Description

Technical Field

[0001] This utility model relates to the field of fermentation container technology, specifically a constant temperature fermentation tank. Background Technology

[0002] Pickled cabbage, a traditional fermented vegetable product in my country, is loved by consumers for its unique flavor. A constant-temperature anaerobic environment is crucial for its fermentation process. Traditionally, families make pickled cabbage using jars for fermentation. While this method is simple, it has significant limitations, as the limited capacity of the jars makes it unsuitable for large-scale production.

[0003] With the advancement of industrialization, fermentation tanks are commonly used in industry to achieve large-scale and efficient fermentation of sauerkraut. The specific operation involves placing the sauerkraut in the fermentation tank, adding water and fermentation bacteria, and then sealing it for fermentation. However, during fermentation, the active metabolism of microorganisms such as lactic acid bacteria releases heat, causing the fermentation environment temperature to rise, especially inside the fermentation tank where heat accumulation is more significant. This severely disrupts the constant temperature conditions required for sauerkraut fermentation, greatly affecting the quality and stability of the fermented sauerkraut, and hindering the industrial production of high-quality, efficient sauerkraut. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a constant temperature fermentation tank. The fermentation tank has a support body set inside the tank body, which can easily support the sauerkraut and facilitate layered placement. At the same time, the constant temperature medium flowing inside the support body can be introduced into the sauerkraut, thereby ensuring a constant temperature inside. Furthermore, the support body is rotatably connected, which facilitates the removal and placement of sauerkraut. Fermenting sauerkraut in this fermentation tank not only expands the fermentation scale but also achieves constant temperature fermentation of sauerkraut, ensuring fermentation quality.

[0005] This utility model is implemented as follows: a constant temperature fermentation tank is provided, including a tank body, a support body for placing fermentation materials is rotatably arranged in the tank body, the support body is kept connected to a constant temperature medium fluid pipe on the outer wall of the tank body, a constant temperature medium flows in the support body, and a support pad foot is also provided at the bottom of the support body for maintaining the support body in a horizontal position.

[0006] Preferably, the inner wall of the pool is provided with a connecting pipe, the connecting pipe is in communication with the constant temperature medium fluid pipe, and the support body is sleeved on the outer end of the connecting pipe, which is rotated and in communication with it.

[0007] Preferably, there are multiple supports arranged in layers inside the pool. The rotation positions of adjacent supports are located at both ends of the inner wall of the pool. A connecting pipe and a constant temperature medium fluid pipe are respectively provided on both sides of the rotation position of each support. A support pad is provided at the end of the support away from the rotation position. The support pad contacts the lower support or the bottom of the pool to keep the support horizontal.

[0008] Preferably, the support body is a hollow coil shape, with its two ends connected to the outside of the connecting pipe and maintaining rotation.

[0009] Preferably, the support body is a hollow rectangular frame with both ends on one side extending outward and maintaining communication and rotation with the end of the connecting pipe, and several support rods are evenly arranged on the inner end of the other side of the support body. The support rods connect the two sides of the inner end of the rectangular frame, and a plug is provided inside the support body at the position corresponding to the connecting pipe.

[0010] Preferably, the side wall of the pool is also provided with an inlet pipe and an outlet pipe, both of which are equipped with valves. An exhaust pipe is also provided at the top of the side wall of the pool, and a one-way valve is provided on the exhaust pipe.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. This fermentation tank features a support structure with a flowable, temperature-controlled medium channel within it. This allows for layering of the sauerkraut during fermentation, ensuring a continuous and stable flow of the temperature-controlled medium. This effectively prevents temperature fluctuations caused by heat production from lactic acid bacteria and other microorganisms, and particularly ensures a constant temperature within the fermentation tank. This significantly improves the quality and stability of the sauerkraut fermentation process.

[0013] 2. The support structure features a rotating connection, making the handling of sauerkraut extremely convenient. After fermentation, operators can easily rotate the support structure to quickly remove the sauerkraut. Compared to the complex handling methods in traditional fermentation tanks, this significantly saves labor and time costs, improving production efficiency. Furthermore, when placing sauerkraut for a new round of fermentation, the rotating connection also allows operators to accurately place the sauerkraut in the appropriate position, further enhancing the smoothness of the overall production process.

[0023] As described in the background section, existing household pickling jars cannot meet the requirements for large-scale sauerkraut fermentation. To expand the scale, industrial fermentation tanks are commonly used to ferment sauerkraut. During fermentation, sauerkraut is piled up in the fermentation tank, and then water and fermentation bacteria are introduced for fermentation. However, sauerkraut generates heat during fermentation, which causes the internal temperature of the piled sauerkraut to rise, while the heat on the outside of the sauerkraut dissipates in time, resulting in uneven temperature and affecting the fermentation quality.

[0024] Based on the above reasons, in order to solve the above problems, this utility model provides the following technical solution:

[0025] Example 1:

[0026] Please see the appendix Figure 1~Appendix Figure 5 A constant temperature fermentation tank includes a tank body 1, a support body 2 for placing fermentation material is rotatably disposed inside the tank body 1, the support body 2 is connected to a constant temperature medium fluid pipe 3 on the outer wall of the tank body 1, a constant temperature medium flows inside the support body 2, and a support pad 7 is also provided at the bottom of the support body 2 for maintaining the support body 2 in a horizontal position.

[0027] In this embodiment, please refer carefully to the appendix. Figure 5 The inner wall of the pool body 1 is provided with a connecting pipe 9, which is in communication with the constant temperature medium fluid pipe 3. The support body 2 is sleeved on the outer end of the connecting pipe 9, which is rotated and in communication with it.

[0028] In this embodiment, please refer to the appendix. Figure 3 and attached Figure 4 The support body 2 has multiple components (only 2 are shown in the figure for ease of illustration) and is arranged in layers inside the pool body 1. The rotation positions of adjacent support bodies 2 are located at both ends of the inner wall of the pool body 1. A connecting pipe 9 and a constant temperature medium fluid pipe 3 are respectively provided on both sides of the rotation position of each support body 2. A support pad 7 is provided at the end of the support body 2 away from the rotation position. The support body 2 is kept horizontal by contacting the lower support body 2 or the bottom of the pool body 1 with the support pad 7.

[0029] In this embodiment, the side wall of the pool body 1 is also provided with an inlet pipe 4 and a drain pipe 6, both of which are equipped with valves. An exhaust pipe 5 is also provided at the top of the side wall of the pool body 1, and a one-way valve is provided on the exhaust pipe 5.

[0030] In this fermentation tank, the sauerkraut is first placed at the bottom of the tank body 1 and leveled. Then, the bottom support 2 is rotated to a horizontal position, and sauerkraut is placed on top of the support 2. After that, the sauerkraut on the upper support 2 is placed in sequence. After all the sauerkraut is placed, water is injected into the tank through the water inlet pipe 4 to keep the sauerkraut submerged in water. Fermentation bacteria are then added. Finally, the top of the tank body 1 is sealed with a sealing membrane to achieve anaerobic fermentation. During the fermentation process, a constant temperature medium is discharged into the support 2 through the constant temperature medium fluid pipe 3 and the connecting pipe 9. The constant temperature medium flows inside the support 2 and cools down the heat dissipated inside through heat conduction, thereby achieving constant temperature fermentation. Furthermore, the flow of the constant temperature medium inside the support 2 prevents the constant temperature medium from directly contacting the sauerkraut, thus achieving anaerobic fermentation of the sauerkraut.

[0031] Example 2:

[0032] Based on Example 1, in order to facilitate the support of sauerkraut and allow the constant temperature medium to flow evenly inside the sauerkraut, a feasible solution is provided here. The support body 2 is a hollow coil shape, with its two ends connected to the outside of the connecting pipe 9 and kept rotating.

[0033] Example 3:

[0034] Please see the appendix Figure 1 and attached Figure 5 Based on Example 1, in order to facilitate the support of the sauerkraut and allow the constant temperature medium to flow evenly inside the sauerkraut, another feasible solution is provided. The support body 2 is a hollow rectangular frame with both ends on one side extending outward and maintaining communication and rotation with the ends of the connecting pipe 9. Several support rods are evenly arranged on the inner end of the other side of the support body 2, and the support rods connect the two sides of the inner end of the rectangular frame. A plug 8 is provided inside the support body 2 at the corresponding position of the connecting pipe 9.

[0035] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
