Description

TECHNICAL FIELD

[0001] The utility model relates to the field of microbial fermentation technology, especially to a device for monitoring the temperature of microbial fermentation. BACKGROUND

[0002] Microbial fermentation refers to the process of using microorganisms to convert raw materials into products needed by humans through specific metabolic pathways under suitable conditions. In the process of microbial fermentation, temperature fluctuations may affect the metabolism of the bacteria and the quality of the product. Therefore, it is necessary to monitor and control the temperature in the fermentation tank in real time to ensure the growth of the bacteria and the production of the product. The traditional temperature monitoring method mainly involves inserting a mechanical clamp or a temperature probe directly into the liquid or culture medium in the fermentation tank to monitor the temperature changes in the fermentation tank. The mechanical clamping method can only measure the temperature at a local position in the fermentation tank, which has low adaptability. The direct insertion of the probe may cause the loss of some heat in the tank, thereby affecting the accuracy of the measurement results.

[0003] Chinese patent CN220472825U proposes a clamping type microbial fermentation temperature monitoring device. By setting up clamping plates, handles, connecting plates, springs, gears, and shafts, the temperature sensor is fixed between the two clamping plates. The clamping plates are close to each other under the elastic action of the spring, and the temperature controller is fixed, which simplifies the disassembly and assembly steps and improves the disassembly and assembly efficiency. However, due to the size limitation of the mechanical clamping assembly, only the temperature at a local position in the fermentation tank can be monitored. The fermentation liquid in the fermentation tank is usually not uniformly mixed, which may lead to different temperature values at different positions. The temperature monitoring value at the local position may deviate from the actual value, which may affect the judgment and control of the operator and further affect the production efficiency and product quality of the fermentation production. SUMMARY

[0004] To solve the problem of poor flexibility and deviation of the measurement results from the actual value in the prior art microbial fermentation temperature monitoring device, the utility model provides a microbial fermentation temperature monitoring device, which comprises a magnet, a wire casing, and a temperature monitor.
