Description

Technical Field

[0001] This utility model relates to the field of production technology, and in particular to a fermentation device for producing red sour soup. Background Technology

[0002] Red sour soup, a traditional fermented food in my country, relies heavily on a stable anaerobic fermentation environment for its unique flavor and quality. In the industrial production of red sour soup, it is crucial to regularly monitor the physicochemical indicators of the materials in the fermentation tank (such as acidity, microbial growth, and flavor compound formation), as this directly relates to product quality control and the determination of the fermentation endpoint.

[0003] However, traditional sampling methods usually require opening the sampling port or manhole cover of the fermentation tank. This is not only cumbersome, but more seriously, each opening inevitably introduces a large amount of outside air (oxygen) and potential contaminants. The intrusion of oxygen can disrupt or even interrupt the critical anaerobic fermentation process, leading to a decrease in the activity of beneficial bacteria or changes in metabolic pathways. At the same time, it creates conditions for the growth of harmful aerobic microorganisms. Contamination directly threatens the safety and flavor purity of the product, and may lead to spoilage or serious fluctuations in quality of batches of products. Utility Model Content

[0004] In view of the above situation and in order to make up for the shortcomings of the existing technology, the purpose of this utility model is to provide a fermentation device for the production of red sour soup, which effectively solves the problem of easy contamination when sampling in existing red sour soup fermentation devices.

[0005] The technical solution is as follows: This utility model includes a fermenter, with a sealing cover detachably connected to the upper end of the fermenter, a discharge valve at the lower end of the fermenter, a piston cylinder with a left-right axial direction at the right end of the fermenter, a sampling tube inserted into the fermenter at the left end of the piston cylinder, an L-shaped conveying pipe located on the right side of the fermenter inside the piston cylinder, a piston plate that can move left and right coaxially inside the fermenter, a first one-way valve with its opening facing the piston plate inside the sampling tube, and a second one-way valve with its opening facing downward inside the conveying pipe.

[0006] Preferably, the piston plate has a pull column coaxially provided at the right end, and the right end of the pull column extends out of the piston cylinder and is provided with a pull plate.

[0007] Preferably, the fermenter is provided with a connecting pipe, and a pressure gauge is provided at the free end of the connecting pipe.

[0008] Preferably, the fermenter is connected to the sealing cap by bolts.

[0009] Preferably, the fermenter has a support plate located below the piston cylinder at the right end, and a collection box is detachably connected to the upper end of the support plate.

[0010] Preferably, the carrier plate has a limiting hole, and the lower end of the collection box is provided with a limiting post that can be inserted into the limiting hole.

[0011] Preferably, the fermenter is provided with multiple support legs at its lower end.

[0012] Compared with the prior art, the beneficial effects of this utility model are: it can realize the coordinated work of the piston plate moving coaxially inside the fermenter with the right-end piston cylinder, sampling tube and L-shaped delivery tube. With the cooperation of the first one-way valve and the second one-way valve with specific opening directions, the operator only needs to push and pull the plate outside the fermenter to drive the piston plate to move left and right, thereby creating a negative pressure inside the fermenter to draw in the fermentation liquid sample, and then using positive pressure to discharge the sample through the delivery tube in a directional manner. This closed sampling mechanism completely avoids the risk of bacterial contamination and the destruction of the fermentation environment (such as anaerobic conditions) caused by traditional open sampling, and greatly ensures the purity of the fermentation product and the stability of the process.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the implementations of the base model disclosed below.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Depend on Figures 1 to 5 The present invention includes a fermenter 1, a sealing cover 2 detachably connected to the upper end of the fermenter 1, a discharge valve 3 at the lower end of the fermenter 1, a piston cylinder 4 with a left-right axial direction at the right end of the fermenter 1, a sampling tube 5 inserted into the fermenter 1 at the left end of the piston cylinder 4, an L-shaped conveying pipe 6 located to the right of the fermenter 1 inside the piston cylinder 4, a piston plate 7 that can move left and right coaxially inside the fermenter 1, a first one-way valve 8 with its opening facing the piston plate 7 inside the sampling tube 5, and a second one-way valve 9 with its opening facing downward inside the conveying pipe 6.

[0024] To facilitate the movement of the piston plate 7, a pull column 10 is coaxially provided at the right end of the piston plate 7. The right end of the pull column 10 extends out of the piston cylinder 4 and is provided with a pull plate 11.

[0025] To facilitate the detection of pressure inside the fermenter 1, the fermenter 1 is provided with a connecting pipe 12, and a pressure gauge 13 is provided at the free end of the connecting pipe 12.

[0026] To allow the fermenter 1 to be detached from the sealing cover 2, the fermenter 1 is connected to the sealing cover 2 by bolts.

[0027] To facilitate sample collection, the right end of the fermenter 1 is provided with a support plate 14 located below the piston cylinder 4, and a collection box 15 is detachably connected to the upper end of the support plate 14.

[0028] In order to detach the collection box 15 from the support plate 14, the support plate 14 is provided with a limiting hole, and the lower end of the collection box 15 is provided with a limiting post 16 that can be inserted into the limiting hole.

[0029] For ease of support, the fermentation tank 1 is provided with multiple support legs at its lower end.

[0030] When using this utility model, firstly, the operator must ensure that the sealing cover 2 at the top of the fermentation tank 1 is tightly connected by bolts to ensure the sealing of the fermentation tank 1. After fermentation begins, the pressure change inside the fermentation tank 1 can be monitored in real time by the pressure gauge 13 connected to the fermentation tank 1. When it is necessary to extract the fermentation liquid sample, the operator stands on the right side of the fermentation tank 1, holds the pull plate 11, and steadily pulls the pull column 10 to the right.

[0031] Pull column 10 drives the coaxial piston plate 7 inside fermenter 1 to move to the right. As the piston plate 7 moves to the right, a negative pressure is formed in the left end area of ​​sampling tube 5. At this time, the first one-way valve 8 inside sampling tube 5 opens automatically under the action of pressure difference, and the liquid sample in fermenter 1 is sucked into sampling tube 5. After the sampling is completed, the operator releases pull plate 11 and then pushes pull plate 11 to the left. Pushing pull plate 11 causes pull column 10 and piston plate 7 to move to the left, generating pressure on the liquid in sampling tube 5 and delivery tube 6. This pressure causes the first one-way valve 8 inside sampling tube 5 to close automatically to prevent sample backflow.

[0032] Simultaneously, pressure is applied to the second one-way valve 9 inside the L-shaped delivery pipe 6, pushing the second one-way valve 9 to open. The sample liquid is then forced into the delivery pipe 6 and flows downward along its L-shaped structure, eventually exiting through the lower opening of the delivery pipe 6. Since a support plate 14 is provided at the right end of the fermenter 1 and below the piston cylinder 4, and a collection box 15 is placed on the support plate 14 (the collection box 15 is secured by being vertically inserted into the limiting hole of the support plate 14 through the limiting post 16 at its lower end), the falling sample liquid is accurately dripped into or flows into the collection box 15, completing the aseptic collection of the sample. After sampling, a new collection box 15 can be replaced for the next use.

[0033] Compared with the prior art, the beneficial effects of this utility model are as follows: The fermenter, piston cylinder, and piston plate provided enable the piston plate, which moves coaxially within the fermenter, to work in coordination with the right-end piston cylinder, sampling tube, and L-shaped delivery tube. Combined with a first and second one-way valve with specific opening directions, the operator only needs to push and pull a plate outside the fermenter to drive the piston plate to move left and right, thereby creating negative pressure within the fermenter to draw in the fermentation liquid sample. The sample is then discharged directionally through the delivery tube via positive pressure. This closed sampling mechanism completely avoids the risk of contamination and damage to the fermentation environment (such as anaerobic conditions) caused by traditional open-top sampling, greatly ensuring the purity and process stability of the fermentation product. It is also simple to operate, saving time and effort. This structure is simple, novel in design, convenient to use, and highly practical.

[0034] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model.

[0035] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
