 6 to be inserted into the vortex chamber 5. Thereafter, the top of the fermentation barrel 1 is sealed and the top of the material container 2 is sealed through the barrel cover 6 to prevent part of the residue from floating upward and overflowing from the material container 2 under the action of the fermentation liquid after the fermentation liquid is added into the fermentation barrel 1 from the liquid inlet 60.

[0036] After the fermentation liquid enters the fermentation barrel 1, it enters the material container 2 through the water inlet and contacts the residue, soaking and fermenting the residue.

[0037] Compared with the traditional method of adding and holding fermentation residue, the vortex-shaped holding method of the holding container 2 immerses the residue in the fermentation liquid in a thinner holding manner, which greatly increases the contact area between the residue and the fermentation liquid. At the same time, it also improves the conversion rate of ginsenosides and bacterial strains in the residue, and does not increase the space occupied by the fermentation equipment.

[0038] Afterwards, the residue in the material holding container 2 is stirred regularly. During stirring, the stirring driving part 32 is started, and the stirring driving part 32 drives the rotating disk 30 to rotate. The rotating disk 30 drives the movable plate 310 and the stirring member 311 to rotate. The stirring member 311 moves along the trajectory of the vortex chamber 5 and drives the movable plate 310 to move radially along the rotating disk 30. At the same time, the stirring member 311 rotates with the assistance of the auxiliary rotating part 33, and performs moving stirring and rotation stirring on the residue in the vortex chamber 5, so that the residue in the vortex chamber 5 is further fully contacted with the fermentation liquid, thereby greatly improving the efficiency of residue fermentation.

[0039] See Figure 4 and Figure 6 The material holding container 2 consists of a vortex cylinder 20 that passes through the upper and lower parts and a vortex base 21 that is slidably connected to the lower end surface of the vortex cylinder 20. The water inlet hole is opened on the side wall of the vortex cylinder 20 and the vortex base 21. The lower end surface of the vortex base 21 is installed with a support frame 22.

[0040] When the residue fermentation is completed, the material container 2 is taken out from the fermentation barrel 1, and then the material container 2 is inverted and the vortex base 21 is pushed by the support frame 22 to push the residue in the material container 2 out, thereby improving the convenience of taking out the residue in the material container 2. At the same time, the support frame 22 can also support the vortex base 21 by contacting with the fermentation barrel 1 when the residue in the material container 2 is fermenting.

[0041] See Figure 4 、 Figure 5 and Figure 7 The locking portion 4 includes a positioning component 40 and an insertion strip 41 installed on the outer wall of the material container 2 through a bracket. The positioning component 40 is used to centrally position the material container 2 and the fermentation barrel 1. The two corners of the lower end of the insertion strip 41 are inclined. The inner wall of the fermentation barrel 1 is installed with supporting seats 42 evenly arranged along its circumference. The insertion strips 41 correspond to the supporting seats 42 one by one. The supporting seat 42 is provided with a slot 43 that passes through from top to bottom. The two opposite side walls at the lower end of the slot 43 are inclined to support the insertion strip 41.

[0042] See Figure 4 and Figure 5The positioning assembly 40 includes a positioning column 401 installed concentrically with the fermentation barrel 1, and a positioning slot is provided on the positioning column 401. A fixing cylinder 402 is installed at the inner end of the vortex of the material holding container 2, and an insert 403 is installed on the inner wall of the fixing cylinder 402 to be plugged into the positioning slot.

[0043] When placing the material container 2, align the positioning slot with the insert 403 up and down, and push the material container 2 downward so that the fixing cylinder 402 is sleeved on the positioning column 401. At this time, the insertion strip 41 moves downward along the corresponding card slot 43 until the bottom of the insertion strip 41 conflicts with the inclined side wall of the card slot 43. The inclined side wall of the card slot 43 supports the insertion strip 41 and the material container 2, so that the material container 2 can be accurately aligned with the capping and stirring mechanism 3 and inserted.

[0044] See Figure 3 The stirring member 311 is composed of a stirring rod 340 rotatably connected to the lower end surface of the movable plate 310 and branch rods 341 installed on the stirring rod 340 and evenly arranged along its circumferential and axial directions. The branch rods 341 are inclined, which expands the rotation stirring range of the stirring member 311. When the stirring member 311 is taken out of the material container 2, the residue can directly slide down along the inclined side wall of the branch rod 341, preventing the residue from being taken out when the stirring member 311 is taken out of the material container 2 later.

[0045] See Figure 2 The auxiliary rotating portion 33 includes a transmission gear 330 fixedly mounted on the stirring member 311, a vortex sheet 331 fixedly mounted on the barrel cover 6 via a connecting frame, and a rack 332 mounted on the vortex sheet 331 that meshes with multiple transmission gears 330. It should be noted that the material container 2 and the vortex sheet 331 are both vortex-shaped with equal spacing.

[0046] See Figure 2 The stirring drive part 32 includes a rack 320 slidably connected to the barrel cover 6 and a conversion gear 321 rotatably connected to the rack 320 for transmission. The conversion gear 321 is rotatably connected to the top of the inner cavity of the barrel cover 6. An arc-shaped rack is fixedly installed on the rotating disk 30. The conversion gear 321 is engaged with the arc-shaped rack for transmission. An electric slider (not shown in the figure) that drives the rack 320 to slide is also installed in the barrel cover 6.

[0047] During the fermentation of the residue, the electric slider is started, and the electric slider drives the rack 1 320 to move, and the meshing transmission between the rack 1 320 and the conversion gear 321 and the conversion gear 321 and the arc-shaped rack is used to drive the rotating disk 30 to rotate. During the rotation of the rotating disk 30, the transmission gear 330 is driven to rotate. The transmission gear 330 is always meshed with the rack 2 332 under the action of the tension of the movable plate 310 pulled by the elastic force of the return spring 312. In the process of rotating with the rotating disk 30, the transmission gear 330 is driven by the meshing transmission with the rack 2 332 to drive the movable plate 310 to move and drive the stirring rod 340 to rotate along the vortex chamber 5, that is, the stirring rod 340 can move and rotate at the same time, thereby increasing the stirring force of the stirring member 311 on the residue in the vortex chamber 5.

[0048] See Figure 1-Figure 7 During specific operation, the material container 2 is first inserted and fixed in the fermentation barrel 1 through the locking portion 4, and then the residue is placed in the vortex chamber 5 so that the residue is evenly dispersed in the vortex chamber 5 of the material container 2. The stirring member 311 in the capping stirring mechanism 3 is then driven by the barrel cover 6 to be inserted into the vortex chamber 5. After that, the top of the fermentation barrel 1 is sealed by the barrel cover 6 and the top of the material container 2 is sealed to prevent part of the residue from floating upward and overflowing from the material container 2 under the action of the fermentation liquid after the fermentation liquid is added into the fermentation barrel 1 from the liquid inlet 60.

[0049] After the fermentation liquid enters the fermentation barrel 1, it enters the material container 2 through the water inlet and contacts the residue, soaking and fermenting the residue. The residue in the material container 2 is then stirred regularly. During stirring, the stirring drive unit 32 is activated, and the stirring drive unit 32 drives the rotating disk 30 to rotate. The rotating disk 30 drives the movable plate 310 and the stirring member 311 to rotate. The stirring member 311 moves along the trajectory of the vortex chamber 5 and drives the movable plate 310 to move along the radial direction of the rotating disk 30. At the same time, the stirring member 311 rotates with the assistance of the auxiliary rotating unit 33 to move and rotate the residue in the vortex chamber 5, so that the residue in the vortex chamber 5 is further fully contacted with the fermentation liquid, greatly improving the efficiency of the residue fermentation.
