Description

Technical Field

[0001] The utility model belongs to the technical field of fermentation of bean paste, and in particular relates to a constant temperature fermentation tank for processing torreya grandis bean paste. Background Art

[0002] The bean paste fermentation tank is a tank for storing fermented soybeans. The types of fermentation tanks required vary depending on the manufacturer's region. For example, in the southern region close to the equator, the temperature difference does not change much throughout the year, so the structure of such a fermentation tank is a simple tank body. However, in the north, the temperature difference is large throughout the year, especially in the long winter, and the soybean fermentation period is about 6 months, so the temperature of the fermentation tank needs to be controlled, which requires a constant temperature fermentation tank.

[0003] At present, when processing bean paste, traditional fermentation tanks mainly rely on the stirring shaft to increase the contact area between the raw materials and the air, so as to achieve uniform heating. However, since the stirring flow direction of the stirring shaft is relatively fixed, it is easy to form the so-called "stirring dead corner", that is, some raw material areas are difficult to be fully stirred and heated because they are difficult to reach. This not only affects the comprehensiveness and efficiency of stirring, but also increases the risk of uneven fermentation of raw materials.

[0004] In addition, in the subsequent static stage of the fermentation tank, due to the lack of an effective temperature regulation mechanism, it is difficult to keep the temperature of each area of ​​the bean paste constant, which may not only affect the fermentation effect of the bean paste, but also lead to unstable product quality.

[0005] Therefore, it is very necessary to invent a constant temperature fermentation tank for processing torreya grandis bean paste. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a constant temperature fermentation tank for processing torreya grandis bean paste, comprising a fermentation kettle body, a kettle cover, a constant temperature circulation system, a steam heating cover, a fixed seat, a stirring shaft and a driving component, wherein the fermentation kettle body is fixedly installed with the kettle cover, the fermentation kettle body is connected to the constant temperature circulation system, the steam heating cover is fixedly installed outside the fermentation kettle body, and the fixed seat is fixedly installed on the steam heating cover; the stirring shaft inside the fermentation kettle body is fixedly connected to the output end of the driving component, and the driving component is installed outside the kettle cover;

[0007] The constant temperature circulation system includes a centralized pipeline, branch pipelines, pipe openings, a constant temperature heating pipeline and a circulation pumping device. The centralized pipeline is fixedly installed inside the fermentation kettle body; a plurality of branch pipelines are fixedly installed on the centralized pipeline, and each branch pipeline is provided with a plurality of pipe openings; the centralized pipeline is connected with the constant temperature heating pipeline, and the constant temperature heating pipeline is connected with the fermentation kettle body through the circulation pumping device.

[0008] Preferably, the central pipe is a circular pipe, the central pipe and the branch pipe are located outside the stirring shaft and do not affect the rotational movement of the stirring shaft, and the branch pipe is located around the inner wall of the fermentation tank.

[0009] Preferably, the plurality of pipe openings provided on the branch pipe are located at different heights, and the temperature sensor fixedly installed on the branch pipe is located on one side of the pipe opening.

[0010] Preferably, the steam heating hood is provided with a steam inlet pipe opening and an outlet pipe opening, the constant temperature heating pipe is located on the inner side of the steam heating hood 4, the constant temperature heating pipe is a spiral pipe, and there is a distance between the constant temperature heating pipe and the fermentation kettle body to allow thermal expansion.

[0011] Preferably, the circulating pumping device is arranged on the lower side of the fermentation kettle body, and the circulating pumping device is a high temperature resistant and waterproof pumping device, and the circulating pumping device is used to pump the material inside the fermentation kettle body into the constant temperature heating pipe.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model ingeniously introduces a constant temperature circulation system, which, combined with the stirring shaft, not only significantly improves the heating efficiency and comprehensiveness of the bean paste raw materials, but also effectively controls the temperature distribution of the raw materials inside the fermentation kettle. During the stirring and heating process, the stirring shaft ensures the basic mixing of the raw materials, while the constant temperature circulation system is responsible for pumping the bean paste raw materials out of the fermentation kettle and guiding them into the constant temperature heating pipe in the steam heating hood. Through this process, the raw materials are fully in contact with the steam in the constant temperature heating pipe, thereby achieving comprehensiveness and high efficiency of heating.

[0014] What is more worth mentioning is that the constant temperature circulation system is equipped with a temperature sensor that can monitor the temperature of each area in real time. Once the temperature is found to be low in a certain place, the system will respond quickly and pump the raw materials in that area into the constant temperature heating pipe for reheating to ensure that the temperature of the raw materials in the entire fermentation kettle is uniform. This precise temperature control mechanism not only improves the fermentation effect of bean paste, but also ensures the stability and consistency of product quality.

[0022] As attached Figure 1 To Attachment Figure 3 As shown:

[0023] The utility model provides a constant temperature fermentation tank for processing Chinese torreya grandis bean paste, comprising a fermentation kettle body 1, a kettle cover 2, a constant temperature circulation system 3, a steam heating cover 4, a fixing seat 5, a stirring shaft 6 and a driving component 7. The kettle cover 2 is fixedly installed on the fermentation kettle body 1, the fermentation kettle body 1 is connected to the constant temperature circulation system 3, the steam heating cover 4 is fixedly installed outside the fermentation kettle body 1, and the fixing seat 5 is fixedly installed on the steam heating cover 4; the stirring shaft 6 inside the fermentation kettle body 1 is fixedly connected to the output end of the driving component 7, and the driving component 7 is installed on the outside of the kettle cover 2.

[0024] The constant temperature circulation system 3 includes a central pipeline 31, a branch pipeline 32, a nozzle 33, a constant temperature heating pipeline 34 and a circulation pumping device 35. The central pipeline 31 is fixedly installed inside the fermentation kettle body 1; a plurality of branch pipelines 32 are fixedly installed on the central pipeline 31, and each branch pipeline 32 is provided with a plurality of nozzles 33; the central pipeline 31 is connected with the constant temperature heating pipeline 34, and the constant temperature heating pipeline 34 is connected with the fermentation kettle body 1 through the circulation pumping device 35. The constant temperature circulation system 3 is combined with the stirring shaft 6, which not only significantly improves the heating efficiency and comprehensiveness of the bean paste raw materials, but also effectively controls the temperature distribution of the raw materials inside the fermentation kettle body 1.

[0025] Embodiment 1:

[0026] Specifically, the central pipeline 31 is a circular pipeline. The central pipeline 31 and the branch pipeline 32 are located outside the stirring shaft 6 and do not affect the rotation of the stirring shaft 6. The branch pipeline 32 is a branch of the central pipeline 31 and is evenly distributed around the inner wall of the fermentation tank body 1. These branch pipelines 32 connect the central pipeline 31 and the fermentation tank body 1, and are used to pump the bean paste raw materials that need to be heated out of the fermentation tank body 1 and transport them to the constant temperature heating pipeline 34 for heating. When the temperature of the raw materials in a certain area needs to be adjusted, the branch pipeline 32 at the corresponding position will be started, and the raw materials in the area will be pumped into the constant temperature heating pipeline 34, and then re-injected into the fermentation tank body 1 after heating, thereby achieving precise control of the raw material temperature.

[0027] Specifically, the several nozzles 33 provided on the branch pipe 32 are located at different heights, and the nozzles 33 are equipped with electromagnetic valves, so that the bean paste raw materials can be pumped out and pumped in at different heights as needed. In order to achieve accurate control of the temperature of the raw materials, temperature sensors are fixedly installed on the branch pipe 32, and these sensors are located on one side of the nozzles 33. By real-time monitoring of the temperature of the area near the nozzles 33, the system can accurately determine the temperature state of the raw materials and start the corresponding nozzles 33 for heating or mixing operations as needed.

[0028] Furthermore, when the system detects that the temperature in a certain area is low, the nozzle 33 near the area will be opened, and the raw material will be pumped into the constant temperature heating pipe 34 for heating through the circulation pumping device 35. The heated raw material is then re-injected into the fermentation tank body 1 through other nozzles 33, thereby achieving uniform regulation and control of the raw material temperature.

[0029] Specifically, the steam heating cover 4 is provided with a steam inlet and outlet, and the constant temperature heating pipe 34 is located inside the steam heating cover 4. The constant temperature heating pipe 34 is a spiral pipe. The design of the spiral pipe increases the contact area between the raw material and the steam, thereby improving the heating efficiency. At the same time, the spiral structure also helps the flow and mixing of the raw materials in the pipe, further ensuring the uniformity of heating. A certain distance is maintained between the constant temperature heating pipe 34 and the fermentation kettle body 1, and this distance allows the thermal expansion generated by the pipe during the heating process. This design avoids deformation or damage of the pipe due to thermal expansion, and ensures the stability and safety of the entire system.

[0030] Specifically, the circulating pumping device 35 is arranged on the lower side of the fermentation kettle body 1. The circulating pumping device 35 is a high temperature resistant and waterproof pumping device. The circulating pumping device 35 is used to pump the material inside the fermentation kettle body 1 into the constant temperature heating pipe 34.

[0031] Embodiment 2:

[0032] First, the raw material of Torreya grandis bean paste to be fermented is injected through the feed nozzle of the kettle cover 2, and the steam generated by the steam generator is injected into the steam heating chamber formed between the fermentation kettle body 1 and the steam heating cover 4. At this time, the driving component 7 and the circulating pumping device 35 are turned on, and the stirring shaft 6 stirs the raw material. The raw material is pumped into the constant temperature heating pipe 34 by the circulating pumping device 35. The spiral constant temperature heating pipe 34 can increase the contact area between the raw material and the steam, which can not only effectively improve the heating efficiency of the raw material, but also improve its mixing efficiency to a certain extent. The raw material can be re-injected into the fermentation kettle body 1 through the nozzles 33 at different heights. On the contrary, the reverse sequence can be achieved. During the static fermentation process, or when detecting the temperature between the various regions of the raw material, when the temperature of a certain area is low, the nozzle 33 located in the area opens the solenoid valve, and the circulating pumping device 35 pumps the raw material into the branch pipe 32, and the runoff branch pipe 32, the centralized pipe 31 and the constant temperature heating pipe 34 are re-injected into the fermentation kettle body 1.

[0033] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
