Description

Technical Field

[0001] The present invention relates to a production fermentation device, specifically a microbial fermentation device for condiment production, belonging to the technical field of condiment production and processing. Background Art

[0002] As an auxiliary food that can enhance the color, aroma, and taste of dishes, promote appetite, and be beneficial to human health, condiments play an important role in the food industry. Condiment fermentation mainly utilizes the metabolic activities of microorganisms (such as bacteria, fungi, etc.) to convert the components in raw materials into products with specific flavors, colors, and textures. During the condiment processing process, the fermentation device plays a key role.

[0003] After retrieval, Chinese Patent No. CN220335177U discloses a fermenting device for flavoring sauce. The stirring shaft is driven to rotate by a driving motor, and a spring connection is adopted between the mounting block and the stirring frame. On the one hand, it prevents the connecting rod from disengaging from the sliding hole. On the other hand, it ensures that during the discharging process, if there is solid adhesion in the fermentation inner cylinder, it will not cause the mounting block to be stuck and affect the continuous rotation of the stirring shaft; and the bristles implanted on the cleaning plate brush the fermentation inner cylinder to prevent the flavoring sauce from adhering to the inner wall and causing waste.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Embodiment 1:

[0032] Refer to Figures 1-7 , a microbial fermentation device for the production of seasonings, including a fermentation tank 1. The fermentation tank 1 is cylindrically arranged and is used for fermenting seasoning raw materials by culturing microorganisms. Inside the fermentation tank 1, there are a stirring component 3, an auxiliary filtration component 4, and an adjustment component 5. The stirring component 3 is used for fully stirring and mixing the seasoning raw materials and fermentation broth that need to be fermented to improve the fermentation efficiency. Inside the fermentation tank 1, a vertical stirring plate 304 and a spiral stirring blade 303 are sequentially arranged from top to bottom.

[0033] At the inner bottom end of the fermentation tank 1, there is an inclined bottom cavity 102. The inclined bottom cavity 102 is in the shape of a frustum of a cone with a wider upper part and a narrower lower part. In the middle of the top end of the fermentation tank 1, there is a driving motor 301. The execution end of the driving motor 301 is provided with a rotating rod 302. A vertical stirring plate 304 is arranged at the top end of the rotating rod 302. Two sets of spiral stirring blades 303 are arranged in the middle and at the bottom end of the rotating rod 302. The vertical stirring plate 304 is arranged in a rectangular shape. At one end of the vertical stirring plate 304 far from the rotating rod 302, there is a side scraping plate 305. The bottom end of the side scraping plate 305 is located at the top end of the inclined bottom cavity 102, and the side of the side scraping plate 305 far from the vertical stirring plate 304 is tangent to the inner wall of the fermentation tank 1.

[0034] In this embodiment, it should be noted that: when fermenting condiments, microbial cultivation is required, and during the cultivation process, stirring is needed to fully mix it with the condiment raw materials.

[0035] Two stirring structures are arranged inside the fermentation tank 1. The vertical stirring plate 304 is arranged at the top end of the fermentation tank. With its strong stirring effect, the vertical stirring plate 304 can more effectively overcome the viscosity of the materials, realize mixing and fermentation. Moreover, the side scraping plate 305 connected to the vertical stirring plate 304 can scrape the raw materials attached to the inner wall of the fermentation tank 1. On the one hand, it avoids the attachment of raw materials to the inner wall of the fermentation tank 1, and on the other hand, it improves the stirring and mixing intensity; while the spiral stirring blades 303 can push the condiments to flow axially and radially along the spiral direction when rotating, forming a large-scale overall circulating flow and improving the mixing effect.

[0036] The combined use of the vertical stirring plate 304 and the spiral stirring blades 303 enables both shear force and stirring and mixing intensity to be achieved, improving the fermentation efficiency.

[0037] The inclined bottom cavity 102 at the inner bottom end of the fermentation tank 1 enables the condiments to flow better downward along the inclined surface when filtering the condiments, avoiding waste of raw materials.

[0038] Embodiment Two:

[0039] Different from Embodiment One, referring to Figures 1-7 , this embodiment also has the following further content: A filter plate 503 is arranged at the bottom end of the fermentation tank 1. The auxiliary filtering assembly 4 is used to press-filter the fermented condiments so that the fermented condiments can better pass through the filter plate 503. At a position near the filter plate 503 at the bottom end of the fermentation tank 1, there is a cross bar 408. A circular frame 409 and a silica gel scraping plate 410 are arranged on the cross bar 408. The adjusting assembly 5 is used to seal and open the bottom end of the fermentation tank 1. An execution motor 501 is arranged inside the bottom end of the fermentation tank 1. The execution end of the execution motor 501 is provided with a rotating disk 502. The filter plate 503 is arranged on the rotating disk 502.

[0040] One end of the rotating rod 302 close to the driving motor 301 is provided with a clamping block 401. Inside the outer part of the fermentation tank 1, there is a connecting block 402. Between the connecting block 402 and the clamping block 401, there is a first conveyor belt 403. At the bottom end of the connecting block 402, there is a rotating rod 404. At the bottom end of the rotating rod 404, there is a fixed rod 405. The fixed rod 405 is not connected to the rotating rod 404. In the middle of the outer side of the fixed rod 405, there is a first bevel gear 406 sleeved. On the side of the first bevel gear 406 close to the inclined bottom cavity 102, there is a second bevel gear 407. The second bevel gear 407 is connected with a cross bar 408.

[0041] The rotating disk 502 is circularly arranged. At the bottom end in the middle of the rotating disk 502, there is a connecting rod 514. The connecting rod 514 is connected with the execution end of the execution motor 501. On one side of the bottom end of the fermentation tank 1 close to the rotating rod 404, there is a docking block 506. Between the middle of the connecting rod 514 and the docking block 506, there is a second conveyor belt 505. At the top end of the docking block 506, there is a sleeve 507. Inside the sleeve 507 at the top end of the docking block 506, there is a lead screw 508. On the lead screw 508, there is a lifting plate 509. On the top end of the rotating disk 502 close to one side of the filter plate 503, there is an arc-shaped groove 504. In the middle of the arc-shaped groove 504, there is a lifting rod 511. At the top end and the bottom end of the lifting rod 511, there are respectively a limit clamping rod 512 and a limit rod 510. The lifting rod 511 is connected with the lifting plate 509 at a position close to the bottom end.

[0042] In this embodiment, it should be noted that: after condiments such as soy sauce and vinegar are fermented, they still need to be filtered.

[0043] By default, when using the fermentation tank 1 for filtration, at this time, the execution motor 501 drives the rotating disk 502 to rotate, so that the positions of the rotating disk 502 other than the filter plate 503 and the arc-shaped groove 504 rotate to the bottom end of the fermentation tank 1. At this time, the fermentation tank 1 is in a closed state for fermentation.

[0044] At this time, the lifting plate 509 drives the lifting rod 511 to approach the position of the limit rod 510. At this time, the limit clamping rod 512 is not connected to the limit groove 513. When the driving motor 301 is started, it can only drive the rotating rod 302, the spiral stirring blade 303, the vertical stirring plate 304 and the side scraping plate 305 to rotate for stirring and mixing fermentation.

[0045] When it is necessary to filter the condiments, the execution motor 501 of the adjusting assembly 5 is started and rotates in the reverse direction, realizing the rotation of the rotating disk 502 on the inner wall of the bottom end of the fermentation tank 1, and rotating the filter plate 503 from the inside of the bottom end of the fermentation tank 1 to the bottom end of the fermentation tank 1. At this time, the bottom end of the fermentation tank 1 is in an open state.

[0046] Turn off the drive motor 301, and set the program for the state when the drive motor 301 is turned off through the PLC controller, so that the position of the limit groove 513 aligns with the limit clamping rod 512 when the drive motor 301 is turned off.

[0047] Start the actuating motor 501. At this time, the actuating motor 501 rotates in the reverse direction, the second conveyor belt 505 rotates, drives the docking block 506 to rotate, that is, drives the lead screw 508 connected to the docking block 506 to rotate. The lifting plate 509 connected to the nut of the lead screw 508 moves upward under the limit of the sleeve 507, drives the lifting rod 511 to move out of the limit rod 510, and makes the limit clamping rod 512 move in the fixed rod 405 until it is connected to the limit groove 513 at the bottom end of the rotating rod 404. At this time, the drive motor 301 is started, the rotating rod 302 rotates, the clamping block 401 located on the rotating rod 302 rotates, and then drives the first conveyor belt 403 to rotate, realizing the rotation of the rotating rod 404, and then driving the rotation of the fixed rod 405, the first bevel gear 406, the second bevel gear 407 meshing with the first bevel gear 406, the cross bar 408, the circular frame 409 and the silica gel scraper 410, so that the silica gel scraper 410 rotates and repeatedly presses against the surface of the filter plate 503, sweeping away the sediment formed by fermentation, and avoiding the accumulation and blockage of sediment on the filter plate 503 when filtering seasonings.

[0048] Embodiment Three:

[0049] Refer to Figures 1-2 In this embodiment, compared with Embodiment One and Embodiment Two: the limit clamping rod 512 penetrates through the fixed rod 405, the lifting rod 511 is movably clamped with the limit rod 510, the limit clamping rod 512 is movably clamped with the fixed rod 405, the limit clamping rod 512 is arranged in a straight shape, the bottom end of the rotating rod 404 is provided with a limit groove 513, the shape and size of the limit groove 513 are the same as those of the limit clamping rod 512, the lifting plate 509 is connected to the nut of the lead screw 508, and the first bevel gear 406 meshes with the second bevel gear 407.

[0050] There is an interlayer cavity 2 in the middle of the outer wall of the fermentation tank 1. A spiral cooling water pipe 201 is arranged inside the interlayer cavity 2. One side of the top end of the fermentation tank 1 is provided with a feeding port 101.

[0051] In this embodiment, it should be noted that: the fermentation tank 1 is equipped with a temperature sensor, a pH sensor, a dissolved oxygen sensor, and a liquid level sensor. When it is detected that the temperature inside the fermentation tank 1 is too high, the cooling medium flows in the spiral cooling water pipe 201, exchanges heat with the fermentation liquid in the fermentation tank 1, and takes away the heat to achieve cooling. The bottom end of the cooling water pipe 201 is the water inlet, and the top end is the water outlet.
