Description

Technical Field

[0001] This utility model belongs to the technical field of lactic acid bacteria fermentation equipment, and in particular relates to a lactic acid bacteria fermentation preservative seasoning device. Background Technology

[0002] In the food processing industry, especially in the condiment production sector, lactic acid bacteria fermentation technology is widely used in the preparation of fermented and preservative condiments such as chicken broth because it imparts a unique flavor to products and has a certain preservative effect. However, current equipment used for chicken broth fermentation still faces many problems in actual production that urgently need to be solved, seriously affecting fermentation efficiency and product quality.

[0003] First, traditional fermenters are mostly single-chamber structures, making it impossible to conduct multiple fermentation experiments or productions with different parameters simultaneously. To achieve differentiated fermentation, multiple independent fermenters are required, increasing equipment costs and occupying significant production space. For example, a lactic acid bacteria fermenter with publication number CN220284037U includes a fermenter body and a cleaning assembly installed within the fermenter body. The cleaning assembly includes a stirring rod installed within the fermenter body, a positioning ring slidably connected to the outer surface of the stirring rod, and a scraper slidably connected to the inner wall of the fermenter body. While this patent can perform lactic acid bacteria fermentation, it only has one independent fermentation area.

[0004] Therefore, in view of the shortcomings of the existing technology, there is an urgent need for a lactic acid bacteria fermentation and preservation seasoning device that can realize independent fermentation in multiple regions. Utility Model Content

[0005] Based on the above background, the purpose of this utility model is to provide a lactic acid bacteria fermentation preservative seasoning device, which effectively avoids cross-contamination during the fermentation process of different batches or types of lactic acid bacteria by setting up multiple independent fermentation zones, thereby improving the purity and quality stability of the fermented products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] As a further limitation of this technical solution, it also includes a stirring module, which includes a rotating shaft. Each of the fermentation areas is provided with a rotating shaft, and the lower end of each rotating shaft is fixedly connected to a stirring blade. The rotating shaft is rotatably connected to the fermentation tank, and the upper end of the rotating shaft is fixedly connected to a second gear. The second gear meshes with the first gear, and the central axis of the first gear is rotatably connected to the fermentation tank. The first gear and the second gear are both arranged inside an outer cover, and the outer cover is fixed to the upper side of the fermentation tank.

[0011] As a further limitation of this technical solution, the center of the first gear is fixedly connected to the output shaft of the motor, the motor is fixed inside the motor cover, and the motor cover is fixed on the upper side of the outer cover.

[0012] As a further limitation of this technical solution, it also includes a metering pump, which is fixed on a base and the fermenter is fixedly connected to the base.

[0015] As a further limitation of this technical solution, a drain valve is provided at the bottom of the fermenter for each fermentation zone.

[0016] This utility model has the following beneficial effects:

[0017] By setting up multiple independent fermentation zones, cross-contamination during the fermentation process of different batches or types of lactic acid bacteria is effectively avoided, thereby improving the purity and quality stability of fermented products.

[0040] See Figures 1-4 A device for fermenting lactic acid bacteria to preserve seasonings.

[0041] Example 1

[0042] A lactic acid bacteria fermentation preservative seasoning device includes a fermentation module 5, which includes a fermentation tank 502. A set of circumferentially evenly arranged partitions 9 are fixedly installed inside the fermentation tank 502, dividing the fermentation tank 502 into several fermentation areas. A feeding channel 501 is provided on the upper side of the fermentation tank 502, and each fermentation area is provided with a feeding channel 501.

[0043] In this embodiment, the fermentation tank 502 is made of stainless steel, which has good corrosion resistance and sealing performance to ensure the stable progress of the fermentation process. Each fermentation zone is independent of each other through the partition 9 to avoid cross-contamination between different fermentation materials. The independent feeding channel 501 facilitates the injection of chicken soup and fermentation materials to be fermented into the fermentation zone.

[0044] The feed channel 501 of the fermenter 502 is fitted with an end cap 4, which is screwed onto the feed channel 501.

[0045] The end cap 4 can fit tightly into the feed channel 501, effectively preventing external impurities from entering the fermentation tank 502 and ensuring a pure fermentation environment. The screw connection makes the installation and removal of the end cap 4 extremely convenient, facilitating the cleaning, maintenance, and addition of fermentation materials by the staff.

[0046] It also includes a sampling module 8, which includes a sampling groove 801, a probe 802 fixed in the sampling groove 801, and the probe 802 fixed to the lower center of the end cap 4. The diameter of the sampling groove 801 is smaller than the inner diameter of the feed channel 501.

[0047] It should be noted that the sampling module 8 can be used to sample the chicken soup in the fermentation area. The staff only needs to open the end cover 4 and use the probe 802, which is fixedly connected to the center of the lower side of the end cover 4, to pull the sampling slot 801 upward from the fermentation area. Since the diameter of the sampling slot 801 is smaller than the inner diameter of the feeding channel 501, the sampling slot 801 can pass smoothly through the feeding channel 501 to obtain the chicken soup sample in the fermentation area for detection and analysis of the fermentation.

[0048] It also includes a stirring module 7, which includes a rotating shaft 704. Each of the fermentation areas is provided with a rotating shaft 704. The lower end of each rotating shaft 704 is fixedly connected to a stirring blade 705. The rotating shaft 704 is rotatably connected to the fermentation tank 502. The upper end of the rotating shaft 704 is fixedly connected to a second gear 703. The second gear 703 meshes with the first gear 702. The central axis of the first gear 702 is rotatably connected to the fermentation tank 502. The first gear 702 and the second gear 703 are both arranged inside an outer cover 701. The outer cover 701 is fixed to the upper side of the fermentation tank 502.

[0049] The output shaft of the motor is fixedly connected to the center of the first gear 702. The motor is fixed inside the motor cover 10, and the motor cover 10 is fixed to the upper side of the outer cover 701.

[0050] In this embodiment, after the motor starts, its output shaft drives the first gear 702 to rotate. Since the first gear 702 meshes with multiple second gears 703, the rotation of the first gear 702 will drive all the second gears 703 to rotate synchronously. The second gears 703 are fixedly connected to the rotating shaft 704. The lower end of the rotating shaft 704 is provided with stirring blades 705 and is rotatably connected inside the fermentation tank 502. Therefore, the rotation of the second gears 703 will drive the rotating shaft 704 and stirring blades 705 to rotate in the fermentation area, thereby fully stirring the chicken soup in the fermentation area, making the fermentation materials evenly mixed, which is conducive to the smooth progress of the fermentation process and improves the fermentation efficiency and fermentation quality.

[0051] The outer cover 701 and the motor cover 10 are designed to protect the gears and motor, preventing damage from external factors.

[0052] It also includes a metering pump 11, which is fixed on a base 6. The fermentation tank 502 is fixedly connected to the base 6. The inlet of the metering pump 11 is fixedly connected to the outlet of the storage tank via a pipeline. The outlet of the metering pump 11 is fixedly connected to an addition pipe 1. The other end of the addition pipe 1 is connected to an inlet pipe 3. The outlet of the inlet pipe 3 corresponds to the feed channel 501. One end of the addition pipe 1 corresponds to the center of the fermentation tank 502.

[0053] In this embodiment, the metering pump 11 can precisely control the amount of liquid drawn from the storage tank. The storage tank can store various additives or nutrient solutions required for fermentation. After the metering pump 11 draws liquid from the outlet of the storage tank through the inlet, it delivers the liquid to the addition pipe 1 through the outlet. The addition pipe 1 guides the liquid to the inlet pipe 3, so that the liquid can enter the feed channel 501 of the fermenter 502. Since one end of the addition pipe 1 corresponds to the center of the fermenter 502 and the outlet of the inlet is directly opposite the feed channel 501, it is convenient to add liquid.

[0054] The other end of the adding tube 1 is fixedly connected to the inlet tube 3 via a connector 2. The connector 2 is rotatably connected to the adding tube 1. The connector 2 is a round tube. The connector 2 is fixedly connected to the inlet tube 3. The connector 2 and the adding tube 1 are sealed together.

[0055] It is worth noting that the rotating connection of connector 2 to add tube 1 can adjust the angle of add tube 1 to a certain extent, enabling operation and addition to different feed channels 501, and facilitating addition to different fermentation zones.

[0056] The bottom of the fermenter 502 is equipped with a drain valve 504 corresponding to each fermentation zone. This facilitates the removal of materials after fermentation.

[0057] Example 2

[0058] This embodiment is a further elaboration based on Embodiment 1. Compared with Embodiment 1, this embodiment also has the following technical features:

[0059] The outer wall of the fermentation tank 502 is provided with an observation window 503 corresponding to each fermentation zone, which facilitates observation of the fermentation status.

[0060] The method of using this utility model is as follows:

[0061] Open the end cap 4 and inject the chicken broth and corresponding fermentation materials to be fermented into each fermentation zone through the independent feeding channel 501. After the injection is completed, tighten the end cap 4 tightly to prevent external impurities from entering.

[0062] When the motor is started, the output shaft of the motor drives the first gear 702 to rotate. The first gear 702 drives multiple second gears 703 that mesh with it to rotate synchronously. The second gears 703 drive the rotating shaft 704 and the stirring blades 705 to rotate in the fermentation area, so as to fully stir the chicken soup and fermentation materials in the fermentation area and make the fermentation materials evenly mixed.

[0063] During the fermentation process, the fermentation status can be observed at any time through the observation windows 503 set on the outer wall of the fermentation tank 502 corresponding to each fermentation area. If it is necessary to sample and analyze the chicken soup in the fermentation area, the staff only needs to open the end cover 4 and use the probe 802 fixedly connected to the center of the lower side of the end cover 4 to pull the sampling slot 801 upward from the fermentation area to obtain the chicken soup sample in the fermentation area. When it is necessary to add the liquid required for fermentation into the fermentation tank 502, the metering pump 11 is started. The metering pump 11 draws a precise amount of liquid from the liquid outlet of the storage tank through the liquid inlet, and then delivers the liquid to the addition pipe 1 through the liquid outlet. The addition pipe 1 guides the liquid to the liquid inlet pipe 3, and finally makes the liquid enter the corresponding feed channel 501 of the fermentation tank 502. Since the connector 2 rotates to connect the addition pipe 1, the angle of the addition pipe 1 can be adjusted as needed to facilitate the addition operation for different fermentation areas.

[0064] After fermentation is complete, open the drain valve 504 at the bottom of fermentation tank 502 corresponding to each fermentation zone to remove the fermented material.

[0065] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
