Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermentation equipment technology, and in particular to a fermentation tank for vinegar brewing. Background Technology
[0002] Vinegar brewing typically involves two stages: alcoholic fermentation and acetic acid fermentation. During the acetic acid fermentation stage, the raw materials are placed in a fermentation tank for fermentation. Since acetic acid bacteria are aerobic bacteria, an aeration device is installed in the fermentation tank to introduce oxygen. A stirring device is also installed to stir the raw materials. The main function of stirring is to ensure uniform dissolved oxygen, temperature control, and bacterial distribution. In addition, the optimal temperature for acetic acid bacteria is usually between 30-35℃. Temperatures that are too high or too low will affect their activity and acid production efficiency. Therefore, a heat preservation device is installed on the fermentation tank.
[0003] Currently, most heat preservation devices on fermenters (patent document CN219044928U) consist of a jacket installed on the tank body, with an electric heating element installed inside the jacket for heating. However, in practical applications, if the electric heating element inside the jacket malfunctions, the jacket must be removed to repair or replace the heating element, resulting in high maintenance difficulty and low efficiency. Furthermore, the long maintenance time required for the heating element leads to extended downtime of the fermenter, affecting production efficiency. Utility Model Content
[0004] In view of this, this utility model proposes a fermentation tank for vinegar brewing, aiming to solve the problems of high maintenance difficulty and long downtime after the failure of the heat preservation device in the existing fermentation tank.
[0005] The solution provided by this utility model includes:
[0006] A fermentation tank for vinegar brewing, comprising:
[0007] The tank body is provided with an inlet and an outlet;
[0008] A stirring mechanism, comprising a rotating shaft rotatably mounted on the tank, a driver for driving the rotating shaft to rotate, and a stirrer mounted on the rotating shaft;
[0009] The electric heating module includes multiple electric heating modules, each including a first mounting base and an electric heating tube mounted on the first mounting base. The first mounting base is detachably mounted on the top of the tank, and the electric heating tube is inserted into the tank from top to bottom.
[0010] As a further optional solution, a separator sleeve is also included, the separator sleeve comprising a sleeve body, the bottom of the sleeve body being a closed structure, and the top of the sleeve body being an open structure and provided with a second mounting base;
[0011] The second mounting base is disposed on the top of the tank, the sleeve body is disposed inside the tank, and a heat transfer medium is disposed inside the sleeve body;
[0012] The first mounting base of the electric heating module is disposed on the second mounting base, and the electric heating tube is disposed inside the sleeve body.
[0013] As a further optional solution, the top of the tank is provided with a vertical through-hole, and a connecting seat is provided around the through-hole, and the connecting seat is provided with several vertically arranged studs;
[0014] The first mounting base is provided with a first connecting hole, and the second mounting base is provided with a second connecting hole;
[0015] The stud passes through the second connecting hole and the first connecting hole in sequence and is then threadedly connected to a nut to fix the first mounting base and the second mounting base on the top of the tank.
[0016] As a further optional solution, a first sealing gasket is provided between the second mounting base and the connecting base to achieve a sealed connection between the second mounting base and the connecting base;
[0017] A second sealing gasket is provided between the first mounting base and the second mounting base to achieve a sealed connection between the first mounting base and the second mounting base.
[0018] As a further optional solution, the electric heating module is provided with at least three, the rotating shaft of the stirring mechanism is coaxially arranged with the tank body, and the multiple electric heating modules are distributed equidistantly around the rotating shaft in the circumferential direction.
[0019] As a further optional option, the heat transfer medium is water.
[0020] As a further alternative, the agitator may be a turbine agitator, a paddle agitator, or an anchor agitator.
[0021] Compared with the prior art, the fermentation tank for vinegar brewing in this application has at least the following advantages:
[0022] This application abandons the jacketed structure used in conventional fermenters, replacing the original single insulation device with multiple electric heating modules. On one hand, when an electric heating module malfunctions, maintenance personnel can directly remove the corresponding first mounting bracket from the top of the tank, easily extracting the faulty module for repair or replacement, simplifying the maintenance process and reducing its complexity. On the other hand, if one or a few electric heating modules fail, even without immediate replacement, the remaining modules can continue to perform their insulation function, maintaining the basic temperature requirements inside the tank. This avoids prolonged shutdowns of the entire fermenter due to a single electric heating module failure, ensuring production continuity. Attached Figure Description

[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0034] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0035] refer to Figures 1 to 4 This utility model discloses a fermentation tank for vinegar brewing, including a tank body 1, a stirring mechanism 2, and an electric heating module 3. The tank body 1 is provided with an inlet 11 and an outlet 12, both of which are pipe interfaces. The stirring mechanism 2 includes a rotating shaft 21 rotatably mounted on the tank body 1, a driver 22 for driving the rotating shaft 21 to rotate, and a stirrer 23 mounted on the rotating shaft 21. Multiple electric heating modules 3 are provided, each including a first mounting base 32 and an electric heating tube 31 mounted on the first mounting base 32. The first mounting base 32 is detachably mounted on the top of the tank body 1, and the electric heating tube 31 is inserted into the tank body 1 from top to bottom.
[0036] In this embodiment, the heating module 3 is powered on, and by energizing the heating tube 31, the heating tube 31 heats up to maintain the temperature inside the tank 1 within a certain range. Conventionally, a sensor for monitoring temperature is installed inside the tank 1. Thus, the fermenter in this embodiment abandons the jacket structure used in conventional fermenters, replacing the original single insulation device with multiple heating modules 3. On the one hand, when a heating module 3 malfunctions, maintenance personnel can directly remove the corresponding first mounting base 32 from the top of the tank 1, easily removing the faulty heating module 3 for repair or replacement, simplifying the maintenance process and reducing the complexity of maintenance work. On the other hand, if one or a few heating modules 3 malfunction, even without timely replacement with new heating modules 3, the remaining multiple heating modules 3 can still continue to perform their insulation function, maintaining the basic temperature requirements inside the tank 1. This avoids the situation where the entire fermenter is shut down for an extended period due to the failure of a single heating module 3, ensuring the continuity of production.
[0037] It should be noted that if a replacement heating module 3 cannot be found after disassembling the faulty heating module 3, the hole at the original installation location of the heating module 3 can be sealed with a cover (not shown) to maintain the airtightness of the internal space of the tank 1. Of course, before a replacement heating module 3 is found, the power to the faulty heating module 3 can be cut off temporarily without disassembling it, relying on the other normally functioning heating modules 3 to maintain the heat preservation function.
[0038] In some embodiments, such as Figure 2 and Figure 4 As shown, it also includes a separating sleeve 4, which includes a sleeve body 41. The bottom of the sleeve body 41 is a closed structure, and the top of the sleeve body 41 is an open structure and is provided with a second mounting seat 42. The second mounting seat 42 is disposed on the top of the tank 1, and the sleeve body 41 is disposed inside the tank 1. A heat transfer medium is disposed inside the sleeve body 41. The first mounting seat 32 of the electric heating module 3 is disposed on the second mounting seat 42, and the electric heating tube 31 is disposed inside the sleeve body 41.
[0039] In this embodiment, the heating element 31 is isolated from the fermentation raw material in the tank 1 by the partition sleeve 4, so that the heating element 31 will not be contaminated with the fermentation raw material when the heating module 3 is disassembled; and during the disassembly process, the internal space of the tank 1 can still be kept closed due to the obstruction of the partition sleeve 4, so as to avoid external contamination of the fermentation raw material.
[0040] The above-mentioned solutions are specific, such as Figure 4As shown, the top of the tank body 1 is provided with a vertically penetrating insertion hole 13, and a connecting seat 14 is provided around the insertion hole 13. The connecting seat 14 is provided with a plurality of vertically arranged studs 15. The first mounting seat 32 is provided with a first connecting hole 321, and the second mounting seat 42 is provided with a second connecting hole 421. The studs 15 pass through the second connecting hole 421 and the first connecting hole 321 in sequence and are threadedly connected to a nut (not shown) to fix the first mounting seat 32 and the second mounting seat 42 on the top of the tank body 1.
[0041] Preferably, to ensure the sealing between the electric heating module 3, the partition sleeve 4, and the tank 1, a first sealing gasket (not shown) is provided between the second mounting base 42 and the connecting base 14 to achieve a sealed connection between the second mounting base 42 and the connecting base 14; a second sealing gasket (not shown) is provided between the first mounting base 32 and the second mounting base 42 to achieve a sealed connection between the first mounting base 32 and the second mounting base 42.
[0042] Specifically, in the above scheme, water is used as the heat transfer medium. This results in a low-cost, pollution-free heat transfer medium that is easy to replace and replenish.
[0043] Specifically, the structure of the stirrer 23 includes, but is not limited to, turbine stirrer 23, paddle stirrer 23, anchor stirrer 23, etc., which can be set according to actual needs; the driver 22 is a motor. When the driver 22 drives the rotating shaft 21 to rotate, the stirrer 23 rotates synchronously with the rotating shaft 21. The stirrer 23 disturbs the fermentation raw materials inside the tank 1, so that the fermentation raw materials in each area can contact the heating tube 31 or the separating sleeve 4, thereby improving the temperature uniformity inside the tank 1.
[0044] In some embodiments, at least three heating modules 3 are provided, and the rotating shaft 21 of the stirring mechanism 2 is coaxially arranged with the tank body 1. The multiple heating modules 3 are equidistantly distributed around the rotating shaft 21 in the circumferential direction. In this way, the number of heating modules 3 is relatively large, and even if one or a few heating modules 3 fail, the remaining heating modules 3 are sufficient to maintain the heat preservation function.
[0045] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.
[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
