Description

TECHNICAL FIELD

[0001] The utility model mainly relates to fermentation temperature control technical field, concretely relates to a fermentation temperature automatic control device. BACKGROUND

[0002] In the modern industrial production and scientific research field, fermentation process is widely used, covering food, pharmaceutical, chemical and many other industries. As one of the key factors affecting fermentation effect, fermentation temperature plays a decisive role in the quality, yield and efficiency of fermentation products.

[0003] Traditional fermentation temperature control method has many drawbacks. Early fermentation tank usually uses simple heating or cooling device, such as ordinary electric heating wire heating and natural air cooling or water cooling. This method not only has low temperature control precision, but also is difficult to stabilize the fermentation temperature in a suitable range, and the temperature regulation response speed is slow. When the temperature fluctuates during fermentation, it cannot be adjusted in time and effectively, resulting in poor fermentation effect and difficult to ensure product quality.

[0004] With the development of technology, some fermentation tanks introduce automatic temperature control concept, but there are still many problems. Some devices are equipped with temperature sensor and simple control system, but the heating and cooling system are independent, without effective cooperative working mechanism. In actual operation, it often appears that heating is excessive or cooling is insufficient, resulting in large temperature fluctuation in the fermentation tank. In addition, these devices often lack auxiliary temperature regulation means, when the environmental temperature changes greatly or a large amount of heat is generated during fermentation, it is difficult to ensure that the fermentation temperature is always in the best state.

[0005] For example, in the food fermentation industry, unstable temperature may change the taste, flavor and nutritional components of fermented products, reducing the market competitiveness of products; in the pharmaceutical industry, deviation of fermentation temperature may affect the synthesis of active ingredients of drugs, leading to unqualified drug quality, and even potential threat to patients' health.

[0006] In summary, the existing fermentation temperature control device has obvious deficiencies in temperature control precision, response speed, cooperative work and response to complex working conditions. Therefore, it is of great practical significance to develop a fermentation temperature automatic control device that can realize accurate, fast and stable fermentation temperature control, to improve the quality of fermented products, improve production efficiency and reduce production cost.

[0008] The utility model provides a fermentation temperature automatic control device to solve the technical problems in the above background technology.

[0009] 2. Technical Solution:

[0010] To achieve the above objectives, the technical solution provided by this utility model is as follows: an automatic fermentation temperature control device, comprising a fermentation tank assembly, the fermentation tank assembly comprising a fermentation tank body, a heat transfer sleeve fitted on the outer side of the fermentation tank body, a spiral tube mounting cavity opened on the inner wall of the heat transfer sleeve, a heating spiral tube and a cooling spiral tube alternately arranged in the spiral tube mounting cavity, the heating spiral tube being connected to a heat transfer oil heating system, and the cooling spiral tube being connected to a cooling water tank.

[0011] Preferably, an insulation shell is fitted on the outer side of the heat transfer jacket, and a temperature sensor is installed inside the insulation shell. The temperature sensor is electrically connected to the control box and monitors the surface temperature of the fermenter body in real time.

[0012] Preferably, the heat transfer oil heating system includes an oil inlet pipe and an oil outlet pipe. One end of the oil inlet pipe is connected to the oil outlet of the heat transfer oil heating system, and the other end is connected to the heating spiral tube. The oil outlet pipe is connected to the other end of the heating spiral tube.

[0013] Preferably, the cooling water tank is provided with an inlet pipe and an outlet pipe. The inlet pipe is connected to a pipeline pump. The inlet pipe and the pipeline pump pressurize the cooling water in the tank and deliver it to the cooling spiral pipe, and then return it to the cooling water tank through the outlet pipe.

[0014] 3. Beneficial effects:

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0016] This invention uses a temperature sensor to monitor the temperature in real time, and a control box automatically controls the operation of the heating and cooling systems according to the set temperature range. This achieves precise temperature control within the fermenter, providing a stable temperature environment for the fermentation process and improving the quality and yield of the fermented products. The entire temperature control process involves the coordinated work of the temperature sensor, control box, heat transfer oil heating system, cooling water tank, and auxiliary cooling mechanism, achieving automated control, reducing manual intervention, and improving work efficiency and temperature control accuracy.

[0017] In this invention, the heating and cooling spiral tubes are alternately arranged within the spiral tube mounting cavity of the heat transfer jacket, increasing the contact area with the jacket and improving heat transfer efficiency, enabling the fermenter body to heat up or cool down rapidly. The auxiliary cooling mechanism further enhances the cooling effect when the fermenter body temperature is high, preventing excessively high temperatures from adversely affecting the fermentation process. The insulation shell reduces heat loss from the fermenter body, lowering energy consumption, and also reduces the influence of external ambient temperature on the internal temperature of the fermenter body, improving temperature control stability. Through the synergistic effect of the heating and cooling spiral tubes, the different temperature requirements of various fermentation processes can be met, resulting in a wide temperature control range.

[0031] See attached document Figs. 1-6 An automatic fermentation temperature control device includes a fermentation tank assembly 1, which includes a fermentation tank body 11. A heat transfer sleeve 14 is fitted on the outer side of the fermentation tank body 11. A spiral tube mounting cavity 17 is opened on the inner wall of the heat transfer sleeve 14. A heating spiral tube 15 and a cooling spiral tube 16 are alternately arranged in the spiral tube mounting cavity 17. The heating spiral tube 15 is connected to a heat transfer oil heating system 2, and the cooling spiral tube 16 is connected to a cooling water tank 3.

[0032] The heat transfer jacket 14 is covered with an insulation shell 12. A temperature sensor 13 is installed inside the insulation shell 12. The temperature sensor 13 is electrically connected to the control box and monitors the surface temperature of the fermenter body 11 in real time.

[0033] The heat transfer oil heating system 2 includes an oil inlet pipe 21 and an oil outlet pipe 22. One end of the oil inlet pipe 21 is connected to the oil outlet of the heat transfer oil heating system 2, and the other end is connected to the heating spiral tube 15. The oil outlet pipe 22 is connected to the other end of the heating spiral tube 15.

[0034] The cooling water tank 3 is equipped with an inlet pipe 31 and an outlet pipe 32. The inlet pipe 31 is connected to a pipeline pump. The inlet pipe 31 and the pipeline pump pressurize the cooling water in the tank and deliver it to the cooling spiral pipe 16, and then return it to the cooling water tank 3 through the outlet pipe 32.

[0035] Working principle:

[0036] Temperature sensor 13 inside the insulation shell 12 monitors the surface temperature of the fermenter body 11 in real time and transmits the temperature data to the control box. When the temperature data received by the control box shows that the temperature inside the fermenter body 11 is lower than the set lower limit temperature, the control box controls the heat transfer oil heating system 2 to start working. After being heated in the heat transfer oil heating system 2, the heat transfer oil enters the heating spiral tube 15 through the oil inlet pipe 21. The heat is transferred to the fermenter body 11 through the heat transfer jacket 14, heating the material inside the fermenter body 11. The heated heat transfer oil flows back to the heat transfer oil heating system 2 through the oil outlet pipe 22 for reheating and circulation.

[0037] When the temperature data received by the control box shows that the temperature inside the fermenter body 11 is higher than the set upper limit temperature, the control box controls the pipeline pump to start. The pipeline pump pressurizes the cooling water in the cooling water tank 3 and delivers it to the cooling spiral tube 16 through the inlet pipe 31. The cooling water flows in the cooling spiral tube 16, absorbing the heat transferred from the fermenter body 11 through the heat transfer jacket 14, thus cooling the fermenter body 11. The cooled water, after absorbing heat, flows back to the cooling water tank 3 through the outlet pipe 32.

[0038] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, 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 modifications and improvements 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.
